This read-create Integer32 sets the Excess Burst Size (EBS) of the Policer, the token bucket depth governing how large a burst of excess (yellow) traffic can pass before being marked non-conforming. An administrator tunes this to allow short bursts above the EIR without immediately discarding traffic, while still bounding sustained overuse. For example, raising the EBS on a policer serving bursty backup traffic lets brief spikes pass as yellow rather than being dropped outright.
