rpMauGroupIndex 1.3.6.1.2.1.26.1.1.1.1

This variable uniquely identifies the group containing the port to which the MAU described by this entry is connected. Note: In practice, a group will generally be a field-replaceable unit (i.e., module, card, or board) that can fit in the physical system enclosure, and the group number will correspond to a number marked on the physical enclosure. The group denoted by a particular value of this object is the same as the group denoted by the same value of rptrGroupIndex.
