manually or statically are available).

Description
Use the link-aggregation group command to configure a link aggregation group as a member of the
Smart Link group.
Use the undo link-aggregation group command to remove the specified link aggregation group from
the current Smart Link group.
Because Smart Link and STP cannot be enabled on an Ethernet port at the same time, you must make
sure that STP is disabled on the port before assigning the port to a smart link group.
