Enabling the sending of flush messages
Restrictions and guidelines
The control VLAN configured for a smart link group must be different from the control VLAN configured for any other smart link group.
Make sure the configured control VLAN already exists, and assign the smart link group member ports to the control VLAN.
The control VLAN of a smart link group must also be one of its protected VLANs. Do not remove the control VLAN. Otherwise, flush messages cannot be sent correctly.
Procedure
Enter system view.
