The granted burst rate of the flow. The base unit of this
object is 1 kilo-bits. If the status of this row is not
active, the value of this object will be the same as
caqFlowPolicerBurstSizeRequest's value.
If the QoS function is enabled and the policy source is from
local configuration, this MIB object is from the runtime
hardware information. Due to hardware granularity, the
granted value may not be the same as the value specified
by caqFlowPolicerBurstSizeRequest object. It will be the
closest value to the requested one that the hardware can
support.
