Section 1. Implementing VLANS and Trunks
The virtual LAN (VLAN) organizes physically separate users into the same broadcast domain. The use of VLANs improves performance, security, and flexibility. The use of VLANs also decreases the cost of arranging users, because no extra cabling is required.
VLANs allow logically defined user groups rather than user groups defined by their physical locations. For example, you can arrange user groups such as accounting, engineering, and finance, rather than everyone on the first floor, everyone on the second floor, and so on.
• VLANs define broadcast domains that can span multiple LAN segments.

• VLAN segmentation is not bound ...
