Enable the function of sending 
flush messages in the specified 
control VLAN 

flush enable control-vlan 
vlan-id 

Optional 

By default, no control VLAN for 
sending flush messages is 
specified.  

 

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 GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 of Switch C, 

GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 of Switch D, and GigabitEthernet 1/0/11 and 

GigabitEthernet 1/0/12 of Switch E. 

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

control VLAN:

Required, use 
either 
approach. 

By default, no 
control VLAN 
for receiving 
flush messages 
is 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 

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.
