How can I limit the bandwidth on a DS3? Are there several options to satisfy this goal? I am wanting to test some wan optimization solutions, but am curious if we can cut back the bandwidth and still see the same or better performance.
The example illustrated below limits the rate by application:
â¢All World Wide Web traffic is transmitted. However, the IP precedence for Web traffic that conforms to the first rate policy is set to 5. For nonconforming traffic, the IP precedence is set to 0 (best effort).
â¢FTP traffic is transmitted with an IP precedence of 5 if it conforms to the second rate policy. If the FTP traffic exceeds the rate policy, it is dropped.
â¢Any remaining traffic is limited to 8 Mbps, with a normal burst size of 16000 bytes and an excess burst size of 24000 bytes. Traffic that conforms is transmitted with an IP precedence of 5. Traffic that does not conform is dropped.
Notice that two access lists are created to classify the Web and FTP traffic so that they can be handled separately by the CAR feature.
Its bandwidth limitation, if you limit the bandwidth & utilizes it , then it will impact the performance of the Network unless you then implement Congestion Managment to priotrize specific Traffic Over another.
As for limiting your bandwidth, u could acheive that by implementing Policing:
class-map match-any limit
match access-group 100
access-list 100 permit ip any any
police (Your desired bandwidth) conform action transmit exceed action drop
