26.3.1 Access and trunk ports

A port VLAN allocates a single VLAN to a single port. The ports used for a port VLAN are set as access ports. A trunk port is used to connect multiple port VLANs to other LAN switches. Because a trunk port uses VLAN tags to identify VLANs, multiple VLANs can be set for a single port.

The figure below shows an example port VLAN configuration. Ports 1/0/1 to 1/0/3 configure the port VLAN as an access port. These two Switches are connected by a trunk port (port 1/0/4). VLAN tags are used in this case.
