Therefore, you must ensure that all member ports have the same port attributes andclass-two configurations as the reference port. The other settings only need to be configured on theaggregate interface, not on the member ports.Static Aggregation Configuration ExampleNetwork requirementsAs shown in Figure 1-4:z Device A and Device B are connected through their respective Layer 2 Ethernet interfacesGigabitEthernet 1/0/1 through GigabitEthernet 1/0/3.z Configure a Layer 2 static link aggregation group on Device A and Device B respectively , enableVLAN 10 at one end of the aggregate link to communicate with VLAN 10 at the other end, andVLAN 20 at one end to communicate with VLAN 20 at the other end.z Enable traffic to be load-shared across aggregation group member ports based on source anddestination MAC addresses.
