Apply the method list to terminal lines
To enable RADIUS AAA login authentication for a method list, you must apply it to a terminal line. To
configure a terminal line for RADIUS authentication and authorization, enter the following commands:
Specify a RADIUS server host
When configuring a RADIUS server host, you can set different communication parameters, such as the
UDP port, the key password, the number of retries, and the timeout.
To specify a RADIUS server host and configure its communication parameters, use the following
command in the CONFIGURATION mode:
aaa authorization exec
{method-list-name | default} radius
tacacs+
CONFIGURATION Create methodlist with RADIUS and TACACS+ as
authorization methods. Typical order of methods:
RADIUS, TACACS+, Local, None. If authorization is
denied by RADIUS, the session ends (radius should not
be the last method specified).
