Netgear GS728TPP – 28PT GE POE+ SMART SWITCH Guia Do Administrador

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. 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 are 
grouped by logical function instead of physical location.

Each VLAN in a network has an associated VLAN ID, which displays in the IEEE 802.1Q tag 
in the Layer 2 header of packets transmitted on a VLAN. An end station might omit the tag, or 
the VLAN portion of the tag, in which case the first switch port to receive the packet can either 
reject it or insert a tag using its default VLAN ID. A given port can handle traffic for more than 
one VLAN, but it can support only one default VLAN ID.

From the VLAN menu, you can access the features described in the following sections:

Use the VLAN Configuration screen to define VLAN groups stored in the VLAN membership 
table. The switch supports up to 256 VLANs. VLAN 1 is created by default, and all ports are 
untagged members.
