2 Set the access control mode. (This command could not be configured, when it is
configured as MAC-based by default.)
[4500]dot1x port-method macbased interface Ethernet 1/0/1
3 Create the RADIUS scheme radius1 and enters its view.
[4500]radius scheme radius1
4 Set IP address of the primary authentication/accounting RADIUS servers.
[4500-radius-radius1]primary authentication 10.11.1.1
[4500-radius-radius1]primary accounting 10.11.1.2
5 Set the IP address of the second authentication/accounting RADIUS servers.
[4500-radius-radius1]secondary authentication 10.11.1.2
[4500-radius-radius1]secondary accounting 10.11.1.1
6 Set the encryption key when the system exchanges packets with the
authentication RADIUS server.
[4500-radius-radius1]key authentication name
7 Set the encryption key when the system exchanges packets with the accounting
