authentication server without Ethernet1/2; IP address of the server is 10.1.1.3 and the authentication port is
defaulted at 1812, accounting port is defaulted at 1813.
Configure steps as below:
Switch(config)#interface vlan 1
Switch(Config-if-vlan1)#ip address 10.1.1.2 255.255.255.0
Switch(Config-if-vlan1)#exit
Switch(config)#radius-server authentication host 10.1.1.3
Switch(config)#radius-server accounting host 10.1.1.3
Switch(config)#radius-server key test
Switch(config)#aaa enable
Switch(config)#aaa-accounting enable
