If no control VLAN is configured for flush message processing, the device will forward received 
flush messages without processing them. 
If the control VLAN for receiving flush messages configured on an associated device is different 
than the one for sending flush messages configured on the corresponding Smart Link device, the 
device will forward received flush messages without processing them. 
In the static or manual link aggregation group which serves as a smart link group member, if a 
member port can process flush messages, this function cannot be synchronized to the other ports 
in the aggregation group automatically, that is, the other member ports in the aggregation group 
cannot process flush messages. The function of processing flush messages must be manually 
configured for each port in the aggregation group.  
The VLAN configured as a control VLAN to send and receive flush messages must exist. You 
cannot directly remove the control VLAN. When a dynamic VLAN is configured as the control VLAN 
for the smart link group, this VLAN will become a static VLAN, and the prompt information is 
displayed.
