Configuration procedure
1. Configure Device A:
# Create VLAN 10, and assign the port GigabitEthernet 4/0/4 to VLAN 10.
<DeviceA> system-view
[DeviceA] vlan 10
[DeviceA-vlan10] port gigabitethernet 4/0/4
[DeviceA-vlan10] quit
# Create VLAN 20, and assign the port GigabitEthernet 4/0/5 to VLAN 20.
[DeviceA] vlan 20
[DeviceA-vlan20] port gigabitethernet 4/0/5
[DeviceA-vlan20] quit
# Create Layer 2 aggregate interface Bridge-Aggregation 1, and configure the link aggregation
mode as dynamic.
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] link-aggregation mode dynamic
# Assign ports GigabitEthernet 4/0/1 through GigabitEthernet 4/0/3 to link aggregation group
1.
[DeviceA] interface gigabitethernet 4/0/1
[DeviceA-GigabitEthernet4/0/1] port link-aggregation group 1
[DeviceA-GigabitEthernet4/0/1] quit
