Mini PIM Configuration
„ 31
If you are using the ADSL2/2+ interface to connect to the service provider’s
network, you must configure the adsl(x/0) interface. To do this, you must obtain the
following information from your service provider:
„ Virtual Path Identifier and Virtual Channel Identifier (VPI/VCI) values
„ ATM Adaptation Layer 5 (AAL5) multiplexing method, which can be one of the
following:
„ Virtual Circuit-based multiplexing, in which each protocol is carried over a
separate ATM virtual circuit
„ Logical Link Control (LLC) encapsulation, which allows several protocols to
be carried on the same ATM virtual circuit (the default multiplexing
method)
„ Username and password assigned by the service provider for connection to the
service provider’s network using either Point-to-Point Protocol over Ethernet
(PPPoE) or Point-to-Point Protocol over ATM (PPPoA)
„ Authentication method, if any, provided for the PPPoE or PPPoA connection
„ Optionally, a static IP address and netmask value for your network
Virtual Circuits to an ADSL2/2+ Interface
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 user-defined zone named
Untrust :
WebUI
Network > Interfaces > New ADSL Sub-IF: Enter the following, click Apply :
Interface Name: adsl1/0.1
VPI/VCI: 8/35
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
“Connecting the ADSL2/2+ Mini PIM” on page 12. 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. Note that a subinterface and the main ADSL2/2+ interface have to
use the same VPI/VCI values if one interface is configured for PPPoA and the other
for PPPoE and they both use LLC multiplexing.
