limiting bandwidth

[miss155159]

hello,

I want to limit the bandwidth of my Catalyst 3750 series switch, I read the cisco documentation and I applied the commands but I didn't get the wanted results.

for the outbount trafic it's ok, but for the inbound traffic I used policing but I get an unstable traffic.

I used, an access list and a class-map to classify the traffic and then a policy-map.(I followed the steps mentioned in this site: http://www.cisco.com/en/US/products/hw/switches/ps5023/products_tech_note09186a0080883f9e.shtml#concept11 )

someone has a solution?

sorry for my bad english and thanks for help.

you need to configure an aggregate-policer

according to the site you gave me, the agregate policer is used when we have more than one class, in my case I have only one class-map.

I  want to know if there is someone who configured a 3750 cisco switch and to reduce the bandwidth, it seems that it's impossible to have a stable traffic.

thanks.

Please clarify "stable" vs. "unstable" traffic.  Or, what's the issue you believe the policer is creating?

I have this configured on a 3750 to limit traffic to a particular server

class-map match-all SEP

match access-group name SEP

!

!

policy-map Police

class SEP

  police aggregate SEP

!

mls qos aggregate-policer SEP 1024000 192000 exceed-action drop

mls qos

!

ip access-list extended SEP

permit ip host 10.2.1.201 any

permit ip any host 10.2.1.201

permit ip host 10.2.1.48 any

permit ip any host 10.2.1.48

!

Int range fa1/0/1  - 48

service-policy input Police

int range giga 1/0/1 - 4

service-policy input Police

!

This works perfect to limit traffic to and from the 2 servers (10.2.1.201 and 10.2.1.48)

hello,

thanks for your answers, still now I don't have perfect results, what I mean by stability is that when I apply a policy and every time I do a test Imust have the same result ie the same rate, expect  this is not the case(when I tested the rate I didn't have the same results).

thank you any way.
