Here is the layout. Two layer 2 switches connected on vlan 2. Each switch has one of a failover pair of pix running 6.3(4) attached on vlan 2. This is the outside interface of the pix. There are also an inside and a dmz on each pix but each pix is attached to the same switch on each of these interfaces. We are using serial failover cable between Pix(s).
Now what happens if the connection between the outside switches goes down but the pix interface to each switch is up. The failover "hello" for the vlan 2 interfaces do not get delivered but all other interfaces are fine. Each actual interface on the Pix in vlan 2 is "ok", they just can not communicate with each other. Each Pix will test its interface and fine it functional. So will they just stay in the same state, that is active will stay active or will the standby try to become active?
