l Run the efm holdup-timer command in the interface view to configure the interface to go
administratively Up after the auto-recovery delay.
l Run the shutdown command and then the undo shutdown command in the interface view
to restore the administrative state of the interface to Up.
4.4.6 Checking the Configuration
By viewing EFM OAM configurations, you can check whether the configurations are successful.
Prerequisite
The configurations of the EFM OAM link monitoring function are complete.
Procedure
l Run the display efm { all | interface interface-type interface-number } command to check
information about EFM OAM on an interface.
l Run the display efm session { all | interface interface-type interface-number } command
to check the status of the EFM OAM protocol on an interface.
----End
Example
Run the display efm command. You can view information about link monitoring on the
interface. For example:
<Quidway> display efm interface xgigabitethernet 0/0/1
