Configure the control VLANs for
receiving flush messages
smart-link flush enable [ control-
vlan vlan-id-list ]
Required
By default, no control VLAN exists
for receiving flush messages.
CAUTION:
 Configure all the control VLANs to receive flush messages.
 If no control VLAN is specified for processing flush messages, the device forwards the received flush messages
without processing them.
 Make sure that the receive control VLAN is the same as the transmit control VLAN configured on the smart link
device. If they are not the same, the associated device will forward the received flush messages directly without
any processing.
 Do not remove the control VLANs. Otherwise, flush messages cannot be sent properly.
 Make sure that the control VLANs are existing VLANs, and assign the ports capable of receiving flush messages
to the control VLANs.

Network requirements
As shown in Figure 24:
 Device C and Device D are smart link devices, and Device A, Device B, and Device E are

Device A.
 Configure Smart Link on Device C and Device D for dual uplink backup.
