VLANs
Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both 
bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 
header, which is fast, and like a router, it partitions the network into logical segments, which 
provides better administration, security and management of multicast traffic.
By default, all ports on the switch are in the same broadcast domain. VLANs electronically 
separate ports on the same switch into separate broadcast domains so that broadcast 
packets are not sent to all the ports on a single switch. When you use a VLAN, users can be 
grouped by logical function instead of physical location.
Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag 
in the Layer 2 header of packets transmitted on a VLAN. An end station may omit the tag, or 
the VLAN portion of the tag, in which case the first switch port to receive the packet may 
either reject it or insert a tag using its default VLAN ID. A given port may handle traffic for 
more than one VLAN, but it can only support one default VLAN ID.
From the VLAN link, you can access the following pages:
VLAN Configuration
Use the VLAN Configuration page to define VLAN groups stored in the VLAN membership 
table. The GS716T and GS724T support up to 64 VLANs. VLAN 1 is created by default, and 
all ports are untagged members.
