Enter the RADIUS host IP address(es)

If you select either eap-radius or chap-radius for the authentication method, configure the switch to use 1, 2, or 3 RADIUS servers for authentication. The following syntax shows the basic commands. For coverage of all commands related to RADIUS server configuration, see RADIUS Authentication, Authorization, and Accounting.

Syntax:

radius host <ip-address>

Adds a server to the RADIUS configuration.

[key <server-specific key-string>]

Optional. Specifies an encryption key for use during authentication (or accounting) sessions with the specified server. This key must match the key used on the RADIUS server. Use this option only if the specified server requires a different key than configured for the global encryption key. The tilde (~) character is allowed in the string. It is not backward compatible; the “~” character is lost if you use a software version that does not support the “~” character.

Syntax:

radius-server key <global key-string>

Specifies the global encryption key the switch uses for sessions with servers for which the switch does not have a server-specific key. This key is optional if all RADIUS server addresses configured in the switch include a server-specific encryption key. The tilde (~) character is allowed in the string, for example, radius-server key hp~switch. It is not backward compatible; the “~” character is lost if you use a software version that does not support the “~” character.

Default: Null

The no form of the command removes the global encryption key.
