Jens,
Your description of the bandwidth command is correct if there is
congestion on the link. If there is no congestion, the bandwdith command
does not stop the traffic from exceeding the configured amount.

Just wanted to give you a hint to... the bandwith command will not allow
you exed the configured bandwith while with policing you will be able to
burst the traffic up to a configured limit. But I cant see any reason to
use them together.. so you see this are commands that works in different
fashion.

Emne: RE: SV: Qos question (bandwidth,police).
Hi,
Thank you very much for your reply and for the link. But there is
explained just how the police and bandwidth commands are used separetely
but not together. I just need to find the difference between:
1.
policy-map LIMIT
class web
police 100000 conform-action transmit exceed action drop.
and
2.
policy-map LIMIT
class web
bandwidth 100
police 100000 conform-action transmit exceed action drop.
Could anybody tell something?? Because I don't see any. As I think
during the congestions both configs don't let traffic to be more than
100 M and when there is no congestion there are no limiting in both
case. Thanks.
