Cisco 3550-EMI and QoS

[jonas21]

Hi,

i just got a 3550-EMI and want to QoS limit the bandwidth on some ports.
Heres my setup:

Port 1 Uplink
Port 2 to 48 Servers
All Ports are in Vlan1.
IP Routing is DISABLED.

(Background Info: The switch should limit the customer servers to given bandwidth limits that they purchased.)

I found some stuff about QoS on CCO but no example howto actually rate-limit the bandwidth (in and outgoing) on a interface. I played a bit and only got incoming rate-limit's to work. Could anyone paste his config if he/she got this to work?

Thanks,
Jonas

here is my config which works



The match access-group xxx refers to an access list which you need to configure to match both incoming and outgoing traffic, and then you need to apply the traffic-shape policy to the relevant interfaces.

Hi Hunter,

thanks alot!

Does this work for incoming and outgoing bandwidth?
I just see the service-policy input traffic-shape for input...but not output?

What are your dcsp paramenters or dont you use any at all?

Thanks,
Jonas
