1. Status of this Memo
This document is an Internet Draft. Internet Drafts are
working documents of the Internet Engineering Task Force
(IETF), its Areas, and its Working Groups. Note that other
groups may also distribute working documents as Internet
Drafts.
Internet Drafts are draft documents valid for a maximum of six
months. Internet Drafts may be updated, replaced, or obsoleted
by other documents at any time. It is not appropriate to use
Internet Drafts as reference material or to cite them other
than as a "working draft" or "work in progress."

Internet Draft directory to learn the current status of this
or any other Internet Draft.
2. Abstract
This memo defines an extension to the Management Information
Base (MIB) for use with network management protocols in
TCP/IP-based internets. In particular, it defines objects for
managing the Frame Relay Service.

3. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of
management.
o RFC 1213 defines MIB-II, the core set of managed objects
for the Internet suite of protocols.
o RFC 1445 which defines the administrative and other
architectural aspects of the framework.
o RFC 1448 which defines the protocol used for network
access to managed objects.
The Framework permits new objects to be defined for the
purpose of experimentation and evaluation.

Internet Draft Frame Relay Service MIB October 1, 1993
4. Object Definitions
Managed objects are accessed via a virtual information store,
termed the Management Information Base or MIB. Objects in the
MIB are defined using the subset of Abstract Syntax Notation
One (ASN.1) defined in the SMI. In particular, each object
object type is named by an OBJECT IDENTIFIER, an
administratively assigned name. The object type together with
an object instance serves to uniquely identify a specific
instantiation of the object. For human convenience, we often
use a textual string, termed the descriptor, to refer to the
object type.

5. Overview
These objects are used when the particular media being used to
manage is Frame Relay Service. At present, this applies to
these values of the ifType variable in the Internet-standard
MIB:
frameRelayService (44)
This section provides an overview and background of how to use
this MIB and other potential MIBs when managing a Frame Relay
Service.
Figure 1 shows the MIB stack that could be followed for
managing a Frame Relay Service. This is only an example and
not meant to be inclusive.

SCOPE OF MIB:
The Frame Relay Service MIB will only manage the Frame Relay
portion of the network.
This MIB will NOT be implemented on User Equipment (e.g.,
DTE), and the Frame Relay DTE MIB (RFC1315) should be used to
T. Brown (editor) Expires 5/1/94 [Page 5]
Internet Draft Frame Relay Service MIB October 1, 1993
manage those devices.
Frame Relay Service MIB is intended to be used for Customer
Network Management (CNM) of a Frame Relay Network Service. It
provides information that allows end-customers to obtain
performance monitoring, fault detection, and configuration
information about their Frame Relay Service.
By using this and other related MIBs, a customer's NMS can
monitor their PVCs and UNI/NNI logical ports. Internal
aspects of the network (e.g., switching elements, line cards,
and network routing tables) are outside the scope of this MIB.
The Customer's NMS will be able to access the SNMP proxy-agent
within the Frame Relay network using SNMP over UDP over IP
with IP encapsulated in Frame Relay according to RFC1490/ANSI
T1.617 Annex F. The customer thus has a PVC to the SNMP
proxy-agent. Alternate access mechanisms are possible. The
service capabilities include retrieving information and
receiving TRAPs. It is beyond the scope of this MIB to define
managed objects to monitor the physical layer. Existing
physical layer MIBs (e.g., DS1 MIB) and MIB II will be used as
possible. The Frame Relay Service SNMP MIB for CNM will not
contain any managed objects to monitor the physical layer.
This MIB primarily addresses Frame Relay PVCs. This MIB may
be extended at a later time to handle Frame Relay SVCs.
This MIB is only used to manage a single Frame Relay Service
offering from one network. Therefore, this MIB models a PVC
segment through one Frame Relay Network. See Figure 2. If
the customer's PVCs traverse multiple networks, then the
customer needs to poll multiple network proxy-agents to
retrieve their end-to-end view of their service. This MIB
will be implemented on a proxy-agent architecture within each
Frame Relay Service network. See Figure 2 and the Service
Management Architecture.

Figure 2. Multi-network PVC
Also, since the Frame Relay network is a shared network
amongst many Frame Relay subscribers, each subscriber will
only have access to their information (e.g., information with
respect to their interfaces and PVCs). Therefore, in order to
provide this capability, the Frame Relay PVC CNM proxy agent
should be able to support instance level granularity for MIB
views. See the Service Management Architecture.

Internet Draft Frame Relay Service MIB October 1, 1993
5.1. Frame Relay Service MIB Terminology
Access Channel - An access channel generically refers to the
DS1/E1 or DS3/E3-based UNI access channel or NNI access
channel across which frame relay data transits. An access
channel is the access pathway for a single stream of user
data.
Within a given T1 line, an access channel can denote any one
of the following:
o Unchannelized T1 - the entire T1 line is considered an access
channel. Each access channel is comprised of 24 T1 time slots.
o Channelized T1 - an access channel is any one of 24 channels.
Each access channel is comprised of a single T1 time slot.
o Fractional T1 - an access channel is a grouping of N T1 time
slots (NX56/64 Kbps, where N = 1-23 T1 Time slots per FT1 Access
Channel) that may be assigned in consecutive or non-consecutive
order.
Within a given E1 line, a channel can denote any one of the following:
o Unchannelized E1 - the entire E1 line is considered a single
access channel. Each access channel is comprised of 31 E1 time
slots.
o Channelized E1 - an access channel is any one of 31 channels.
Each access channel is comprised of a single E1 time slot.
o Fractional E1 - an access channel is a grouping of N E1 time
slots (NX64 Kbps, where N = 1-30 E1 time slots per FE1 access
channel) that may be assigned in consecutive or non-consecutive
order.
Within a given unformatted line, the entire unformatted line
is considered an access channel. Examples include RS-232,
V.35, V.36 and X.21 (non- switched).
Access Rate - The data rate of the access channel. The speed
of the user access channel determines how rapidly the end user
can inject data into the network.
Bc - The Committed Burst Size (Bc) is the maximum amount of
T. Brown (editor) Expires 5/1/94 [Page 8]
Internet Draft Frame Relay Service MIB October 1, 1993
subscriber data that the network agrees to transfer, under
normal conditions, during a time interval Tc. Bc is offered in
terms of bits.
Be - The Excess Burst Size (Be) is the maximum amount of
uncommitted data in excess of Bc that the network will attempt
to deliver during a time interval Tc. Be is offered in terms
of bits.
CIR - The Committed Information Rate (CIR) is the subscriber
data throughput that the network commits to supporting under
normal network conditions. CIR is averaged over the Committed
Rate Measurement Interval (Tc). CIR is offered in terms of
bits per second.
DLCI - Data Link Connection Identifier
Logical Port - This term is used to model the Frame Relay
"interface" on a device.
NNI - Network to Network Interface
Permanent Virtual Connection (PVC) - A virtual connection that
has its end-points and bearer capabilities defined at
subscription time.
Time slot (E1) - An octet within the 256-bit information field
in each E1 frame is defined as a time slot. Time slots are
position sensitive within the 256-bit information field.
Fractional E1 service is provided in contiguous or non-
contiguous time slot increments.
Time slot (T1) - An octet within the 192-bit information field
in each T1 frame is defined as a time slot. Time slots are
position sensitive within the 192-bit information field.
Fractional T1 service is provided in contiguous or non-
contiguous time slot increments.
UNI - User to Network Interface
N391 - Full status (status of all PVCs) polling counter
N392 - Error threshold
N393 - Monitored events count
T. Brown (editor) Expires 5/1/94 [Page 9]
Internet Draft Frame Relay Service MIB October 1, 1993
T391 - Link integrity verification polling timer
T392 - Polling verification timer
nT3 - Status enquiry timer
nN3 - Maximum status enquiry counter
5.2. Apply MIB II to a Frame Relay Service
Use the System Group to apply to the SNMP proxy-agent, since
the proxy-agent may be monitoring many Frame Relay devices in
one network. System Group applies to only one system. This
group is not instantiated.
sysDescr: ASCII string describing the SNMP proxy-agent.
Can be up to 255 characters long. This field is
generally used to indicate the network providers
identification and type of service offered.
sysObjectID: Unique OBJECT IDENTIFIER (OID) for the SNMP
proxy-agent.
sysUpTime: Clock in the SNMP proxy-agent; TimeTicks
in 1/100s of a second. Elapsed type since
the proxy-agent came on line.
sysContact: Contact for the SNMP proxy-agent.
ASCII string of up to 255 characters.
sysName: Domain name of the SNMP proxy-agent, for example,
acme.com
sysLocation: Location of the SNMP proxy-agent.
ASCII string of up to 255 characters.
sysServices: Services of the managed device. The value "2"
which implies that
the Frame Relay network is providing
a subnetwork level service is recommended.
This specifies how the Interfaces Group defined in MIB II
shall be used for the management of Frame Relay based
interfaces, and in conjunction with the Frame Relay Service
MIB module. This memo assumes the interpretation of the
T. Brown (editor) Expires 5/1/94 [Page 10]
Internet Draft Frame Relay Service MIB October 1, 1993
evolution of the Interfaces group to be in accordance with:
"The interfaces table (ifTable) contains information on the
managed resource's interfaces. Each sub- layer below the
internetwork layer of a network interface is considered an
interface." Thus, the ifTable allows the following Frame
Relay-based interfaces to be represented as table entries:
- Frame Relay interfaces in the Frame Relay equipment (e.g.,
switches, routers or networks) with Frame Relay interfaces.
This level is concerned with generic frame counts and
not with individual virtual connections.
In accordance with the guidelines of ifTable, frame counts per
virtual connection are not covered by ifTable, and are
considered interface specific and covered in the Frame Relay
Service MIB module. In order to interrelate the ifEntries
properly, the Interfaces Stack Group shall be supported.
Some specific interpretations of ifTable for Frame Relay
follow.
Object Use for the generic Frame Relay layer
====== =========================================
ifIndex Each Frame Relay port is represented by an ifEntry.
ifDescr Description of the Frame Relay interface.
ASCII string describing the UNI/NNI logical port.
Can be up to
255 characters long.
ifType The value allocated for Frame Relay Service
is equal to 44.
ifMtu Set to maximum frame size in octets for this
frame relay
logical port.
ifSpeed Peak bandwidth in bits per second available for use.
This could be the speed of the logical port and not
the access rate. Actual user information transfer
rate (i.e., access rate) of the
UNI or NNI logical
port in bits per second (this is not the clocking
speed). For example, it is 1,536,000 bits per
second for a DS1-based UNI/NNI logical port
T. Brown (editor) Expires 5/1/94 [Page 11]
Internet Draft Frame Relay Service MIB October 1, 1993
and 1,984,000 bits per second for an E1-based UNI/NNI
logical port.
ifPhysAddress The primary address for this logical port
assigned by the Frame Relay interface provider.
An octet string of zero length if no address is
used for this logical port.
ifAdminStatus Supports read-only access (initially).
The desired administrative status of the frame relay
logical port.
ifOperStatus The current operational status of the Frame Relay
UNI or NNI logical port.
ifLastChange The elapsed time since the last re-initialization of
the logical port.
The value of sysUpTime at the time the
logical port entered
its current operational state. If the current state
was entered prior to
the last re-initialization of the local network
management subsystem, then
this object contains a zero value.
ifInOctets The number of received octets.
This counter only counts octets from the
beginning of the frame relay header field to
the end of user data.
ifInUcastPkts The number of received unerrored,
unicast frames.
ifInDiscards The number of received frames discarded. Possible
reasons are as follows: policing,
congestion.
ifInErrors The number of received frames that are
discarded, because of an error.
Possible errors can be
the following: the frame relay frames
were too long or were too short, the frames
had an invalid or unrecognized DLCI values,
or incorrect header values.
T. Brown (editor) Expires 5/1/94 [Page 12]
Internet Draft Frame Relay Service MIB October 1, 1993
ifInUnknownProtos noSuchName
ifOutOctets The number of transmitted octets.
This counter only counts octets from the
beginning of the frame relay header field to
the end of user data.
ifOutUcastpkts The number of frames sent.
[Ed. note: Frame Relay switches provide counts of
transmitted frames and not of frames received
for transmission as required by the ifTable.
This is because the latter counter is
switch architecture dependent.
Comments are requested on this issue.]
ifOutDiscards The number of frames discarded in the
egress direction. Possible
reasons are as follows: policing,
congestion.
ifOutErrors The number of frames discarded in the egress
direction, because of errors.
Possible reason is transmit underruns.
ifSpecific Set to the OBJECT IDENTIFIER for
frLportIfIndex.frLportIfIndex for this ifEntry.
ifName noSuchName
ifInMulticastPkts The number of received unerrored,
multicast frames.
ifInBroadcastPkts noSuchName
ifOutMulticastPkts The number of sent unerrored,
multicast frames.
ifOutBroadcastPkts noSuchName
ifHCInOctets Only used for DS3-based (and greater) Frame
Relay logical ports.
The number of received octets.
This counter only counts octets from the
beginning of the frame relay header field to
the end of user data.
T. Brown (editor) Expires 5/1/94 [Page 13]
Internet Draft Frame Relay Service MIB October 1, 1993
ifHCOutOctets Only used for DS3-based (and greater) Frame
Relay logical ports.
The number of transmitted octets.
This counter only counts octets from the
beginning of the frame relay header field to
the end of user data.
ifLinkUpDownTrapEnble Setting this object is
implementation specific for Frame Relay
logical ports.
ifHighSpeed Set to the user data rate of the frame
relay logical port in millions of
bits per second. If the user data rate
is less than 1 Mbps, then this value is zero.
ifPromiscuousMode Set to false(2).
Frame Relay Network Service interfaces do not support any
other groups or objects in the Interfaces group of MIB II.
Also, using the SNMP Group of MIB II is an implementation
choice.
