Command History
Usage Guidelines The group radius, group tacacs+, and group group-list methods refer to a set of previously defined
RADIUS or TACACS+ servers. Use the radius-server host or tacacs-server host command to
configure the host servers. Use the aaa group server command to create a named group of servers.
If you specify the group method or local method and they fail, then the authentication fails. If you
specify the none method alone or after the group method, then the authentication always succeeds.
Examples This example shows how to configure the AAA authentication console login method:
switch(config)# aaa authentication login default group radius
This example shows how to revert to the default AAA authentication console login method:
switch(config)# aaa authentication login default group radius
group Specifies that a server group be used for authentication.
