Exactly as described, this sets the maximum bandwidth used to generate excess, or yellow, test traffic for this profile, and when testing for the red condition this same value is automatically multiplied by 1.25. This is what lets a single profile validate not just the committed rate but also how the circuit behaves when pushed beyond it, into the burst-tolerant yellow zone and then into the deliberately-oversubscribed red zone, without the operator needing three separate test profiles for the three traffic conditions. For example, an excess bandwidth of 200Mbps would automatically drive the red-condition test leg to 250Mbps, verifying the circuit correctly discards traffic beyond both the committed and excess allowances.
