I have a Pix 515E active/failover IOS v7.2 The failover process works perfect. I test powering down one unit, and then the other en works perfect. But, as soon as I do "write stanby" in the active unit, the passive unit goes down (the insde interface). I remember that one time the ASDM aske something about a "peer" while trying to configure the failover. What is that? why goes down? Thanks in advanced.
