This read-create Unsigned32 specifies the higher 32 bits of the Excess Information Rate for a port-level QoS shaper. Administrators populate it when the configured excess-rate allowance on the port is large enough to require more than 32 bits to represent. For example, a port with a multi-gigabit EIR allowance for a bursty backup traffic class needs this field set together with the low-order EIR bits.
