Chapter 4 Advanced Correlation Scenarios

IP Interface Failure Scenarios

The following failures are identified in the network:

•A link-down alarm is generated on the PE.

•An ip interface status down alarm is generated on the PE.

•A device unreachable alarm is generated on the CE.

The following correlation information is provided:

•Link down on the PE:

–The ip interface status down alarm on the PE is correlated to the link-down alarm.

–The device unreachable alarm on the CE is correlated to the link-down alarm on the PE.

–The traps and syslogs for the subinterface are correlated to the link down alarm on the PE

Interface Registry Parameters

ip interface status down Parameters

The following ip interface status down parameters can be controlled through the registry:

•is-correlation-allowed

•severity

•timeout

•time-stamp-delay

•weight

•is-ticketable

Note For more information about these parameters see Chapter 6, “Event and Alarm Configuration Parameters”.

All ip interfaces down Parameters
