I had a PIX515e fail on me last week. I had to jump through some hoops. I had to get a replacement and then reload the config. When I reloaded the config a series of commands were omitted. NAT’s and Crypto’s mainly. I think this was because I had an enhanced security key installed on it and the key was not initially installed.
Post I am trying to learn from this so in the event I have another failure I can recover quicker. I think the recovery process should be:
1. Install the correct IOS
2. Install the correct license keys
3. TFTP the config on to the PIX
Any comments would be appreciated. Thanks.
