connPvcTable OBJECT-TYPE
SYNTAX SEQUENCE OF ConnPvcEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"The table containing information on current PVC/SVCs.
Currently, only PVCs are represented in this table.
The table is also used to establish and delete PVCs.
1. PVC establishment procedure
(1) Read connPvcIndexNext. This value is used as the value of connPvcIndex for the new connection.
(2) Determine the value of connPvcHighIfIndex. When creating a new point-to-multipoint connection, connPvcHighIfIndex must identify the first leaf.
When creating a new point-to-point connection, connPvcHighIfIndex normally identifies the interface with the higher value of ifIndex.
(3) Set connPvcRowStatus to 'createAndWait' using the values of connPvcIndex and connPvcHighIfIndex as indexes.
This causes the switch to create the new row with some objects being set to default values. The parameters for which there is no reasonable default are set to 0xffffffff.
Object Default
connPvcTopology bidirectionalVCC(2)
connPvcTrafficType trafficUBR(4)
connPvcLowIfIndex 0xffffffff
connPvcLowVPI 0xffffffff
connPvcLowVCI 0xffffffff
connPvcLowUpcParam 512
connPvcLowUpc pass(1)
connPvcLowThroughput 0
connPvcHighVPI 0xffffffff
connPvcHighVCI 0xffffffff
connPvcHighUpcParam 512
connPvcHighUpc pass(1)
connPvcHighThroughput 0
The switch then sets the value of connPvcRowStatus to 'notReady'. The default values can be read by the NMS.
(4) The values of the above objects which are set to 0xffffffff must be modified, and the values of any other objects can be changed. When establishing a VP connection, connPvcLowVCI and connPvcHighVCI should be set to 0.
When all parameters have acceptable values, the switch sets connPvcRowStatus to 'notInService'.
(5) When the NMS sets connPvcRowStatus to 'active', the switch validates each parameter's value, and tries to establish the connection. If this operation fails, the the cause of the failure is indicated by the value of connPvcCause.
2. Adding a new leaf to an existing pt-to-mpt connection
(1) Determine the value of connPvcIndex for the existing point-to-multipoint connection to which a new leaf is to be added.
(2) Determine the value of connPvcHighIfIndex as the ifIndex value of the interface to be used for the new leaf.
(3) Set connPvcRowStatus to 'createAndWait' using the values of connPvcIndex and connPvcHighIfIndex as indexes.
This causes the switch to create the new leaf with some objects being set to default values. The parameters for which there is no reasonable default are set to 0xffffffff.
Object Default
connPvcHighVPI 0xffffffff
connPvcHighVCI 0xffffffff
connPvcHighUpcParam 512
connPvcHighUpc pass(1)
connPvcHighThroughput 0
The switch then sets the value of connPvcRowStatus to 'notReady'. The default values can be read by the NMS.
(4) The NMS must modify the values of connPvcHighVPI and connPvcHighVCI, and can modify the values of connPvcHighUpc,
connPvcHighUpcParam and connPvcHighThroughput. When establishing a VP connection, connPvcHighVCI should be set to 0. The NMS should not change the values of the following objects:
connPvcTopology
connPvcTrafficType
connPvcLowIfIndex
connPvcLowVPI
connPvcLowVCI
connPvcLowUpcParam
connPvcLowUpc
connPvcLowThroughput
When all parameters have acceptable values, the switch sets connPvcRowStatus to 'notInService'.
(5) When the NMS sets connPvcRowStatus to 'active', the switch validates each parameter's value, and tries to add the new leaf to the original connection. If this operation fails, the cause of the failure is indicated by the value of connPvcCause.
3. PVC deletion procedure
(1) Set the connPvcRowStatus to 'destroy'.
If the row exists but is impossible to delete, the cause of the failure is indicated by the value of connPvcCause.
If the deletion is successful, the row is deleted (including the instance of connPvcCause for that row).
Note: a row representing a connection between the gateway-PAD (the switch's internal port) and a line interface will not have instances of the following objects: connPvcLowUpc, connPvcLowUpcParam, connPvcLowThroughput, connPvcHighUpc, connPvcHighUpcParam, connPvcHighThroughput, connPvcHighOutCells, connPvcHighInCells, and connPvcHighUpcViolatedCells."
