15.2.3 Configuring Maximum Times for 802.1x ID Authentication
When 802.1x authentication starts or 802.1x authentication is being performed again, 802.1x sends ID
authentication request to guest hosts. If the request message is dropped or delayed because network
problems, the requirement message will be sent again. If the message is resent certain times, 802.1x stops to
send the message and the ID authentication fails.
You can reset the maximum times of ID authentication request according to different network conditions,
ensuring the clients are authenticated successfully by the authentication server.
Run the following command in interface configuration command to set the maximum times for ID
authentication request:
Run… To
dot1x max-req count
Set the maximum times for ID
authentication request.
15.2.4 Configuring 802.1x Re-authentication
After first authentication is approved, the client will be authenticated every a certain time to ensure the legality
of the client. In this case, the re-authentication function needs to be enabled.
After the re-authentication function is enabled, 802.1x will periodically send the authentication request to the
host.
You can run the following commands to configure the re-authentication function.
Run… To
dot1x re-authentication

15.2.5 Configuring 802.1x Transmission Frequency
In the process of 802.1x authentication, data texts will be sent to the host. The data transmission can be
adjusted by controlling 802.1x transmission frequency so that the host response is successful.
Run the following command to configure the transmission frequency:
Run… To
dot1x timeout tx-period time
Set the message transmission frequency of 802.1x.
15.2.6 Configuring 802.1x User Binding
When 802.1x authentication is performed, you can bind a user to a certain port to ensure the security of port
access. Run the following command in interface configuration mode to start up 802.1x user binding.
