ONFIGURATION

Switch A connects switch B with three aggregation ports, numbered as 
GigabitEthernet2/1/1 to GigabitEthernet2/1/3, so that the incoming and outgoing 
loads can be balanced among the member ports.

Figure 2   Networking For Link Aggregation

The following code example lists only the configuration for switch A. The 
configuration for switch B is similar.
