Smart Link configuration task list
A smart link device is a device that supports Smart Link and is configured with a smart link group and a
transmit control VLAN for flush message transmission. Device C and Device D in
Figure 22
are two
examples of smart link devices.
An associated device is a device that supports Smart Link and receives flush messages sent from the
specified control VLAN. Device A, Device B, and Device E in
Figure 22
are examples of associated
devices.
Complete the following tasks to configure Smart Link:

Configuration prerequisites
Before configuring a port as a smart link group member, shut down the port to prevent loops. You
can bring up the port only after completing the smart link group configuration.
Disable the spanning tree feature and RRPP on the ports that you want to add to the smart link group,
and make sure the ports are not member ports of any aggregation group or service loopback
group.
NOTE:
A loop may occur on the network during the time when the spanning tree feature is disabled but Smart Link
has not yet taken effect on a port.
Configuring protected VLANs for a smart link group
You can configure protected VLANs for a smart link group by referencing MSTIs. Before configuring the
protected VLANs, configure the mappings between MSTIs and the VLANs to be protected. For more
information about MSTI, see
Layer 2—LAN Switching Configuration Guide
.
To configure the protected VLANs for a smart link group:
