Creating Vendor ID Based Interface (Bridge) Groupings

To provide greater flexibility when connecting set-top-boxes to LAN ports SmartRG gateways

support “Vendor ID Based” bridge groupings

. Instead of adding specific LAN ports to the bridge

group, you can specify the Vendor ID of the set-top-box. Any traffic received on any LAN port

containing the specified Vendor ID will be bridged to the designated bridged WAN connection.

To configure Vendor ID based interface groupings, add only the WAN interface(s) to the bridge

group and then specify the required Vendor ID(s) in the following list:

Routed IPTV Configuration (Single WAN Connection)

The common routed IPTV configuration is virtually identical to the WAN connection configuration

for Internet data services with one notable exception; the addition of quality of service (QoS).

While not an absolute requirement, applying QoS to LAN traffic (with higher priority given to STBs)

ensures the timely and deterministic delivery of IPTV related uni-cast requests and IGMP signaling

through the gateway. This provides repeatable, shortest time possible channel changes in the

presence of other LAN traffic. A typical routed IPTV service configuration with only one WAN

connection is shown below.

Figure 36 Routed IPTV Configuration (Single WAN Connection)

To configure the SmartRG for routed IPTV service deployments:

1.

Ensure “IGMP Snooping” has been enabled on the LAN as detailed in, “

Use Case: Setting Up

the LAN

.”

2.

Create a routed WAN connection as detailed

in, “

Use Case: Creating WAN Connections for

Internet Access and Remote Management

.”

3.

(Optional) Create traffic classifiers and priority queues for the various traffic categories on

your LAN (e.g. Internet data, IPTV and VoIP) as detailed in, “

Use Case: Applying Quality of S

.”

NOTE

The SmartRG family of gateways employs “Differentiated Services” (RFC

2474) to

provide IP traffic QoS. When configuring QoS for various traffic categories the following

Differentiated Services Code Point (DSCP) values or suggested:



Internet data

–

Best Effort (DSCP 0)



IPTV

–

AF21 (DSCP 18)



VoIP

–

Expedited Forwarding (DSCP 46)

NOTE

Some STBs pre-mark their IP traffic making classification a relatively straightforward

task for the gateway. If your STB pre-marks its traffic, passing the DSCP mark through
