mac-authen timer reauthenticate-period
Function
The mac-authen timer reauthenticate-period command sets the re-authentication interval for MAC address authentication users.
The undo mac-authen timer reauthenticate-period command restores the default re-authentication interval.
The default re-authentication interval for MAC address authentication users in the system view is 1800 seconds, and the re-authentication interval in the interface view is the same as the re-authentication interval configured in the system view.

Usage Guidelines
After enabling 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 set the re-authentication interval. The device then authenticates online users at the specified interval, ensuring that only authorized users can keep online.
If the command is executed in the system view, the function takes effect on all interfaces. If the command is executed in both system view and interface view, the function takes effect on the interface.
It is recommended that the re-authentication interval be set to the default value. If multiple ACLs need to be delivered during user authorization, you are advised to disable the re-authentication function or set a longer re-authentication interval to improve the device's processing performance.
In remote authentication and authorization, if the re-authentication interval is set to a shorter time, the CPU usage may be higher.
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.
