Setting up permanent virtual circuits (PVC) 39SmartNode 4950-NCE Getting Started Guide 5 • G.SHDSL Basic ConfigurationSetting up permanent virtual circuits (PVC)The modems currently available are using ATM to multiplex traffic over the DSL framing connection. ATMallows you to have separate logical connections running in parallel. Those connections are called permanentvirtual circuits (PVC). All permanent virtual circuits use AAL5 framing.Using PVC channels in bridged Ethernet modeThe 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 thePVC like it would be done to a normal Ethernet port.Using PVC channels with PPPoEThe RFC1483 bridged Ethernet connection can also be used for PPPoE. To do this, you enter PPPoE modewithin the PVC mode. All PPPoE commands apply as if the PVC was a regular Ethernet port.Note The bridged PVC connections are internally mapped to VLANs on a virtualEthernet port 0/2. You will therefore see references to this third Ethernetport when displaying PPPoE status information or debug logs.Table 8. PVC CommandsCommand PurposeStep 1 node(prt-dsl)[0/0]# [no] pvc vpi 8 vci 35 Creates PVC 8/35 and enters configurationmode for this PVC. The "no"-variant deletes thePVC configuration.Step 2 node(pvc)[8/35]# encapsulation {llc|vc} Sets the encapsulation to be used. Optionallyselect either LLC encapsulation or VC multiplex-ing for this PVC.Default: llcTable 9. PVC channels in bridged Ethernet modeCommand PurposeStep 1 node(pvc)[vpi/vci]# [no] bind interface

PVC channels in PPPoE modeCommand PurposeStep 1 node(pvc)[vpi/vci]# pppoe Enters PPPoE configuration mode for this PVC.Step 2 node(pppoe)# session Defines a PPPoE session.Step 3 node(session)[]# bind sub-scriber Links the session to a subscriber definition.Step 4 node(session)[]# no shutdown Enables the PPPoE session
