Hey Stefan,

Your question is a good one. I suspect many people might have the same
question - I know I did not that long ago.

Here's how I think about this:

When used in MQC, what exactly does the bandwidth command do?

What effect does the bandwidth command when the interface is and isn't
congested?

Suppose the interface isn't congested and the specified traffic exceeds the
amount specified with the bandwidth command, what happens?

Suppose the interface isn't congested and the specified traffic exceeds the
amount specified with the police command, what happens?

There's an excellent document on the cisco site that addresses these
questions but off-hand, I don't know the link. If you can't answer these
questions, find this doc and your answer will be there.

HTH, Tim

Subject: Qos question (bandwidth,police).

It is needed to limit the input of some WEB traffic to 100 Megabyte.

I saw such config in the book:
policy-map LIMIT
class web
bandwidth 100
police 100000 conform-action transmit exceed action drop.

Whe could the bandwidth here be used. Whey to command are used together
here.

As I know police is really limiting traffic to 100 Mb. But bandwidth is for
custom queuing.
Could anybody comment this configuration???? What would be the difference
between this config with or without bandwidth command.

Thanks.
