This read-create Unsigned32 holds the higher-order bits of the Service OAM Excess Information Rate (SOAM-EIR) on a per-COS access-port QoS Shaper, paired with the lower-order SOAM-EIR object for larger values. It's relevant only when the OAM burst allowance itself needs to be unusually large on that access port's shaper, uncommon for typical CFM traffic volumes. For example, on a standard access port where SOAM-EIR is only a few kbps of burst allowance, cmAccPortQosShaperSoamEIRHi stays at zero while the value lives entirely in the paired low-order object.
