Configuring Your SmartRG

™

- Common Use Cases

To simplify your deployment of SmartRG gateways this document is structured around specific use

cases designed to illustrate meaningful, service supporting configurations like:



Creating WAN interfaces for Internet data access and remote gateway management



Provisioning the SmartRG for remote management via TR-069



Setting up the LAN



Managing wireless



Creating IPTV service configurations (bridged and routed)



Classifying LAN traffic and applying QoS to support IPTV and VoIP applications



Enabling secure communications (IPSec)

Given the breadth of a SmartRG residential gateway

’s features and the

diversity of applications,

only the most common use cases are detailed here. Please contact SmartRG Support to inquire

about additional use cases.

Use Case: Creating WAN Connections for Internet Access and Remote

Management

SmartRG residential gateways are commonly deployed to provide Internet access for LAN hosts

such as workstations, gaming consoles, IP cameras and myriad other IP enabled devices

increasingly found in the home or office. Packets routed between LAN hosts and the Internet pass

through the gate

way’s routed

WAN connection. Remote management (via TR-069) is also

performed through this connection. The typical Internet access/remote management connection

configuration is diagramed below.

Figure 9 Internet / TR-069 Management WAN Connection

WAN connection creation is a two-step process beginning with the configuration of a layer 2

interface (Ethernet or DSL) followed by the creation of a layer 3, WAN service. Common WAN

services include PPPoE, DHCP and Static IP.

Configuring the Layer 2 Interface (Ethernet)

To configure an Ethernet layer 2 interface:

1.

Select

Advanced Setup -> Layer2 Interface.

The default Ethernet WAN interface

(eth0.5/LAN4) will be displayed.

Figure 10 Ethernet Layer 2 Interface Configuration (Default)

No further configuration is necessary.

Configuring the Layer 2 Interface (Ethernet with VLAN Tags)

In some applications it may be necessary to segment the Ethernet WAN interface into separate

VLANs. A common application for a VLAN segmented WAN interface is bridged IPTV as detailed in

the

“

Bridged IPTV Configuration

”

section. To configure the layer 2 Ethernet interface to support

VLAN tagged traffic:

1.

Select

Advanced Setup -> Layer2 Interface.

The default Ethernet WAN interface

(eth0.5/LAN4) will be displayed.

2.

Check the “Remove” box and click

Remove.

3.

Click Add.

4.

Select “VLAN MUX Mode.”

5.

Click Apply/Save.

NOTE

802.1P (priority) and 802.1Q (VLAN tag) values will be set at the time of WAN Service

creation as detailed in, “

Creating the WAN Service

.”

Configuring the Layer 2 Interface (ADSL)

To configure an ADSL layer 2 interface:

1.

Select

Advanced Setup -> Layer2 Interface

and click Add.

Figure 12 ADSL Layer 2 Interface Configuration

2.

Enter the PVC’s identifier (VPI/VCI)

.

3.

Select the

“

DSL Link Type

”

–

Ethernet over ATM (RFC 2684) is typical.

4.

Select the

“

Encapsulation Mode

”

–

LLC/SNAP-BRIDGING is typical.

5.

Select the

“

Service Category

”

(upstream ATM shaping)

–

“

UBR Without PCR

”

(Unspecified

Bit Rate Without Peak Cell Rate) is typical.

6.

Select the

“

Connection Mode

”

–

Choose Default Mode for non-VLAN tagged traffic. Choose

VLAN MUX Mode if you intend to segment LAN traffic into separate VLAN tagged WAN

services.

IMPORTANT

- Check

“

Enable Quality of Service

”

if you intend to support QoS classified

traffic through the WAN service.

8.

Click Apply/Save.

NOTE

Enabling QoS for routed IPTV service configurations will improve channel change

performance.

Configuring the Layer 2 Interface (VDSL/PTM)

To configure a VDSL / PTM layer 2 interface:

1.

Select

Advanced Setup -> Layer2 Interface -> PTM Interface

and click Add.

Figure 13 VDSL Layer 2 Interface Configuration

2.

Select the “DSL

Latency

” –

Path0 is typical.

3.

Select the “

PTM Priority

” –

Normal Priority is typical.

4.

Select the “

Connection Mode

” –

Default Mode is typical (when VLAN segmentation is not

required).

5.

IMPORTANT

-

Check “Enable Quality of Service” if you intend to support QoS classified

traffic through the WAN service.
