VLAN Configuration
Overview
A Vir tual 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 ver y flexible. VLANs
behave like separate and independent networks.

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 vir tual Ethernet
switches, into which can be added: Ethernet por ts, router IP inter faces, ATM PVC/VCC inter faces, SSIDs, and
any other physical por t such as USB, HPNA, or MOCA. This allows great flexibility in how the components of a
system are connected to each other.

VLANs are par t of Motorola’s VGx Vir tual Gateway technology which allows individual por t-based VLANs to be
treated as separate and distinct “channels.” When data is passed to a Motorola Netopia

Your Gateway suppor ts the following:
•
Global VLANs - these are used when trunking/tagging is required on any por t 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.

- Suppor ts 802.1q and 802.1p; both are configurable
•
Por t-based VLANs - these can be used when no trunking is required
•
Routed VLANs
- WAN-side VLAN with Multiple WAN IPoE/PPPoE inter face suppor t and IP inter face-to-VLAN binding
- LAN-side VLAN with IP inter face-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 por t
