This read-create Unsigned32 holds the lower 32 bits of the Committed Information Rate (CIR) configured on a Quality-of-Service Shaper, the guaranteed throughput the shaper will always pass. Admins set this to enforce SLA-committed bandwidth, since traffic up to the CIR is shaped to pass reliably while anything above it competes for the shaper's excess allowance. For example, to guarantee a customer flow 50 Mbps of committed throughput, an admin sets cmQosShaperCIR to the value representing 50,000,000 bits per second (using cmQosShaperCIRHi only if the rate exceeds the 32-bit range).
