Network requirements
z
It is required to use the access control method of macbased on the port GigabitEthernet 2/0/1 to
control clients.
z
All clients belong to default domain aabbcc.net, which can accommodate up to 30 users. RADIUS
authentication is performed at first, and then local authentication when no response from the
RADIUS server is received. If the RADIUS accounting fails, the device gets users offline.
z
A server group with two RADIUS servers is connected to the device. The IP addresses of the
servers are 10.1.1.1 and 10.1.1.2 respectively. Use the former as the primary
authentication/secondary accounting server, and the latter as the secondary
authentication/primary accounting server.
