THE

An IEEE 802.1Q VLAN is a group of ports that can be located anywhere

in the network, but communicate as though they belong to the same

physical segment.

VLANs help to simplify network management by allowing you to move

devices to a new VLAN without having to change any physical

connections. VLANs can be easily organized to reflect departmental

groups (such as Marketing or R&D), usage groups (such as e-mail), or

multicast groups (used for multimedia applications such as

videoconferencing).

VLANs provide greater network efficiency by reducing broadcast traffic,

and allow you to make network changes without having to update IP

addresses or IP subnets. VLANs inherently provide a high level of network

security since traffic must pass through a configured Layer 3 link to reach a

different VLAN.

• Up to 255 VLANs based on the IEEE 802.1Q standard

• Distributed VLAN learning across multiple switches using explicit or

implicit tagging and GVRP protocol

• 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
