Chapter 2 Configuring the Device
• User name and password assigned by the service provider for connection to the
service provider's network using either the 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
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 1/1, 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 ADSL device uses VC-based multiplexing for each virtual
circuit. To configure the VPI/VCI 1/1 on the adsl1 interface and use LLC encapsulation on
the virtual circuit:
WebUI
Network > Interfaces > Edit (for the adsl1 interface): Enter the following, and then
click Apply:
VPI/VCI: 1 / 2
Multiplexing Method: LLC (select)
CLI
set interface adsl1 pvc 1 1 mux llc
save
PPPoE or PPPoA
The NetScreen device includes both PPPoE and PPPoA clients to connect to the service
provider's network over the ADSL link. PPPoE is the most common form of ADSL
encapsulation and is intended for termination on each host on your network. PPPoA is
used primarily for business class service as PPP sessions can be terminated on the
NetScreen device. To allow the NetScreen device to connect to the service provider's
network, you need to configure the user name and password assigned by the service
provider. The configuration for PPPoA is similar to the configuration for PPPoE.
Note: The NetScreen device supports only one PPPoE session on each virtual circuit.
