POLICE TWIN RATE ACTION

police twin-rate action

Overview Configures a twin-rate policer for a class-map.
police twin-rate <cir> <pir> <cbs> <pbs> action
Syntax
{drop-red|remark-transmit}
Mode Policy Map Class Configuration
Usage A policer can be used to meter the traffic classified by the class-map and as a result
will be given one of three bandwidth classes. These are green (conforming), yellow
(partially- conforming), and red (non-conforming).
A twin-rate policer is based on four values. These are the minimum rate (CIR),
minimum burst size (CBS), maximum rate (PIR), and maximum burst size (PBS). The
following table shows how these values define the bandwidth classes.
Using an action of drop-red means that any packets classed as red will be
discarded.

Class Definition
green
The sum of the number of existing (buffered) bytes plus those arriving
at the port per unit time results in a value that is less than that set for
the CBS.
yellow
The sum of the number of existing (buffered) bytes plus those arriving
at the port per unit time results in a value that is between those set for
the CBS and the PBS.
red
The sum of the number of existing (buffered) bytes plus those arriving
at the port per unit time results in a value that exceeds that set for the
PBS.
