Description: An entry in the table, containing information, total performance and error statistics for a single group of ports. Regular retrieval of the information in this table provides a means of tracking the performance and health of the networked devices attached to this group's ports.

The counters in this table are redundant in the sense that they are the summations of information already available through other objects. However, these sums provide a considerable optimization of network management traffic over the otherwise necessary retrieval of the individual counters included in each sum.
