Configuring a Smart Link device
Configuration prerequisites
Before configuring a Smart Link device, complete the following tasks:
• To prevent loops, shut down a port before configuring it as a smart link group member. You can
bring up the port only after completing the smart link group configuration.
• Disable the spanning tree feature and RRPP on the ports you want to add to the smart link
group.
NOTE:
• A loop might 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.
• If you configure a port as both an aggregation group member and a smart link group member,
only the aggregation group configuration takes effect. The port is not shown in the output from
the display smart-link group command. The smart link group configuration takes effect after
the port leaves the aggregation group.
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 configure the protected VLANs for a smart link group:
