Layer 2 Dynamic Aggregation Configuration Example - H3C S5120-EI Series Operation Manual

Aggregate the ports on each device to form a static link aggregation group, thus balancing outgoing
traffic across the member ports. In addition, perform load sharing based on source and destination MAC
addresses.

Configuration procedure
1) Configure Device A
# Configure the device to perform load sharing based on source and destination MAC addresses for link
aggregation groups.
<DeviceA> system-view
[DeviceA] link-aggregation load-sharing mode source-mac destination-mac
# Create Layer 2 aggregate interface Bridge-aggregation 1.
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] quit
# Assign Layer 2 Ethernet interfaces GigabitEthernet1/0/1 through GigabitEthernet1/0/3 to aggregation
group 1.
[DeviceA] interface GigabitEthernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port link-aggregation group 1
[DeviceA-GigabitEthernet1/0/1] quit
[DeviceA] interface GigabitEthernet 1/0/2
[DeviceA-GigabitEthernet1/0/2] port link-aggregation group 1
[DeviceA-GigabitEthernet1/0/2] quit
[DeviceA] interface GigabitEthernet 1/0/3
[DeviceA-GigabitEthernet1/0/3] port link-aggregation group 1
2) Configure Device B
Follow the same configuration procedure performed on Device A to configure Device B.

Network requirements
As shown in Figure
GigabitEthernet1/0/1 to GigabitEthernet1/0/3.
Aggregate the ports on each device to form a dynamic link aggregation group, thus balancing outgoing
traffic across the member ports. In addition, perform load sharing based on source and destination MAC
addresses.
1-2, Device A and Device B are connected through their respective Ethernet ports
