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.
