POLICE SINGLE

RATE ACTION
police single-rate action
Overview Configures a single-rate policer for a class-map.
Syntax
police single-rate < cir > < cbs > < ebs > action
{drop-red|remark-transmit}
Mode Policy Map Class Configuration
Usage You can use a policer to meter the traffic classified by the class-map and assign it
to one of three bandwidth classes.
The bandwidth classes are green (conforming), yellow (partially-conforming), and
red (non-conforming). A single-rate policer is based on three values. These are the
average rate, minimum burst and maximum burst.
Using an action of drop-red means that any packets classed as red are discarded.
NOTE
: This command will not take effect when applied to a class-map that attaches to
a channel group whose ports span processor instances.
Note that the remark-map does not only apply to red traffic. If a remark-map is
configured on the same class-map as the policer, then the remark-map will apply
to green- colored and yellow-colored traffic irrespective of the value configured on
the
action parameter of the policer. So, even if action is configured to drop-red,
the remark-map will be applied to green and yellow traffic. So, the action
parameter only applies to red- colored traffic. If action is set to drop-red , then red
Parameter Description
