ISSUE: After shutting down HSRP interfaces on both the primary and secondary routers, CA Spectrum is asserting "Router Redundancy Lost" alarms:

 

MajorNov 13, 2014 2:25:28 AM CST192.168.2.2Router Redundancy Lost - The HSRP group with virtual IP address 192.168.2.2 has lost all its fail over routers causing redundancy to be lost for this virtual IP.System0xc4007902CiscoHSRPVDevNov 13, 2014 4:42:20 AM CSTspectrum@SpectroSERVER

 

ROOT CAUSE: The interface(s) in question are still configured interfaces on the device but are in the "shutdown" state. Although shut down, it is still a configured interface on the device and the mibs will still reflect it as a configured interface.

 standby 1 ip 192.168.2.2

 

RESOLUTION: The best solution is to remove the configuration for the interface from the device configuration. As a work around, set the HSRPMode attribute 0x21174f to Off or Passive on the associated CiscoHSRPApp model should stop Spectrum from polling every poll cycle:

Off

The HSRP table is not polled.

Passive

The HSRP table is polled once at the activation. Otherwise, CA Spectrum relies on updates from traps to update this information.

Active

The HSRP table is polled every poll interval in addition to the passive processing.
