How multi-device port authentication works
The request for authentication from the RADIUS server is successful only if the username and
password provided in the request matches an entry in the users database on the RADIUS server.
When this happens, the RADIUS server returns an Access-Accept message back to the Brocade
device. When the RADIUS server returns an Access-Accept message for a MAC address, that MAC
address is considered authenticated, and traffic from the MAC address is forwarded normally by
the Brocade device.
Authentication-failure actions
If the MAC address does not match the username and password of an entry in the users database
on the RADIUS server, then the RADIUS server returns an Access-Reject message. When this
happens, it is considered an authentication failure for the MAC address. When an authentication
failure occurs, the Brocade device can either drop traffic from the MAC address in hardware (the
default), or move the port on which the traffic was received to a restricted VLAN.
