Configuring a Smart Link Device

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 STP and RRPP on the ports you want to add to the smart link group, and make sure that
the ports are not member ports of any aggregation group or service loopback group.
A loop may occur on the network during the time when STP is disabled but Smart Link has not yet taken
effect on a port.
