Enabling the sending of flush messages

Follow these guidelines when you enable the sending of flush messages:
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.
