This counter reports the average bit rate of rate-limited traffic received at this flow point during the current interval. It tells the admin whether the flow point's rate-limiting function is actively constraining inbound traffic, useful when diagnosing whether a subscriber's flow is being capped below their configured rate. For example, if a customer's upload speed test consistently caps at a certain value, the admin would check cmFlowPointStatsABRRLRx to confirm the flow point's rate limit is what's constraining it.
