VLAN Configuration

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.
Beginning with Version 8.7.4, VLANs are now 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 in 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
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:
•
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
- LAN-side VLAN with IP interface-to-VLAN binding
- Inter-VLAN routing groups to extend VLAN segmentation up through the IP routing layer.
•
Bridged VLANs - these VLANs are used to bridge traffic from LAN to WAN
•
Prioritization per VLAN and per port
