1.2.11 VLAN
The virtual LAN (VLAN) allows you to group physically separate users into the same broadcast
domain. The use of VLANs improves security, segmentation, and flexibility. The use of VLANs also
decreases the cost of arranging users, because no extra cabling is required.
VLANs allow an administrator to define user groups logically rather than by their physical locations.
For example, you can arrange user groups such as accounting, engineering, and finance rather than
grouping 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 by the physical location of users.
 Each switch port can be assigned to only one VLAN.
 Ports not assigned to the same VLAN do not share broadcasts, improving network
performance.
 A VLAN can exist on one switch or on multiple switches.
 VLANs can connect across wide-area networks (WANs). The figure shows a VLAN design.
VLANs are defined by user functions rather than locations.
Each VLAN on a switch behaves as if it were a separate physical bridge. The switch forwards packets
(including unicasts, multicasts, and broadcasts) only to ports assigned to the same VLAN from which
it originated. This reduces on network traffic. VLANs require a trunk to span multiple switches. Each
trunk can carry traffic for multiple VLANs.
1.2.11-1 VLAN Membership
This section is used to configure VLAN settings on the APS Series switches. Here you can create
VLAN’s and assign ports into specific VLAN groups. The maximum n umber of VLAN groups that can
be created is 4096.
Web Interface
To configure the VLAN settings via the Web Interface:
1. Click Configuration, VLAN and VLAN Membership.
2. Click Add New VLAN to add additional VLAN groups.
3. Give the VLAN group a name and assign a VLAN ID (2 – 4096) for the group.
4. Click the Apply button to save your changes or the Reset button to revert to previous
settings.
