This read-create Unsigned32 represents the higher 32 bits of the SOAM Excess Information Rate on an F3 network port's QoS shaper, used when that reserved excess allowance for OAM/CFM traffic exceeds a 32-bit value. Administrators set it in conjunction with the SOAM EIR low-order object on ports with very large SOAM excess allocations. For example, a high-capacity aggregation port with generous OAM burst tolerance would need this high-order field populated to fully express the SOAM EIR.
