Description

Allows you to configure the traffic as per two rate three color policy specified in RFC 2698.

The no form of this command removes the metered traffic rate entries from the running configuration output.

Command context

config, config-class, and policy-qos.

Parameters

commit-rate: Configures the commit-rate as per RFC 2698.
commit-rate kbps<1-10000000>: Configures the commit-rate in Kb/s. Range: 1-10000000.
dscp-remark: Remarks the DSCP for traffic that exceeds the commit or peak-rate.
peak-rate: Configures the peak-rate as per RFC 2698.
peak-rate kbps<1-10000000>: Configures the peak-rate in Kb/s. Range: 1-10000000.
drop: Drops the traffic which exceeds the peak-rate.

Usage

If the traffic on the interface on which the policy is applied exceeds:

For the commit-rate, its DSCP is remarked to the configured value.
For the peak-rate, traffic is either dropped or DSCP remarked again.
