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 subordinate links between the
smart link device and the destination device.
To enable the receiving of flush messages:
To do...
Enter system view
Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view
Configure the control VLANs
for receiving flush messages
Configure all 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.

Displaying and maintaining Smart Link

To do...
Display smart link group
Display information about the
received flush messages
Clear the statistics about flush
Use the command...
interface interface-type interface-
smart-link flush enable [ control-
vlan vlan-id-list ]
Use the command...
display smart-link group { group-id |
all } [ | { begin | exclude | include }
regular-expression ]
display smart-link flush [ | { begin |
exclude | include } regular-expression
reset smart-link statistics
By default, no control VLAN exists
for receiving flush messages
