following configuration on Switch A. The configuration on Switch B is the same as on Switch A. 
# Enter system view.  
<switchA> system-view 
# Enter Ethernet port view. Disable STP on GigabitEthernet1/0/1 and GigabitEthernet1/0/2. 
[SwitchA] interface GigabitEthernet 1/0/1 
[SwitchA-GigabitEthernet1/0/1] stp disable 
[SwitchA-GigabitEthernet1/0/1] quit 
[SwitchA] interface GigabitEthernet 1/0/2 
[SwitchA-GigabitEthernet1/0/2] stp disable 
# Return to system view. 
[SwitchA-GigabitEthernet1/0/2] quit 
# Create smart link group 1 and enter smart link group view. 
[SwitchA] smart-link group 1 
# Configure GigabitEthernet 1/0/1 as the master port of the smart link group and GigabitEthernet 1/0/2 
as the slave port.  
[SwitchA-smlk-group1] port GigabitEthernet 1/0/1 master 
[SwitchA-smlk-group1] port GigabitEthernet 1/0/2 slave 
# Configure to send flush messages in VLAN 1. 
[SwitchA-smlk-group1] flush enable control-vlan 1
