Configuration Guide 802.1x Configuration
Ruijie(config-if)# dot1x port-control auto
Ruijie(config)# end
When a port is set as a controlled port, only the EAP packets are allowed to pass; the packets to the CPU are also under
control.
If you hope that cpu can not receive non-EAP packet from any controlled port, you can separate management VLAN
from user VLAN.
Enabling Timed Re-authentication
The 802.1x can ask users for re-authentication at periodical intervals, to prevent authorized users from being used by
other users. This can also detect disconnection, making more accurate charging. In addition to the re-authentication
switch, you can also define the re-authentication interval, which is 3600 seconds by default. In the case of charging based
on duration, you should determine the re-authentication interval according to the specific network size, which should be
sufficient while as accurate as possible.
In the privileged EXEC mode, you can enable/disable re-authentication and set the re-authentication interval by
performing the following steps.
Ruijie(config)#dot1x re-authentication
Enable timed re-authentication.
Ruijie(config)#dot1x timeout re-authperiod seconds
Set the re-authentication interval.
Show the dot1x configurations.
You can use the no dot1x re-authentication command to disable timed re-authentication, and use the no dot1x timeout
re-authperiod command to restore the re-authentication interval to the default.
The following example enables re-authentication and sets the re-authentication interval as 1000 seconds.
Ruijie# configure terminal
Ruijie(config)# dot1x re-authentication
Ruijie(config)# dot1x timeout re-authperiod 1000
Ruijie(config)# end
Ruijie# show dot1x
