From: Aaron Leonard on 9 Jul 2010 14:13 on an aIOS AP, flash:env_vars (i.e. the bootloader variables) and nvram:startup-config are pretty much the whole of the config. Don't know why your IP address came back. The most elegant way of cleaning out the static IP address info from env_vars is: ap#write default-config This restores not only the startup-config but also env_vars to the defaults.

This is exactly what I was looking for. I look forward to trying this out next week. Bob |
