How to discovery IS-IS Adjacency Groups from Nokia 7750 SR?

[wyang]

Nokia 7750 SR supports multiple instances of IS-IS. We need to monitor the status of adjacency groups of IS-IS instances. The status of each adjacency can be derived from the IS-IS adjacency table in the IS-IS MIB, where each OID has three levels of indices: IS-IS instance index, circuit index and adjacency index.

How to set up a discovery rule or discovery rules to discover each IS-IS adjacency?


IS-IS adjacency table in the IS-IS MIB:

isisISAdjTable OBJECT-TYPE
SYNTAX SEQUENCE OF IsisISAdjEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The table of adjacencies to Intermediate Systems."
::= { isisISAdj 1 }

isisISAdjEntry OBJECT-TYPE
SYNTAX IsisISAdjEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Each entry corresponds to one adjacency to an
Intermediate System on this system."
INDEX { isisSysInstance,
isisCircIndex,
isisISAdjIndex }
::= { isisISAdjTable 1 }


Any advice would be much appreciated.

Example of snmpwalk results showing 3 levels of indices

$ snmpwalk -v2c -cplebeian 10.200.1.10 ISIS-MIB::isisSysType
ISIS-MIB::isisSysType.0 = INTEGER: level2IS(2)
ISIS-MIB::isisSysType.2 = INTEGER: level2IS(2)

$ snmpwalk -v2c -cplebeian 10.200.1.10 ISIS-MIB::isisCircType
ISIS-MIB::isisCircType.0.1 = INTEGER: ptToPt(2)
ISIS-MIB::isisCircType.0.25 = INTEGER: ptToPt(2)
ISIS-MIB::isisCircType.0.26 = INTEGER: ptToPt(2)
ISIS-MIB::isisCircType.2.4 = INTEGER: ptToPt(2)
ISIS-MIB::isisCircType.2.7 = INTEGER: ptToPt(2)
ISIS-MIB::isisCircType.2.12 = INTEGER: ptToPt(2)
ISIS-MIB::isisCircType.2.19 = INTEGER: ptToPt(2)

$ snmpwalk -v2c -cplebeian 10.200.1.10 ISIS-MIB::isisISAdjState
ISIS-MIB::isisISAdjState.0.25.1 = INTEGER: up(2)
ISIS-MIB::isisISAdjState.0.26.1 = INTEGER: up(2)
ISIS-MIB::isisISAdjState.2.19.1 = INTEGER: up(2)
