AAA Commands 243
authenticate to get to privileged EXEC mode. For example, if none is
specified as an authentication method after radius, no authentication is used
if the RADIUS server is down.
NOTE: Requests sent by the switch to a RADIUS server include the username
"$enabx$", where x is the requested privilege level. For enable to be authenticated
on Radius servers, add "$enabx$" users to them. The login user ID is also sent to
TACACS+ servers for enable authentication.
Example
The following example sets authentication when accessing higher privilege
levels.
console(config)# aaa authentication enable default

aaa authentication login
