Hi all,
I am trying to limit the bandwidth to 10 mbps for one of my customer on 3550 switch.My configuration as follows but its not working.
mls qos
ip access-list extended upload
permit ip any any
class-map match-all INPUT
match access-group name upload
policy-map POLICY_INPUT
class INPUT
police 10240000 1920000 exceed-action drop
interface fastEthernet0/5
service-policy input POLICY_INPUT
1. Queueing strategy is still in fifo
2. HMG-2ndL3#sh mls qos interface fastEthernet 0/5
FastEthernet0/5
Attached policy-map for Ingress: POLICY_INPUT
trust state: not trusted
trust mode: not trusted
COS override: dis
default COS: 0
DSCP Mutation Map: Default DSCP Mutation Map
trust device: none
3. HMG-2ndL3#sh policy-map interface fa0/5 (packets are not hitting)
FastEthernet0/5
service-policy input: POLICY_INPUT
class-map: INPUT (match-all)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
match: access-group name DTDCqm_police_inform_feature: CLASS_SHOW
class-map: class-default (match-any)
0 packets, 0 bytes
30 second offered rate 0 bps, drop rate 0 bps
match: any
0 packets, 0 bytes
30 second rate 0 bps

Could you do a show class-map INPUT please?
Your sh policy-map interface fa0/5 shows the access-group as "DTDC", not "upload" as I would have expected.

Hi,
below is my orginal configuration in 3550. In my previous post i just manipulated the name of class-map and policiy map.
mls qos
ip access-list extended DTDC
permit ip any any
class-map match-all DTDC-INPUT
match access-group name DTDC
policy-map POLICY_DTDC
class DTDC-INPUT
police 10240000 1920000 exceed-action drop
interface fastEthernet0/5
service-policy input POLICY_DTDC
HMG-2ndL3#sh class-map DTDC-INPUT
Class Map match-all DTDC-INPUT (id 1)
Match access-group name DTDC

OK, that explains the discrepency.
So the next question must be .. (... and I'm sorry it looks like a dumb question ...) ... is Fa0/5 actually up, and is there any traffic actually passing through it?

can anyone help me to configure the bandwidth limt in 3550 switch in interface level , like how we will do it in cisco routers
by using rate-limit command.

On Cat switch for example on the Interface Configuration Mode on the switch port, you could apply the srr-queue bandwidth limit command. Here’s an example:
Switch(config)# interface FastEthernet 0/1 Switch(config-if)# srr-queue bandwidth limit 90
The 90 sets the outbound bandwidth limit on the port to 90 percent of the port speed. Since this is a 100-Mb port, this should limit the outbound traffic from the port to 10 Mb
Another example is on a Cisco router when in Interface Mode, you could limit outbound bandwidth to 1 Mb using the following command:
Router(config-if)# rate-limit output 10000000 2000 2000 conform-action continue exceed-action drop

Hi,
first thanks for your reply
rate-limit output is for the download traffic
rate-limit input is for upload traffic in serial interface
i am trying to do the bandwidth limit for my customer upload traffic.
cisco 3550 (input rate)<---------fiber link ---------->(output rate) customer device
also i check in my 3550 fastethernet interface there is no command like
srr-queue bandwidth
that might be due to my IOS
HMG-2ndL3(config-if)#srr-queue ?
% Unrecognized command
Is there any other alternative way to do this.

sorry the srr-queue is not avialable under cat 3550.
See this link how to setup policing for what you are trying to do

you need to apply a policy-map which polices the traffic to the rate that you want and then apply it via the service-policy command on an interface
