The switch supports Tag-based VLAN (802.1Q) and Port-based VLAN.
Support 4094 active VLANs and VLAN ID 1~4094. VLAN configuration
is used to partition your LAN into small ones as your demand. Properly
configuring it, you can gain not only improving security and increasing
performance but greatly reducing VLAN management. 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 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.
