This object reflects the type of ATM virtual interface that can be
configured within a physical interface. The supported types of virtual
interfaces and their description is shown below:
uni : Only one virtual interface of uni type can be configured within
a physical interface. The ATM cells used in this interface would
use a 8 bit VPI and a 4 bit GFC.
nni : Only one virtual interface of nni type can be configured within
a physical interface.The ATM cells used in this interface would
use a 12 bit VPI.
vnni: Multiple virtual interfaces of vnni type can be configured
within a physical interface. However, all cells sent on this
interface belong to a single VPI (defined by caviVpiNum) and
the cells use a 12 bit VPI.
vuni: Multiple virtual interfaces of vuni type can be configured
within a physical interface. However, all cells sent on this
interface belong to a single VPI (defined by caviVpiNum) and
the cells use a 8 bit VPI and a 4 bit GFC.
evuni: Multiple virtual interfaces of evuni type can be configured
within a physical interface. However, all cells sent on this
interface belong to a range of VPI (defined by caviMinVpiNum
& caviMaxVpiNum) and the cells use a 8 bit VPI and a 4 bit GFC.
evnni: Multiple virtual interfaces of evuni type can be configured
within a physical interface. However, all cells sent on this
interface belong to a range of VPI (defined by caviMinVpiNum
& caviMaxVpiNum) and the cells use a 12 bit VPI.
