However, you do not have to enable all the ports of an associated device to process
flush messages received from the specified control VLAN. You need to enable this
function only on the ports that are on the active and backup links connecting the Smart
Link device and the target device. As shown in
function on GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 of Switch C,
GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 of Switch D, and GigabitEthernet
1/0/11 and GigabitEthernet 1/0/12 of Switch E.
Follow these steps to enable the specified port to process flush messages received
from the specified control VLAN:

1.2.4 Precautions

When configuring Smart Link, pay attention to the following points:
1) A port or a link aggregation group cannot serve as a member port for two smart
link groups. On the other hand, a port or a link aggregation group cannot serve as
a member for a smart link group and a monitor link group at the same time.
2) STP cannot be enabled on the member ports of a smart link group. An
STP-enabled port or a link aggregation group with an STP-enabled port cannot
serve as a member port for a smart link group.
3) A smart link/monitor link group with members cannot be deleted.
4) Smart Link/Monitor Link is mutually exclusive with remote port mirroring.
5) When a Combo port operates as a member port of a smart link group, the optical
port and the electrical port of the Combo port must not be both engaged with a
cable at the same time.
6) When you copy a port, the smart link/monitor link group member information
configured on the port will not be copied to other ports.
7) If a single port is specified as a member of a smart link/monitor link group, you
cannot execute the lacp enable command on this port or add this port into other
dynamic link aggregation groups, because these operations will make this port
become a link aggregation group member.
