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.

ver y flexible. VLANs behave like separate and independent networks.
VLANs are 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 on 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:
❑ 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
