VLAN

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® VGx- 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
