Usage Guidelines
Usage Scenario
When link monitoring is configured for an interface on a link, the link is considered unavailable, if the number of errored frames, errored codes, or errored frame seconds detected by the interface reaches or exceeds the threshold within a period. 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.
By default, an interface can only be resumed by a network administrator after being shut down. To configure the interface to restore to the Up state automatically, run the error-down auto-recovery command to set an auto recovery.
