ASA Erase Config Commands

[chrisbicm]

Just wondering the easiest method to clear my config on an ASA 5520 and start "from scratch".... I have an old config on my ASA that I am looking erase but last time I tried to do this I ended up deleting my asa704-k8.bin file and ended up in a world of hurt. (I had been working with an older version of the IOS on some routers and switches... I miss the good old erase run, erase start)

Thanks,

Chris

Dennt,

Thanks for the quick response, I know it was a pretty lame question... I just wanted to make sure before I ended up messing anything up. So if I issue the "write erase" command I am sure it will prompt me first I say yes... and then it should just load up with no interfaces configured just like "new"??

Thanks a lot,

Chris

If you already have 7.0(x) or better code installed, then you could also reset it to "factory default" with the following command:

configure factory-default [ip_address [mask]]

Using this command will reset it like it just came from Cisco.

A write erase will clear the entire config. If you clear it, make sure when you write your new config that you put things like your boot system variable in.

I just change firewall modes, transparent to routed or vice versa. This will wipe out the config.
