AT-S67 and AT-S68 User’s Guide

Increased

Security

VLANs provide additional security not available in a shared media

network environment. Because a switched network only delivers frames

to intended recipients, and only broadcast frames to other members of

the VLAN, a network administrator can segment users requiring access

to sensitive information into separate VLANs from the rest of the general

user community.

Since data traffic generated by an end-node in a VLAN is restricted only

to the other end-nodes of the same VLAN, VLANs can be used to control

the flow of data in your network. It can also prevent data from flowing to

unauthorized end-nodes.
