Configuration procedure
1) VLAN and VLAN member port configuration
Create VLAN 10, VLAN 20, and VLAN 30 on Device A and Device B respectively, create VLAN 10,
VLAN 20, and VLAN 40 on Device C, and create VLAN 20, VLAN 30, and VLAN 40 on Device D;
configure the ports on these devices as trunk ports and assign them to related VLANs. The detailed
