recover efm-down

Function

The recover efm-down command changes the EFM OAM protocol state of an interface from Down to Up.

By default, the EFM OAM protocol state of an interface is Down.

Usage Guidelines

Usage Scenario

If the efm trigger if-down command is run to associate EFM OAM with an interface, the EFM OAM protocol state of the interface does not change from Down to Up when a link connectivity fault is rectified. To change the EFM OAM protocol state of the interface from Down to Up, run the recover efm-down command.

Prerequisites

EFM OAM has been associated with an interface.

Configuration Impact

After the recover efm-down command is run, the EFM OAM protocol state of an interface changes from Down to Up immediately after a link connectivity fault is rectified. The interface can then forward all packets and process all Layer 2 and Layer 3 services.

Precautions

After the recover efm-down command is run on an interface, all packets on the interface are forwarded. Therefore, exercise caution when running this command.

Example

# Change the EFM OAM protocol state of GE 0/1/1 from Down to Up.
