Setting up permanent virtual circuits (PVC)
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.
Table 7. PVC Commands
| Command | Purpose |
|
|
|
Step 1 |
| Creates PVC 8/35 and enters configuration |
|
| mode for this PVC. The |
|
| PVC configuration. |
Step 2 | node(pvc)[8/35]# encapsulation {llcvc} | Sets the encapsulation to be used. Optionally |
|
| select either LLC encapsulation or VC multiplex- |
|
| ing for this PVC. |
|
| Default: llc |

Using PVC channels in bridged Ethernet mode
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.
Table 8. PVC channels in bridged Ethernet mode
| Command | Purpose |
|
|
|
Step 1 | node(pvc)[vpi/vci]# [no] bind interface | Associates an IP interface configuration with this |
| PVC. | |
|
|
|
Using PVC channels with PPPoE
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.
Table 9. PVC channels in PPPoE mode
| Command | Purpose |
|
|
|
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. |
| scriber |
|
Step 4 | node(session)[<name>]# no shutdown | Enables the PPPoE session |
|
|
|
Note 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.
