Rate limit a certain pvc on an ATM interface on DSLAM

Dear Sir
I want to rate limit a certain pvc on an ATM interface on DSLAM 6260, Taking into consideration that i have tried all the kind of configuration using the rx-cttr and tx-cttr but all was useless.
Could you please guide me how to do that, especially if i have a multiple pvcs on the same ATM interfaces and i need each not to raise above certain limit?
Thanks in advance

Dear Sir
First thank you for your reply and concern.
Here is the version 12.2(12)DA8 as i told you it is a Cisco DSLAM 6260 with NI-2, and as i got from the TAC that it is the latest (as far as i know).
Thanks a lot

How to rate-limit different IP's entering/leaving an Interface?

Hi There,
We are an ISP and have an interconnect with say Provider A. Customers of ours use Provider A for layer 2 and us for Layer 3 (IP/Internet).
Customer #1 to #100 --- (10Mb) --> Provider A ---> ISP ---> Internet
We'd like to rate limit some customers to 2mb/sec (in/out) on our end because at present they have a 10mb/sec connection coming from Provider A.
The config we use to peer with Provider A is this:
interface GigabitEthernet0/1.120
description Interconnect with Provider A
bandwidth 400000
encapsulation dot1Q 120
ip address A.B.C.1 255.255.255.252
Customers of ours are simply routed out through this interface like so:
Customer #1:
ip route W.X.Y.Z. 255.255.255.255 A.B.C.2
Customer #2:
ip route J.K.L.M 255.255.255.255 A.B.C.2
Is there a way to rate limit both these customers without needing to create a separate class map for each like so:
class-map match-all CUSTOMER-1-2MB
match access-group name ACL-CUSTOMER-1
class-map match-all CUSTOMER-2-2MB
match access-group name ACL-CUSTOMER-2
policy-map POLICY-RATE-LIMIT
class CUSTOMER-1-2MB
police 2000000 375000 750000
class CUSTOMER-2-2MB
police 2000000 375000 750000
interface GigabitEthernet0/1.120
service-policy input POLICY-RATE-LIMIT
service-policy output POLICY-RATE-LIMIT
I've done this in the lab and I know it works, so Customer #1 ends up with 2mb/sec and Customer #2 gets 2mb/sec too.
But in production, I'm talking about 100's of customers which we simply route out of this interface. I can't imagine having to configure 100's of class maps and policy maps for each customer to rate limit them to 2mb/sec like in the config above.
Is there a better way to do this on the router???
Thanks.
Andy

Hi All,
Doing what Laurent suggested works great. We are able to rate-limit the desired customers by having a separate class-map for each customer that needs to be rate limited under the single policy-map.
But now we're finding that the CPU utilization has increased by 20% because of this.
We're pushing about 400M through this interface and rate limiting 7 customers on it.
Given the large traffic flow through this interface (400M), is it common to see an increase in CPU utilisation by 20%???
When we take the service-policy off the interface, sure enough the CPU drops by 20%.
Here's the MQC applied:
interface GigabitEthernet0/1.120
bandwidth 400000
encapsulation dot1Q 120
ip address 203.17.x.x 255.255.255.252
ip flow ingress
service-policy input RATE-LIMIT
service-policy output RATE-LIMIT

class-map match-all CLASS-TCS-205560
description Customer #7 rate limited to 4mb/sec
match access-group name ACL-TCS-205560
policy-map RATE-LIMIT
class CLASS-TCS-200005
police 2000000 375000 750000 conform-action transmit exceed-action transmit violate-action drop
class CLASS-TCS-200208
police 2000000 375000 750000 conform-action transmit exceed-action transmit violate-action drop
class CLASS-TCS-200441
police 4000000 750000 1500000 conform-action transmit exceed-action transmit violate-action drop
class CLASS-TCS-200338
police 4000000 750000 1500000 conform-action transmit exceed-action transmit violate-action drop
class CLASS-TCS-205679
police 4000000 750000 1500000 conform-action transmit exceed-action transmit violate-action drop
class CLASS-TCS-205560
police 4000000 750000 1500000 conform-action transmit exceed-action transmit violate-action drop
class CLASS-TCS-205593
police 3000000 562500 1125000 conform-action transmit exceed-action transmit violate-action drop
Is this the correct behaviour of applying the service-policy to the interface whereby the CPU increases by 20% or can the MQC be fine tuned to have less of an impact on the CPU?
Is the router just overloaded, taking into account it's only pushing about 400M? Should it be able to do more than this??
Thanks.

ASA rate limit certain websites

Hello,
Is there a way with the ASA to rate limit certain websites? Match using regex but rate limit only those matches?
For example if I wanted to rate limit youtube, could I match youtube in a regex statement and then inspect http and only rate limit youtube and not the rest of the http traffic?
When I set the rate limit it allways seems to rate-limit whatever I am inspecting, eg http in general.
Or should I look at doing this on my router instead?
Thanks,
Dan.

Dan,
OK - I forwarded that particular example as the way I look at it, it tells me:-
1) How to configrure RegEx
2) How to configure a specific URL to perform an action (it just happens in this example it's a block action)
3) Assign it to a class map
Once you have it in a class map, you are almost there - in theory (I have not tried this) but since you will have a class map, you should be able to assign it to a QoS policy map, rate limiting the amount of traffic?
See the below example of a QoS Rate Limit

Rate-Limit BRI

I was working with a co-worker who was seeing FTP choke the B channel when a remote router was on ISDN. Normally we use rate-limit on the frame-relay PVC's, which works great, but when I configured it on the BRI0/0/0 interface, I was not seeing hits on the ACL. Is rate-limit supported on BRI interfaces?

At this point we are back on the frame-relay connection, so show output wouldn't be helpful. Here's the interface config.
interface BRI0/0/0

ICMP unreachable, rate-limit command

Hi !
I'm currently working on projet of network hardening.
Based on Cisco security best pratice, I see it's recommand to rate limit genaration of ICMP unreachable message to prevent DoS attack. (according to document : http://www.cisco.com/application/pdf/en/us/guest/netsol/ns171/c649/ccmigration_09186a0080825564.pdf page 74)
On Catalyst 6509 run IOS 12.2(17r)SX5 I see to possible way to rate-limit ICMP messages if mls QoS is running.
1- mls rate-limit unicast ip ICMP unreachable acl-drop 100 10 (enable by default, according to document : http://www.cisco.com/application/pdf/en/us/guest/netsol/ns171/c649/ccmigration_09186a0080825564.pdf page 74)
mls rate-limit unicast ip ICMP unreachable no-route 100 10
2- ip ICMP rate-limit unreachable <millisecond> (500 ms is default parameters, which permit 2 paquets per seconds, also enable by default if I'm base on : http://www.cisco.com/warp/public/707/cisco-sn-20030125-worm.shtml, ACL for IOS section)
Which one of those command have precedence over the other one ?
Which one is better over the other one ?
With the mls rate-limit option, we have the possibility to check default parameter with : "show mls rate-limit" command is exist equivalent for : "ip ICMP rate-limit unreachable"
We have also Catalyst 3550 switches, on which we have to rate-limit genaration of ICMP unreachable message for same reason as 6509. I understand the :"ip ICMP rate-limit unreachable" command is my only option "under "mls " the only option I have is QoS or aclmerge. Under thoses parameter I have no way to rate-limit ICMP message generation....
I have check in running-configuration I did not find any reference to ICMP rate-limit command, I hope this is active like explain in document http://www.cisco.com/warp/public/707/cisco-sn-20030125-worm.shtml, ACL for IOS section, (Version 12.2(44)SE3) but I would like to be able to confirm if any show command exist to confirm this.
thanks a lot !

Possible to rate limit console input?

I built a tool that allows us to input device information such as IP, VLAN, etc, etc and this tool builds the entire config file that can be pasted into a switch/router. The problem is that when I start getting down near the banner and motd sections, the console cannot keep up with the input and it drops lines of input.
Is there a way to rate limit the input when large configs are pasted into con 0?

Bandwidth Rate-Limit -w- WWR-Queue

How would one convert a layer-2 port's "switchport rate-limit" bandwidth statement, on a 6509 -w- WS-X6748-SFP ports, to a routed/layer-3 "wrr-queue" bandwidth statement policy? Basically trying to hard-core the port's speed to 20MB. Current/tested layer-2 port bandwidth setting:
rate-limit input 20000000 5000 5000 conform-action transmit exceed-action drop
rate-limit output 20000000 5000 5000 conform-action transmit exceed-action drop
Got lost in how to use/configure all WRR's four queues... just need to limit the port's bandwidth to 20MB. Any suggestions would be appreciated.
Thanks, Kevin

1) Enabled QoS globally...
2960(config)#mls qos
2) Configure an ACL to define the matched traffic...
2960(config)#access-list 111 permit ip any any
3) Configure a class map for the matched traffic...
2960(config)#class-map traffic
2960(config-cmap)#match access 111
4) Configure a policy-map to define action...
2960(config)#policy-map Control
2960(config-pmap)#class traffic
2960(config-pmap-c)#police 10000000 8000 exceed-action drop
5) Attached the policy-map to the interface.
a) Example
-In this case, I'll attach the policy map to port_1....

Per user bandwidth rate limit.

How to configure per user bandwidth rate limit for wireless guest client, authentication server is ISE 1.2 & wireless controller is 5760.

The Cisco 5760 WLC supports better QoS than other c
ontrollers, allowing prioritization of mission-crit
ical
applications:
●
The Cisco 5760 WLC supports four wireless hardware
queues and priority-based queuing compared to
software-based queuing in existing controllers.
●
The Cisco 5760 WLC follows MQC based commands, allo
wing usage of exact commands for configuring
QoS on different types of network devices.
●
The Cisco 5760 WLC supports QoS policies to be appl
ied in a hierarchical fashion with more granularity
per SSID per radio, while on the current controller
s granularity is per WLAN.
●
The Cisco 5760 WLC supports approximate fair bandwi
dth to make sure of fairness at client, SSID, and
radio levels for Non-Real Time (NRT) traffic. There
fore, if one user consumes excessive bandwidth, we
can
limit the amount of bandwidth that user receives an
d thereby not deprive other users.

WLC 5508 and Anchor/GuestNet rate limit traffic?

Running WLCs 5508s 7.0.116.0 with GuestNet and Anchor setup, how can I limit the bandwidth on the GuestNet SSDI to 2 Mbps, etc?
The DMZ WLC (Anchor) runs thru a ASA 5508 7x, can I rate limit traffic via ASA?

That's really a matter of preference. This document describes things to keep in mind when altering these QoS profile configurations, FYI.
http://www.cisco.com/en/US/partner/docs/wireless/controller/7.0MR1/configuration/guide/cg_controller_setting.html#wp1254532
It really depends on how many guests, what type of traffic, etc, to make a judgement call as to where you should set these. I'm sorry but I don't have any examples from existing configurations, but hopefully the document explains how to best alter these settings.

WLC user rate limit on guest ssid anchor controller

Hi,
I have been looking through the forums & some cisco documents but not found a good example similar to what I am seeking to do so now I am turning to the expertise of my peers.
We have been deploying 3502 APs remotely to locations with full T1s that backhaul to where I sit at HQ.
Both the foreign and anchor controller are here at my location.
I am seeking to rate limit per user the bandwidth each client will get on the guest internet ssid.
As you know this traffic is encapsulated in capwap between the AP and the controller so I cant use a standard ACL on the switch or router.
We are trying to keep the guest internet access usage in check on the T1 at any given site so the other ssid's & local lan traffic is not overly competing for the bandwidth.
I found the place to edit the default profiles in the controller but the documentation really isnt clear on best practices.
So I put it to you my fellow wireless engineers to suggest how you are implementing bandwidth management on your wireless guest internet.
Thanks guys!
Oh and here is my hardware & software levels.

Amjad,
Thank you for taking the time to respond as well as the document link.
It was pretty clear on the steps and what it would impact.
Two things that push me for a different solution (assuming their is one).
Note The values that you configure for the per-user bandwidth contracts affect only the amount of bandwidth going downstream (from the access point to the wireless client). They do not affect the bandwidth for upstream traffic (from the client to the access point).
As you can see from the above note taken out of the linked document the roll based rate limit doesnt really rate limit the T1 traffic any guest user consumes it only limits usage from the AP down to the client.
#1 I am looking for a solution that limits the users up & down streams (if possible) & also before it leaves the AP for the T1.
The idea is to limit WAN utilization.
#2 I read in the forums here others asking about the "user role" and saw some comments saying it is not considered "best practice" to use user roles.
Let me clarify that our guest ssid's are using the http webpage pass through for authentication and it is really only the tic mark to indicate they understand the terms and conditions of using our internet as a guest service. No actual user accounts are used on the guest ssid's.
***One last question about this and any other changes***
Will any change I make be on the "Foreign, Anchor" or both Controllers?

Rate-limit command 3560 does it exist?

I have just come across a command in my router IOS which might be useful too me. I was wondering if the following command is available on a 3560 Switch. I don't see it on my 3550 but the IOS is quite old. I don't have a 3560 avaiable currently to check.
Config t > int vlan x > rate-limit input/output
does this exist on the 3560? I am also interest if it does in the Bits per second range and if available input/output.
Thanks for any help

Bandwidth Management(Rate Limit) Using QoS Policies

Hello,
I need some advice. We have an ASA 5525 running version 8.6(1)2 and a 10 MG pipe. I have execs that want to limit bandwidth on users for stuff like youtube, stream media, and downloads. I found the article on ‘Bandwidth Management(Rate Limit) Using QoS Policies’ so it appears our firewall can do what we want. I’m not a cisco person. My knowledge is limited when it comes to configuration – that’s why we have SmartNet :). The advice I need is what to ask for, so to speak, when I put a case in. Can bandwidth be limited on end users and/or can they limit the ‘bandwidth rate limit’ to just youtube, steaming media, and downloads? If so, what should the limit be? and I’m assume this would be for ‘incoming’ traffic only? we’re running into some bandwidth hogs – usually youtube and/or streaming media. We have a Barracuda web filter which we’ve used to block and monitor activity but I simply do not have time to babysit this all day. I should also mention we do have critical data running up and down the pipe; such as credit card processing, DB replication between in house DB and hosted website, TPCx and EDI, FTP, and such that we don’t want restricted.
Need input please,
Thanks,
D

Hello,
That's a question that you as the network admin of that organization could answer.

Prime Infrastructure 2 - API rate limit change?

Good day -
The Prime API is pretty sweet, and can give you JSON data back easily with a call like this:
https://prime/webacs/api/v1/data/Clients.json?.full=true
It is, however, limited to 100 results. We'd like to see more than that.
How do I change this rate limit for the API?

I have found that this command does work, but still limits to 1000.
https://prime/webacs/api/v1/data/Clients.json?.maxResults=9999&.full=true
Now I get Tomcat a HTTP Status 503 error. There's another setting I've not found yet.
My json results say "@count":"6980", suggesting I have that many clients in the database.
