(Optional) Configuring the User Logout Delay Function When an Interface Link Is Faulty
Context
If a link is faulty, the interface is interrupted and users are directly logged out. To solve this problem, you can configure the user logout delay function. When the interface link is faulty, the users remain online within the delay. In this case, if the link is restored, the users do not need to be re-authenticated. If the users are disconnected after the delay and the link is restored, the users need to be re-authenticated.
This function takes effect only for wired users who go online on Layer 2 physical interfaces that have been configured with NAC authentication.
To make the function take effect, it is recommended that the configured interval be greater than the time during which the interface is in Up state. If the link frequently flaps within a short period, it is recommended that the interval be set to unlimited.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run link-down offline delay { delay-value | unlimited }
The user logout delay is configured when an interface link is faulty.
The default user logout delay is 10 seconds when an interface link is faulty.
If the delay is 0, users are logged out immediately when the interface link is faulty. If the delay is unlimited, users are not logged out when the interface link is faulty.
