+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], STD 58, RFC 2579 [6] and STD 58, 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].
+
+
+
+
+
+Rehbehn & Fowler Standards Track [Page 2]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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
+ 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
+
+
+
+Rehbehn & Fowler Standards Track [Page 3]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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.

+RFC 2954 Frame Relay Service MIB October 2000
+
+
+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.
+
+
+
+
+
+Rehbehn & Fowler Standards Track [Page 6]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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:
+
+
+
+
+
+Rehbehn & Fowler Standards Track [Page 8]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ - 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.
+
+
+
+
+
+
+Rehbehn & Fowler Standards Track [Page 9]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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.
+
+
+
+Rehbehn & Fowler Standards Track [Page 10]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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.

+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.
+
+
+
+Rehbehn & Fowler Standards Track [Page 14]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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.

+ "The Frame Relay PVC End-Point table. This table

+

+
+ 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.

+ "The Frame Relay PVC Connect Table is used to
+ model the bi-directional PVC segment flows
+ including: point-to-point PVCs, point-to-
+ multipoint PVCs, and multipoint-to-multipoint
+ PVCs.
+
+ This table has read-create access and is used to
+ associate PVC end-points together as belonging to
+ one connection. The frPVCConnectIndex is used to
+ associate all the bi-directional flows. Not all
+ implementations will support the capability of
+ creating/modifying/deleting PVCs using SNMP as a
+ feature of frame relay CNM service.
+
+ Once the entries in the frPVCEndptTable are
+ created, the following step are used to associate
+ the PVC end-points as belonging to one PVC
+ connection:
+
+ 1) Obtain a unique frPVCConnectIndex
+ using the frPVCConnectIndexValue object.
+
+ 2) Connect the PVC segment endpoints together
+ with the applicable frPVCConnectIndex value
+ obtained via frPVCConnectIndexValue. The
+ entries in this table are created by using
+ the frPVCConnectRowStatus object.
+
+ 3) The agent will provide the value of the
+ corresponding instances of
+ frPVCEndptConnectIdentifier with the
+ frPVCConnectIndex value.

+
+ If the Frame Relay Connection table is used to

+
+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.
+
+
+
+
+
+
+
+Rehbehn & Fowler Standards Track [Page 69]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ 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) Added the object frLportDLCIIndexValue to automatically generate
+ index values for new DLC rows.
+
+ (2) Add the following objects to support manager writing to objects:
+
+ Logical Port Objects
+ frLportTypeAdmin
+ frLportVCSigProtocolAdmin
+

+
+ frLportFragControl frLportFragSize
+
+ (4) Added objects to track frames offered to network (in) and
+ delivered (out) for increased visibility into policing-driven
+ discards, congestion-driven discards, DE-bit setting, and
+ congestion bit setting:
+
+ frPVCEndptInDiscardsDESet

+ cross-connect row of the FR/ATM IWF MIB.
+
+
+
+
+Rehbehn & Fowler Standards Track [Page 71]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ (6) Added objects to provide printable names of the connection user
+ and service provider:
+
+ frPVCConnectUserName
+ frPVCConnectProviderName
+
+ (7) Added a new notification to correct flaws in the RFC1604 trap.
+ The flaws include improper OID suffix (SMIv1 compatibility
+ issue) and the inclusion of redundant index fields
+
+ (8) Updated compliance modules and object groups to reflect the new
+ objects and notification:
+
+ frnetservCompliance2 - New service-centric (read-only)
+ compliance module
+
+ frnetSwitchCompliance - New switch-centric (read-write)
+ compliance module
+
+ frnetservCompliance - Original RFC 1604 Module, now
+ deprecated
+
+ frnetservLportGroup - Original RFC 1604 logical port
+ group, now deprecated
+
+ frnetservLportGroup2 - Replacement logical port group
+
+ frnetservPVCEndptGroup2 - Extension objects with this
+ revision of the MIB
+
+ frnetservPVCConnectNamesGroup - New group w/ display names
+ for connections
+
+ frnetservLportAdminGroup - New group w/ read-write objects
+ for the logical port
+
+ frnetservMgtVCSigAdminGroup - New group w/ read-write objects
+ for the signaling protocol
+
+ frnetservPVCNotifGroup - Group deprecated to eliminate
+ obsolete frPVCConnectStatusChange
+ notification
+
+ frnetservPVCNotifGroup2 - New group added with w/
+ frPVCConnectStatusNotif
+
+ (9) Added UNITS and REFERENCE clauses for objects that needed the
+ clarification.
+
+
+
+Rehbehn & Fowler Standards Track [Page 72]
+
+RFC 2954 Frame Relay Service MIB October 2000
+
+
+ (10) Changed references to "proxy-agent" to "FRS agent" to avoid
+ confusion with other proxy-agent terminology.
+
+ (11) Changed objects using the DisplayString TC to use the
+ SnmpAdminString TC.
+
+ (12) frMgtVCSigProced - Expanded to include the u2nuser(3)
+ enumeration for the UNI protocol operation where the logical
+ port operates in the user role.
+
+ (13) DESCRIPTION text added to specify agent response when object is
+ not instantiated for the following objects:
+
+ frMgtVCSigUserN391
+ frMgtVCSigUserN393
+ frMgtVCSigUserT391
+ frMgtVCSigUserN392
+ frMgtVCSigNetN391
