HP OpenView Network Management
Product Numbers B1009A for Series 300, 400 B1024A for Series 600, 700,
800 B1034A for SunSPARC
Welcome to HP OpenView
HP OpenView Network Node Manager provides fault, configuration, and
performance management for multivendor TCP/IP (Transmission Control
Protocol/Internet Protocol) networks on a site or campus. Based on
international standards, Network Node Manager manages network devices
that are IP-addressable and/or run the Simple Network Management
Protocol (SNMP). Network Node Manager 2.0 runs on HP 9000 Series 300,
400, 600, 700, and 800 computers with HP-UX 7.0 or later. Additionally,
Network Node Manager runs on SunSPARCstations with SunOS version 4.1 or
later.
Part of the HP OpenView family of system and network management
products, Network Node Manager includes a graphical user interface based
on OSF/Motif, as well as on-line help and documentation to allow network
administrators to put the product to work within minutes instead of
days.
With the explosion of TCP/IP-based local and wide area networks,
corporate Internets, and client-server computing, network administrators
need solutions today to minimize network downtime and maximize their
productivity. Network Node Manager maximizes productivity by greatly
reducing the amount of time administrators spend on network
troubleshooting and administration tasks.

Network Node Manager 2.0 offers a number of enhancements over 1.0. To
guarantee true multivendor interoperability, HP has included the ability
to build applications that use vendor-specific SNMP MIB objects and
vendor-specific traps, as well as the ability to add applications to the
menu bars. It also includes historical data reporting and user-defined
thresholds. All of these new features can be put to use quickly and
without any programming.
HP OpenView Network Node Manager solves the critical problems
customers face today in deploying large networks.

Benefit
Ensures effective management of a wide range of network devices and
systems from other vendors as well as from HP.
Network administrators can use Network Node Manager to effectively
manage their networks within a few minutes of installation.
Saves network administrators hours of entering configuration
information once a network is discovered. Network Node Manager tracks
on-going changes as they occur.
Lets users manage any SNMP device without programming, including
standard and vendor-specific Management Information Base (MIB) objects;
menu-driven sets provide control.
Gives network administrators a single place to look to determine the
overall health of the network and a head start toward maximizing network
availability.
Eliminates unnecessary interaction with the network management
system.
Allows network administrators to work from a central location rather
than pursuing problems around the facility.
Protects investment in tools the network administrator is already
using and ensures a smooth transition from present network management
tools to Network Node Manager.
Network administrators can get the current and historical network
information they need to understand the dynamic aspects of their network
for network planning and troubleshooting.
Discovery
5
Network Node Manager automatically discovers, maps, and continuously
monitors all network and system resources across a TCP/IP network. As
the network changes, the Discovery capability automatically shows the
changes and updates the network map.
Single View Management
New and existing user or third-party applications can be easily
integrated in a matter of minutes, protecting the user's investment.
Application Builder
Users and developers can quickly build applications to manage network
devices and resources that use the industry-pervasive, multivendor
Simple Network Management Protocol (SNMP).
Dynamic Data Collection and Thresholds
Users can get the current and historical network information they need
to understand the dynamic aspects of their network for network planning
and troubleshooting.
The chart outlines the general features and benefits of Network Node
Manager.
Network Node Manager's management tools currently fall into three
major categories: fault management, configuration/system management, and
performance management. The following sections explain the innovative
capabilities of HP OpenView Network Node Manager in more detail.
Fault Management
Network Status
Continual connectivity verification for IP-addressable devices is
performed automatically using the TCP/IP utility ping. Results are
color-coded on the network map (green for up status, red for down
status, and yellow for marginal status).
Continuous Network Discovery
After a map is generated, Network Node Manager continues to find new
nodes as they are added and automatically determines if nodes are
deleted from the network. Other topology changes, such as the addition
and deletion of network interfaces, are also reflected in the map.
User-defined thresholds
Users can determine what is critical for their networks and set
thresholds, which, if exceeded, will generate an alarm. Network Node
Manager does threshold checking by polling nodes specified by the user.
Specific parameters on which thresholds can be set:
o CPU load on HP-UX and SunSPARC systems
o Percentage of disk space used on HP-UX and SunSPARC systems
o Number of packets received with errors
o Number of packets sent with errors
o Number of collisions on the network
o Number of frames received with CRC errors
Event Notification
6
A variety of sources generate alarms within the network management
system. These alarms are presented to the network administrator via the
network map, an event browser window, and an event log.
Specific alarms may indicate a network failure:
o Threshold exceeded for one of the conditions described
o Failure to communicate with a host performing routing
o An SNMP node started or stopped forwarding packets
o An SNMP node has the wrong link address for another node
o An SNMP node did not respond to an SNMP request
o SNMP nodes do not agree on a link address for a node
o Agent network interface is down
o Network is critical due to the number of nodes down
o A particular network segment is critical
Menu Encapsulation
Users can easily add their own applications to the Network Node Manager
menu bar by simply specifying a title and action for the menu item in a
registration file. Users utilize a node selected on the map as the input
to a command launched from a menu item.
Applications launched from menus can include any executable command
or shell script. For simple TTY applications, Network Node Manager
automatically creates a terminal window to contain the output. For
X-Window applications, the display is automatically output to the
screen.
Trap Formatting and Actions
Many SNMP devices send traps (events) that are specific to that device.
With trap formatting and actions, the network administrator can:
o Specify the text message that will be logged when a particular
vendor-specific trap arrives at the management station
o Specify a program to be executed when a particular trap arrives, such
as calling the network administrator's beeper
o Execute shell scripts or any executable command upon the arrival of a
trap
Remote Diagnostics
Tools that facilitate troubleshooting have been integrated with the
network map. Tests may be initiated quickly on nodes selected from the
map with the mouse. Remote tests include:
o IP test uses ping to check physical connectivity from the manager
system to a remote node or between two remote nodes
o TCP test performs a TCP connection to determine if a connection can be
established to a remote node
o SNMP test tests if a remote node has an SNMP agent running
Easy information access
To expedite problem resolution, users have quick access to essential
information by selecting nodes from the map and choosing menu items.
This information includes:
o Addressing information for remote systems including IP, link level
(Ethernet), and subnet mask values
o Contents of a remote system ARP cache
o Disk space utilization on HP-UX systems
7
o A record of the most recent events received by the manager application
from a particular node
o Interface information and statistics for remote systems
o Contents of a remote system routing table
o A list of network services operational on a remote system
o Contents of the TCP connection table for a remote system
Manage/Unmanage
Network administrators have the capability to define the scope of what
is managed and to determine which parts of the network must be
discovered and monitored at any given time. Managed nodes are polled for
status and configuration on a regular basis. Unmanaged nodes are not
polled except when specified by the network administrator.
Remote Terminal
Users have convenient access to remote systems via virtual terminal
applications through the network map. Terminal types are hpterm for
terminal emulation to HP systems, xterm to most other UNIX(r) systems,
and vt3k for use with HP 3000 systems.
Map Snapshots
The current network map can be saved and used later to help determine
what has changed in the network.
Find Network Routes
Users can view graphical and textual displays of the route a packet
takes through the network between any two systems.
Command Line Commands
Network Node Manager includes a number of commands that can be executed
directly from the command line. These commands allow the user to access
most of the information on the network via a dumb terminal. These
commands include:
o Get an SNMP value (snmpget)
o Set an SNMP value (snmpset)
o Send an SNMP trap (snmptrap)
o Query a node with SNMP Get Next Request (snmpnext)
o Query a node repeatedly with SNMP Get Next Requests (snmpwalk)
o Print out the map database
o Find the route between two nodes (findroute)
o Take a snapshot of the map database (mapsnap)
o Check connectivity between two nodes (netcheck)
o Check a node's complete configuration (nmdemandpoll)
o Check an HP-UX or Sun node's disk space (rbdf)
o List network information of a remote mode (rnetstat)
o Remote packet echo from one node to another (rping)
Configuration and System Management
Dynamic Map
Automatic generation and continual updating of the network map and
associated database eliminates significant manual recordkeeping by
providing a central electronic record of network configuration
information.
8
HP Bridge/Hub Layout
The network administrator has a clear view of a network's physical
configuration to aid in both troubleshooting and inventory.
Network Node Manager automatically discovers HP's IP-addressable
10-10 Bridges, remote bridges, EtherTwist hubs, and fiber hubs. When
these devices are discovered, Network Node Manager automatically lays
them out properly on the map. In the case of bridges, it automatically
detects which nodes are on which side of the bridge. In the case of the
EtherTwist and fiber hubs, it detects which ports have nodes connected
and which have other hubs connected and lays out the map accordingly.
Easy Map Editing
Users can represent information on the map that cannot be dynamically
discovered, such as the addition of non-IP devices and details of the
physical topology. This mouse-driven editing includes the ability to:
o Move objects
o Add objects to the map
o Delete objects
o Add connections between objects
o Delete connections between objects
o Change object types
MIB Browser
Users can easily point-and-click their way down and up any SNMP device
MIB tree. Any object's value can be retrieved as a single value;
multiple objects can also be retrieved in table form. Numerical objects
can also be graphed in real-time. Setable MIB objects can be set through
this same dialog box. Set security is provided via community names.
Application Builder
Users have the ability to put the query of an MIB object or objects into
Network Node Manager menus. The query can get a single MIB object value,
a table of values, or a real-time graph. Used in combination with the
MIB Browser, MIB encapsulation gives both full SNMP interoperability and
flexible display of data.
Event Notification
Alarms generated due to configuration changes are:
o Network interface added to a system
o Network interface removed from a system
o New node discovered on the network
o Node removed from the network
o SNMP node started or stopped forwarding packets
o Node link level address changed
o Object identifier changed for a node
o System description changed for a node
o Node name changed
o Subnet mask changed
Map Snapshots
Snapshots record the current inventory of devices on the network,
eliminate manual recordkeeping, and provide a central electronic record
of network configuration information.
9
List of Remote Network Services
Users can access information about services available on a remote node.
Online Node Description
With a single mouse button click, information can be retrieved about a
node's location, contact name, type of node, and network configuration.
In addition, the network administrator can add free-form comments to the
node description, such as serial numbers and other relevant information.
Integration of SAM
Remote system administration for HP-UX systems can be driven from the
network map. By using HP System Administration Manager (SAM), you can
configure software on systems on the network.
Locating Map Objects
Users can locate objects by various attributes. This is useful for
inventory control and for finding systems in large networks. Attributes
that can be searched include:
o Host name
o IP address
o Link (Ethernet) address
o Object type (gateway, workstation, PC, mainframe, etc.)
o Nodes running SNMP
o String search in comments
Performance Management
Real-time monitoring of statistical information is provided in
easy-to-read graphical form. Data on peaks and averages associated with
the polling statistics is provided for easy trend identification and
problem tracking.
Dynamic Data Collection and Thresholds
Users can gather historical information for any numerical MIB element on
any SNMP device or group of devices. This information is saved to a
binary file and can be printed in a number of user-defined ASCII formats
or accessed directly. The saved files can be imported into popular
spreadsheets or SQL databases.
Users also can define thresholds on any numerical MIB element. Both
features can access MIB I, II and enterprise-specific objects.
Additional Features:
o Selections can be made using wildcard designations
o Event messages are triggered when thresholds are reached
o Users can define threshold reset values
o Time synchronization between manager and agent for data collection
o Menu driven
CPU Load of HP-UX and SunOS Systems
Users can monitor the relative CPU load of HP 9000 systems and SunSPARC
systems running the HP iOpenView TCP/IP Agent for SunSPARC.
Interface Traffic
Interface traffic includes the following:
o Incoming packets
10
o Incoming packets with errors
o Outgoing packets
o Outgoing packets with errors
Link Traffic
Users can monitor and graph the following LAN (Ethernet or IEEE 802.3)
card statistics for HP-UX SNMP node receptions and transmissions:
o Frames transmitted
o Frames received
o Frames deferred
o Collisions
o CRC errors
Polling Intervals
The user can decide how often to poll remote nodes for statistical
information. This is important because it lets the administrator control
the amount of network traffic generated to perform network management.
For busy networks, the interval between status polls can be increased to
hold down network traffic.
Managed Devices
IP-Addressable Devices
Network Node Manager will discover, map, and maintain status on all
IP-addressable devices on the network whether or not the devices run
SNMP agents. This includes HP 3000s, PCs, and numerous devices from
other vendors.
SNMP Devices
Using its extensible MIB capabilities, Network Node Manager 2.0 can
manage virtually any SNMP device whose agent conforms to standards.
Manageable devices include HP 9000 Series 300, 400, 600, 700, and 800
systems; HP/Apollo DN Series systems running TCP/IP; other UNIX systems
such as IBM RS/6000, DEC Ultrix, and Sun; virtually all TCP/IP routers,
HP bridges and EtherTwist hubs; many other vendors' network bridges and
multiport repeaters; and numerous other devices.
Connectivity
Connectivity between Network Node Manager and other vendors' SNMP agents
is supported for any agent that conforms to the SNMP specification RFC
1098 and to the first version of the Internet-standard Management
Information Base, which is covered in RFC 1066.
In addition, Network Node Manager can handle vendor-specific SNMP
objects through its extensibility features. As long as an SNMP device
MIB object description file is in proper ASN.1 format, Network Node
Manager can read it and access the special MIB objects. Using this
feature, Network Node Manager can manage virtually any SNMP device.
