We have two building next to each other and we have dark fiber connectivity between them.
I would like to know how do we configure HA betweeen them. how do i make use of dedicated HA ports.
Firewall models PA-3020 runn ing 8.0.7
This topic asks the same question:
if you just make sure your HA links are put in a vlan and transport that vlan across the dark fiber, you will be able to do this
If you don't have a spare set of strands to dedicate to HA you can pass it through a switch as @reaper mentioned, or if you do have a spare strand you can simply make a direct connection to the HA port without any additional equipment or configuration. Either method works perfectly fine.
Also make sure you have redundancy for your HA links. If one or both of the switches goes down, you could have a split-brain scenario where both PAN's are active until connectivity for the HA links is restored. I would suggest using device priority for this reason for when connectivity is restored.
