Connecting PA820 to Cisco ASA HA

Hi All,


I want to connect PA820 to ASA HA setup. ASA1 and ASA2 need to connect to PA820. Can I use link aggregation on PA820 for this scenario? If one of the ASAs fails will this setup work to pass on the traffic using the other ASA.


Thank you.

So you have 2x ASA's and 1x PAN? Dont think an AE would work, I could be wrong. How about making the physical interfaces on the PAN layer 2 and making the vlan interface on the PAN layer3. This way the two PAN ports are just 'switch' ports.

Actually AE ports would work perfectly fine here as the non-active port would simply be shown as 'down' as the HA process in ASA shuts down the ports. However, @OtakarKlier's method is better then AE interfaces in this situation.
