Link Switching Failure in a Smart Link Group

Data flows are locked to the master or slave interface.

Check configuration of the Smart Link to see whether data flows are locked on an interface.
Run the display smart-link group group-id command and check the Link status field in the command output.

If the Link status field displays lock or force, data flows are locked to the master or slave interface. Run the undo smart-link { force | lock } command to remove the lock.
