This read-create Unsigned32 holds the high-order 32 bits of the Shaper's Excess Information Rate (EIR), paired with a Lo object to represent the full 64-bit excess rate value. An administrator configures this when the desired excess rate for a flow point is large enough to require both halves of the split value. For example, giving a high-bandwidth flow point a multi-gigabit excess allowance means this Hi object, together with EIRLo, must be set to reflect that full rate.
