This is the highest value recorded during the current performance-monitoring interval of the percentage of egress capacity being used on this interface during the current performance-monitoring interval. The highest egress utilization in the interval flags the busiest outbound moment, the figure an admin checks when a downstream site reports it isn't receiving data fast enough. For example, if a remote office reports slow file downloads specifically in the evening, an admin would check whether outUtilizationMax for that time window is near 100 percent, pointing to egress congestion rather than a problem at the remote end.
