This read-only Counter64 reports the amount of out-of-profile traffic, meaning traffic exceeding the single policer's configured rate, for that policer. A rising out-of-profile counter tells an admin that a given policer is actively catching traffic exceeding the configured rate, which may indicate a client exceeding their contracted bandwidth. For example, an admin seeing a spike in this counter for a specific customer's policer would investigate whether that customer needs a higher committed rate or is misbehaving.
