VLAN Configuration
Overview
In large networks, routers are used to isolate broadcast traffic for each
subnet into separate domains. This switch provides a similar service 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.
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 provide a high level of network security
since traffic must pass through a Layer 3 switch to reach a different VLAN.
This switch supports the following VLAN features:
• Port-based VLANs for isolating user groups or subnets
• IEEE 802.1Q tagged VLANs that can span across the network
(Up to 128 VLANs based on the IEEE 802.1Q standard)
• Distributed VLAN learning across multiple switches using tagging and
GVRP dynamic registration protocol
• Port overlapping, allowing a port to participate in multiple VLANs
