The SNMPv2 Network Management Framework consists of four major components. They are:
The Framework permits new objects to be defined for the purpose of experimentation and evaluation.
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.
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.

Figure 1. Frame Relay MIB Architecture
The Frame Relay Service MIB will only manage the Frame Relay portion of the network. This MIB is based upon the Customer Network Management concepts presented in the document "Service Management Architecture for Virtual Connection Services" [6].
This MIB will NOT be implemented on User Equipment (e.g., DTE), and the Frame Relay DTE MIB (RFC 1315) should be used to manage those devices [8].
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. It is an implementation decision as to whether this MIB is used to create/delete/modify PVCs and to turn PVCs on or off.
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 typically 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 [7,9]. The customer, thus,
has a PVC to the SNMP proxy-agent. Alternate access mechanisms and SNMP agent implementations 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. This MIB will typically be implemented on a service provider's SNMP proxy-agent. The SNMP proxy-agent proxies for all Frame Relay equipment within one service provider's Frame Relay network. (Other SNMP agent implementations are not precluded.) 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 within each Frame Relay Network to retrieve their end-to-end view of their service. See Figure 2 and the Service Management Architecture [6].

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.
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:
Within a given E1 line, a channel can denote any one of the following:
in 3 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, 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 (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
nN3 - Maximum status enquiry counter
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 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 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 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.
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 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 errors.
Possible reason is transmit underruns.
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.
ifLinkUpDownTrapEnble The value of 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).
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 MIB II. Also, supporting the SNMP Group of MIB II is an implementation choice.
