MAC Address: Specify a destination MAC address in the packet.
VID: Specify the VLAN where the packets with the Destination MAC address can be
forwarded.
Forwarding Port: If the incoming packet has the same destination MAC address as the one
specified in VID, it will be forwarded to the selected port directly.
4.4.7 VLAN Configuration
A Virtual Local Area Network (VLAN) is a network topology configured according to a logical
scheme rather than the physical layout. VLAN can be used to combine any collections of
LAN segments into a group that appears as a single LAN. VLAN also logically segments the
network into different broadcast domains. All broadcast, multicast, and unknown packets
entering the Switch on a particular VLAN will only be forwarded to the stations or ports that
are members of that VLAN.
VLAN can enhance performance by conserving bandwidth and improve security by limiting
traffic to specific domains. A VLAN is a collection of end nodes grouped by logics instead of
physical locations. End nodes that frequently communicate with each other are assigned to
the same VLAN, no matter where they are physically located on the network. Another
benefit of VLAN is that you can change the network topology without physically moving
stations or changing cable connections. Stations can be „moved‟ to another VLAN and thus
communicate with its members and share its resources, simply by changing the port VLAN
settings from one VLAN to another. This allows VLAN to accommodate network moves,
changes and additions with the greatest flexibility.
The Managed Switch supports two types of VLAN, these are: Port-Based VLAN (26 sets)
and 802.1Q Tag VLAN (128 sets).
4.4.7.1 Port-Based VLAN
Port-based VLAN can effectively segment one network into several broadcast domains,
Broadcast/Multicast and unknown packets will be limited to within the VLAN. Port-Based
VLAN is uncomplicated and fairly rigid in implementation and is useful for network
administrators who wish to quickly and easily set up VLAN so as to isolate the effect of
broadcast packets on their network.
The following screen page appears when you choose Port-Based VLAN mode and then
select Configure VLAN.
