Early LLQ implementations actually enforced the implicit policer at all times, even with no congestion. Later they switched it to police only during congestion, so you need to use an explicit policer if you wanted to restore that behavior.
The RFC for EF (RFC2598) doesn't specify whether the rate limiter should apply only during congestion or at all times, as far as I can see. I have, at previous jobs, had an SP do the strict policing of EF traffic on ingress to the purchased rate. In those cases, we used an explicit policer to mark down overage rather than simply let the SP drop it. Bob -- Sent from my iPhone, please excuse any typos.
