mscAtmIfMaxVpiBits 1.3.6.1.4.1.562.36.2.1.114.110.1.85

This attribute specifies the maximum number of VPI bits that may be active for this AtmIf. These bits start at the least significant bit position and are contiguous. In general, the maximum VPI which may be used on the interface is 2**maxVpiBits - 1. The value of the remaining (inactive) VPI bits is ignored on cells received from the link. If the AtmIf is linked to a LogicalProcessor of cardType 3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm, 3pDS3Atm, 3pE1Atm, 3pDS1Atm, or 2pJ6MAtm, the value of this attribute must be 8. The maximum VPI supported on these card types is 255. If the AtmIf is linked to a LogicalProcessor of any other cardType, the value of this attribute may be 8 or 12. The maximum VPI supported on these card types is 4095. An exception is that cardType 8pE1Atm and 8pDS1Atm do not support VPI 4095; the maximum VPI on these card types is 4094. If a Uni or an Iisp component is present directly under the AtmIf, the value of this attribute must be 8.
