2) Configure Device B
Follow the same configuration procedure performed on Device A to configure Device B.
Layer 2 Aggregation Load Sharing Mode Configuration Example
Network requirements
As shown in Figure 1-4, Device A is connection to Device B by their Ethernet ports GigabitEthernet
2/0/1 through GigabitEthernet 2/0/4.
Configure the global load sharing mode and aggregation group-specific load sharing mode to enable
aggregation group 1 to use source MAC-based load sharing mode and aggregation group 2 to use
destination MAC-based load sharing mode.
