This read-only integer reports the Received Average Information Rate in kilobits per second for the connection's ingress traffic. An administrator monitors this as a real-time bandwidth-usage gauge, comparing it against the connection's configured cir to see whether the channel is running near, at, or below its committed rate. For example, an rcvKbpsAIR value consistently well above the connection's configured cir would suggest the connection is regularly bursting into excess-rate territory on ingress.
