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 master and slave links between the smart link device and the
Follow these steps to enable the receiving of flush messages:
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.
Associated Device Configuration Example
Configure GigabitEthernet 1/0/1 to receive and process flush messages in VLAN 20.
[Sysname] vlan 20
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port link-type trunk
[Sysname-GigabitEthernet1/0/1] port trunk permit vlan 20
[Sysname-GigabitEthernet1/0/1] smart-link flush enable control-vlan 20
Use the command...
smart-link flush enable
[ control-vlan vlan-id-list ]
By default, no control
VLAN exists for receiving
