(Optional) Associating a Minor Link Event with an Interface

(Optional) Associating a Minor Link Event with an Interface

Context

Minor link events include errored symbol events, errored frame events, and errored frame second events. If the number of code errors, errored frames, or errored frame seconds detected by an interface on a link in the configured period reaches or exceeds the configured threshold, the link is unavailable or has low quality. You can associate an EFM crossing event with an interface. Then the system sets the administrative status of the interface to Down. In this manner, all services on the interface are interrupted.

Perform the following steps at one or two ends of a link.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The view of the interface at one end of the link is displayed.

  3. Run efm threshold-event trigger error-down

    A threshold crossing event is associated with an interface.

    By default, no threshold crossing event is associated with an interface.

Follow-up Procedure

After associating a threshold crossing event with an interface, configure the interface to go administratively Up by using either of the following methods:
  • Run the error-down auto-recovery command in the system view to configure the interface to go administratively Up after the auto recovery delay.

  • Run the shutdown command and then the undo shutdown command in the interface view to restore the administrative status of the interface to Up.
