Configuration Example
3.1  Network Requirements
 ■ Offices of Department A and Department B in the company are located in different 
places, and some computers in different offices connect to the same switch.
 ■ It is required that computers can communicate with each other in the same department 
but not with computers in the other department.
3.2  Configuration Scheme
 ■ Divide computers in Department A and Department B into two VLANs respectively so 
that computers can communicate with each other in the same department but not with 
computers in the other department.
 ■ Terminal devices like computers usually do not support VLAN tags. Add untagged ports 
to the corresponding VLANs and specify the PVID.
 ■ The intermediate link between two switches carries traffic from two VLANs 
simultaneously. Add the tagged ports to both VLANs.
