Dear all
I have a cisco 837 router and i want to apply rate-limit command OR traffic limit or shapping command or QOS command or whatever

I want to restrict traffic on my LAN so that no one user uses too much bandwidth. I understand that the rate-limit command is a good way to do this but i dont know if its applicable to my router or not. Let's say that my users are assigned addresses in a 192.168.1.x network and I want to restrict all the IP's in that range so that each IP can get MAX 1024k bps bandwidth.

I want to verify that this will limit the rate for each specific IP (user) in the network and not limit the entire interface

Can someone provide an example of what the command for this would look like?

this is the version i have

ROM: System Bootstrap, Version 12.2(8r)YN, RELEASE SOFTWARE (fc1)
Cisco C837 (MPC857DSL) processor (revision 0x500) with 44237K/4915K bytes of mem
ory.

thanks in advance for ur help
 
Hello
The (CAR) rate-limit command is the old way of doing if your router don't fully support the new way,you will have to upgrade your IOS or use CAR with an access-list.Below is an example of using the Modular QoS CLI (MQC) which is more flexible.

access-list 101 permit ip 192.168.1.x 0.0.0.255 any

Class-map match-any SLOWDOWN
match access-group 101

Policy-map SLOWDOWN
class SLOWDOWN
police 1024000

interface atm0
service-policy input SLOWDOWN

If you want to do traffic shaping instead,you can use the "shape" command under the policy-map instead.


Regards

You fat fingered the entry...

class-map match-any SLOWDOWNM

Note the "M" at the end...:)

Hello
Burt has replied to your last post.I did revised the conf I sent you and have notice that you are doing "NAT" so you will have to put the policy-map on the outbound side of the ATM interface:

interface atm0
service-policy output SLOWDOWN

Good luck
