As shown in Figure 1-2, you need to enable thisfunction on Ethernet 1/0/2 and Ethernet 1/0/3 of Switch C, Ethernet 1/0/2 and Ethernet1/0/3 of Switch D, and Ethernet 11/0/1 and Ethernet 1/0/12 of Switch E.Table 1-4 Enable the specified port to process flush messages received from thespecified control VLANOperation Command RemarksEnter system view system-view —Systemviewsmart-link flush enablecontrol-vlan vlan-id portinterface-type interface-number [ tointerface-type interface-number ]interface interface-typeinterface-numberEnable thespecifiedport(s) toprocess flushmessagesreceivedfrom thecontrol VLANEthernetport view smart-link flush enablecontrol-vlan vlan-idRequired, useeitherapproach.By default, nocontrol VLANfor receivingflushmessages isspecified.1.2.4 PrecautionsWhen 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 SmartLink groups. On the other hand, a port or a link aggregation group cannot serve asa 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. AnSTP-enabled port or a link aggregation group with an STP-enabled port cannotserve 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 opticalport and the electrical port of the Combo port must not be both engaged with acable at the same time.6) When you copy a port, the Smart Link/Monitor Link group member informationconfigured 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, youcannot execute the lacp enable command on this port or add this port into otherdynamic link aggregation groups, because these operations will make this portbecome a link aggregation group member.8) If no control VLAN is configured for flush message processing, the device willforward received flush messages without processing them.
