C HAPTER 4 | Configuring the Switch
IEEE 802.1Q VLANs
– 169 –
since traffic must pass through a configured Layer 3 link to reach a
different VLAN.
This switch supports the following VLAN features:
◆ Up to 256 VLANs based on the IEEE 802.1Q standard
◆ Distributed VLAN learning across multiple switches using explicit or
implicit tagging
◆ Port overlapping, allowing a port to participate in multiple VLANs
◆ End stations can belong to multiple VLANs
◆ Passing traffic between VLAN-aware and VLAN-unaware devices
◆ Priority tagging
Assigning Ports to VLANs
Before enabling VLANs for the switch, you must first assign each port to
the VLAN group(s) in which it will participate. By default all ports are
assigned to VLAN 1 as untagged ports. Add a port as a tagged port if you
want it to carry traffic for one or more VLANs, and any intermediate
network devices or the host at the other end of the connection supports
VLANs. Then assign ports on the other VLAN-aware network devices along
the path that will carry this traffic to the same VLAN(s), either manually or
dynamically using GVRP. However, if you want a port on this switch to
participate in one or more VLANs, but none of the intermediate network
devices nor the host at the other end of the connection supports VLANs,
then you should add this port to the VLAN as an untagged port.

Use the VLAN Membership Configuration page to enable VLANs for this
switch by assigning each port to the VLAN group(s) in which it will
participate.

These parameters are displayed:
◆ VLAN ID - VLAN Identifier. (Range: 1-4095)
◆ VLAN Name - The name of a VLAN. (Range: 1-32 alphanumeric
characters)
◆ Port Members - Port identifier.
Port overlapping can be used to allow access to commonly shared
network resources among different VLAN groups, such as file servers or
printers. Note that if you implement VLANs which do not overlap, but
still need to communicate, you must connect them through a router.
