9) If no control VLAN is configured for flush message processing, the device will
forward received flush messages without processing them.
10) If the control VLAN for receiving flush messages configured on an associated
device is different than the one for sending flush messages configured on the
corresponding Smart Link device, the device will forward received flush messages
without processing them.
11) In the static or manual link aggregation group which serves as a smart link group
member, if a member port can process flush messages, this function cannot be
synchronized to the other ports in the aggregation group automatically, that is, the
other member ports in the aggregation group cannot process flush messages. The
function of processing flush messages must be manually configured for each port
in the aggregation group.
12) The VLAN configured as a control VLAN to send and receive flush messages must
exist. You cannot directly remove the control VLAN. When a dynamic VLAN is
configured as the control VLAN for the smart link group, this VLAN will become a
static VLAN, and the prompt information is displayed.
