This read-create Unsigned32 holds the upper 32 bits of the Service OAM Committed Information Rate (SOAM-CIR) on a Quality-of-Service Shaper, paired with cmQosShaperSoamCIRLo for rates exceeding 32 bits. Admins use this high-order field only when the reserved OAM bandwidth itself needs to be unusually large, which is uncommon since SOAM traffic is typically a small guaranteed trickle rather than a bulk rate. For example, on a shaper where SOAM-CIR is provisioned at just a few kbps, cmQosShaperSoamCIRHi would remain zero, with the entire value carried in the low-order SoamCIRLo object.
