This read-create Unsigned32 represents, per its description, the higher 32 bits of the SOAM Excess Information Rate on an F3 network port's QoS shaper, again labeled 'Higher' in the description despite the Lo suffix, echoing the same naming inconsistency seen on the regular EIR fields in this MIB. An administrator configures it to define how much OAM/CFM traffic above the reserved SOAM committed rate is still tolerated. For example, during a burst of diagnostic loopback traffic, this SOAM EIR setting determines whether those extra maintenance frames are shaped or passed through.
