Configuring an Associated Device

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 active and standby links between the smart link device and the
destination device.
For example, as all the numbered ports on Device A, B, and D in
links from Devices C and E to Device A, you need to enable the ports to process flush messages
received from the control VLAN configured on Device C and E.
Follow these steps to enable the receiving of flush messages:
To do...
Enter system view
Enter Ethernet interface view or
Layer 2 aggregate interface view
Configure the control VLANs for
receiving 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 properly.
Make sure that the control VLANs are existing VLANs, and assign the ports capable of receiving
flush messages to the control VLANs.
Use the command...

smart-link flush enable
[ control-vlan vlan-id-list ]
