Figure 47-3: The Topology of IPv6 RADIUS configuration
A computer connects to a switch, of which the IP address is 2004:1:2:3::2 and connected with
a RADIUS authentication server without Ethernet1/2; IP address of the server is 2004:1:2:3::3
and the authentication port is defaulted at 1812, accounting port is defaulted at 1813.
Configure steps as shown below:
Switch(config)#interface vlan 1
Switch(Config-if-vlan1)#ipv6 address 2004:1:2:3::2/64
Switch(Config-if-vlan1)#exit
Switch(config)#radius-server authentication host 2004:1:2:3::3
Switch(config)#radius-server accounting host 2004:1:2:3::3
Switch(config)#radius-server key test
Switch(config)#aaa enable
Switch(config)#aaa-accounting enable
47.4 RADIUS Troubleshooting
In configuring and using RADIUS, the RADIUS may fail to authentication due to reasons such
as physical connection failure or wrong configurations. The user should ensure the following:
 First make sure good condition of the RADIUS server physical connection
 Second all interface and link protocols are in the UP state (use “show interface”
command)
 Then ensure the RADIUS key configured on the switch is in accordance with the one
configured on RADIUS server
 Finally ensure to connect to the correct RADIUS server
