ISIS_1.3.6.1.3.37.2.0.16 isisProtocolsSupportedMismatch

Trap Buffer Description

The protocol of received Protocol TLV is mismatched with local configuration. (isisSysInstance=[isisSysInstance], isisSysLevelIndex=[isisSysLevelIndex], isisCircIndex=[isisCircIndex], isisCircIfIndex=[isisCircIfIndex], isisPduProtocolsSupported=[isisPduProtocolsSupported], isisPduLspId=[isisPduLspId], isisPduFragment=[isisPduFragment], ifIndex=[ifIndex], IfName=[IfName])

The type value in the protocols supported TLV field of the received LSPs mismatched with that supported by the local device.

Impact on the System

LSPs cannot be learnt, and routes cannot be generated.

Possible Causes

The protocol type supported by the source device of the received LSP was different from that supported by the local device.

Procedure

1. The value for the type in the protocols supported TLV field mismatched that supported by the local device. Check whether the fault is rectified 10 minutes later.

If so, go to Step 3.
If not, go to Step 2.

2. Collect log information and configuration information, and then contact technical support personnel.

3. End.
