Setting up permanent virtual circuits (PVC)

SmartWare Software Configuration Guide 

The modems currently available are using ATM to multiplex traffic over the DSL framing connection. ATM 
allows you to have separate logical connections running in parallel. Those connections are called permanent 
virtual circuits (PVC). All permanent virtual circuits use AAL5 framing.

The PVC offers a bridged Ethernet connection as specified in RFC1483, which can be used as an IP link e.g. 
with DHCP to assign the address, DNS server, and default gateway. To do this, you bind an IP interface to the 
PVC like it would be done to a normal Ethernet port. 

The RFC1483 bridged Ethernet connection can also be used for PPPoE. To do this, you enter PPPoE mode 
within the PVC mode. All PPPoE commands apply as if the PVC was a regular Ethernet port. 

The bridged PVC connections are internally mapped to VLANs on a virtual 
Ethernet port 0/2. You will therefore see references to this third Ethernet 
port when displaying PPPoE status information or debug logs.

Table 8. PVC Commands

Step 1 node(prt-dsl)[0/0]# [no] pvc vpi 8 vci 35 Creates PVC 8/35 and enters configuration 

mode for this PVC. The "no"-variant deletes the 
PVC configuration.

Step 2 node(pvc)[8/35]# encapsulation {llc|vc} Sets the encapsulation to be used. Optionally 

select either LLC encapsulation or VC multiplex-
ing for this PVC.
Default: llc

Table 9. PVC channels in bridged Ethernet mode

Step 1 node(pvc)[vpi/vci]# [no] bind interface 

Associates an IP interface configuration with this 
PVC.

Table 10. PVC channels in PPPoE mode

Step 1 node(pvc)[vpi/vci]# pppoe

Enters PPPoE configuration mode for this PVC. 

Step 2 node(pppoe)# session <name>

Defines a PPPoE session.

Step 3 node(session)[<name>]# bind sub-

Links the session to a subscriber definition. 

Step 4 node(session)[<name>]# no shutdown

Enables the PPPoE session
