5) Configuration on Device A
# Create VLANs 1 through 30.
<DeviceA> system-view
[DeviceA] vlan 1 to 30
# Configure GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3 as trunk ports that
permit VLANs 1 through 30 and enable flush message receiving on them.
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port link-type trunk
[DeviceA-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30
[DeviceA-GigabitEthernet1/0/1] smart-link flush enable
[DeviceA-GigabitEthernet1/0/1] quit
[DeviceA] interface gigabitethernet 1/0/2

6) Verifying the configurations
You can use the display smart-link group command to display the smart link group configuration on
each device. For example:
# Display the smart link group configuration on Device C.
[DeviceC] display smart-link group 1
Smart link group 1 information:
Device ID: 000f-e23d-5af0
Preemption mode: NONE
Control VLAN: 1
Protected VLAN: Reference Instance 0 to 2
Member Role State Flush-count Last-flush-time

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
