request interface link-degrade-recover
Syntax
request interface link-degrade-recover interfaces-name
Description
Manually recover a degraded physical link. Manual recovery is used when the interface has any Layer 2 and Layer 3 protocols that prevents autorecovery. This command is applicable only if you have configured the manual link recovery option on the interface.
Note:
Manual recovery option is recommended for user deployments that have static route configurations causing the remote end of the link to start forwarding packets (as soon as the physical link is up) while auto-recovery is in progress.
