RichardF commented on an article I wrote last November and mentioned the prompt command in the ASA.  I never set aside any time to research it, but I finally took the time today while waiting for a maintenance window.

This is one of those little things in life that make me happy.  Since the active ASA always has the same hostname and IP address, I find it hard to keep track of to which firewall I’m actually connected.  That “configurtions are no long in sync” message you get when you conf t on the standby firewall really irks me.  With the prompt command, I can see which firewall I’m on and in what state it is.
