Setting dynamic rate limit
I would like to know how to set the dynamic rate limit on the wan and the lan on the spa2102 voip adapter. can anyone help?
There is no such function on any of the SPA2xxx or SPA3xxx series voice router.

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

9. Transaction OB01
Credit management/Change risk category
Definition of the risk category for each credit control area. This risk category can be
assigned to a credit account by using Transaction FD32.
10. Transaction OVA8
Here, the individual credit checks for key fields
o credit control area
o risk category
o credit group are set. Take these key fields from the above settings and go to the detail
screen. In particular, check whether fields "Reaction" and "Status/block" are set
correctly. To carry out follow-up actions in case of a credit block, the credit check
status must be set (field "Status/block").
11. Transaction FD32
Credit master data for the payer of the relevant document.
Credit account:
Credit limit:
Risk category:
Currency:
12. Settings for updating the credit values Update of the credit values is required for the limit
check (static or dynamic credit limit check).
13. Transaction OVA7
Update of the credit value is active for the corresponding item type if the check box is marked. This field corresponds to
field "Active receivable" in Transaction VOV7.
Item type:
Active receivable:
14. Transaction V/08, Pricing
In the pricing procedure used for pricing, subtotal "A" must be entered in a line for
determining the credit value (mark the pricing procedure and doubleclick on "Control").
Usually, the net value plus taxes is used. This way the system is determined to use this
subtotal for credit pricing. The credit price is stored in field VBAP-CMPRE and used for
update and credit check.
You can find the used pricing procedure of the order under "Item -> Condition -> Analysis".
Pricing procedure:
Line with subtotal = 'A':
15. Transaction OB45
Which update group (field "Update") do you use in the relevant credit control area? The
default setting is "12". If you use another update group, check whether this is fine with
you. If you open an OSS message, please tell us the alternative update group.
Credit control area:
Update:
16. Transaction OMO1
Which kind of update did you choose for structure S066?
In any case, "Synchronous update (1)" has to be chosen as the kind of update.
All other settings will lead to errors.

Dynamically set the upper limit of a numerical control
I want to dynamically setting the upper limit of a numerical control. The maximal value that is allowed to input is calculated by the code, so that if the value input by the user exceeds the upperlimit, a warning comes out and the input value is automaticaly reset to zero.
I wired the calculated upper-limit to the property node of the numerical control using ''Data Range > Maximum" property, but it does not work as I expected.
Anyone has suggestion on this? Thanks a lot.Can you attach your code?
Dejun wrote:

I cannot read your mind. What do you expect? What to you see instead?
Overall, you are in a catch22 scenario if I understand you right. If you set the max of the control to coerce to a certain value and you enter a larger value, it will be coerced to the upper limit and the code does not see the original out-of-range value and you cannot successfully test it with a comparison operation. Maybe you can set it to "ignore" instead of "coerce" or not even set an upper limit. Simply use "in range and coerce" and reset the value under the desired conditions (e.g. via a local variable) before handing it to the rest of the code. You could even wrap this into an xcontrol.

Dynamic setting of error limit
Hi All
Is it possible to set dynamically the "maximum error limit" of an interface . The client has a requirement where the error limit will be provided from an external file / table and the value from the file should be used as a parameter to stop the interface when the errors reach the percentage limit.
ThanksHi,
Trying to Help!
I don't know whether there is any such kind of built in feature in ODI or not. But Surely such kind of Functionality can be delivered by adding another option in CKM such that it will accept some numbers as parameter and when it exceeds the no, abort should take place.

Dynamic ARP inspection rate limit issues with Windows Vista Systems
Good Day to everybody.
I had implemented DHCP Snooping & Dynamic ARP inspection feature to mitigate ARP spoofing attacks to one of customer location where we have mix of Windows vista & XP systems. By default DAI feature rate limit ARP packets on un-trusted ports to 15 Packets per second. With this value I was facing some issue to access file shares where port will go in error-disabled state due to ARP broadcast from system was crossing 15 PPS limit of DAI. For the same, I had increased the DAI limit to 64 & after that we had not facing this problem from windows XP systems, but windows vista systems are still giving problem. Also this probem is very random in nature & not all the windows Vista system will face same issue even though they are accessing same file share & are configured with same DAI rate limit.
That's why I am not able to figure out baseline values for DAI rate limits. I had already search microsoft documentation for limiting this ARP broadcast from Windows Vista system, but no luck.
Is there any way to find out correct settings for this DAI packet rate limiting in Windows Vista enviorement ?Hello bensyseng,
check out this thread.
As topmahof said already it could correlate with a wrong Intel driver.

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

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. -
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,
DHello,
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

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. -
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 attachedStruggling 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,

Hi All - I need your help to understand the Burst value in the Rate-Limit
Example: rate-limit input access-group 101 20000000 24000 32000
I understand the above configuration limit the traffic to 20Mbps. How to calculate the Burst-Normal (as per example above 24000 Bytes) and Burst-Max(as per above example 32000 Bytes). What is the logic for arriving the Burst-Normal & Burst-Max?
Thanks in advance
SAIRAMHi Sairam,
below are definitions of few terms which are involved here
CIR : committed information rate, in bits per second, defines the rate defined in the traffic contract.
Tc : Time interval,measured in miliseconds, over which the committed burst (Bc) can be sent.
Bc : Committed burst size,measured in bits. This is the amount of traffic that can be sent over the interval Tc.
Be : Excess burst size, in bits. This is number of bits beyond Bc that can sent after a period of inactivity.
Formula to calculate Bc is
Bc = CIR*Tc
Now to understand Bc and Tc, say suppose you have applied 20mbps rate-limit on a 100mbps fastethernet link. Now link can send data (bits) with clock-rate only which is 100mbps so to achieve 20mbps rate on that link router needs to send traffic for 1/5th of a sec and remain idle for 4/5th of a second. 1/5th of sec is 200 msec. If router will send traffic for 200msec and not sending traffic for next 800msec, it can achieve rate of 20mbps but a packet arrived at 199th sec will need to wait for 800msec and this will add unnecessary latency to the packet. To avoid this, router sends few bits for short duration and then does not send for some duration. For the period it sends traffic is called Tc value. and the number of bytes it can send during that interval is called Bc value. So CIR = Bc/Tc (bits per interval).
Now we dont have option to configure Tc but we can configure CIR and Bc, and Tc will automatically be calculated. If we do not configure Bc then router takes default Tc of 125ms and calculates the Bc.
What value to choose for Bc
If we configure Bc too large then Tc will go high for same CIR and this may cause delay or jitter for delay sensitive traffic. For delay sensitive traffic cisco recommends to have Tc 10ms or less.
If i calculate Tc in the given example, it is coming as 9.6ms which is close to 10ms that is why Bc is set as 24000.
Tc = Bc/CIR
= 24000(bytes)/20000000(bits/sec)
= 192000(bits)/20000(bits/ms)
= 192/20
= 9.6 msec
Now Be is to give extra bandwidth for small interval(Tc) to cater some bursty traffic. Assume there is a bucket which gets filled with Bc amount of token in every Tc interval and router can send traffic if there is sufficient amount of token available in the bucket, equal to the packet size. After forwarding packet router reduces same amount of token from the bucket. Size of bucket is also equal to Bc which means if there is no traffic for Tc interval, bucket can not hold more token. Be is to increase the size of bucket to (Bc + Be). Now in every Tc interval bucket will be filled with Bc token and if there is a period of inactivity then in next interval bucket can be filled with extra Bc amount of token till it reaches to (Bc + Be) and if there is any bursty traffic (more than Bc) same can be adjusted. So for a very small period router may send traffic with more rate (higher than CIR, since sending Bc+Be in Tc interval) but over a period does not cross CIR.

Rate-limit for some MAC on aironet 1231
Hello!
I need to set rate-limit for some mac addresses on access point aironet 1231.Is it possible?
If no, what ios or devices can do it?
Thanks.No there is no option for rate-limit in Aironet but in controller, Rate-limiting is applicable to all traffic destined to the CPU from either direction (wireless or wired). Cisco recommends that you always run the controller with the default config advanced rate enable command in effect in order to rate-limit traffic to the controller and protect against denial-of-service (DoS) attacks. You can use the config advanced rate disable command to stop rate-limiting of Internet Control Message Protocol (ICMP) echo responses for testing purposes.

Hello friends,
I have a problem; now i'm changing the router that have at work of Cisco 3925 to Cisco ISR 4451X but in the new router i can't put the command that have in my old router:
rate-limit input access-group 110 16384000 3072000 6144000 conform-action transmit exceed-action drop
Can someone help me telling what command replace it or which is the equivalent?
Atte.
PercyEdison,
Thanks for helping with this it is greatly appreciated. I have been playing around with this and have managed to get the policing working successfully on the SVI.
The problem was basically the direction the policing was being applied. Initially I was applying the service policies to the customer SVIs in an inbound direction. This would only be traffic coming into the VLAN interface from within the VLAN; therefore, in terms of internet traffic this would be upload and NOT the required download.
In order to resolve this, I have applied the service policy to the Internet facing VLAN. Please see below -
Class Maps and Policy Maps
class-map match-all CUST-A-VL10-CMAP1
match input-interface FastEthernet1/0/24
class-map match-all CUST-A-VL10-CMAP2
match access-group name CUST-A-VL10-ACL-POL
policy-map CUST-A-VL10-PMAP1
class CUST-A-VL10-CMAP1
police 100000 18750 exceed-action drop
policy-map CUST-A-VL10-PARENT-PMAP1
class CUST-A-VL10-CMAP2
set ip precedence 1
service-policy CUST-A-VL10-PMAP1
VLAN Confguration
interface Vlan300
ip address ************
service-policy input CUST-A-VL10-PARENT-PMAP1
This works successfully and polices the traffic as expected. However, I have now run into the problem with assigning multiple service policies to the VLAN interface. As this is the internet facing VLAN for the routing of traffic to and from the internet, all customer service policies need to be applied to this interface. When I attempt to apply more than one service policy to this VLAN i receive the following error -
(config-if)#service-policy input CUST-B-VL20-PARENT-PMAP1
Policy map CUST-A-VL10-PARENT-PMAP1 is already attached
Looks like another couple of hours needed working around this problem!!
Thanks

Hi, I have someone who is worried about denial-of-service attacks. They have 11 vm's that share a connection and want to set it up so that there is a maximum amount of traffic allowed to hit each vm, so if there is a DDoS attack it will only affect that one VM instead of all the VM's on the same connection. What is the best way to go about this from the ASA? This is behind a 5515 with asa code version 8.6. Is there a way to rate-limit by ip address? Thanks!
The feature is called traffic policing. Basically, what you should do is this:
1. Define traffic to each server by using corresponding ACLs
2. Define class map for each server
3. Define policy map or use global policy to apply policing.
Example:
server 1 has ip 10.0.0.1 and provides http access from the outside
server 2 has ip 10.0.0.2 and provides https access from the outside
1.
access-list SERVER_1_TRAFFIC permit tcp any host 10.0.0.1 eq 80
access-list SERVER_2_TRAFFIC permit tcp any host 10.0.0.2 eq 443
2.
class-map SERVER1
match access-list SERVER_1_TRAFFIC
class-map SERVER2
match access-list SERVER_2_TRAFFIC
3.
policy-map global_policy
class SERVER1
police input 100000 (bps) 10000 (bps)
police output .....
class SERVER2
police input 200000 (bps) 10000 (bps)
police output .....
