Trunk Vlan Setting - NetComm IP DSLAM NCT480 User Manual

Trunk vLAN Setting

The trunk VLAN setting dialog list the existing trunk VLAN and its configuration.
A VLAN allows a physical network to be divided into several logical networks. A device can belong to more
than one VLAN group. Devices that are not in the same VLAN groups can not talk to each other. VLAN can
provide isolation and security to users and increase performance by limiting broadcast domain. VLAN tag
can be added to the MAC header to identify the VLAN membership of a frame across bridges. A tagged
frame is four bytes longer than an untagged frame. Each port of NCT480 is capable of passing tagged or
untagged frames.
Click 'Add' button to set the new trunk VLAN with associate port interface.
