6.10 IEEE 802.1Q VLANS
In large networks, routers are used to isolate broadcast traffic for each subnet into separate
domains. This switch provides a similar service at Layer 2 by using VLANs to organize any group
of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the
originating group, and can eliminate broadcast storms in large networks. This also provides a
more secure and cleaner network environment.
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.
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
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
