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
The following All ip interfaces down parameters can be controlled through the registry:
• is-correlation-allowed

• severity
• activate-flow
• correlate
• timeout
• weight
Note For more information about these parameters, see Chapter 6, “Event and Alarm Configuration
Parameters”.
