Configuring Terminating PVC Connections
This section describes configuring point-to-point and point-to-multipoint terminating permanent virtual
channel (PVC) connections. Terminating connections provide the connection to the ATM switch router’s
route processor for LAN emulation (LANE), IP over ATM, and control channels for Integrated Local
Management Interface (ILMI), signalling, and Private Network-Network Interface (PNNI) plus network
management.

Terminating PVC Types
Point-to-point and point-to-multipoint are two types of terminating connections. Both terminating
connections are configured using the same commands as transit connections (discussed in the previous
sections). However, all switch terminating connections use interface atm0 to connect to the route
processor.

Note
Since release 12.0(1a)W5(5b) of the system software, addressing the interface on the processor (CPU)
has changed. The ATM interface is now called atm0, and the Ethernet interface is now called ethernet0.
The old formats (atm 2/0/0 and ethernet 2/0/0) are still supported.
