This read-create Unsigned32 holds the low-order 32 bits of the Policer's Committed Information Rate (CIR), paired with a Hi object to form the full 64-bit committed rate. An administrator sets this together with CIRHi to define the guaranteed rate below which traffic on this flow point is always marked as conforming (green). For example, configuring a policer to guarantee several hundred megabits per second requires setting this Lo value along with its Hi counterpart to represent the complete CIR.
