ISSUE:  For interface models that have Live Links (Pipes) enabled, the Spectrum "BAD LINK DETECTED" alarm is clearing and reasserting even though the associated interface was down between asserted alarms. 

 

CAUSE:  While the "BAD LINK DETECTED" alarm with Probable Cause id 0x1040a exists, Spectrum lost snmp contact with the device. Then when Spectrum regained snmp contact with the device, Spectrum asserted the 0x10d2a event on the interface model. The 0x10d2a event is configured to clear the "BAD LINK DETECTED ALARM". The 0x10d2a event is NOT configured to be logged so it is not seen historically in the Events tab of the interface model.  The next time Spectrum polls the status of the interface, if it is still down, Spectrum asserts a new "BAD LINK DETECTED" alarm.

 

RESOLUTION:  Use the Event Configuration editor tool to remove the clearing of the "BAD LINK DETECTED" alarm with Probable Cause id 0x1040a from the 0x10d2a event.
