Netgear FS526Tv2 - 24-Port Smart Switch with Gigabit Ports Guia Do Utilizador

Adding virtual LAN (VLAN) support to a Layer 2 switch provides 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, you can group 
users 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 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 port can handle traffic for multiple VLANs, 
but it can support only one default VLAN ID.

For more information about VLANs, including configuration 
examples, see 

The smart switch supports up to 128 VLANs. VLAN 1 is the preconfigured default VLAN, and 
all port are untagged members by default. VLAN

 

2 (VoiceVLAN) and VLAN 3 (Auto-Video) 

are also preconfigured VLANs, but no ports are part of these VLANs by default. You cannot 
delete VLAN 1, VLAN 2, or VLAN 3.

By default, all ports are untagged members of VLAN 1, the default 
VLAN. However, ports that you make members of link aggregation 
groups (that is, physical interfaces that function as trunk members) 
lose their membership of the default VLAN. For more information 
about link aggregation groups, see
