Trendnet TEG-2248WS [7/46] Vlan virtual local area network

VLAN (Virtual Local Area Network)

A VLAN is a group of end-stations that are not constrained by their

physical location and can communicate as if a common broadcast

domain, a LAN. The primary utility of using VLAN is to reduce

latency and need for routers, using faster switching instead. Other

VLAN utility includes:

Security

Security is increased with the reduction of opportunity in

eavesdropping on a broadcast network because data will be switched

to only those confidential users within the VLAN.

Cost Reduction

VLANs can be used to create multiple broadcast domains, thus

eliminating the need of expensive routers.

Port-based (or port-group) VLAN is the common method of

implementing a VLAN, and is the one supplied in the Switch.

Limitations

TEG-2248WS has 2 port groups for VLAN settings which are

mutually exclusive. Ports from 1 through 24 are in one group and have

no limitations on the VLAN that can be set up within the group. Ports

from 25 to 52 are in the second group. Ports from group 1 cannot

belong to a VLAN with ports from group 2.
