Aggregation Load Sharing Configuration Example
Network requirements
As shown in Figure 1-6:
z
Device A and Device B are connected by their Layer 2 Ethernet interfaces GigabitEthernet 1/0/1
through GigabitEthernet 1/0/4.
z
Configure two Layer 2 static link aggregation groups (1 and 2) on Device A and Device B
respectively, enable VLAN 10 at one end of the aggregate link to communicate with VLAN 10 at the
other end, and VLAN 20 at one end to communicate with VLAN 20 at the other end.
z
Configure the load sharing criterion for link aggregation group 1 as the source MAC addresses of
packets and the load sharing criterion for link aggregation group 2 as the destination MAC
addresses of packets to enable traffic to be load-shared across aggregation group member ports.

Configuration procedure
1) Configure Device A
# Create VLAN 10, and assign port GigabitEthernet1/0/5 to VLAN 10
<DeviceA> system-view
[DeviceA] vlan 10
[DeviceA-vlan10] port gigabitEthernet 1/0/5
[DeviceA-vlan10] quit
# Create VLAN 20, and assign port GigabitEthernet1/0/6 to VLAN 20.
[DeviceA] vlan 20
[DeviceA-vlan20] port gigabitEthernet 1/0/6
[DeviceA-vlan20] quit
# Create Layer 2 aggregate interface 1, and configure the load sharing criterion for the link aggregation
group as the source MAC addresses of packets.
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] link-aggregation load-sharing mode source-mac
[DeviceA-Bridge-Aggregation1] quit
# Assign ports GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to link aggregation group 1
。
[DeviceA] interface gigabitEthernet 1/0/1
