frPVCConnectTable OBJECT-TYPE
SYNTAX SEQUENCE OF FrPVCConnectEntry
MAX-ACCESS not-accessible
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.

__________________________________

_____| >> from low to high PVC flow >> |_____

|__________________________________|
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."

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.7.

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 VC Objects frMgtVCSigProcedAdmin frMgtVCSigUserN391Admin frMgtVCSigUserN392Admin frMgtVCSigUserN393Admin frMgtVCSigUserT391Admin frMgtVCSigNetN392Admin frMgtVCSigNetN393Admin frMgtVCSigNetT392Admin frMgtVCSigNetnT3Admin (3) Add objects to control fragmentation: 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 frPVCEndptInFramesFECNSet frPVCEndptOutFramesFECNSet frPVCEndptInFramesBECNSet frPVCEndptOutFramesBECNSet frPVCEndptInCongDiscards frPVCEndptInDECongDiscards frPVCEndptOutCongDiscards frPVCEndptOutDECongDiscards frPVCEndptOutDEFrames (5) Added the PVC object frPVCEndptAtmIwfConnIndex to identify the type of connection, frame relay or ATM IWF; and to identify the cross-connect row of the FR/ATM IWF MIB.
(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.
(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
frMgtVCSigNetnN4
frMgtVCSigNetnT3
frMgtVCSigUserLinkRelErrors
frMgtVCSigUserProtErrors
frMgtVCSigUserChanInactive
(14) DESCRIPTION text addressing case of logical port not performing
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.
(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.
