272 CHAPTER 9: AAA AND RADIUS OPERATION
Perform the following configuration in system view.
Displaying and Debugging 802.1x
Execute the display command in all views to display the VLAN configuration, and
to verify the configuration. Execute the reset command in user view to reset
802.1x statistics information. Execute the debugging command in user view to
debug the 802.1x module.
Example: 802.1x
Configuration
As shown in the following figure, the workstation is connected to the 1/1/2 of the
Switch 8800.
The switch administrator will enable 802.1x on all the ports to authenticate the
supplicants in order to control their access to the Internet. The access control
mode is based on the MAC address.
All the supplicants belong to the default domain 3com163.net, which can contain
up to 30 users. RADIUS authentication is performed first. If there is no response
from the RADIUS server, local authentication will be performed. For accounting, if
the RADIUS server fails to account, the user will be disconnected. In addition,
when the user is connected, the domain name does not follow the user name.
Normally, if the user’s traffic is less than 2kbps, consistently, over a period of 20
minutes, they will be disconnected.
A server group, consisting of two RADIUS servers at 10.11.1.1 and 10.11.1.2, is
connected to the switch. The former one acts as the
primary-authentication/second-accounting server. The latter one acts as the
secondary-authentication/primary-accounting server. Set the encryption key as
“name” when the system exchanges packets with the authentication RADIUS
server, and “money” when the system exchanges packets with the accounting
RADIUS server. Configure the system to retransmit packets to the RADIUS server if
no response is received in 5 seconds. Retransmit the packet no more than 5 times
in all. Configure the system to transmit a real-time accounting packet to the
RADIUS server every 15 minutes. The system is instructed to transmit the user
name to the RADIUS server after removing the user domain name.
