isisAttemptToExceedMaxSequence
Module: ISIS-MIB
OID (symbolic): ISIS-MIB::isisAttemptToExceedMaxSequence
OID (numeric): 1.3.6.1.2.1.138.0.4
Node type: NOTIFICATION-TYPE
Description:
When the sequence number on an LSP we generate wraps the 32-bit sequence counter, we purge and wait to re-announce this information. This notification describes that event. Since these should not be generated rapidly, we generate an event each time this happens.
While the first 6 bytes of the LSPID are ours, the other two contain useful information.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' ISIS-MIB::isisAttemptToExceedMaxSequence snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.138.0.4
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
