Example
The following example configures RADIUS servers at 1.1.1.1, 2.2.2.2, and
3.3.3.3 and CoA clients at 3.3.3.3, 4.4.4.4, and 5.5.5.5. It sets the front panel
ports to use 802.1x MAC-based authentication. CoA is configured for two
RADIUS servers located at 1.1.1.1 and 2.2.2.2 using a global shared secret and
a third server using a server specific shared secret. CoA and disconnect
requests are accepted from these servers. Any authentication type is allowed
for CoA and disconnect requests.
