vpi/vci
: Specifies a PVC by its VPI and VCI values. The value range for the
vpi
argument is 0 to 255.
The value range for the
vci
argument varies by interface type. For more information, see
The values of the
vpi
and
vci
arguments cannot be 0 at the same time. As a best practice, do not use
VCI values 0 through 31 because they are reserved for special purposes.
Usage guidelines
If you do not specify an ATM interface, this command displays brief information about all PVCs on all
ATM interfaces.
If you specify an ATM interface but do not specify a PVC, this command displays brief information
about all PVCs on the specified ATM interface.
If you specify an ATM interface and a PVC, this command displays detailed information about the
specified PVC.
