Layer 2 Dynamic Aggregation Configuration Example

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.

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 a Layer 2 aggregate interface Bridge-Aggregation 1 and configure the interface to work in
dynamic aggregation mode.
[DeviceA] interface bridge-aggregation 1
[DeviceA-Bridge-Aggregation1] link-aggregation mode dynamic
[DeviceA-Bridge-Aggregation1] quit
# Assign Layer 2 Ethernet interfaces GigabitEthernet 1/0/1 through GigabitEthernet 1/0/3 to
aggregation group 1.
[DeviceA] interface GigabitEthernet 1/0/1
[DeviceA-GigabitEthernet1/0/1] port link-aggregation group 1
[DeviceA- GigabitEthernet1/0/1] quit
