A-13 Sectra Server for DOS Page vii Sectra Server for DOS Page viii About This Manual This manual provides step-by-step instructions for installing Sectra Token Ring Server for DOS and configuring the program for your token ring network. The manual also describes how to use the Sectra program to: * Monitor the configuration and status of your network * Log ring events * Troubleshoot problems * Control node access to each ring in the network What You Should Know This manual is intended for network administrators and others who need to monitor, troubleshoot, and control access to networks. To use this guide successfully, you should know the basic principles of token ring operation, including the kinds of errors that can occur on token ring networks. Document Conventions In this manual, the following symbols are used as part of command and message formats. [ ] Characters that appear between brackets indicate user input and must be entered exactly as shown. You can use any combination of upper and lowercase letters. For example "select [No] and press ". { } Words that appear between braces are variables. If this word in braces is part of a command, replace the word with information relevant to the task. If a braced word (or phrase) is in a description of a message displayed by Sectra, Sectra replaces the word (or phrase) with information relevant to the message. For example, the phrase "{n} abort delimiters generated by {node_1}" in the manual could be displayed in the program "8 abort delimiters generated by 0001c80600c5". < > Angle brackets enclose specified keys, for example . Sectra Server for DOS Page P-1 Sectra Server for DOS Page P-2 CHAPTER ONE Product Overview This chapter, which provides an overview of Sectra Server for DOS, contains two sections: * Features and Benefits * Overview of Sectra Operations Features and Benefits Sectra Token Ring Server for DOS (hereafter called "Sectra Server for DOS") is a network management program that allows you to monitor, troubleshoot and control node access on IEEE 802.5 token ring networks. Sectra Server for DOS resides on a workstation and can monitor and control up to two rings that have an adapter in the workstation. Sectra Server for DOS works with NetWare, Banyan VINES, LAN Manager, IBM PC Lan, and other IEEE 802.5 compliant LAN operating systems to provide a comprehensive network management system. Sectra Server for DOS enables you to: * Monitor the token ring configuration. Sectra Server for DOS maintains a database of all nodes and rings on the network. Sectra Server also allows you to specify names for rings and nodes, as well as other significant information. In addition, Sectra Server allows you to display nodes that are on the network. * Monitor network errors and events in real time. From Sectra, you can view token ring errors and other significant network events as they occur. * Receive automatic notification of token ring error conditions. Sectra Server can automatically make a log entry when a specified type of error or event occurs. Sectra Server can also send an alarm notice to a Sectra client operating on the network. * Review recent network history. Sectra Server for DOS maintains a log of recent token ring events that you can examine. A separate log is maintained for each ring in the workstation. You can specify the types of events that are logged. * Isolate token ring faults. Sectra Server for DOS maintains error counters for each node and compiles error information for each ring in the network. This information is essential for identifying and troubleshooting network problems and for isolating errors between nodes. Sectra Server for DOS Page 1-1 * Control node access to the network. Sectra Server for DOS allows you to specify the days of the week and the hours of the day during which a node is allowed on a ring, thereby improving network security. You can access Sectra Server for DOS directly from the workstation, or from a Sectra client located on the network. Using a LAN utility such as Lan Assist allows remote access to Sectra Server for DOS, thereby enabling you to monitor the network from an off-site location. Overview of Sectra Server for DOS Operations Sectra Server for DOS reads certain Medium Access Control (MAC) frames from each ring in the network. From these frames, Sectra Server for DOS extracts information about the configuration of rings, ring errors, and information about other significant events. After extracting pertinent information from MAC frames, Sectra Server for DOS updates its error counters. Sectra Server for DOS tracks errors for each node and compiles errors for each ring in the network. Sectra Server for DOS also updates the configuration information it maintains for each ring and node. This information includes such items as a node's address and the number of nodes inserted into a ring. Sectra Server for DOS maintains node information in such a way that the order of nodes on the ring is preserved in the database. This allows you to isolate errors between nodes. Sectra Server for DOS automatically maintains error and configuration information about nodes and rings in the network. You can supply additional node information (such as the physical location of the node) that Sectra Server for DOS will store in its database. In addition to extracting error information from MAC frames, Sectra Server for DOS extracts information about other significant events that occur on the network. If you wish, Sectra Server for DOS can log these events on a ring-by-ring basis. You can specify that Sectra Server for DOS log only certain types of events (configuration events, error events, etc.). You can tell Sectra Server for DOS to post an alarm to the event log when certain error conditions occur on a ring. Sectra Server for DOS can thus notify you of error conditions that you consider important. When Sectra Server for DOS detects an error condition that you have specified to trigger an alarm, an active Sectra client on the network can display an alarm message. Sectra Server for DOS Page 1-2 The Client/Server Relationship The Sectra Token Ring Management System is a network management program that allows you to monitor and control IEEE 802.5 token ring networks. The Sectra Token Ring Management System is made up of three components: * The Sectra Token Ring Server for NetWare * The Sectra Token Ring Server for DOS * The Sectra Token Ring Client for Windows The Sectra Server for NetWare is a NetWare Loadable Module (NLM), which means that you can load and run Sectra under Novell's Netware 386 network operating system (NOS). Because the Sectra server resides on the network server, it can monitor and control access to any ring that has a Thomas-Conrad token ring adapter in the server. Sectra thus allows you to monitor and control access to an entire token ring network from a single vantage point. Since the Sectra server module runs on a network server, it is accessible even when the rest of the network is down. The Sectra Server for DOS is a DOS executable program that has the same functions and features as the Sectra server for NetWare. The Sectra server for DOS is designed to run on a wide variety of hardware. It can monitor and control access on up to two rings that have an adapter in the workstation. It does not require a Thomas-Conrad token ring card to operate and will work with most popular network operating systems. The Sectra Token Ring Server for NetWare or Sectra Token Ring Server for DOS collect data; the Sectra Client displays the data. Separating data collection and data presentation maximizes responsiveness for both the network administrator and the network users. The Sectra Server for Netware and the Sectra Server for DOS can monitor and control access to rings that they are attached to. The Sectra Server for NetWare, running on the network server, can monitor up to eight rings that have a Thomas-Conrad adapter in the server. The Sectra Server for DOS, running in a workstation, can monitor up to two rings in the workstation using any vendor's token ring adapters. In addition to collecting data and controlling ring access locally, both the Sectra server for NetWare and the Sectra Server for DOS act as agents for the Sectra client. The Sectra Client for Windows displays the data collected by agents on the network (either the Sectra Server for NetWare or the Sectra Server for DOS). You can have many clients displaying data from one server, or conversely, one client displaying data from many different servers monitoring many different rings. Sectra Server for DOS Page 1-3 The Sectra client also allows any user with appropriate privileges to monitor and control access to any ring on the network with a Sectra server. You can use the Sectra client for Windows from any network workstation that runs Microsoft Windows, even if the workstation is on Ethernet, ARCNET, or TCNS (Thomas-Conrad Networking System). Sectra Server for DOS Page 1-4 CHAPTER TWO Installation and Configuration This chapter describes how to install Sectra Server for DOS and how to configure the program for your particular network. This chapter contains the following sections: * Installing LLC drivers * Installing ODI drivers supporting promiscuous mode * Unloading Sectra Server for DOS * Configuring Sectra Server for DOS * Specifying Ring Parameters System Requirements You must have the following hardware to run Sectra Server for DOS: * An IBM PC compatible 286 or above * A minimum of 1Mbyte of RAM * An 80-column display * A hard drive * One token ring adapter for each ring to be monitored. * DOS 3.0 or higher or compatible operating system * IPX for communications to a Sectra Client For continuous monitoring, Sectra Server for DOS requires a dedicated workstation. For troubleshooting or performance checking, you can use any workstation on the ring that meets the system requirements. LLC Driver Installation To install and configure Sectra for DOS using an adapter with LLC support, take the following steps: 1 Make sure that the workstation you are going to use meets the requirements listed above. 2 Create a subdirectory for the program files. For example you could create a directory and name it SECTRATR or another name that you want. 3 Copy the contents of the program disk to the subdirectory that you created in step 2. You can use the DOS copy command with the asterisk (*) to copy all of the files. For example: [COPY A:\*.* C:\{Subdirectory Name}] 4 Load the Sectra for DOS initialization module by typing SECTLLC. Sectra Server for DOS Page 2-1 5 Load IPX if you desire client communications 6 Start Sectra for DOS by typing SECTRA from the SECTRATR subdirectory (or the subdirectory that you created.) This starts a batch file that will load BTRIEVE and start the Sectra for DOS program. When you exit the program normally, this batch file will unload BTREIVE. NOTE The Sectra for DOS initialization module, SECTLLC, can also be loaded as a device driver. To load SECTLLC as a device driver, insert the following statement in the your CONFIG.SYS file: DEVICE=SECTLLC.EXE Make sure to place this statement after any statements in the CONFIG.SYS file that loads drivers for your adapter. The following shows examples of CONFIG.SYS and AUTOEXEC.BAT files for Thomas-Conrad and IBM token ring adapters. These are shown as samples, your file may have more statements for other devices. CONFIG.SYS (Thomas-Conrad) FILES=40 BUFFERS=30 DEVICE=DXMA0MOD.SYS DEVICE=TCCAHI.SYS DEVICE=TCTRLOAD.SYS DEVICE=TCTRCPI.SYS CONFIG.SYS (IBM) FILES=40 BUFFERS=30 DEVICE=DXMA0MOD.SYS DEVICE=DXMC0MOD.SYS AUTOEXEC.BAT (Thomas-Conrad or IBM) PATH = C:\, C:\DOS ... SECTRATR\SECTLLC IPX (If Client communications are required) (A LAN Support Driver required. You cannot use a native token ring driver (STOKEN)) NETX (If a network connection is required) CD \SECTRATR SECTRA NOTE SECTLLC must be loaded before either LANSUP.COM or IPX.COM depending on which driver is being used. Sectra Server for DOS Page 2-2 ODI Driver Installation To install and configure Sectra for DOS using a Thomas-Conrad adapter with a Thomas-Conrad ODI driver or other manufacturers adapter with an ODI driver that supports promiscuous mode, take the following steps: 1 Make sure that the workstation you are going to use meets the requirements listed on page 2-1. 2 Create a subdirectory for the program files. For example you could create a directory and name it SECTRATR or another name that you want. 3 Copy the contents of the program disk to the subdirectory that you created in step 2. You can use the DOS copy command with the asterisk (*) to copy all of the files. For example: [COPY A:\*.* C:\{Subdirectory Name}] 4 Place the following statements in your NET.CFG file: LINK DRIVER TCTOKSH PORT ? INT ? DMA REINSERT (Optional - See note below) any other statements NOTE With the Thomas-Conrad driver TCTOKSH, when the node is blocked, it will not reinsert itself into the ring. This conforms with the IEEE 802.5 specification. If the optional statement REINSERT is placed in the LINK section of the NET.CFG file, when the node is blocked, it can immediately reinsert it self. It is recommended that the REINSERT parameter be used when running Sectra for DOS. If the REINSERT parameter is not used and the MLID on the Sectra for DOS workstation receives the remove MAC frame, Sectra for DOS will terminate abnormally and the database will be corrupted. Sectra Server for DOS Page 2-3 5 To start Sectra Server for DOS, you can execute these commands in this order or place them in your STARTUP or AUTOEXEC file LSL (Provided with NetWare) MLID (TCTOKSH for Thomas-Conrad adapters) MLID (Optional - for second adapter) IPXODI (If client communications are required) NETX (If a network connection is required) SECTODI CD SECTRATR SECTRA To load the driver to support two adapter cards, repeat the MLID (TCTOKSH) statement in the AUTOEXEC.BAT file. If loading Sectra Server for DOS manually, repeat the command. The following shows examples of NET.CFG and AUTOEXEC.BAT files for Thomas-Conrad token ring adapters.

If problems persist, contact Thomas-Conrad technical services at 800-334-4112. Unloading Sectra Server for DOS Sectra Server for DOS is designed to run continuously on your workstation in order to provide constant network monitoring and immediate troubleshooting capabilities. If you wish to unload Sectra Server for DOS press at the Select Ring menu. You will be asked for a confirmation before Sectra Server for DOS is unloaded. If Sectra for DOS is not unloaded in this in this manner, (ie if the computer is turned off or reset) the data files will be damaged. If the data files are damaged, Sectra will rebuild these files the next time Sectra for DOS is loaded. SECTODI, if used, is unloaded by typing SECTODI /U. SECTLLC, if loaded from the command line, is unloaded by typing SECTLLC /U. If SECTLLC is loaded as a device driver (loaded in the CONFIG.SYS file), it cannot be removed using the /U switch. Sectra Server for DOS Page 2-4 Configuring Sectra Server for DOS After installing Sectra Server for DOS, you need to perform the configuration sequence for each ring that has an adapter in the workstation. If you have just installed Sectra Server for DOS, the Select Ring menu is now displayed on the workstation monitor. If you are reconfiguring Sectra Server for DOS, press until the Select Ring menu is displayed. Configure Sectra Server for DOS for the selected ring as follows: 1 Use the up and down arrow keys to select the desired ring from the Select Ring menu. If you have just installed Sectra Server for DOS, each ring is identified as either Primary or Secondary server. When you select a ring, Sectra Server for DOS displays the View/Manage Ring menu. Select the Specify Ring Parameters option to display the Specify Ring Parameters window. 旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� 넬컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴커� 납Thomas-Conrad Corp.

This is a temporary condition. * Normal - The ring is operating normally--that is, not continuously transmitting beacon frames. * Beaconing - The ring is transmitting beacon frames, indicating a hard error (an error that prevents normal ring operation). * Re-organizing - Due to changes on the ring, Sectra Server for DOS is temporarily reorganizing its database for the ring. * Card not Available - The adapter or driver is not installed or cannot be accessed by Sectra Server for DOS. * Adapter Error - The adapter has had an error condition and is attempting to correct it. This is a temporary condition. If the adapter is not able to correct the problem, this error will change to Card not Available. The adapter is not collecting data while in this state. Sectra Server for DOS Page 3-3 Key Descriptions This section describes the cursor-movement and editing keys available in menus and windows. Except for minor differences in the way alphanumeric characters are treated, cursor movement keys and editing keys are used in the same way as for Novell applications. Keys Defined for All Menus And Windows Displays help information for the current menu or window. Sectra Server for DOS displays a help screen for five (5) minutes before returning to the program window. Pressing the escape key will also exit you from a help screen. Help Screen Keys Exits the help screen and displays the menu or window from which help was requested. Displays the previous page of the help screen. Displays the next page of the help screen. Displays the first page of the help screen. Displays the last page of the help screen. Menu Keys Displays the previous menu or window. Moves cursor up or down one line, respectively. Moves cursor to the first list item on the current page. Moves cursor to the last list item on the current page. Selects the first menu choice starting with that character. Keys for Data Entry Windows Moves cursor up or down one line, respectively. Moves cursor to the first item in the window. Moves cursor to the last item in the window. Sectra Server for DOS Page 3-4 Enters edit mode for a field. The cursor blinks on the first character in the field. Data entry is by default in typeover mode. The key toggles between insert and typeover. Pressing a second time moves the cursor to the next field. While in edit mode, resets the field to its previous value (before edits were made) and repositions the cursor at the beginning of the field. Pressing after you are through editing requests confirmation of any changes you made and exits to the previous menu. Deletes the character to the left of the cursor. Moves the cursor to the left or right one character, respectively, without deleting a character. Deletes the character the cursor is on. Enters the character at the cursor position. Characters are entered in write-over mode: a new character writes over an existing character.

Normal - The ring is operating normally--that is, only transmitting AMP and SMP frames. Beaconing - The ring is transmitting beacon frames, indicating a hard error (an error that prevents normal ring operation). Re-organizing - Due to changes on the ring, Sectra Server for DOS is temporarily reorganizing its database for the ring. Card not Available - The adapter or driver is not installed or cannot be accessed by Sectra Server for DOS. Adapter Error - The adapter has had an error condition and is attempting to correct it. This is a temporary condition. If the adapter is not able to correct the problem, this error will change to Card not Available. The adapter is not collecting data while in this state.

Sectra Server for DOS Page 5-4 CHAPTER SIX Viewing and Managing Node Data Sectra Server for DOS allows you to view a great deal of data about each node in a ring and to manage this data efficiently. This chapter, which describes how to view and manage node data, contains the following sections: * Viewing a Node's Data * Viewing a Node's Error Counters * Adding a Node to the Sectra Server for DOS Database * Modifying a Node's Data * Deleting a Node from the Sectra Server for DOS Database Viewing a Node's Data When you select View Nodes from the View/Manage Ring, you display the Node Data Window for Inserted nodes, which displays information about nodes currently inserted into the ring. On the left side of the window, the inserted nodes are displayed in the order in which they occur on the ring, beginning with the adapter in the workstation.

The Node Error Counters window displays the error counters that Sectra maintains for a selected node. Press from either of the Node Data windows to display the Node Error Counters window. To view an error summary of all nodes in the ring, display the Error Summary window (see Chapter 4 for more information). The node error counters are divided into three categories: * Beacon frames - A beacon frame indicates that a hard error occurred. Hard errors totally disrupt normal ring operation. No user data can be transferred on the ring while beacon frames are being transmitted. * Isolating Errors - An isolating error is a soft error that can be isolated to a specific area of the ring, such as the token ring adapter, the nearest active upstream neighbor (NAUN), the adapter cable, or a Multistation Access Unit (MAU). Soft errors can disrupt token ring operation, thus degrading performance. However, soft errors do not totally disable the ring, as do hard errors. * Non-isolating errors - A non-isolating error is a soft error that cannot be isolated to a specific area of the ring. See Chapter 9 for a detailed description of hard and soft errors, including each type of isolating and non-isolating error recognized by Sectra Server for DOS. Two error counts are provided for each counter: a session count and a total count. The session count indicates how many errors have occurred since the node was last inserted into the ring. The total count indicates how many errors have occurred since Sectra Server for DOS started counting errors for the node. Press to reset the selected node's counters. Fields Beacon The number of beacon frames transmitted Frames: from the node. Isolating Errors: Abort The number of abort delimiter frames Delimiter: transmitted from the node. Sectra Server for DOS Page 6-9 A/C: The number of A/C errors detected by the node. Burst: The number of burst errors detected by the node. Internal: The number of internal errors that have occurred at the node. Line: The number of line errors detected by the node. Other The number of other isolating errors detected Isolating: by the node. Non-isolating Errors: Frame Copy: The number of frame copy errors detected by the node. Frequency: The number of frequency errors detected by the node. Lost Frame: The number of lost frame errors detected by the node. Receiver The number of receiver congestion errors Congestion: detected by the node. Token: The number of token errors detected by the node. Other Non- The number of other non-isolating errors isolating: detected by the node. For All Counters: Counters The date and time when the node's error Reset: counters were last reset. Errors/ The number of errors per minute for the node Minute: during the current viewing session. Keys Help Displays the data for the node selected on the left side of the window.

Sectra Server for DOS Page 8-3 Sectra Server for DOS Page 8-4 CHAPTER NINE Troubleshooting and Preventive Maintenance This chapter describes how to use Sectra Server for DOS to troubleshoot and maintain your token ring network. This chapter contains the following sections: * Types of Token Ring Errors * Error Detection and Recovery Protocols * Establishing a Fault Domain * Troubleshooting Techniques * Preventive Maintenance Types of Token Ring Errors Token ring errors are classified as one of two types: Hard errors - Hard errors prevent user data from being transmitted on the ring. In addition, hard errors require that the ring be reconfigured, either automatically by ring recovery protocols or manually by replacing the faulty hardware. The node immediately downstream from the hard error reports the error by transmitting beacon MAC frames. The beacon frame itself is not a hard error but is the token ring's response to a hard error. From the beacon frame, Sectra Server for DOS extracts the addresses of the nodes that mark the fault domain for the hard error (the section of the ring in which the error probably occurred). Soft errors - Soft errors do not totally halt the transmission of user data on the ring but, in sufficiently large numbers, may cause the ring's performance to degrade noticeably. The node detecting a soft error reports it by transmitting a report soft error MAC frame. (Actually, in this frame, a node transmits a summary of soft errors collected by the node.) Soft errors are classified as isolating or non-isolating errors. An isolating error indicates the two nodes between which an error occurred. Non-isolating errors do not isolate the error to a particular part of the ring. Tables 9-1 and 9-2 briefly describes the isolating and non-isolating soft errors. In any ring there are a certain amount of soft errors over a period of time. This is normal. You must monitor your ring to determine what is a normal level of soft errors.

Before attempting to troubleshoot token ring errors, you should have a general understanding of how token ring networks report errors and attempt to recover from them. This information will help you distinguish genuine error conditions from spurious ones and help you to troubleshoot problems. Active and Standby Monitor Functions One adapter on the ring is the active monitor. The monitor contention process (described below) determines which adapter becomes the active monitor. The active monitor performs the following functions to ensure that the ring operates properly: Sectra Server for DOS Page 9-3 * Generates the ring's master clock, which the other nodes use as a reference for transmit and receive operations * Introduces a delay into the ring to ensure that a token can be completely transmitted before being taken off the ring by the transmitting node * Starts the ring poll process (described below) by transmitting an active monitor present (AMP) frame * Monitors the ring poll process to ensure that it proceeds correctly * Every 10 milliseconds, verifies that a good token is on the ring * Purges a frame if the node that transmitted the frame fails to do so * Generates a new token if one is needed All other nodes serve as standby monitors. Each standby monitor performs the following functions to determine whether the active monitor is functioning properly: * Every 2.6 seconds, verifies that it has received a good token. If a standby monitor has not received a good token within this time, either there is no active monitor or the active monitor is not functioning properly. * Detects the absence of AMP frames. The absence of AMP frames indicates that there is no active monitor or that the active monitor is not functioning properly * Detects frequency errors, which indicate that there is no active monitor or that the active monitor is not functioning properly. (A frequency error is a non- isolating soft error that occurs when a node detects that the ring clock generated by the active monitor differs too much from the node's internal clock.) * If the active monitor is not functioning properly, starts the monitor contention process to select a new active monitor Ring Poll Process The ring poll process (also known as the neighbor notification process) allows each inserted node to obtain the address of its Nearest Active Upstream Neighbor (NAUN). This information enables a node to indicate the fault domain for beacon events and for isolating soft errors. The boundaries of a fault domain are the address of the node transmitting the frame and the address of its NAUN. Sectra Server for DOS Page 9-4 The active monitor starts the ring poll process by transmitting an AMP frame, which provides the downstream node with the active monitor's address. The downstream node then transmits an SMP frame, which indicates its own address to the next downstream node. This process continues until each node has identified itself to its downstream neighbor. Ring Insertion Process Before an adapter inserts itself into the ring, it tests itself and verifies the integrity of the ring status. The ring insertion process consists of the following steps: * Lobe media test * Physical insertion into the ring and monitor check * Address verification * Ring polling * Request for initialization When the adapter is not physically inserted into the ring, the adapter's transmit signal is looped back into the adapter's receiver. Before the adapter inserts itself into the ring, it performs a lobe media test, which is a loopback test that verifies that the adapter is receiving the same data that it is transmitting. Before the adapter physically inserts itself into the ring, it must successfully transmit and receive many lobe media test MAC frames and successfully send one or more duplicate address test (DAT) frames to itself. After passing the lobe media check, the adapter outputs a DC current, thereby activating a relay that physically inserts the adapter's transmit and receive pairs into the ring. If the adapter does not detect the presence of an active monitor through the receipt of an AMP frame, SMP frame, or ring purge frame within a certain period of time, it starts the monitor contention process (described below). After the adapter inserts itself into the ring and detects the presence of an active monitor, the adapter verifies that it has a unique node address on the ring by transmitting DAT MAC frames to itself. If another node in the ring indicates that it has the same address, the adapter deinserts itself from the ring and terminates the insertion process. Once the adapter determines that it has a unique address on the ring, it participates in the ring poll process (described above). During this process, the adapter receives the address of its nearest active upstream neighbor (NAUN) and provides its own address to its downstream neighbor. The adapter then requests operating parameters from the node that serves as the parameter server for the ring. The Sectra Server for DOS Page 9-5 parameter server sends initialization information to adapters that are inserting into the ring, thereby ensuring that all adapters use the same operating parameters. These parameters replace the adapter's default parameters used during the ring insertion process. Monitor Contention Process The monitor contention process establishes one node in the ring as the active monitor. This process starts when a standby monitor detects that there is no properly functioning active monitor in the ring. A standby monitor starts the process by transmitting a claim token MAC frame. On receiving such a frame, each node enters the contention process. The node with the highest numbered address wins the contention and becomes the active monitor, whereupon it immediately performs a ring purge (described below). Ring Purge Process The ring purge process puts the ring into a known state so that normal operation can resume. The active monitor starts the ring purge process when it detects a token error or after becoming the active monitor through monitor contention. To start the ring purge process, the active monitor transmits a ring purge MAC frame. On receiving this same frame, the active monitor transmits a free token to start normal ring operation. If errors prevent the active monitor from receiving a ring purge MAC frame, the active monitor restarts the monitor contention process. If the monitor contention process times out, the first node to detect this condition starts the beaconing process (described below). Beaconing Reconfiguration and Removal The beacon process attempts to recover the ring from a hard error. If the recovery succeeds, the ring resumes normal operation. If the recovery fails, constant beaconing on the ring indicates that the ring is disabled and requires manual intervention. Beaconing begins whenever normal recovery methods (a ring purge followed by the monitor contention process) fail to clear an error from the ring. The adapter that first detects that monitor contention has timed out starts the beaconing process by transmitting a beacon MAC frame every 20 milliseconds. This adapter is in beacon transmit mode. On receiving a beacon frame, all other nodes in the ring enter beacon repeat mode, in which they repeat the beacon frame transmitted by the adapter in beacon transmit mode. Sectra Server for DOS Page 9-6 If an adapter in beacon repeat mode does not receive a beacon frame within a 200-millisecond period, it assumes that the ring has recovered from beaconing. The adapter then starts or enters the monitor contention process. The error that caused the beaconing is located between the receiver of the adapter that is in beacon transmit mode and the transmitter of the NAUN. One or both of these two adapters, which mark the boundary of the fault domain, may attempt to verify its own operation by automatically removing itself from the ring and executing its media lobe test (described above). If the NAUN receives eight consecutive beacon frames from its downstream neighbor, it performs the reconfiguration and removal process. If the adapter in beacon transmit mode receives its own beacon frame for 26 seconds (indicating that the removal of the NAUN from the ring did not solve the problem), it performs the reconfiguration and removal process. If either adapter fails its media lobe test, it remains physically deinserted from the ring. If either adapter passes the test, it reinserts itself into the ring and enters the monitor contention process. If the monitor contention process fails, beaconing resumes, resulting in constant beaconing on the ring. Establishing a Fault Domain Before troubleshooting a token ring problem, you should establish a fault domain for the problem. A fault domain is a limited area of the ring in which the error probably occurred (or is occurring). A fault domain is bounded by two nodes. Beacon event messages and isolating soft error messages identify the two nodes that mark the fault domain for the beacon event or soft error, respectively. One node reported the beacon event or soft error. The other node is the reporting node's nearest active upstream neighbor (NAUN). A fault domain contains the following field replaceable units (FRUs): * The adapter that reported the error condition * The reporting adapter's lobe (the cable between the adapter and the MAU) * The MAU to which the reporting adapter is attached * The NAUN's adapter * The NAUN's lobe * The MAU to which the NAUN is attached (which could be the same MAU to which the reporting adapter is attached or a different MAU) * The ring-in/ring-out cable between the MAUs (if the two adapters are on different MAUs) Sectra Server for DOS Page 9-7 Sectra Server for DOS provides two ways to determine the boundaries of a fault domain: * The easiest way is to display the Error Summary window for the ring and see which node is reporting beacon events or isolating errors. This node and its NAUN mark the boundaries of the fault domain. * The second way to determine a fault domain is to examine the error log for the ring and get the addresses for the two nodes from a beacon event message or an isolating soft error message. Once you have determined a fault domain, you can use adapter diagnostics (such as Thomas-Conrad's Ring Tools, which is supplied with each Thomas-Conrad adapter) or replace FRUs to isolate the failing FRU within the fault domain. Troubleshooting Techniques Symptoms of network problems, what you or users on your network experience when the network is not operating properly, can be divided into three general classes: * A node can't insert itself into the ring. * Ring performance is noticeably degraded and numerous errors are occurring. * The ring is in a beaconing state or has recovered from beaconing. A Node Can't Insert into the Ring If a node is unable to insert into the ring, the user at the node will not be able to access the network. In this case, use the following troubleshooting procedure: 1 If necessary, check whether unauthorized nodes are allowed in the ring. Both the View/Manage Ring menu and the Ring Data window indicate this. 2 Use the Node Data Window for Inactive Nodes to check whether the node is an authorized node and whether the node is allowed to be in the ring at this time. 3 If the node is allowed to be in the ring at this time, review any other configuration information displayed for the node. You may find, for example, that the driver is not suitable for the adapter or that there is a mismatch between the adapter speed and the ring speed. Sectra Server for DOS Page 9-8 4 Check that the adapter's lobe cable (the cable running from the network adapter to the MAU) is properly connected to both the adapter and the MAU. 5 Verify that the adapter is configured properly for the ring. (For example, make sure that the ring speed is correct.) If the adapter is a Thomas-Conrad adapter, insert the Ring Tools diskette into a workstation and enter ringtools to invoke the Ring Tools diagnostic program. Then select Adapter Settings to display the configuration settings for the adapter. If the adapter is not a Thomas-Conrad adapter, you may have to check the jumper and switch settings on the adapter. 6 Check whether the MAU port is malfunctioning by plugging the adapter into another MAU port. If the adapter can now insert into the ring, the previously used MAU port is the problem. 7 If the adapter is using a locally administered address (a user-assigned address), verify that the adapter address is unique on the ring. If the adapter is a Thomas-Conrad adapter, run Ring Tools to verify the address. Otherwise, turn off the locally administered address. If the adapter can insert into the ring when the locally administered address is turned off, the problem is a duplicate address. 8 Verify that the adapter is functioning properly by running the adapter diagnostics on the adapter (Ring Tools on a Thomas-Conrad adapter). You can also replace the adapter with a known-good adapter and try to insert the new adapter into the ring. If the adapter fails the diagnostic or if a known-good adapter can insert into the ring, the problem is the adapter. 9 Test the cabling between the adapter and MAU by replacing it with a known-good cable or replacing the workstation with a known-good workstation. If the problem goes away in the first case or does not go away in the second case, the cabling is the problem. 10 Check whether the adapter uses bus master mode (the fastest mode of transferring data between the workstation and the ring) and whether the adapter's workstation supports bus master mode. Note that some so-called IBM-compatible computers do not actually support bus master mode. If possible, configure the adapter for I/O mapped mode and try to insert it into the ring. You can also replace the adapter with a known-good adapter. If a known-good adapter cannot insert into the ring and if known-good Sectra Server for DOS Page 9-9 cabling is being used, the problem is probably that the workstation does not support bus master mode. 11 If the above procedure does not isolate the problem, call Thomas-Conrad Technical Services toll-free 24-hours-a-day 7 days-a-week at (800) 334-4112. Performance Degradation There are two major causes of performance degradation, excessive network traffic and excessive soft errors. During peak periods of use, your network may carry more traffic than it can service at optimum speed. If this performance degradation becomes a problem, you may want to split the ring into two or more smaller rings. Otherwise, consider limiting the access of high-traffic nodes to hours when other nodes are not using the network very much. You should also make sure that the number of allowed nodes on the ring (which you can specify in the Specify Ring Parameters window) is not exceeded. Excessive soft errors can also cause a noticeable degradation of ring performance. How many soft errors are excessive is specific to each ring. The following guidelines, however, are valid for all rings: * Rings with many nodes are more likely to experience soft errors than rings with few nodes. * Rings running at 16 Mbps are more likely to experience soft errors than rings running at 4 Mbps. * Rings with Type 3 media (unshielded twisted-pair), which is more susceptible to ring jitter, are more likely to experience soft errors than rings with Type 1 media (shielded twisted-pair). You should become familiar enough with each ring on your network to get an idea of how many soft errors in a given period is normal. Keep in mind that inserting and removing nodes from the network causes soft errors. If your ring is very stable, if no nodes are inserting into or deinserting from the ring, you should see very few soft errors, if any, on the ring. As explained earlier in this chapter, soft errors can be isolating or non-isolating errors. Both types of errors often occur together. In fact, when troubleshooting soft errors, you should look for isolating soft errors, which indicate a fault domain. Except for the receiver Sectra Server for DOS Page 9-10 congestion error, non-isolating errors do not provide much useful information for troubleshooting. (The receiver congestion error points to a problem with the workstation at the node that reported the error.) Use the following troubleshooting procedure to troubleshoot isolating soft errors: 1 Look at the Error Summary window for the ring to determine which node is reporting the isolating soft errors. This node and its NAUN are the boundaries of the fault domain. You can also look at the soft error messages in the event log for the ring. The messages identify the two nodes that establish the fault domain for a soft error. 2 Remove one of these adapters from the ring. If the soft errors go away, this adapter is probably the cause of the soft errors. If the adapter is a Thomas-Conrad adapter, insert the Ring Tools diskette into a workstation and enter ringtools to invoke the Ring Tools diagnostic program. Then run Ring Tools on the adapter. If the adapter is not a Thomas-Conrad adapter, run the manufacturer's diagnostics (if available) on the adapter. You can also try reinserting the adapter back into the ring. If this causes excessive soft errors (once the ring has stabilized after the insertion), this adapter is the problem. 3 If there are still excessive soft errors, repeat step 2 for the other adapter indicated in the fault domain. 4 If steps 2 and 3 did not isolate the problem, replace the lobe cable for one of the adapters in the fault domain with a known-good lobe cable. Then reinsert the adapter into the ring. If the soft errors go away, the lobe cable is the problem. If the soft errors do not go away, replace the cable for the other adapter in the fault domain. If the soft errors go away, this lobe cable is the problem. 5 If there are still excessive soft errors, determine whether the fault domain includes one MAU or two MAUs. 6 If the fault domain includes only one MAU, this MAU is probably the problem. Reinitialize the MAU by powering it down and then powering it up or by using an appropriate reset tool. If this doesn't solve the problem, replace the defective MAU with a known- good MAU if you have one. The soft errors should go Sectra Server for DOS Page 9-11 away. If you don't have a spare MAU, connect the affected adapters to another MAU if possible. Otherwise, try to reroute the ring cabling to bypass the defective MAU. If this does not solve the problem, call Thomas-Conrad Technical Services toll-free 24-hours-a-day, 7 days-a-week at (800) 334-4112. 7 If the fault domain includes two MAUs, disconnect the cable between the MAUs. If the soft errors go away, the problem is the cable. 8 If there are still excessive soft errors, the problem is probably one of the MAUs in the fault domain. Disconnect the other ring-in/ring-out cable from one of the MAUs. If the soft errors go away, this MAU is the problem. If this does not solve the problem, do the same thing to other MAU. If the soft errors go away, this MAU is the problem. 9 If there are still excessive soft errors, call Thomas- Conrad Technical Services toll-free 24-hours-a-day 7 days-a-week at (800) 334-4112. Beaconing A ring experiencing beaconing can either beacon continuously, or recover from beaconing, in which case one or more nodes is removed from the ring. A troubleshooting procedure is provided for each of these situations. The Ring Has Recovered from Beaconing If the ring has recovered from a beacon event, use the following troubleshooting procedure to determine whether either or both of the nodes in the fault domain is malfunctioning: 1 Look at the Error Summary window for the ring to determine which node reported the beacon events. This node and its nearest NAUN are the boundaries of the fault domain. You can also look at the beacon event messages in the event log for the ring. The messages identify the two nodes that establish the fault domain for the beacon event. 2 Either of these adapters may have removed itself from the ring. If the adapter is a Thomas-Conrad adapter, insert the Ring Tools diskette into a workstation and enter ringtools to invoke the Ring Tools diagnostic program. If the adapter is not a Sectra Server for DOS Page 9-12 Thomas-Conrad adapter, run the manufacturer's diagnostics (if available) on the adapter. If no adapter diagnostics are available, replace the removed adapter with a known-good adapter. If the adapter fails its diagnostics or if a known-good adapter works, the problem is the removed adapter. 3 If both adapters pass their diagnostics or if the known-good adapter does not work, the problem may be a MAU port. Reinitialize the MAU to which the suspect adapter is connected by powering it down and then powering it up or by using an appropriate reset tool. If this doesn't solve the problem, plug each of the affected adapters into a different MAU port. If the adapter works, the problem is the MAU port into which the adapter was previously plugged. If necessary, replace the MAU. 4 If you cannot locate the cause of beaconing, monitor the fault domain to see whether further errors occur. The Ring is Beaconing Continuously If the ring is beaconing continuously, use the following troubleshooting procedure: 1 Look at the Error Summary window for the ring to determine which node is reporting the beacon events. This node and its NAUN are the boundaries of the fault domain. You can also look at the beacon event messages in the event log for the ring. The messages identify the two nodes that establish the fault domain for the beacon event. 2 Remove one of these adapters from the ring. If the beaconing goes away, this adapter is probably the cause of the beaconing. Reinsert the adapter into the ring. If beaconing resumes, this adapter is the problem. Verify this by testing the affected adapter with adapter diagnostics if available. If the adapter is a Thomas-Conrad adapter, insert the Ring Tools diskette into a workstation and enter ringtools to invoke the Ring Tools diagnostic program. Then run Ring Tools on the adapter. 3 If the ring is still beaconing after you remove one adapter, repeat step 2 for the other adapter indicated in the beacon message. 4 If the ring is still beaconing, determine whether the fault domain includes one MAU or two MAUs. Sectra Server for DOS Page 9-13 5 If the fault domain includes only one MAU, this MAU is probably the problem. Reinitialize the MAU by powering it down and then powering it up or by using an appropriate reset tool. If this doesn't solve the problem, replace the defective MAU with a known- good MAU if you have one. Beaconing should stop. If you don't have a spare MAU, connect the affected adapters to another MAU, if possible. Otherwise, try to reroute the ring cabling to bypass the end of the MAU (ring-in or ring-out) that may be causing the problem. If you still cannot restore normal ring operation, call Thomas-Conrad Technical Services toll-free 24-hours-a-day, 7 days-a-week at (800) 334-4112. 6 If the fault domain includes two MAUs, disconnect the cable between the MAUs. If the beaconing stops, the problem is the cable. 7 If beaconing does not stop, the problem is probably one of the MAUs in the fault domain. Disconnect the other ring-in/ring-out cable from one of the MAUs. If beaconing stops, this MAU is the problem. If the ring is still beaconing, do the same thing to other MAU. If beaconing stops, this MAU is the problem. 8 If the ring is still beaconing, call Thomas-Conrad Technical Services toll-free 24-hours-a-day, 7 days- a-week at (800) 334-4112. Preventive Maintenance and Security You can use Sectra Server for DOS to perform preventive maintenance for your token ring network and to monitor network security. Preventive maintenance involves monitoring the operation of your network to spot and correct problems before they cause a serious disruption of network operation. Sectra Server for DOS enables you to do this by providing both overviews and detailed records of network operation. To get a quick overview of what's been happening on the network, look at the View/Manage Ring menu for each ring to see whether any beacon events and/or soft errors have occurred. Look at the Error Summary window see where in the ring any errors have been occurring. To get a more detailed picture of network operation, display the Event Log Monitor window to look at network events as they occur or display the Event Log History window to examine the event log for the ring. If you notice that certain conditions, such as too many nodes on the ring or an Sectra Server for DOS Page 9-14 excessive number of soft errors per minute, tend to precede serious problems, use the Alarm Definition window to set up alarms for these conditions. Sectra Server for DOS gives you several ways of monitoring ring security. Both the View/Manage Ring menu and the Ring Data window indicate whether any unauthorized nodes are in the ring. Use the Alarm Definition window to direct Sectra Server for DOS to post an alarm when any of the following occurs: * Sectra Server for DOS removes a node from the ring * An unauthorized node attempts to gain access to the ring * Sectra Server for DOS sees a node on the ring for the first time. Use the Node Data Window for Inactive Nodes to examine configuration information about nodes that Sectra Server for DOS has removed from the ring. If you have specified in the Select Events to Log window that Sectra Server for DOS log certain Sectra Server for DOS control events, you can also look at the event messages concerning the removal of nodes from the ring. Sectra Server for DOS Page 9-15 Sectra Server for DOS Page 9-16 APPENDIX A Sectra Server for DOS Event Descriptions This appendix describes the events that Sectra Server for DOS can display in the Event Log Monitor window and can log to a ring's event log file (accessed with the Event Log History window). This appendix contains the following sections: * Event Types * Event Descriptions Event Types Sectra Server for DOS recognizes six types of events: * Events that are always logged. Sectra Server for DOS always logs these events if event logging is turned on. However, Sectra Server for DOS does not generate an alarm when an event of this type occurs. The following events are always logged: Alarm - {cause_of_alarm} Event logging started Event logging stopped * Sectra Server for DOS events. These events indicate when Sectra Server for DOS has sent an alarm, when a user has selected events for Sectra Server for DOS to display and log, or when Sectra Server for DOS itself has been loaded or unloaded: Client Started Client Stopped Event filter set Sectra Server for DOS for DOS loaded Sectra Server for DOS for DOS unloaded * Normal events. These events occur as part of normal ring operation: Active monitor present from {node} Claim token event from {node} New active monitor from {node} Ring purge event from {node} Standby monitor present from {n} nodes - last: {node} * Configuration events. These events indicate a change in the ring configuration: {node} inserted into ring ({n} nodes in ring) {node} left ring ({n} nodes currently in ring) {node} seen for first time ({n} nodes in ring) Sectra Server for DOS Page A-1 Ring configuration change completed ({n} nodes in ring) Ring configuration changing * Error events. These events result from hard or soft errors that occur on the ring: Abort delimiter: {n} from {node_1} to {node_2} A/C error: {n} between {node_1} and {node_2} Active monitor error event from {node} Beacon frame between node_1 and node_2 Burst error: {n} between {node_1} and {node_2} Frame copy error: {n} reported by node Frequency error: {n} reported by node Internal error: {n} between {node_1} and {node_2} Line error: {n} between {node_1} and {node_2} Lost frame: {n} reported by node MAC frame(s) lost Neighbor notification incomplete event - last: {node} Receiver congestion: {n} reported by node Token error: {n} reported by node * Sectra Server for DOS control events. These events indicate when Sectra Server for DOS has removed a node from the ring, when a user has blocked a node from entering the ring, or when a user resets the node or ring counters: {node} blocked {node} counters reset {node_1} NAUN changed to {node_2} {node} removed Ring counters reset Event Descriptions Each event message is described below. The event messages are arranged in alphabetical order. Abort delimiter: {n} from {node_1} to {node_2} Event type: Error Description: {n} abort delimiter errors generated by {node_1} were detected by its downstream neighbor, {node_2}. An abort delimiter is an isolating soft error that occurs when a node stops transmitting a frame before the frame is completed. Probable A recoverable or unrecoverable error Cause: internal to the node's workstation, or a token that is not terminated properly (a Sectra Server for DOS Page A-2 token in which the third byte is not an ending delimiter). Action: If an excessive number of these errors occurs, replace the {node_1} and/or {node_2} adapters. If this does not solve the problem, follow the troubleshooting procedure for performance degradation in Chapter 9. A/C error: {n} between {node_1} and {node_2} Event type: Error Description: {n} access control (A/C) errors occurred between {node_1} and {node_2}. This an isolating soft error that occurs during the ring poll process when a node is unable to properly participate in this process. (Specifically, the Access Control (A/C) field of an active monitor present (AMP) frame or standby monitor present (SMP) frame has an incorrect value.) The error is generated by {node_1} and detected by its downstream neighbor, {node_2}. Possible This error can occur when a node inserts Cause: itself into the ring or deinserts itself from the ring. An excessive number of these errors can indicate a malfunctioning adapter at {node_1}. Action: If an excessive number of these errors occurs, follow the troubleshooting procedure for performance degradation in Chapter 9. Active monitor error event from {node} Event type: Error Description: The active monitor (node) has received a purge MAC frame or active monitor present (AMP) MAC frame that it did not transmit, or has received a claim token frame. This a non-isolating soft error indicating that there may be another active monitor on the ring. Possible The active monitor that sent the error Cause: frame may be malfunctioning, another node on the ring may incorrectly assume Sectra Server for DOS Page A-3 that it is the active monitor and may therefore be malfunctioning, or there may be another node with the same address as the active monitor (node). Action: Run adapter diagnostics on the adapter at the node identified in the event message. (Run Ring Tools on a Thomas-Conrad adapter.) If you don't have any adapter diagnostics, replace the adapter with a known-good adapter to see if the problem goes away. Active monitor present from node Event type: Normal Description: The active monitor (node) transmits an AMP frame to make the standby monitor nodes aware of its presence. The active monitor does this following a successful ring purge and every 7 seconds during normal operation to initiate the ring poll process. Action: None required. Alarm - {cause_of_alarm} Event type: Always Logged Description: Sectra Server for DOS detected an error condition for which it is supposed to post an alarm. The {cause_of_alarm} indicates which of the following error conditions caused the alarm: (too many) beacon frames (per minute), (too many) isolating errors (per minute), (too many) non-isolating errors (per minute), too many nodes on ring, node not allowed on ring, or node inserted for first time. Possible Any of the above-listed error conditions. Cause: Action: Determine which error condition caused the alarm and respond to the problem accordingly. Sectra Server for DOS Page A-4 Beacon frame between {node_1} and {node_2} Event type: Error Description: {node_2} transmitted a beacon frame, indicating that a hard error exists between its receiver and the transmitter of its NAUN, {node_1}. Possible A beacon frame always indicates that Cause: normal ring operation was or is being disrupted by a hard error. See Chapter 9 for a detailed description of what can cause beaconing. Action: Follow the appropriate troubleshooting procedure for beaconing, as described in Chapter 9. Burst error: n between {node_1} and {node_2} Event type: Error Description: {n} burst errors occurred between {node_1} and {node_2}. A burst error is an isolating soft error that occurs when {node_2} detects that no data was transmitted by {node_1} for 5.5 bit times between the start and the end of a frame. (A bit time is the amount of time required to transmit one bit on the ring.) Possible A break in cabling, an adapter being Cause: unplugged, a bumped wire, or normal ring activity, such as the insertion of a node into the ring. Action: If an excessive number of these errors occurs, follow the troubleshooting procedure for performance degradation described in Chapter 9. Claim token event from node Event type: Normal Description: A node started the monitor contention process by placing a claim token on the ring. Possible A new active monitor is needed for the Cause: ring. Sectra Server for DOS Page A-5 Action: None required. This is a normal occurrence on the ring. Client Started Event type: Sectra Server for DOS Description: A user started Sectra Server for DOS Client for Windows. The user is identified by the network username. Action: None required. Client Stopped Event type: Sectra Server for DOS Description: A user stopped Sectra Server for DOS Client for Windows. The user is identified by the network username. Action: None required. Event filter set Event type: Sectra Server for DOS Description: The event log filter for the ring was changed. Action: None required. Event logging started Event type: Always Logged Description: A user turned on Sectra Server for DOS event logging for the ring. Action: None required. Event logging stopped Event type: Always Logged Description: A user turned off Sectra Server for DOS event logging for the ring. Action: None required. Sectra Server for DOS Page A-6 Frame copy error: {n} reported by node Event type: Error Description: {node} reported {n} frame copy errors. A frame copy error is a non-isolating soft error that occurs when a frame addressed to a node is marked as having been read by another node. The node for which the frame was intended reports the error. Possible The line is broken, there was electrical Cause: noise on the line, or there is a duplicate node address. Action: If an excessive number of these errors has occurred, look for isolating errors that occurred at approximately the same time as the frame copy error so that you can establish a fault domain (the section of the ring that is probably causing the problem). Frequency error: {n} reported by node Event type: Error Description: {node} reported {n} frequency errors. A frequency error is a non-isolating soft error that occurs when a node detects that the ring clock generated by the active monitor differs too much from the node's internal clock. Possible The node's lobe cable (the cable between Cause: the adapter and the MAU) is too long. The node's adapter could be malfunctioning. Action: Run adapter diagnostics on the affected adapter (Ring Tools on a Thomas-Conrad adapter), or replace the adapter with a known-good adapter. If the adapter is not the problem, replace the {node's} lobe cable with a shorter cable. Internal error: {n} between {node_1} and {node_2} Event type: Error Description: {n} internal errors occurred between {node_1} and {node_2}. An internal error is Sectra Server for DOS Page A-7 an isolating soft error that occurs when an adapter discovers an error internal to itself or its workstation that prevents the node from functioning properly in the ring. Possible The adapter at the affected node may be Cause: malfunctioning. Action: Run adapter diagnostics on the affected adapter, replace this adapter with a known-good adapter, try the affected adapter with a new workstation, or try a known-good workstation with the affected adapter. Line error: {n} between {node_1} and {node_2} Event type: Error Description: {n} line errors occurred between {node_1} and {node_2}. A line error is an isolating error that occurs when any of the following happens: a token or a frame is repeated by a node, a token or frame contains corrupted fields, or a frame check sequence (FCS) error occurs. An FCS error indicates that data may be corrupted in the frame Possible A node inserting into or deinserting from Cause: the ring, a bad lobe cable (the cable between the adapter and the MAU), or electrical noise. Action: If an excessive number of line errors has occurred, check whether a node inserted into or deinserted from the ring just before the line errors occurred. If the errors persist, replace the {node's} lobe cable with a known-good cable. Lost frame: n reported by node Event type: Error Description: A lost frame error is a non-isolating error that occurs when a node does not receive a frame that it has transmitted. Possible A node inserted into or deinserted from Cause: the ring, or the {node's} adapter or lobe cable is bad. Sectra Server for DOS Page A-8 Action: Check whether a node inserted into or deinserted from the ring just before the line errors occurred. If the errors persist, run adapter diagnostics on the affected adapter (Ring Tools on a Thomas-Conrad adapter), or replace the adapter with a known-good adapter. Replace the {node's} lobe cable with a known-good cable. Neighbor notification incomplete event - last: {node} Event type: Error Description: This error is a non-isolating soft error that occurs when one of the standby monitors did not complete the ring poll process. {node} is the last node to complete the sequence. Possible The downstream neighbor of {node} could Cause: be malfunctioning. Action: If there is an excessive number of these errors, replace {node's} downstream neighbor. New active monitor from {node} Event type: Normal Description: {node} has won the monitor contention and is now the new active monitor. Action: None required. This is a normal occurrence. {node} blocked Event type: Sectra Server for DOS control Description: A user has blocked {node's} access to the ring by pressing the key when the Node Data Window for Inserted Nodes is displayed. Action: None required. Sectra Server for DOS Page A-9 node counters reset Event type: Sectra Server for DOS control Description: A user reset the Sectra Server for DOS error counters for the node. Action: None required. {node} inserted into ring ({n} nodes in ring) Event type: Configuration Description: {node} inserted itself into the ring. {n} nodes, including the newly inserted node, are now inserted into the ring. Action: None required. node left ring ({n} {nodes} currently in ring) Event type: Configuration Description: {node} removed itself from the ring. n nodes are now inserted into the ring. Action: None required. {node_1} NAUN changed to {node_2} Event type: Configuration Description: The nearest active upstream neighbor (NAUN) of {node_1} changed to {node_2}. Possible A node inserted into the ring between Cause: {node_1} and its former NAUN or deinserted from the ring between {node_1} and its former NAUN. Action: None required. This is a normal occurrence. Sectra Server for DOS Page A-10 {node} removed Event type: Sectra Server for DOS control Description: Sectra Server for DOS removed {node} from the ring. Possible The node is not authorized to be in the Cause: ring or is not allowed to be in the ring at this time. Action: Check whether the node is currently authorized to be in the ring. {node} seen for first time ({n} {nodes} in ring) Event type: Configuration Description: This is the first time that {node} has inserted itself into the ring since Sectra Server for DOS was last loaded. If the node was an unauthorized node or was not allowed to be in the ring at this time, Sectra Server for DOS removed the node from the ring. Action: Check whether the node is authorized to be on the ring. Receiver congestion: {n} reported by node Event type: Error Description: {node} reported {n} receiver congestion errors. A receiver congestion error occurs when a workstation loses a frame addressed to it because of a lack of buffer space. Possible The workstation's operation is too slow or Cause: has come to a halt. The problem could also be that one or more workstations is sending an excessive number of frames to the indicated node. Action: If an excessive number of these errors has occurred, return the workstation to normal operation, reduce the workstation workload, or replace the workstation with a faster one. Sectra Server for DOS Page A-11 Ring configuration change completed ({n} nodes in ring) Event type: Configuration Description: The configuration of the ring has changed. Sectra Server for DOS has completed reorganizing its database to account for the change. Possible Any event that causes one or more rings Cause: to insert into or deinsert from the ring. Action: None, unless a hard error caused the reconfiguration; in that case, follow the appropriate troubleshooting procedure for beaconing described in Chapter 9. Ring configuration changing Event type: Configuration Description: The configuration of the ring is changing. Sectra Server for DOS is reorganizing its database to account for the change. Possible Any event that causes one or more rings Cause: to insert into or deinsert from the ring. Action: None, unless a hard error caused the reconfiguration; in that case, follow the appropriate troubleshooting procedure for beaconing described in Chapter 9. Ring counters reset Event type: Sectra Server for DOS control Description: The Sectra Server for DOS ring counters for the ring were reset. Action: None required. Ring purge event from {node} Event type: Normal Description: The active monitor {node} has initiated a ring purge operation. Possible A node, on assuming the role of the new Cause: active monitor, always performs a ring purge. The active monitor also performs a ring purge in response to error Sectra Server for DOS Page A-12 conditions on the ring. (See Chapter 9 for a description of the ring purge process.) Action: None, unless the number of ring purges are excessive; in that case, troubleshoot any isolating soft errors associated with the ring purge. Use the troubleshooting procedure for performance degradation described in Chapter 9. Sectra Server for DOS for DOS loaded Event type: Sectra Server for DOS Description: The Sectra Server for DOS program was loaded. Action: None required. Sectra Server for DOS for DOS unloaded Event type: Sectra Server for DOS Description: The Sectra Server for DOS program was unloaded. Action: None required. Standby monitor present from {n} nodes - last: {node} Event type: Normal Description: This is a summary of the standby monitor present (SMPs) frames transmitted by the standby monitors as part of the ring poll process. This message indicates that {n} nodes transmitted SMP packets and that {node} was the last node in the ring to do so. Action: None required. This is a normal occurrence. Token error: {n} reported by node Event type: Error Description: {n} token errors occurred and were reported by {node}. A token error is a non-isolating soft error reported by the active monitor when it has to place a new token on the ring because an error occurred during token passing on the ring or because it Sectra Server for DOS Page A-13 did not detect a token or frame within 10 milliseconds. Possible This error is quite common when a node Cause: inserts itself into the ring or removes itself from the ring. If an excessive number of these error occurs, there is probably a cabling problem. Action: If you suspect a problem, check for isolating soft errors that occurred when the token error occurred. Check the cabling in the fault domain indicated by any such isolating soft errors. (A fault domain is the section of the ring in which the error probably occurred.) Sectra Server for DOS Page A-14
