I have a pair of 5540 firewalls.
Currently secondary is active .2 and primary is in standby .3 mode.
The problem is that I am not able to ping from active to standby IP and vice versa.
Even though I can ping them both from the local network.
I can ping without any problem other IP's configured on other interfaces from both the firewalls.
I tried shut noshut of GigE0/0 of primary firewall.
Clear arp on both the firewalls, still not able to ping each other.
