You have the correct formula, the statement you need if you use policing should look something like this.
police 3000000 375000 conform-action transmit exceed-action drop You may want to consider shaping instead of policing as it will most likely give you better performance. With policing or shaping all traffic that exceeds the rate is dropped. The drops will cause the TCP windows to reset for each flow that the exceeding packets belong to and applications to slow. When using policing, as traffic burst it is more likely to reach the limit which can cause drops and spikes in the traffic pattern. With shaping the traffic is buffered in an attempt to spread the traffic out so that it doesn’t reaching the limit. Shaping tries to avoid drops and TCP window resets, which in turn can provide better utilisation of bandwidth. The config would look something like this. policy-map vpn-policy1 class good bandwidth 3000 shape average 3000000 3000000 0 regards, Mike Erek Riccobuano wrote: > > I want to police traffic on a 3550 so that one port is set to > 3Mbs another is 10Mbs and another is 1.5Mbs.
