The output shows that all link aggregation groups created on the device perform load sharing based on
source and destination MAC addresses.
Layer 2 dynamic aggregation configuration example
Network requirements
As shown in Figure 37 :
• Configure a Layer 2 dynamic link aggregation group on both Device A and Device B, 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.
