Configuring Authentication
Communicating with a TACACS+ Server
To enable communication between the TACACS+ security (database) server and the access server,
issue the commands listed in Table 7-2 in global configuration mode.
For example, to enable the remote TACACS+ server to communicate with the access server, enter
the commands as follows:
2511# configure terminal
2511(config)# tacacs-server host alcatraz
2511(config)# tacacs-server key abra2cad
The host name of the TACACS+ server in the previous example is alcatraz. The key (abra2cad) in
the previous example is the encryption key shared between the TACACS+ server and the access
server.
For more information about these commands, refer to the Security Command Reference, which is
part of the Cisco IOS configuration guides and command references documentation.
Communicating with a RADIUS Server
To enable communication between the RADIUS security (database) server and the access server,
issue the commands listed in Table 7-3 in global configuration mode.
For example, to enable the remote RADIUS server to communicate with the access server, enter the
commands as follows:
2511# configure terminal
2511(config)# radius-server host alcatraz
2511(config)# radius-server key abra2cad
The host name of the RADIUS server in the previous example is alcatraz. The key (abra2cad)inthe
previous example is the encryption key shared between the RADIUS server and the access server.
Table 7-2 Commands for Communicating with a TACACS+ Server
Command Purpose
tacacs-server host {hostname | ip-address} Specifies the IP address or the host name of the remote
TACACS+ server host. This host is typically a UNIX system
running TACACS+ software.
tacacs-server key shared-secret-text-string Specifies a shared secret text string used between the access
server and the TACACS+ server. The access server and
TACACS+ server use this text string to encrypt passwords
and exchange responses.
Table 7-3 RADIUS Server Commands
Command Purpose
radius-server host {hostname | ip-address} Specifies the IP address or the host name of the remote
RADIUS server host. This host is normally a UNIX system
running RADIUS software.
radius-server key shared-secret-text-string Specifies a shared secret text string used between the router
and the RADIUS server. The router and RADIUS server use
this text string to encrypt passwords and exchange responses.
