tion parameters can be applied to each individual service, delivering that service to the
appropriate peripheral 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 maps multiple local VLANs to one or more specific permanent
virtual circuits (PVCs) for DSL, or wide area network VLANs for a fiber network. VGx pro-
vides service segmentation and QoS controls, service management, and supports delivery
of triple play applications: voice for IP Telephony, video for IPTV, and data.
Your Gateway supports the following:
• Port-based VLANs - these can be used when no trunking is required
• Global VLANs - these are used when trunking is required on any port member of the
VLAN
- Supports 802.1q and 802.1p; both are configurable
•
Routed VLANs
- WAN-side VLAN with Multiple WAN IPoE interface support and IP interface-to-VLAN
binding
- LAN-side VLAN with IP interface-to-VLAN binding
- Inter-VLAN routing
•
Bridged VLANs - these VLANs are used to bridge traffic from LAN to WAN
• Prioritization per VLAN and per port
Ethernet Switching/Policy Setup
Before you configure any VLANs, the unconfigured Gateway is set up as a router composed
of a LAN switch, a WAN switch, and a router in the middle, with LAN and WAN IP interfaces
connected to their respective switches. These bindings between Ethernet switch ports, IP
LAN interface, IP WAN interface and WAN physical ports are automatically created.
When you configure any VLANs, the default bindings are no longer valid, and the system
requires explicit binding between IP interfaces and layer 2 interfaces. Each VLAN can be
thought of as a layer 2 switch, and enabling each port or interface in a VLAN is analogous
to plugging it in to the layer 2 switch.
Thereafter, in order for devices to communicate on layer 2, they must be associated in the
same VLAN. For devices to communicate at layer 3, the devices must be either on the
same VLAN, or on VLANs that have an Inter-VLAN routing group enabled in common.
