I need to limit the bandwith of a customer that mainly sends voice and video traffic. If I do this with policy maps will the outcome be something terrible, because voice and video is mainly udp traffic, and policing drops excessive traffic?
Any experiences from this? I need to do the limiting with 3560 switch so there isn't much options...

What do you mean by there isnt much options.
I think you can do what you need with the features available on the 3560.

Hi there,
Rather than policing, have a look at shaping.
As for drops, if your customer is using more bandwidth than they're allowed, then they should expect drops!!
Hope that helps,

How can I force a client on a specific port on my 3560 to have 30mb of bandwidth with shaping? All traffic from that port should share that 30mb.

The ingress bandwidth of the port need to be rate limited also. The egress bandwidth I do with srr-queue bandwidth limit weight1 command. The ingress I do with policy maps like this:
policy-map 4mb
class rate-limit
police 4096000 1000000 exceed-action drop
Class map is linked to acccess-list that matches any.
How this can be done with shaping? And yes I know where the configuration guide is...

Hello,
the Cisco 3560 switches do not support service policies assigned on the egress of an interface due to an ASIC limitation.
If you want to limit the egress to 30MB, you can do that with the 'srr-queue' command. To limit ingress traffic by policing the default class. The config would look like this:
mls qos
policy-map police_30M
class class-default
police 30000000 5120000 exceed-action drop
!
interface FastEthernet1/0/2
description oolice to 30 Mbps
speed 100
service-policy input police_30M
srr-queue bandwidth limit 30
Does that make sense ?
