One-Rate Rate-Limit Profiles Overview

E Series routers implement a single-rate rate limiter, which you can configure to
provide more efficient service to TCP applications. With the single-rate rate limiter,
when the committed rate is exceeded, the rate limiter drops a single packet and then
resumes transmission up to a configurable burst window. The single, unacknowledged
packet causes TCP to cut its transmission rate in half rather than falling back to its
initial window size.
NOTE: Commands that you issue in Rate Limit Profile Configuration mode do not
take effect until you exit from that mode.
The one-rate rate-limit profile attributes are:

One-Rate Rate-Limit Profiles Overview
Create policy list P2.
host1(config)#ip policy-list P2
host1(config-policy)#classifier-group data2
host1(config-policy-classifier-group)#rate-limit-profile rlpData
host1(config-policy-classifier-group)#exit
host1(config-policy)#exit
Attach IP Policy P2 at interface atm5/0.2 with the merge keyword.
host1(config)#interface atm 5/0.2
host1(config-If)#ip policy-parameter reference-rate refRlpRate 100000
This increases from 0.
host1(config)#ip policy-parameter reference-rate refRlpRate increase 100000
This increases from the existing 100000.
host1(config)#ip policy input P2 merge
Verify the configuration.
host1#show policy-parameter
