To configure tokenmt as a single-rate meter, do not specify a peak_rate parameter for tokenmt in the IPQoS configuration file. To configure a single-rate tokenmt instance to have a red, green, or a yellow outcome, you must specify the peak_burst parameter. If you do not use the peak_burst parameter, you can configure tokenmt to have only a red outcome or green outcome. For an example of a single-rate tokenmt with two outcomes, see Example 34–3.
When tokenmt operates as a single-rate meter, the peak_burst parameter is actually the excess burst size. committed_rate, and either committed_burst or peak_burst, must be nonzero positive integers.
