1-64) Smart Link/Monitor Link is mutually exclusive with remote port mirroring.5) If you configure both the Smart Link and Monitor Link functions on an Intelligent Resilient Fabric(IRF) enabled device, the Smart Link and Monitor Link functions will function abnormally. Thus, youare recommended to disable the IRF function when configuring the Smart Link or Monitor Linkfunction.6) When a Combo port operates as a member port of a smart link group, the optical port and theelectrical port of the Combo port must not be both engaged with a cable at the same time.7) When you copy a port, the smart link/monitor link group member information configured on the portwill not be copied to other ports.8) If a single port is specified as a member of a smart link/monitor link group, you cannot execute thelacp 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.9) If no control VLAN is configured for flush message processing, the device will forward receivedflush messages without processing them.10) If the control VLAN for receiving flush messages configured on an associated device is differentthan the one for sending flush messages configured on the corresponding Smart Link device, thedevice 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 amember port can process flush messages, this function cannot be synchronized to the other portsin the aggregation group automatically, that is, the other member ports in the aggregation groupcannot process flush messages. The function of processing flush messages must be manuallyconfigured for each port in the aggregation group.12) The VLAN configured as a control VLAN to send and receive flush messages must exist. Youcannot directly remove the control VLAN. When a dynamic VLAN is configured as the control VLANfor the smart link group, this VLAN will become a static VLAN, and the prompt information isdisplayed.Displaying and Maintaining Smart LinkTo do… Use the command… RemarksDisplay the information of asmart link groupdisplay smart-link group{ group-id | all }Display the statisticsinformation of flush messagesreceived and processed by thecurrent devicedisplay smart-link flushAvailable in any view.Clear flush message statistics reset smart-link packets counter Available in user view.Smart Link Configuration ExampleImplementing Link Redundancy BackupNetwork requirementsAs shown in Figure 1-3, Switch A is an H3C S5600 series Ethernet switch.
