if Chassis Logical Unit
The logical unit number of the specified interface. It is the logical part of the interface that is configured on the physical or channel part if any. Although the logical unit number is numbered from 0 and up in the interface naming, the return value for this object always starts from 1 according to Network Management convention. For the interface which is really a physical device, this value returns zero.
