Jens,
This is from an earlier post.
***********************************
Let me try again but this time comparing police and bandwidth.
In an earlier post on this thread I asked you what happens during periods of
congestion and during periods of non-congestion with each command.
I believe the police sets a maximum which is always active but doesn't set a
minimum. Therefore, by using the police command alone, you can't guarantee
any amount of bandwidth during periods of congestion.
The bandwidth command does set a minimum so even during periods of
congestion, that class of traffic will get the specified amount of
bandwidth.
So, I see no problem with using both commands together.
The bandwidth command sets the minimum and the police command sets the
maximum and these settings will always be true and in effect regardless of
congestion or lack thereof.
HTH, Tim

Jens,
The bandwidth and police commands are NOT mutually exclusive.
It is OK to use both for the same class of traffic and it might make sense
to do so.
Please see my earlier post on this.

Hi,
I think the reason there is nobody telling you this is that this is not
something that makes sense to do. If you try understand what the two
different QoS technics are doing you will be able to see that for your
selfe. As several others also has said to this post earier is that this is
something that is not you would do. You know that you will learn a hell of a
llot more by finding out how technologis are working by your selfe rater
than somebody telling you this. Anyway, you have got so many hints from
bright people here on this forum regarding this, so you should be able to
figure this out.. This QoS technologies are not similar, and work in
different ways.
Happy studying..
Jens Petter Eikeland

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.
