SSG 20 Hardware Installation and Configuration Guide

Virtual Circuits

To add virtual circuits, you create subinterfaces to the ADSL2/2+ interface. You can create up to 10 ADSL2/2+ subinterfaces. For example, to create a new subinterface named adsl1/0.1 bound to the predefined zone named Untrust, use the WebUI or CLI as follows:

WebUI

Network > Interfaces > List > New ADSL Sub-IF: Enter the following, then click Apply:

Interface Name: adsl1/0.1

VPI/VCI: 0/35

Zone Name: Untrust (select)

CLI

set interface adsl 1/0.1 pvc 0 35 zone Untrust save

You need to configure an ADSL 2/2+subinterface in the same way as the main ADSL2/2+ interface, including setting the VPI/VCI values, as described in “ADSL2/2+ Interface” on page 41. You configure an ADSL2/2+ subinterface independently of the main ADSL2/2+ interface; that is, you can configure a different multiplexing method, VPI/VCI, and PPP client on the subinterface than on the main ADSL2/2+ interface. You can also configure a static IP address on a subinterface, even if the main ADSL2/2+ interface does not have a static IP address.

VPI/VCI and Multiplexing Method

Your service provider assigns a VPI/VCI pair for each virtual-circuit connection. For example, you may receive the VPI/VCI pair 1/32, which means a VPI value of 1 and a VCI value of 32. These values must match the values that the service provider has configured on the subscriber’s side of the Digital Subscriber Line Access Multiplexer (DSLAM).

To configure the VPI/VCI pair 1/32 on the adsl1/0 interface, use the WebUI or CLI as follows:

WebUI

Network > Interfaces > List > Edit (for the adsl1/0 interface): Enter 1/32 in the VPI/VCI field, then click Apply.

CLI

set interface adsl1/0 pvc 1 32 save

By default, the device uses Logical Link Control (LLC)-based multiplexing for each virtual circuit.

To configure the VPI/VCI 1/32 on the adslx/0 interface and use LLC encapsulation on the virtual circuit, use the WebUI or CLI as follows:
