4.2.2.4.6. VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only
members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically equivalent
of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plug into the same
switch physically. A screen is displayed as shown in
Figure 4.2.2.4.7
.
The HPNA SWITCH support port-based and protocol-base VLAN in web management page, In the default configuration, VLAN
support is enable and all ports on the switch belong to default VLAN, VID is 1.
Support Tagging-based VLANs (IEEE 802.1Q VLAN)
Port-based Tagging rule VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices
from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag contains a VLAN
Identifier (VID) that indicates the VLAN numbers.
Support Protocol-based VLAN
In order for an end station to send packets to different VLANs, it itself has to be either capable of tagging packets it sends with VLAN
tags or attached to a VLA N-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not
only default PVID but also other information about the packet, such as the protocol.
HPNA IP DSLAM will support protocol-based VLAN classification by means of both built-in knowledge of layer 2 packet formats used
by selected popular protocols, such as Novell IPX and AppleTalk’s EtherTalk, and some degree of programmable protocol matching
capability.
