ISIS adjacency monitoring under IOS-XR 4.3.1

[scorpion]

Hi,

I need to monitor my entire networks ISIS adjancencies using SNMP Trap. But I am having some hard time figuring out the OID values. Can someone please help me figure out the OID's required for ISIS adjacency monitoring.

HW : Cisco 12416

SW : IOS XR 4.3.1

Thanks in advance.

Ensure you have the isis traps you want enabled:

RP/0/8/CPU0:PR-GSR-1(config)#snmp-server traps isis ?

  adjacency-change                isisAdjacencyChange

  all                             Enable all IS-IS traps

  area-mismatch                   isisAreaMismatch

  attempt-to-exceed-max-sequence  isisAttemptToExceedMaxSequence

  authentication-failure          isisAuthenticationFailure

  authentication-type-failure     isisAuthenticationTypeFailure

  corrupted-lsp-detected          isisCorruptedLSPDetected

  database-overload               isisDatabaseOverload

  id-len-mismatch                 isisIDLenMismatch

  lsp-error-detected              isisLSPErrorDetected

  lsp-too-large-to-propagate      isisLSPTooLargeToPropagate

You can view the supported MIB's per XR12K release here:

ftp://ftp.cisco.com/pub/mibs/supportlists/xr12000/xr12000-supportlist.html

We support the ISIS-MIB

ftp://ftp.cisco.com/pub/mibs/v2/ISIS-MIB.my

Refer to the isis adjacency table info:

-- The IS Adjacency Table
--
-- Each adjacency to an IS corresponds to one entry in this
-- table.

    isisISAdjTable OBJECT-TYPE

Full RFC4444 ISIS MIB support was added from 4.1.0 onwards. Prior to that it was partailly supported

You can map the OID's from the router to above ISIS-MIB.my file via CLI:

Hi,

Thanks for your reply.

show snmp mib object-name | inc ISAdj did the trick for me.

Happy networking.
