1. The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC2571 [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, RFC1155 [2], STD 16, RFC1212 [3] and RFC1215 [4]. The
second version, called SMIv2, is described in STD 58, RFC2578
[5], STD 58, RFC2579 [6] and STD 58, RFC2580 [7].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC1157 [8]. A second version of the SNMP
message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC1901 [9] and RFC
1906 [10]. The third version of the message protocol is called
SNMPv3 and described in RFC1906 [10], RFC2572 [11] and RFC2574
[12].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC1157 [8]. A second set of protocol
operations and associated PDU formats is described in RFC1905
[13].
o A set of fundamental applications described in RFC2573 [14] and
the view-based access control mechanism described in RFC2575
[15].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC2570 [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
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.
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 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 Interface MIB 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.
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 1 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.
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 DS1 line, an access channel can denote any one of the
following:
o Unchannelized DS1 - the entire DS1 line is considered an access
channel. Each access channel is comprised of 24 DS0 time slots.
o Channelized DS1 - an access channel is any one of 24 channels.
Each access channel is comprised of a single DS0 time slot.
o Fractional DS1 - an access channel is a grouping of NxDS0 time
slots (NX56/64 Kbps, where N = 1-23 DS0 Time slots per Fractional
DS1 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 E1 (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
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 (DS0) - An octet within the 192-bit information field in
each DS1 frame is defined as a time slot. Time slots are position
sensitive within the 192-bit information field. Fractional DS1
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
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 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 equipment (e.g., switches, routers or
networks) supporting frame relay. 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.
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
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
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 notifications be
disabled since both are not required.
Notifications are enabled at the frame relay
service layer specifically because PVC
notifications are not to be sent if the frame
relay interface fails. Without a
linkUp/linkDown notification, 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.
+---------------------+
Frame Relay Service
+---------------------+
+---------------------+
ds0Bundle
+---------------------+
+---+ +---+ +---+ +---+
ds0 ds0 ds0 ds0
+---+ +---+ +---+ +---+
+---------------------+
ds1
+---------------------+
The assignment of the index values could for example be:
ifIndex Description
1 FrameRelayService (type 44)
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.
ifStackTable Entries

1 2
2 3
2 4
2 5
2 6
3 7
4 7
5 7

7 0
In the case where the frame relay service is using a single ds0, then
the ds0Bundle is not required.
+---------------------+
Frame Relay Service
+---------------------+
+---+
ds0
+---+
+---------------------+
ds1
+---------------------+
The assignment of the index values could for example be:
ifIndex Description
1 FrameRelayService (type 44)
2 ds0 (type 81)
3 ds1 (type 18)
The ifStackTable is then used to show the relationships between the
various interfaces.
ifStackTable Entries
HigherLayer LowerLayer

2.5.4. Stack Table for V.35 Environments
This section describes by example how to use ifStackTable to
represent the relationship of frame relay service with V.35
interfaces.
+---------------------+
Frame Relay Service
+---------------------+
+---------------------+
v35
+---------------------+
An example of index values in this case could be:
ifIndex Description
1 FrameRelayService (type 44)
2 v35 (type 33)
Note type 33 (RS232-like MIB) is used instead of type 45 (V.35). V35
does not pertain to this environment.
The ifStackTable is then used to show the relationships between the
various interfaces.
ifStackTable Entries
HigherLayer LowerLayer
0 1
1 2
2 0
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. The
frPVCEndptConnectIdentifier object of each endpoint points to the
frPVCConnectTable cross-connect table row for the connection.
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].
In the case of an inter-worked connection, the
frPVCEndptConnectIdentifier object is set to zero. Instead, the
frPVCEndptAtmIwfConnIndex object is set to the index of the FR/ATM
IWF cross-connect table row.
The frame relay PVC cross-connect table (frPVCConnectTable) does not
contain an entry for the FR/ATM inter-worked connection.
2.6. Textual Convention Change
Version 1 of the Frame Relay Service MIB contains MIB objects defined
with the 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 new TC provides
support for a greater variety of international character sets.
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.

DESCRIPTION
"The value of this object is used as a pointer to

This object has been deprecated to reflect the
fact that the local in-channel signaling
parameters are accessed from a single table
(frMgtVCSigTable) that includes parameters for all
possible signaling protocols. Early design
anticipated multiple tables, one for each

matches the SYNTAX of the frPVCEndptDLCIIndex - an
object that is restricted to legal Q.922 DLCI
values for the size of the address field.
The value 0 indicates that no unassigned entries
are available.
To oBTain the frPVCEndptDLCIIndex value for a new
entry, the manager issues a management protocol
retrieval operation to obtain the current value of
this object. After each retrieval, the agent must
modify the value to the next unassigned index to
prevent assignment of the same value to multiple
management systems.
A management system should repeat the read to
obtain a new value should an attempt to create the
new row using the previously returned hint fail."

DESCRIPTION
"The Frame Relay PVC End-Point table. This table
is used to model a PVC end-point. This table
contains the traffic parameters and statistics for
a PVC end-point.
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 figure 2, 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
Endpoint.
