HSRP Coup
Counter
HSRP Coup events are counted in the HSRP Errors counter, which displays in the
Overview counters of Expert View. A Coup message indicates that the router
wishes to become active. A threshold can be set in Expert Alarms for HSRP Coup/
Resign packets, which includes both Resign and Coup HSRP messages.
Expert Symptom
HSRP Coup events are automatically logged as expert symptoms. The Symptom
Summary field provides the IP address of the router trying to become active. For
example:
SA=[206.250.226.11] DA=[206.250.228.69]
