• Server IP Address—Enter the TACACS+ server IP address.

server. The key must match the encryption key configured on the TACACS+
server. Select Use Default to use the key string defined under the TACACS+
Default Parameters.
• Timeout for Reply—Enter the amount of time that passes before the
connection between the switch and the TACACS+ server times out. Select
Use Default to use the default value displayed on the page.
• Authentication IP Port—Enter the port number through which the
TACACS+ session occurs. The default is port 49.
• Single Connection—Select to enable a single open connection between
the switch and the TACACS+ server.
STEP 4 Click Apply. The TACACS+ server is added, and the switch is updated.
Configuring RADIUS Parameters
Remote Authorization Dial-In User Service (RADIUS) servers provide a centralized
802.1X or MAC-based network access control. The switch is a RADIUS client that
relies on a RADIUS server to provide centralized security, authorizing and
authenticating users attempting to access and administer the switch.
For the RADIUS server to grant access to the web-based switch configuration
utility, the RADIUS server must return cisco-avpair = shell:priv-lvl=15.
Use this page to enable the configuration of the RADIUS server parameters the
switch uses to communicate with the servers.
