ASA HA PROTOCOL

Hi experts,

ASA HA PROTOCOL

High availablility comes in many flavours on the ASA, but I assume you are talking about failover?

Although some people think that it is HSRP because it is configured with a "standby" keyword, it's a proprietary communication that is (to my knowledge) not publicly documented by Cisco.

If you run a capture you can see the protocol, I think it is 150,  proprietary protocol.
