PA820 high availability configuration

danoman2 — Tue, 18 Feb 2020 19:30:52 GMT

Hello,

I'm needing some clarification on one aspect of deploying a 2nd redundant PA820 in high availability mode. I currently have my 2nd 820 deployed with the management interface configured.

My first question is. When setting up my 2nd PA i discovered that I only have 10gb sfp's for interfaces that I'm matching on my current PA. The question is will this cause a conflict of some kind between the two devices.

I know in the past when deploying a pair of cisco asa 5515's that i needed to match the sfp's on both ends. Anyone able to confirm that?

Hello,

Yes the port speed and duplex must match on both devices.
