Chapter 11 Configuring RADIUS and Servers
Configuring and Enabling
To remove the specified server name or address, use the
no tacacs-server host
hostname
global configuration command. To remove a server group from the configuration list, use the
no aaa
group server
group-name
global configuration command. To remove the IP address of a
server, use the
no server ip-address
server group subconfiguration command.
Configuring Login Authentication
To configure AAA authentication, you define a named list of authentication methods and then apply that
list to various interfaces. The method list defines the types of authentication to be performed and the
sequence in which they are performed; it must be applied to a specific interface before any of the defined
authentication methods are performed. The only exception is the default method list (which, by
coincidence, is named
default
). The default method list is automatically applied to all interfaces except
those that have a named method list explicitly defined. A defined method list overrides the default
method list.
A method list describes the sequence and authentication methods to be queried to authenticate an
administrator. You can designate one or more security protocols to be used for authentication, thus
ensuring a backup system for authentication in case the initial method fails. The software uses the first
method listed to authenticate users; if that method fails to respond, the software selects the next
authentication method in the method list. This process continues until there is successful communication
with a listed authentication method or until all defined methods are exhausted. If authentication fails at
any point in this cycle—meaning that the security server or local username database responds by denying
the administrator access—the authentication process stops, and no other authentication methods are
attempted.
Beginning in privileged EXEC mode, follow these steps to configure login authentication:
Step 5
server
ip-address
(Optional) Associate a particular server with the defined server
group. Repeat this step for each server in the AAA server
group.
Each server in the group must be previously defined in Step 2.
Step 6
end
Return to privileged EXEC mode.
Step 7
show tacacs
Verify your entries.
Step 8
copy running-config startup-config
(Optional) Save your entries in the configuration file.
