VLAN Settings
This page allows you to create and delete VLANs (Virtual LANs) and to change the
VLAN membership and behaviour of individual ports. VLANs are powerful, but can
be difficult to set up properly. Each row of the table corresponds to one port or trunk;
trunked ports cannot be configured individually.
Introduction to VLANs
VLANs are logical partitions of the physical LAN. You can use VLANs to increase
network performance or improve internal network security.
If the network has adequate performance and security for your current needs, it is
recommended that you leave the VLAN settings in the default configuration. The
default configuration is as follows:
• All ports are members of VLAN 1
• The switch management interface is on VLAN 1 (this cannot be changed)
• All ports have a Port VLAN ID (PVID) of 1
• All ports can send and receive both VLAN-tagged and untagged packets (that is,
they are hybrid ports)
In the default configuration, any port is able to send traffic to any other port and a PC
connected to any port will be able to access the management interface. Broadcast
traffic, for example, will be flooded to all ports on the switch.
There are three different parameters that can be configured for each port on the
switch; VLAN ID (VLAN membership), PVID’s and Packet Type. Note that the ports
within a trunk cannot be configured individually; configure the trunk instead (trunks
are labelled T1 to T8).
IEEE 802.1Q Tunneling (QinQ) is designed for service providers carrying traffic for
multiple customers across their networks. QinQ tunneling is used to maintain
customer-specific VLAN configurations even when different customers use the
