An associated device mentioned in this document refers to a device that supports Smart Link and 

locally configured to process flush messages received from the specified control VLAN so as to work 

with the corresponding Smart Link device. As shown in 

, all the devices including Switch C, 

Switch D, and Switch E on the active and backup links connecting the Smart Link device (Switch A) and 

the target uplink device (Switch E) are all associated devices. 

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 

, you need to enable this function on Ethernet 1/0/2 and Ethernet 1/0/3 of Switch C, Ethernet 1/0/2 

and Ethernet 1/0/3 of Switch D, and Ethernet 1/0/11 and Ethernet 1/0/12 of Switch E. 

Follow these steps to enable the specified port to process flush messages received from the specified 

control VLAN:

specified.  

 

When configuring Smart Link, pay attention to the following points: 

z 

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.  

z 

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.  

z 

A smart link/monitor link group with members cannot be deleted.  

z 

Smart Link/Monitor Link is mutually exclusive with remote port mirroring.  

z 

If you configure both the Smart Link and Monitor Link functions on an expandable resilient 

networking (XRN) enabled device, the Smart Link and Monitor Link functions will function 

abnormally. Thus, you are recommended to disable the XRN function when configuring the Smart 

Link or Monitor Link function.  

z 

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. 

z 

When you copy a port, the smart link/monitor link group member information configured on the port 

will not be copied to other ports.  

z 

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.
