Re: 3550 QoS - Police problem

Hi.

If I understand it right from DocCD, normal burst is what you have above 
the police rate. 256k-128k=128k => to bytes 16000/ If it should be 
considered together with police rate, then just 256k=>32000 bytes. In 
either case police rate should be 128000, not 256000 IMO.

I would go for
police 128000 16000 exceed action drop
