Vlan Configuration - Planet WGSD-1022 User Manual

4.4 VLAN Configura tion
A Virtual LAN (VLAN) is a logical n etwork grouping that limits the broadcast domain. It a llows you to
isolate net work traffic so onl y mem bers of the VLAN receiv e traffic from the same VLAN members.
Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network
devices t o anothe r Layer 2 switch . However, all the network devices are still plug into the same switch
physically.
The WGSD-1022 supports 802.1Q (tagged-based) and GVRP Dynamic VLAN setting in web
manageme nt page. In the def ault configuration, VLAN support is "802.1Q".
IEEE 802.1Q VLANs
IEEE 802.1Q (tagged) VLAN are implemented on the Switch. 802.1Q VLAN require tagging, which
enables them to span the entire network (assuming all switches on the network are IEEE
802.1Q-compliant).
VLAN allow a network to be segmented in order to reduce the size of broadcast domains. All packets
entering a VLAN will only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are
members of that VLAN, and this includes broadcast, multicast and unicast packets from unknown
sources.
VLAN can also provide a level of security to your network. IEEE 802.1Q VLAN will only deliver packets
between stations that are members of the VLAN. Any port can be configured as either tagging or
untagging. The untagging feature of IEEE 802.1Q VLAN allows VLAN to work with legacy switches that
don't recognize VLAN tags in packet headers. The tagging feature allows VLAN to span multiple
802.1Q-compliant switches through a single physical connection and allows Spanning Tree to be enabled
on all ports and work normally.

Frame Income
Income Frame is tagged Income Frame is untagged
Frame Leave
Leave port is tagged Frame remains tagged Tag is inserted
Leave port is untagged Tag is removed Frame remain untagged
