Tag-based:
Tag-based VLANs are identified by its VLAN ID or VID. Instead of filtering by port, all packets
coming into and out of the switch are filtered based on the VLAN ID in the packet, and are grouped
accordingly. The switch supports 802.1Q tag-based VLANs. Each tag-based VLAN must be assigned a
unique VLAN name and VLAN ID. Valid VLAN IDs range from 1 to 4094. Up to 64 VLAN tag groups can
be created.
Metro Mode:
Metro Mode is a quick configuration that creates 6 or 7 port-based VLAN groups (see below
for details).
Double-tag:
Double-tag mode is similar to tag-based mode, however it treats all frames as untagged
ones, which means that a PVID tag will be added to all packets. Then, these packets will be forwarded
using Tag-based VLAN rules. Thus, all incoming packets with tags will become the double-tag packets.

Up-link Port:
This section is only enabled when metro mode is chosen as the VLAN mode (Figure 3-27).
Possible options are:
7:
All ports can only transmit data to and from port 7. This effectively creates 7 port-based VLAN groups
between each port and port 7 (1 & 7, 2 & 7, 3 & 7, etc.)
8:
All ports can only transmit data to and from port 8. This effectively creates 7 port-based VLAN groups
between each port and port 8 (1 & 8, 2 & 8, 3 & 8, etc.)
7&8:
All ports can only transmit data to and from ports 7 and 8. This effectively creates 6 port-based
VLAN groups between each port and ports 7 and 8 (1 & 7 & 8, 2 & 7 & 8, 3 & 7 & 8, etc.)

3.10.2 Tag-based
Group
The Tag-based Group page (Figure 3-28) allows the user to create, edit, and delete Tag-based VLAN
groups. To delete a group, select the VLAN to delete and click the “Delete” button at the bottom of the
page.
