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 the 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; you only need to enable those on the master and slave links between the smart
link device and the destination device.
Configuration guidelines
•
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 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 the control VLANs are existing VLANs, and assign the ports capable of receiving flush
messages to the control VLANs.
Configuration procedure
To enable the receiving of flush messages:
