High Avaibility problem A\P

L4 Transporter

There are two PA-500 firewalls in High Availability state A\P

After failover process the passive device become active but didnt pass the traffic.One possible reason which i suppose to be is the Gratious Arp packets are not send to the port of switch  (cisco 3850) which is connected to passive device

because when we type show mac-address interface <<number>> there are no virtual mac address


are there any other possible suggestions?

Did you happen to capture the GradARP packets on the passive device as it became active?







L7 Applicator


if you force the Grat ARP, does it show up on your switch?
