You can use the
display smart-link flush
command to display the flush messages received on each
device. For example:
# Display the flush messages received on Device B.
[DeviceB] display smart-link flush
Received flush packets : 5
Receiving interface of the last flush packet : GigabitEthernet1/0/3
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
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.
