Mini PIM Configuration
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:
WebUI
Network > Interfaces > Edit (for the adsl1/0 interface): Enter 1/32 in the
VPI/VCI field, click
Apply .
CLI
set interface adsl1/0 pvc 1 32
save
By default, the device uses 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:
WebUI
Network > Interfaces > Edit (for the adsl1/0 interface): Enter the following,
click
Apply :
VPI/VCI: 1 / 32
Multiplexing Method: LLC (selected)
CLI
set interface adsl1/0 pvc 1 32 mux llc
save
PPPoE or PPPoA
An SSG 20 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 device. To allow the device to connect to the service provider’s
network, you need to configure the username and password assigned by the service
provider. The configuration for PPPoA is similar to the configuration for PPPoE.
NOTE: The device supports only one PPPoE session on each virtual circuit.
