I would like a pix to first look to a tacacs server to login, then use the local database if the tacacs server is not available. I can find the commands to do either, but not both. For instance with a tacacs server mytacacs:
aaa authentication serial console mytacacs or for local aaa authentication serial console LOCAL
To get what I want can I use a single combo command like a router or will two commands work, ie
aaa authentication serial console mytacacs LOCAL
or
aaa authentication serial console mytacacs aaa authentication serial console LOCAL
as separate statements? I have no easy lab pix to play with and the command reference statements online show only one or the other.
