RADIUS Protocol in FIPS Mode

HMAC-MD5 authentication used in RADIUS is allowed in FIPS mode.

RADIUS allows client-to-server authentication. To authorize an authentication, use commands such as the following to configure shared secret keys for RADIUS:

device(config)# radius-server host 1.2.3.4 auth-port < auth-port > 1812 acct-port 1813 default
key 1 Example01

[ no ] radius-server host { ip-addr | server-name } [ auth-port number [ acct-port number ] [ authentication-only | accounting-only | default ] [ key [ 0 1 2 ] string [ dot1x ] ] ]
