Hi Dave

Sup 1A and 2 can only do Ingress policing. Egress policing was new on
the 6500 Sup720.

hardware there to perform the action unless it's a 720.

We had a very similar situation last year.
You're correct... 3550 only polices. But at least it polices output,
which a Cat6K Sup1/Sup2 can't do.
At that time ... you were limited to (with cisco gear) the following
devices that could shape.
- An IOS Router
- Cat4K with Sup IV
- Cat6K with Sup720 (with the new line cards)
- Cat6K/7600with OSM line card (Big $$$$$)
- You can now look at the new 3750 Metro switch.. It's probably their
most affordable high speed shaper
For 4 Mbs you could use a regular router. A 2621XM might be big
enough ..
2951/2691/3700 would be better. We tested 7301s shaping up to 150Mbs
with out problems.

Hello group,
Suppose we have a cat 3550 configured as a L3 switch connected to an ISP.
The connection is at 100Mbps but the provider is rate limiting at 4 Mbps. I
suppose the ISP is dropping all the traffic bursting beyond 4 Mbps. Also I
suppose it is very easy to burst beyond 4 M if the link is configured at 100
M ?
What could you suggest as a solution. I would like Traffic Shaping but with
Cat3550 it's only possible to do Traffic Policing no ?
Thanks,
Richard Dumoulin
