1. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [1].
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in
STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
second version, called SMIv2, is described in STD 58, RFC 2578
[5], RFC 2579 [6] and RFC 2580 [7].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [8]. A second version of the SNMP
message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [9] and
RFC 1906 [10]. The third version of the message protocol is
called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and
RFC 2574 [12].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[13].
o A set of fundamental applications described in RFC 2573 [14] and
the view-based access control mechanism described in RFC 2575
[15].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [16].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the mechanisms defined in the SMI.
This memo specifies a MIB module that is compliant to the SMIv2. A
MIB conforming to the SMIv1 can be produced through the appropriate
translations. The resulting translated MIB must be semantically
equivalent, except where objects or events are omitted because no
translation is possible (use of Counter64). Some machine readable
Expires April 2000 [Page 4]
Internet Draft Frame Relay Service MIB October 1999
information in SMIv2 will be converted into textual descriptions in
SMIv1 during the translation process. However, this loss of machine
readable information is not considered to change the semantics of the
MIB.

2. Overview
These objects are used to manage a frame relay Service. At present,
this applies to the following value of the ifType variable in the
IF-MIB [26]:
frameRelayService (44)
This section provides an overview and background of how to use this
MIB and other potential MIBs to manage 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.

Figure 1. Frame Relay MIB Architecture
2.1. Scope of MIB
The Frame Relay Service MIB supports Customer Network Management (CNM)
of a frame relay network service. Through the use of this and other
related MIBs, a frame relay service customer's NMS can monitor the
customer's UNI/NNI logical ports and PVCs. It provides customers with
access to configuration data, performance monitoring information, and
Expires April 2000 [Page 6]
Internet Draft Frame Relay Service MIB October 1999
fault detection for the delivered frame relay service. As an option, an
SNMP agent supporting the Frame Relay Service MIB may allow customer-
initiated PVC management operations such as creation, deletion,
modification, activation, and deactivation of individual PVCs. However,
internal aspects of the network (e.g., switching elements, line cards,
and network routing tables) are beyond the scope of this MIB.
The Frame Relay Service MIB models all interfaces and PVCs delivered by
a frame relay service within a single virtual SNMP system for the
purpose of comprehensively representing the customer's frame relay
service. The customer's interfaces and PVCs may physically exist on one
or more devices within the network topology. An SNMP agent providing
support for the Frame Relay Service MIB as well as other appropriate
MIBs to model a single virtual frame relay network service is referred
to as a Frame Relay Service (FRS) agent. Internal communication
mechanisms between the FRS agent and individual devices within the frame
relay network delivering the service are implementation specific and
beyond the scope of this MIB.
The customer's NMS will typically access the SNMP agent implementing the
Frame Relay Service MIB over a frame relay permanent virtual connection
(PVC). SNMP access over a frame relay PVC is achieved through the use
of SNMP over UDP over IP encapsulated in Frame Relay according to STD
55, RFC2427 and ITU X.36 Annex D [23]. Alternate access mechanisms and
SNMP agent implementations are possible.
This MIB will NOT be implemented on user equipment (e.g., DTE). Such
devices are managed using the Frame Relay DTE MIB (RFC2115[18]).
However, concentrators may use the Frame Relay Service MIB instead of
the Frame Relay DTE MIB.
This MIB does not define managed objects for the physical layer.
Existing physical layer MIBs (e.g., DS1 MIB) and MIB II will be used as
needed in FRS Agent implementations.
This MIB supports frame relay PVCs. This MIB may be extended at a later
time to handle frame relay SVCs.
Expires April 2000 [Page 7]
Internet Draft Frame Relay Service MIB October 1999
A switch implementation may support this MIB for the purpose of
configuration and control of the frame relay service beyond the scope of
traditional customer network management applications. A number of
objects (e.g. frLportTypeAdmin) support administrative actions that
impact the operation of frame relay switch equipment in the network.
This is reflected in the differences between the two MIB compliance
modules:
o the frame relay service compliance module (frnetservCompliance),
and
o the frame relay switch compliance module
(frnetSwitchCompliance).
The frame relay service compliance module does not support the
administrative control objects used for switch management.
2.2. Transiting Multiple Frame Relay Networks
This MIB is only used to manage a single frame relay service offering
from one network service provider. Therefore, if a customer PVC
traverses multiple networks, then the customer must poll a different FRS
agent within each frame relay network to retrieve the end-to-end view of
service.
Figure 2 illustrates a customer ("User B") NMS accessing FRS agents in
three different frame relay networks (I, J, and K).

2.3. Access Control
A frame relay network is shared amongst many frame relay subscribers.
Each subscriber will only have access to their information (e.g.,
information with respect to their interfaces and PVCs). The FRS agent
SHOULD provide instance level granularity for MIB views.
Expires April 2000 [Page 9]
Internet Draft Frame Relay Service MIB October 1999
2.4. 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), and unframed Ei (G.703 without G.704).
Access Rate - The data rate of the access channel, expressed in
bits/second. 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
subscriber data (expressed in bits) that the network agrees to
Expires April 2000 [Page 10]
Internet Draft Frame Relay Service MIB October 1999
transfer, under normal conditions, during a time interval Tc.
Be - The Excess Burst Size (Be) is the maximum amount of subscriber
data (expressed in bits) in excess of Bc that the network will
attempt to deliver during the time interval Tc. This data (Be) is
delivered in general with a lower probability than Bc.
CIR - The Committed Information Rate (CIR) is the subscriber data
rate (expressed in bits/second) that the network commits to deliver
under normal network conditions. CIR is averaged over the time
interval Tc (CIR = Bc/Tc).
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
T391 - Link integrity verification polling timer
T392 - Polling verification timer
nT3 - Status enquiry timer
Expires April 2000 [Page 11]
Internet Draft Frame Relay Service MIB October 1999
nN3 - Maximum status enquiry counter
2.5. Relation to Other MIBs
2.5.1. System Group
Use the System Group of the SNMPv2-MIB [27] to describe the Frame
Relay Service (FRS) agent. The FRS agent may be monitoring many
frame relay devices in one network. The System Group does not
describe frame relay devices monitored by the FRS agent.
sysDescr: ASCII string describing the FRS 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
FRS agent.
sysUpTime: Clock in the FRS agent; TimeTicks
in 1/100s of a second. Elapsed type since
the FRS agent came on line.
sysContact: Contact for the FRS agent.
ASCII string of up to 255 characters.
sysName: Domain name of the FRS agent, for example,
acme.com
sysLocation: Location of the FRS 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.
2.5.2. Interfaces Table (ifTable, ifXtable)
This specifies how the Interfaces Group defined in the IF MIB [26] 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 evolution of the Interfaces group to be in
Expires April 2000 [Page 12]
Internet Draft Frame Relay Service MIB October 1999
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 and
1,984,000 bits per second for an E1-based
UNI/NNI logical port.
Expires April 2000 [Page 13]
Internet Draft Frame Relay Service MIB October 1999
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 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 value of sysUptime at 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.
Specifically, frames discarded due to ingress
buffer congestion and traffic policing.
ifInErrors The number of received frames that are
discarded because of an error. Specifically,
frames that are too long or too short, frames
that are not a multiple of 8 bits in length,
frames with an invalid or unrecognized DLCI,
frames with an abort sequence, frames with
improper flag delimitation, and frame that
fail FCS.
ifInUnknownProtos The number of packets discarded because of an
unknown or unsupported protocol. For Frame
Relay Service interfaces, this counter will
Expires April 2000 [Page 14]
Internet Draft Frame Relay Service MIB October 1999
always be zero.
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 unerrored, unicast frames sent.
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 an error. Specifically,
frames that are aborted due to a transmitter
underrun.
ifName This variable is not applicable for Frame
Relay Service interfaces, therefore, this
variable contains a zero-length string.
ifInMulticastPkts The number of received unerrored, multicast
frames.
ifInBroadcastPkts This variable is not applicable for Frame
Relay Service interfaces, therefore, this
counter is always zero.
ifOutMulticastPkts The number of sent unerrored, multicast
frames.
ifOutBroadcastPkts This variable is not applicable for Frame
Relay Service interfaces, therefore, this
counter is always zero.
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.
ifHCOutOctets Only used for DS3-based (and greater) Frame
Relay logical ports. The number of
transmitted octets. This counter only counts
Expires April 2000 [Page 15]
Internet Draft Frame Relay Service MIB October 1999
octets from the beginning of the frame relay
header field to the end of user data.
ifLinkUpDownTrapEnable Set to true(1). It is recommended that the
underlying physical layer traps be disabled
since both are not required. Traps are
enabled at the frame relay service layer
specifically because PVC traps are not to be
sent if the frame relay interface fails.
Without a linkUp/linkDown trap, the
management station would receive no
notification of the failure.
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).
ifConnectorPresent Set to false(2).
Frame relay network service interfaces support the Interface Stack
Group. Frame relay network service interfaces do not support any other
groups or objects in the Interfaces group of the IF MIB.

2.5.3. Stack Table for DS1/E1 Environment This section describes by
example how to use ifStackTable to represent the relationship of frame
relay service to ds0 and ds0Bundles with ds1 interfaces. [20]
Example: A frame relay service is being carried on 4 ds0s of a ds1.

The assignment of the index values could for example be:

2 ds0Bundle (type 82)
3 ds0 #1 (type 81)
4 ds0 #2 (type 81)
5 ds0 #3 (type 81)
6 ds0 #4 (type 81)
7 ds1 (type 18)
The ifStackTable is then used to show the relationships between the
various interfaces.

2.5.5. The Frame Relay/ATM PVC Service Interworking MIB
Connections between two frame relay endpoints are represented with an
entry in the frPVCConnectTable of this MIB. Both endpoints are
represented with rows in the frPVCEndptTable.
In contrast, a connection that spans frame relay and ATM endpoints is
represented with an entry in the frAtmIwfConnectionTable of the
FR/ATM PVC Service Interworking MIB defined in [28].
The object frPVCEndptConnKind identifies the type of connection and
thus the applicable cross-connection table.
The object frPVCEndptConnectIdentifier contains a value used as an
index into the applicable cross-connection table. In the case of the
frPVCConnectTable the value is applied with the frPVCConnectIndex
object. In the case of the frAtmIwfConnectionTable the value is

Internet Draft Frame Relay Service MIB October 1999
applied with the frAtmIwfConnIndex object.
2.6. Textual Convention Change
Version 1 of the Frame Relay Service MIB contains MIB objects defined
with the (now obsolete) DisplayString textual convention. In version 2
of this MIB, the syntax for these objects has been updated to use the
(now preferred) SnmpAdminString textual convention.
The working group realizes that this change is not strictly supported by
SMIv2. In our judgment, the alternative of deprecating the old objects
and defining new objects would have a more adverse impact on backward
compatibility and interoperability, given the particular semantics of
these objects.

-- The PVC End-Point Group
-- This table is used to identify the traffic parameters
-- for a bi-directional PVC segment end-point, and it also
-- provides statistics for a PVC segment
-- end-point.
-- A PVC segment end-point is identified by a UNI/NNI
-- logical port index value and DLCI index value.
-- If the frame relay service provider allows
-- the frame relay CNM subscriber to create, modify
-- or delete PVCs using SNMP, then this table is used
-- to identify and reserve
-- the requested traffic parameters of each
-- PVC segment end-point. The Connection table
-- is used to "connect" the end-points together.
-- Not all implementations will support the
-- capability of creating/modifying/deleting
-- PVCs using SNMP as a feature of frame relay
-- CNM service.
-- Uni-directional PVCs are modeled with zero
-- valued traffic parameters in one of the
-- directions (In or Out direction) in this table.
-- To create a PVC, the following procedures
-- shall be followed:
-- 1). Create the entries for the PVC segment endpoints in the
-- frPVCEndptTable by specifying the traffic parameters
-- for the bi-directional PVC segment endpoints.
-- As shown in the figure, a point-to-point PVC has
-- two endpoints, thus two entries in this table.
-- Uni-directional PVCs are modeled
-- with zero valued traffic parameters in one
-- direction; all the `In' direction parameters
-- for one frame relay PVC End-point or
-- all the `Out' direction
-- parameters for the other frame relay PVC
-- End-point.

6. Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
No managed objects in this MIB contain sensitive information.
SNMPv1 by itself is not a secure environment. Even if the network
itself is secure (for example by using IPSec), even then, there is no
control as to who on the secure network is allowed to access and
GET/SET (read/change/create/delete) the objects in this MIB.
It is recommended that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the use
of the User-based Security Model RFC 2574 [12] and the View-based
Access Control Model RFC 2575 [15] is recommended.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, is properly
configured to give access to the objects only to those principals
(users) that have legitimate rights to indeed GET or SET
(change/create/delete) them.

APPENDIX A Update Information
The changes from RFC 1604 are the following:
(1) This MIB works for switches too. Read-writable
versions of a number of frLport and frVCSig objects
were created to allow this.
(2) frPVCEndptInDiscards was clarified. Congestion
discards are not counted.
(3) Descriptions were added for the values of
frPVCEndptRcvdSigStatus.
(4) An additional instance of frPVCEndptRcvdSigStatus was
added to the Connect Status Change Trap. There is now
one for each endpoint.
(5) ifLinkUpDownTrapEnable is now recommended to be on.
(6) frVCSigProced was slightly unclear. The values are
clarified along with associated counter definitions.
(7) The behaviour of the PVC statuses and the Endpt Sig
Statuses are clarified when an underlying layer fails.
(8) frPVCConnectIndexValue was added.
(9) An ifStackTable example was added.
(10) Additional counters for PVCs were added.
(11) Names for PVCs were added.
(12) Addition of counters to track frames offered (in)
and delivered (out) for increased visibility into
policing-driven discards, congestion-driven discards,
DE bit setting, and congestion bit setting.

(13) Addition of Frame Relay Fragmentation objects
frLportFragControl and frLportFragSize.
(14) Reference to RFC 1490 changed to STD 55, RFC 2427.
(15) Created a NOTIFICATION object identified using the
trap prefix convention to support automatic generation
of SMIv1 MIB. The new object is named
frPVCConnectStatusNotif. The old object
frPVCConnectStatusChange has been obsoleted. The
compliance statements have been obsoleted/created
to match.
(16) Add frPVCEndptConnKind object to select FR/ATM Service
IWF as a target for an interworked connection.
