Adding Virtual Circuits To An Adsl Interface; Vpi/Vci And Multiplexing Method - Juniper Networks NetScreen-5GT Wireless Manual Del Usuario

Adding Virtual Circuits to an ADSL Interface

To add virtual circuits, you create subinterfaces to the ADSL interface. You can create up
to 10 ADSL subinterfaces. For example, to create a new subinterface named adsl1.1 that
is bound to the user-defined zone named "Corp1":
WebUI
Network > Interfaces > New ADSL Sub-IF: Enter the following, and then click
Apply:
Interface Name: adsl1.1
VPI/VCI: 0/35
Zone Name: Corp1 (select)
CLI
set interface adsl1.1 pvc 0 35 zone corp1
save
You need to configure an ADSL subinterface in the same way as the main ADSL interface,
including setting the VPI/VCI values, as described in
on page 20. You configure an ADSL subinterface independently of the main ADSL
interface; that is, you can configure a different multiplexing method, VPI/VCI, and PPP
client on the subinterface than the main ADSL interface. You can also configure a static
IP address on a subinterface, even if the main ADSL interface does not have a static IP
address. Note that a subinterface and the main ADSL interface can use the same VPI/VCI
values if one interface is configured for PPPoA and the other for PPPoE and they both use
LLC multiplexing.

VPI/VCI and Multiplexing Method

Your service provider assigns a VPI/VCI pair for each VC connection. For example, you
may receive the VPI/VCI pair 1/1, which means a VPI value of 1 and a VCI value of 1.
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 1/1 on the adsl1 interface:
WebUI
Network > Interfaces > Edit (for the adsl1 interface): Enter 1/1 in the VPI/VCI
field, and then click Apply.
CLI
set interface adsl1 pvc 1 1
save
By default, the NetScreen-5GT Wireless ADSL device uses LLC-based multiplexing for
each VC. To configure the VPI/VCI 1/1 on the adsl1 interface and use LLC encapsulation
on the VC:
