Step
3. Enable flush update in the
specified control VLAN.
Configuring the collaboration between Smart Link and CC of
CFD
When configuring the collaboration between Smart Link and the CC function of CFD on a smart link
member port, make sure that the control VLAN of the smart link group to which the port belongs
matches the detection VLAN of the CC function of CFD.
To configure the collaboration between Smart Link and the CC function of CFD on a smart link
member port:
Step
1. Enter system view.
2. Enter Ethernet interface
view.
3. Configure the collaboration
between Smart Link and the
CC function of CFD on the
port.

Configuring an associated device

Configuration prerequisites

Disable the spanning tree feature on the associated device's ports that connect to the member ports
of the smart link group; otherwise, the ports will discard flush messages when they are not in
forwarding state in case of a topology change.

Enabling the receiving of flush messages

You do not need to enable all ports on the associated devices to receive flush messages sent from
the transmit control VLAN, only those on the primary and secondary links between the Smart Link
device and the destination device.
Follow these guidelines when you enable the receiving of flush messages:
•
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 correctly.
•
Make sure that the control VLANs are existing VLANs, and assign the ports capable of
receiving flush messages to the control VLANs.
