 Receiving interface of the last flush packet       : GigabitEthernet2/0/3 

 Receiving time of the last flush packet            : 16:25:21 2009/02/21 

 Device ID of the last flush packet                 : 000f-e23d-5af0 

 Control VLAN of the last flush packet              : 1 

As shown in 

z 

Traffic of VLANs 1 through 200 on Device C are dually uplinked to Device A by Device B and 

Device D. Implement load sharing to uplink the traffic of VLANs 1 through 100 and the traffic of 

VLANs 101 through 200 over different links to Device A.  

z 

Implement dual uplink backup on Device C: traffic of VLANs 1 through 100 (mapped to MSTI 0) is 

uplinked to Device A by Device B; traffic of VLANs 101 through 200 (mapped to MSTI 2) is uplinked 

to Device A by Device D. Smart link group 1 references MSTI 0, and smart link group 2 references 

MSTI 2.  

z 

The control VLAN of smart link group 1 is VLAN 10 and that of smart link group 2 is VLAN 101.
