When you click VLAN, the VLANs page appears.

Overview

A Virtual Local Area Network (VLAN) is a network of computers or other devices that behave as if they
are connected to the same wire even though they may be physically located on different segments of a
LAN. You set up VLANs by configuring the Gateway software rather than hardware. This makes VLANs
very flexible. VLANs behave like separate and independent networks.
VLANs are strictly layer 2 entities. They can be thought of as virtual Ethernet switches, into which can
be added: Ethernet ports, router IP interfaces, ATM PVC/VCC interfaces, SSIDs, and any other physical
port such as USB, HPNA, or MOCA. This allows great flexibility on how the components of a system are
connected to each other.
VLANs are part of Motorola's VGx Virtual Gateway technology which allows individual port-based VLANs
to be treated as separate and distinct "channels." When data is passed to a Motorola Netopia
enabled broadband gateway, specific policies, routing, and prioritization parameters can be applied to
each individual service, delivering that service to the appropriate networked device with the required
level of quality of service (QoS). In effect, a single Motorola gateway acts as separate virtual gateways
for each distinct service being delivered.
Motorola's VGx technology provides service segmentation and QoS controls, and supports delivery of
triple play applications: voice for IP Telephony, video for IPTV, and data.
Your Gateway supports the following:
❑ VLAN management access restriction.
❑ Global VLANs - these are used when trunking/tagging is required on any port member of the VLAN.
Trunks are used to interconnect switches to form networks. The VLANs can communicate with each
other via a trunking connection between the two switches using the router.
❑ - Supports 802.1q and 802.1p; both are configurable
❑ Port-based VLANs - these can be used when no trunking is required
❑ Routed VLANs
- WAN-side VLAN with Multiple WAN IPoE/PPPoE interface support and IP interface-to-VLAN binding
