Usage Guidelines

Usage Scenario

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.

Precautions

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.

Example

# Configure the user logout delay to 5 seconds when the link of GE0/0/1 is faulty.
