VLAN
To define a VLAN group, click Define VLAN Group in the VLAN
menu to access the VLAN Group Setting menu.
Make the desired VLAN Group assignment and tagging settings in
the window above and then click the SAVE button.
Up to eight VLAN groups may be created. Click to select the
Ethernet Port and ATM VCs Port for each VLAN member port. Any
port may be specified as Tagged.
Packets that are tagged (are carrying the 802.1Q VID information)
can be transmitted from one 802.1Q compliant network device to
another with the VLAN information intact. This allows 802.1Q VLANs
to span network devices (and indeed, the entire network, if all
network devices are 802.1Q compliant).
Select the Tagged option to enable tagging for the port. Ports with
tagging enabled will put the VID number, priority and other VLAN
information into the header of all packets that flow into and out of it. If
a packet has previously been tagged, the port will not alter the
packet, thus keeping the VLAN information intact. Other 802.1Q
compliant devices on the network to make packet-forwarding
decisions can then use the VLAN information in the tag.
