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 if a topology change occurs.
Enabling the receiving of flush messages
You do not need to enable all ports on the associated devices to receive flush messages. Enable the
feature only on all control VLANs of ports 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:
• If no control VLAN is specified for processing flush messages, the device forwards the received
flush messages without any processing.
• Make sure 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 the control VLANs are existing VLANs, and assign the ports capable of receiving
flush messages to the control VLANs.
