Answer: MIR provides a mechanism to limit the rate at which traffic can be received or sent to a station over its wireless interface. There is a default profile, but it is available to be modified. The minimum value is 100kbps, and the maximum value is 100Mbps in each direction. Operators may add up to 16 MIR profiles on the the ePMP AP, each with unique limits for uplink and downlink data rates.
Note : VoIP traffic is an exception, wherein even though you set a cap on VoIP traffic, it will exceed the cap if needed.
