Configuring the Delay in Reporting Physical Status Changes

Configuring the Delay in Reporting Physical Status Changes

Context

The physical status of an Ethernet interface can be Up or Down. When the physical status changes, the system notifies upper-layer protocol modules (such as the routing and forwarding modules) of the change to direct packet receiving and forwarding. The system also automatically generates traps and logs to remind users to perform corresponding operations on physical links. For example, when the physical status of the active interface in an interface protection group changes from Up to Down, the system immediately instructs the upper-layer service forwarding protocol to send service packets from the standby interface.

If frequent physical status changes are reported to the system, extra system costs are generated. You can configure the delay in reporting physical status changes to solve the problem. The system is unaware of the physical status changes on interfaces within the configured delay. If the interface physical status is not recovered after the delay expires, the physical status changes are reported to the system.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run carrier { up-hold-time | down-hold-time } interval

    The delay in reporting physical status changes is configured.

    By default, the delay in reporting an interface Up event is 2000 milliseconds and the delay in reporting an interface Down event is 0 milliseconds.

    You can configure the delay in reporting physical status changes based on the network connection status.
    • Setting a long delay

      For example, an interface frequently alternates between Up and Down states at an interval shorter than the IP route convergence time. In this case, the upper-layer protocol does not need to sense the physical status changes. You can set a long delay in reporting physical status changes to avoid unnecessary routing entry refreshing caused by frequent physical status changes.

    • Setting a short delay

      For example, when the physical status of the active interface in an interface protection group changes from Up to Down, the system needs to immediately instruct the upper-layer service forwarding protocol to send service packets from the standby interface. In this case, you can set a short delay in reporting physical status changes to ensure real-time service switchover.
