Usage Scenario
After configuring the re-authentication function for online MAC address authentication users using the mac-authen reauthenticate command, run the mac-authen timer reauthenticate-period command to configure the re-authentication interval. The device then re-authenticates online users at the specified interval, ensuring that only authorized users can keep online.
Precautions
Generally, the default re-authentication interval is recommended. If many ACL rules need to be delivered during user authorization, to improve the device processing performance, you are advised to disable re-authentication or increase the re-authentication internal. When remote authentication and authorization are used and a short re-authentication interval is used, the CPU usage may become high.
MAC address authentication users who go online through a VLANIF interface do not support re-authentication.
To reduce the impact on the device performance when many users exist, the user re-authentication interval may be longer than the configured re-authentication interval.
# In the MAC access profile mac_access_profile, configure the re-authentication interval for online MAC address authentication users to 2000 seconds.
