Configuration Example
3.1 Network Requirements

Offices of both Department A and Department B in the company are located in different
places, and computers in different offices are connected to different switches.

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. Configure the
switch ports connected to the computers as Untagged. Then add the ports to the
corresponding VLANs.

The intermediate link between two switches carries traffic from two VLANs
simultaneously. Configure the ports on both ends of the intermediate link as Tagged,
and add the ports to both VLANs.
