Network requirements
As shown in Figure 1-1, Switch A is an H3C S3600 series Ethernet switch. All Switches in Figure 1-1 support Smart Link.
To enable a remote PC to access the server reliably, perform these configurations on the switches:
1) Configure the smart link device Switch A as follows:
l Create a smart link group and assign member ports to the group.
l Specify the control VLAN for transmitting Flush messages.
2) Enable the specified ports on Switch C, Switch D, and Switch E to receive and process Flush messages from the control VLAN.

Precautions
l 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.
l Smart Link is mutually exclusive with remote port mirroring.
l If you configure the Smart Link function on an Intelligent Resilient Fabric (IRF) enabled device, the Smart Link function will function abnormally. Thus, you are recommended to disable the IRF function when configuring the Smart Link function.
l 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.
l When you copy a port, the smart link group member information configured on the port will not be copied to other ports.
l If a single port is specified as a member of a smart 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.
l If no control VLAN is configured for flush message processing, the device will forward received flush messages without processing them.
l 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.
l 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.
l 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.

Figure 1-2 Network diagram for Monitor Link configuration
Network requirements
As shown inFigure 1-2, the PCs access the server and Internet through the switch. Configure Smart Link and Monitor Link to prevent the PCs from failing to access the server and Internet due to uplink link or port failure.
Configure the switches as follows:
l Create a smart link group on Switch A and Switch B, and specify the control VLAN for transmitting Flush messages.
l Create a monitor link group on Switch C and Switch D.
l Enable the specified ports on Switch C, Switch D, and Switch E to receive and process Flush messages from the control VLAN.

Precautions
l You cannot assign a port or link aggregation group to more than one smart link group or to a smart link group and monitor link group at the same time.
l Smart Link is mutually exclusive with remote port mirroring.
l 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, you are recommended to disable the IRF function when configuring the Smart Link or Monitor Link function.
l If a single port is specified as a smart link/monitor link group member, do not use the lacp enable command on the port or add the port to another dynamic link aggregation group because doing so will cause the port to become an aggregation group member.
l Using the copy command on a port does not copy the smart link/monitor link group member information configured on the port to any other port.
