Command Modes Configuration mode Command History Release 4.0(0)N1(1a) Modification This command was introduced. 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.
