2) Configure Device B
Follow the same configuration procedure performed on Device A to configure Device B.
Layer 2 Dynamic Aggregation Configuration Example
Network requirements
As shown in Figure 2-2, Device A and Device B are connected through their respective Ethernet ports
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) Configure Device A
# Configure the device to perform load sharing based on source and destination MAC addresses for
link aggregation groups.

# Create a Layer 2 aggregate interface Bridge-Aggregation 1 and configure the interface to work in
dynamic aggregation mode.
