This read-only object reports the decay factor, expressed as a power-of-two exponent up to 16, used when calculating the WRED queue's average depth. Per the desc, a smaller exponent value means the average decays, or reacts to changing queue depth, faster, while a larger value smooths out short-term spikes more. An admin reviewing WRED behavior would check cwredConfigGlobQueueWeight to understand how responsive the queue-average calculation is to sudden bursts of traffic versus sustained congestion.
