I noticed something interesting regargind HSRP and was wondering if someone could shed some light on the subject. I have two 6509e switches configured for HSRP on 10 different VLANs. The primary switch is set to Active using its default priority while the secondary switch is set to Standby with a priority of 110. This is for all VLANs. I noticed this morning that the Standby switch change its state from Standby to Active for 2 of the VLANs. However, the primary switch did NOT change from Active to Standby at all.
So how is it possible for 1 network device to become the Active device without the other device moving to Standby?
