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....
2960(config)#int fa0/1
2960(config-if)#service-policy input Control
>>>>>> This will rate-limit traffic coming from the PC

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.

Service-Policy Or Bandwidth Rate Limit for IP

Hii Netpros,
Is this possible to configure the Service Policy(for Bandwidth) or Bandwidth Rate Limit for Single IP. For eg: If we want to configure the Service Policy(for Bandwidth) or Bandwidth Rate Limit of 2Mb for only IP " 10.10.10.3" on network i.e the Host or device which is configured with this IP can access upto 2Mb only.
Actual Network :-   We need this to configure this for wireless customers, Actually we have created one Vlan 2 (IP:- 10.10.10.1/29 @ our end router) , 10.10.10.2 on Basestation wiresss device (Vlan 2 allowed on this wireless device) and this wireless device is working as point to multipoint wireless. i.e 2 or more then 2 wireless customers or last mile will connect to this basestation wireless. Wireless customer-1 is 10.10.10.3 (2Mb bandwidth) and Wireless Customer-2 10.10.10.4 (512Kb).
Hence we require to limit the bandwidth for this 2 wireless customers having different bandwidth. how to acheive & control bandwidth @ our end router for them. please suggest.
Thanks

This topic is probably better suited in another Infrastructure forum, but I suppose it depends on which features are supported by your Cisco hardware and software. This doc discusses a variety of options:
http://www.cisco.com/en/US/docs/ios/12_2/qos/configuration/guide/qcfpolsh.html
For example, with the older CAR (committed access rate) approach:
interface FastEthernet5/0
     rate-limit input access-group 101 20000000 [normal burst size] [excess burst size] conform-action transmit exceed-action drop
     rate-limit input access-group 102 5120000 [normal burst size] [excess burst size] conform-action transmit exceed-action drop
access-list 101 permit ip 10.10.10.3 0.0.0.0
access-list 102 permit ip 10.10.10.4 0.0.0.0
You can observe CAR in action with "show interfaces fa5/0 rate-limit" for example.

QoS bandwidth rate limit don't work

Hello
Buy a router RV120W, and one of the reasons is limit of bandwidth (QoS). I set up a profile of 1-256 kbps limit, and apply it to the only VLAN that is configured, but does not work and can navigate using the full bandwidth of the internet connection. My firmware version is 1.0.2.6
Screenshots attached
thanks
screenshots attached

Struggling with a similar issue:
the setup: internet adsl <--1mbs--> combined router/modem <--100mbs--> RV 120W
Internet speed is 1mbs. I want to priotize voip calls (via port) and deprioritize one machine (doing downloads). rest of the network should have something in between.
Firmware upgraded to 1.0.3.10
I created the profiles bindings, then in QoS settings, selected Priority, Wan total bandwidth 1mbs, and distributed my profiles onto low/med/high (10/31/61).
When what should be low is downloading, it gets the whole 1mbs and the other are dead slow.
Changed to rate limit, changed the parameters, etc... no more luck.
Can you please shed some light as how to configure this - in my case, the whole bw of wan is being used, and prioriization is not happening,

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.
How much traffic for business purposes must travel via HTTP/HTTPS?
How much bandwith are you willing to provide to this 2 protocols?
Those are the kind of answers you need to answer before setting the number

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

police 2000000 375000 750000 conform-action transmit exceed-action transmit violate-action drop

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.
Andy

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.
5508wlc - forgeign
4402wlc - anchor
Software Version
7.0.230.0

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 guest ssid 5500 foreign to 2504 anchor

Hi
We have a need to limit bandwidth on guest ssid that is tunnelled to anchor controller. The 2504 doesn't have rate limiting options but the 5500 does. If we enabled the rate limit on the SSID details on the foreign would it work (seeing as though the anchor can't have same settings). I would have thought that the access points terminate on the foreign therefore the rate limit would apply there.
Would this work or do I need another 5500 as the anchor so that rate limits can match on the SSID?

Thanks. It would be nice if Cisco documentation actually clarified this as all guest anchor docs seem not to mention having to have both controllers supporting QoS profiles.

Cisco SG300 VLAN rate-limit

I have a Cisco SG300 small business switch and 541 APs. There are 2 VLANs in our network. One must be limited by bandwidth. Does anyone have an idea for configure vlan rate-limiting on SG300? And please describe CIR & CBS for me. Thanks.

http://www.cisco.com/en/US/partner/products/ps10898/prod_command_reference_list.html
Cisco Small Business 300 Series Managed Switches Command Line Interface Guide Release 1.3
Select CIR and CBS according to your design. You can use a larger CBS when performance is not ideal.
49.23 rate-limit (VLAN)
Use the Layer 2 rate-limit (VLAN) Global Configuration mode command to limit the
incoming traffic rate for a VLAN. Use the no form of this command to disable the
rate limit.
Syntax
rate-limit vlan-id committed-rate committed-burst
no rate-limit vlan
Parameters
• vlan-id—Specifies the VLAN ID.
• committed-rate—Specifies the average traffic rate (CIR) in kbits per second
(kbps). (Range: 3-57982058)
• committed-burst—Specifies the maximum burst size (CBS) in bytes.
(Range: 3000-19173960)
Default Configuration
Rate limiting is disabled.
Committed-burst-bytes is 128K.
Command Mode
Global Configuration mode
User Guidelines
Traffic policing in a policy map takes precedence over VLAN rate limiting. If a
packet is subject to traffic policing in a policy map and is associated with a VLAN
that is rate limited, the packet is counted only in the traffic policing of the policy
map.
This command does not work in Layer 3 mode. It does not work in conjunction with
IP Source Guard.
Example
The following example limits the rate on VLAN 11 to 150000 kbps or the normal
burst size to 9600 bytes.
switchxxxxxx(config)# rate-limit 11 150000 9600

Configuring rate-limit in switch 6500

Good morning gentlemen
Consider a 6509E (supervisor 720 3B) switch with many interface VLANs configured, one of each related to each customer. Each interface VLAN had configured a rate-limit input and output configured representing the maximum bandwidth permitted for the customer.
I could configured that way using the old IOS s72033-ipservicesk9_wan-mz.122-18.SXF7.
Last weekend I had to upgrade that IOS to s72033-ipservicesk9_wan-mz.122-33.SXJ7. All rate-limits in VLAN interfaces disappeared, probably not supported in this new version.
Now, what's you recommendation to perform the same in this IOS version?...I only found the policy-map/service-policy way.
Follow my questions:
1 - "mls qos" is globally disabled. Should I configure globally or by interface VLAN?... Expected any impact?
I believe that only need "police" for QOS. No need for any other kind of QOS.
2 - Should I enable "mls qos vlan-based" for each physical layer 2 port connected to that switch related to each interface vlan with police?
Expected only one physical port (or port-channel) for each customer (and each VLAN) connected to a switch.
Thank you and regards
Christian

Interesting that I have just upgraded the IOS to the last version 12 release.
I think that for the reason that we are facing high CPU usage for "IP Input" process, something related to mls/cef is not tunned.
Anyone has any idea regarding the configuration presented?
Regards
Christian

Bandwidth rate-limiting on 3550-12T, G and 48 switches

Hi folks,
I'd like to nail-down the raw bandwidth on my switchports to divide a 9Mbit/s uplink between two client groups of 6 & 3Mbits/s respectively ("ring-fencing"). IOS is currently 12.1(14)EA1a and doesn't offer "rate-limit" on the interface in cfg mode. So: (a) can it be easily done on this platform with an IOS u/g? or (b) do I need new hardware?. I note that the 3750's don't support this command in hardware (yet?).
Any help will be appreciated.
Regards,
Andy.

Hello Andy,
You should be able to restrict the bandwidth by per port and or per port/ per vlan on the Catalyst 3550. You are correct there is no rate-limit command on the Catalyst. This is a legacy command used restrict traffic rates. Routers and switches have now implemented this policing feature using the police command. There is a possibility you can gain further feature enhancments with IOS upgrades, but you should also be able to achieve your end result with your current IOS release.
I point you to the following two Cisco documents for the details:
