Description: An entry in the table, containing total

performance and error statistics for a single

group. 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.
