ATM Configuration Commands 335
interface-num: Interface number, which can determine an ATM interface together
with interface-type.

specified, the information about all PVCs within the specified ATM interface will
be displayed by default.
vpi/vci: VPI/VCI pair, optional. For more details, please refer to “Parameter
Description” in the pvc command.
Description
Using the display atm pvc-info command, you can view the information about
PVC.
The interface-name parameter is actually composed of interface-type and
interface-num. The difference of using them only lies in the space. In the
command line, there are spaces in interface-type and interface-num, but there is
no space in interface-name.
For the related command, see pvc.
