            STATUS      current
            DESCRIPTION
                    "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.

                    4)  Set frPVCConnectAdminStatus to `active(1)' in

                        all rows for this PVC segment to turn the
                        PVC on.

                    For example, the Frame Relay PVC Connection Group
                    models a bi-directional, point-to-point PVC
                    segment as one entry in this table.

                            |__________________________________|

                    The terms low and high are chosen to represent
                    numerical ordering of a PVC segment's endpoints
                    for representation in this table.  That is, the
                    endpoint with the lower value of ifIndex is termed
                    'low', while the opposite endpoint of the segment
                    is termed 'high'.  This terminology is to provide
                    directional information; for example the
                    frPVCConnectL2hOperStatus and
                    frPVCConnectH2lOperStatus as illustrated above.

                    If the Frame Relay Connection table is used to
                    model a unidirectional PVC, then one direction
                    (either from low to high or from high to low) has
                     its Operational Status equal to down.

                     A PVC segment is a portion of a PVC that traverses
                    one Frame Relay Network, and a PVC segment is
                    identified by its two end-points (UNI/NNI logical
                    port index value and DLCI index value) through one
                    Frame Relay Network."

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.

Top      Up      ToC       Page 70 
   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

   (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:

   (8)  Updated compliance modules and object groups to reflect the new
        objects and notification:

        frnetservCompliance2 -      New service-centric (read-only)

        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.

Top      Up      ToC       Page 73 
   (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
        frMgtVCSigNetN393
        frMgtVCSigNetT391
        frMgtVCSigNetN392

        network-side procedures was removed from following objects:

        frMgtVCSigNetLinkRelErrors
        frMgtVCSigNetChanInactive
        frMgtVCSigNetProtErrors

   (15) frPVCEndptConnectIdentifier - Operation described for the case
        of FR/ATM IWF cross-connect operation.

   (16) frPVCEndptRcvdSigStatus - Added description of enumerated
        values.

   (17) frPVCEndptInDiscards - Clarified DESCRIPTION to state that
        congestion discards are not counted by object.

   (18) frPVCConnect{Low|High}IfIndex - Changed to use InterfaceIndex TC
        and changed reference to MIB-II to the new IF-MIB.  Removed
        statement asserting that a zero value means the port is not a FR
        logical port.

Top      Up      ToC       Page 74 
   (19) frPVCConnectIndex - Added a range to the SYNTAX clause

   (20) frPVCConnect{L2h|H2l}OperStatus - Added DESCRIPTION text for
        each enumerated value.

   (21) frAccountPVCDLCIIndex - Added a range to the SYNTAX clause

   (22) frPVCCOnnectStatusChange Notification - STATUS change to
        deprecated.  Obsoleted to eliminate inappropriate inclusion of
        index objects

   (23) frPVCConnectStatusNotif Notification - Replaces
        frPVCConnectStatusChange.  In addition, the notification now
        requires 2 instances of the frPVCEndptRcvdSigStatus object, one
        for each endpoint of the connection.

   (24) Guidance added to recommend ifLinkUpDownTrapEnable be set on.

   (25) Behavior of the PVC status and endpoint signaling status is
        clarified for the case of underlying layer failure.

   (26) Overview text re-written for clarity.

   (27) Clarified role of system group.

   (28) Established maximum frame size of 4096 and default value of
        1600.

   (29) Clarified that DLC index range is restricted to valid range for
        the specific length of address field used on the logical port.

   (30) Figure 1 and accompanying text was removed to eliminate a
        confusing "MIB stack" concept.  See the section titled "Relation
        to Other MIBs" for replacement text.
