Example
The following example configures RADIUS servers at 1.1.1.1, 2.2.2.2, and
3.3.3.3. It sets the front panel ports to use multi-auth authentication. CoA is
configured for two RADIUS servers located at 1.1.1.1 and 2.2.2.2 using a

secret. CoA disconnect requests are accepted from these servers. Any
authentication type is allowed for CoA disconnect requests.
