Control VLAN of the last flush packet : 1
Multiple Smart Link Groups Load Sharing Configuration Example
Network requirements
As shown in Figure 1-3:
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.
