is a percentage of bandwidth that will be dedicated to traffic in a group if necessary.
If the traffic does not require the full allocation, unused bandwidth will be available to
other groups.
The total percentage assigned to all sixteen groups can be greater than 100%. This
allows allocating 100% to, for example, four or five groups that will be used for a par-
ticular type of traffic, and 100% to another few groups, and so on. Since usage obvi-
ously cannot exceed 100%, any allocation of greater than 100% will be treated as
100%, with the percentages assigned to the affected groups treated as relative per-
centages. For example, assume that Group 1 is assigned 60% and Group 2 70%, and
both groups are assigned to IP interfaces. Under a full traffic load, Group 1 will be
allocated 60/130 (46%) of the available bandwidth, and Group 2 will be allocated 70/
130 (54%).
prioritizes traffic within each group; the higher the number, the higher the priority.
The priority is generally applied to traffic that exceeds the specified percent of band-
width.
