Traffic shaping/Application restriction question

I have an XServe running 10.4.4. It's currently behind a router on a T1 and that services email (including web mail), file sharing, and FileMaker Pro sharing. I'd like to install a cable modem and attach it to the second ethernet port and use that network connection solely for rsync backups to and from other computers. Is there a way to restrict an application to only one network interface? Thanks in advance for any help.

Shaping and policing can both can be used for outbound traffic on an interface, but only policing can be used for inbound traffic. If you're trying to use shaping (which works by managing the queue) on inbound traffic (which has no manageable queue) it will have no effect. Policing is the only option in this case.

Traffic Shaping on a 2600 router (IOS ver 12.2.31)

I have configured traffic shaping on a Fastethernet subinterface as follows;
f0/0.1
traffic-shape rate 256000 7936 7936 1000
After reviewing the management graphs it looks as though the Traffic Shaping is not working as the graph shows a utilization of 800%. Is there a known reason for this and is there a way I can check on the router. I have ran the show commands but nothing is obvious as to the reason for this. The router is a replacement for a 1721. The same config has been applied. This started happening when the routers were changed.

This is a very vague question, but you may need to add a bandwidth statement to your interface for your application to correctly interpret the utilization.

Hello. I'm trying to restrict SMTP bandwidth to ~640kbit. This should be applied to Se0/0 interface, my device is a Cisco 1760.

When the Exchange server (attached on Fa0/0) starts spitting out mails to the Internet the traffic instantly reaches wirespeed (1mbps), and of course all hell breaks loose (latency, etc). The question is what is wrong with the above config that won't keep SMTP traffic at 640kbit.
I see a "Shaping Active no" there, which doesn't sound good.
I am definitely missing something.
Any help is appreciated, thank you.

Hello Adrian,
there is one strange thing in your show/config given:
class-map match-all match-smtp
match protocol smtp
----snip----
Class-map: match-smtp (match-all)
59977 packets, 83502451 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group 2
----snip----
Why does ACL 2 show up int the show policy-map command, when you have configured NBAR (match protocol smtp)?
Are you sure those two outputs are from the same router with the same config? Can you please highlight the underlying reason for this inconsistency? If not a reboot might help ...
Otherwise you might also leave away the Bc and Be values and just take "shape average 640000".
Hope this helps! Please rate all posts.

Traffic Shaping - can't get it to work

Hi
I’m attempting to create a basic traffic shaping policy in a lab environment but I can’t seem to get it to limit the download rate?
I can successfully achieve this with policing. I am testing the speed restriction using a broadband speed testing website, policing is clearly impacting the download rate, this is not the case with shaping. Please see below the shaping and policing policies, which I am attaching in turn to the vlan1 interface outbound.
Further I have messed around with the below shaping policy and set a fixed cir as in the policing policy but it still has no impact on the download speed.
Finally class SLOW_PC under PM POLICE matches an ACL matching traffic to and from a particular IP address. The speedlimiter is matching all traffic
Policy Map speedlimiter(Shaping)
    Class class-default
      Average Rate Traffic Shaping

Can Anyone Help Me Configure My Verizon (D-Link) DSL-2750B "Traffic Shaping" (QoS)?

Well ... I just spent a wonderful hour and a half (not) bouncing around VZ technical support, etc. trying to get assistance regarding configuring my DSL router.* Between the low-quality Skype connection to India and my lack of success, I'm a little bummed out right now.
Could one of you perhaps help me? I'm trying to configure a single, wire-attached network node (port 4 of the router) so that it can only consume up to 320 Kbps of my 750 Kbps (7.5 Mbps) DSL bandwidth ... no matter what. This results from this node consuming virtually all of the circuit's bandwidth when streaming or during bulk file transfers.
I have tried to remedy the problem using priority with no discernible impact.
The Quality of Service (QoS) element called Traffic Shaping (Services | QoS | Traffic Shaping), described on Page 51 of the VZ DSL-2750B User Manual , appears to be the ideal solution to my problem. Repeated attempts at activating this QoS have all resulted in no throttling of bandwidth consumption.
My most recent attempt was to define the device on Port 4 as the DMZ host ... and then apply a new rule (320 TX, 320 RX) to this interface. Again, no joy.
Does anyone have any experience with this service on this router?
Am I chasing my tail trying to configure the router without validating that my circuit is not configured with "Fastpath (PSE) inactive"?
If the circuit configuration is a potential problem, which office should I ask for at VZ customer service?
Here is the information from the System page of the Router Control Panel:
Gateway ID: PX2M1BC000000
Software Version: 5.4.12.1.44
Release Date: Feb 19 2012
Platform: D-Link DSL-2750B
Board Tag:... Ntag-5_4_12_1_44
Compilation Flags:... LIC=/home/bat/bat/dlink_bcm96328_5_4_12_1/20120219_1343/conf/jpkg_bcm9636x_dlink.lic CONFIG_RG_PROD_IMG=y DIST=DLINK_DSL2750B
I'll note that the Router provides a notification that "RX QOS might not operate when Fastpath (PSE) is active" when I update the router configuration page concerning Traffic Shaping. Because Fastpath is not mentioned in the User Manual, I'm guessing that Fastpath (PSE) might be a configurable attribute of the circuit servicing my PoP, but I have no idea if this is the case.
I searched for relevant messages on this board ... without success. If this has already been addressed, please provide a link, and accept my apologies. (My Google-Fu tends to be weak.)

The asterisk in the first post refers to the following summary of events:
10:40 - Attempt to solve my configuration question using VZ chat begins.
10:49 - VZ chat agent Danish refers me to phone support. (Chat ID number is 020813176471 if you're with VZ and are interested.)
10:50 - Call VZ phone support.
11:02 - Talk with Angel. Because she has not heard of, nor received training in, "traffic shaping," she says my question about configuring this VZ DSL modem must be addressed by "Premium Technical Support." She transfers me.
11:13 - Talk with Pamela. Premium Technical Support only responds to questions about 3d party products. Because my question concerns a VZ DSL modem, Basic Technical Support is responsible. She transfers me.
11:17 - Talk with Joe. He says either the vendor (D-Link) or premium technical support is required. Because I had already tried with D-Link (they referred me to Verizon, as this modem was built exclusively for VZ), I explained what I had already experienced, and described how I wanted "assistance configuring my VZ DSL modem, specifically a feature described on page 51 of the User Manual." He transfers me.
11:23 - The automated phone system asks for my 12-digit customer ID. I wasn't able to find it fast enough, and rolled through to Financial Services. Eventually Trig picked up, listened to my story, and transferred me to "Technical Support" providing the direct dial number, just in case (866.945.79xx).
11:32 - Entered the phone queue. Lots of hissing and clicks.
11:35 - Talk with Monika. (The voice clarity from this point onward was on the order of 1st-generation Skype. Between the horrible language problem -- Monika is in India don'cha know -- and the lousy line quality, this was the most frustrating.) No matter what I said, I couldn't convey the reason for my call. I asked to talk with a supervisor, which Monika related was not possible. She also related that she could not transfer me to an American POC or supervisor.
12:01 - Hung up the phone ... and started down the path that led to my post immediately above.
I was repeatedly queried about the account name and number throughout the process. Conveying this information was especially challenging during the Indian call segment.

=====================================================
Hi everyone,
In the above configuration, I configured traffic shaping to shape the syslog traffic to certain limit. My question is, Can I apply traffic shaping to perticular traffic ? What will happen to the remaining traffic ? We have ethernet hand-of to provider but total bandwidth we can use is 8M, which is controlled by ISP. We just send all the traffic without any shaping.
Thanks

Traffic shaping only works from the source. there is no way (other than policing - i.e., discard) to shape through the cloud.
If you tried to pace the traffic through the cloud, it's got to be buffered somewhere, causing latency, and ultimately discarded frames after the buffers fill.
Policing allows the traffic through until some threshold occurs (traditional frame = DE set at Bc, discard at Be), then the traffic is dropped.
FWIW

Traffic shaping: Which is the best solution?

Hi! I'm running 3 computers on 1 d-link router, 2 of them has an archlinux installed. Wondershaper mostly works for me when the other computers has cfosspeed running on windows, but when both computers run archlinux and wshaper and p2p applications, ping is over 1000ms instead of 10-20ms.
Which is the best solution of traffic shaping on linux, and is there a howto for them (can be even a gentoo wiki page or similar)?
Edit: shorewall is not being built from yaourt (x86_64), can't find a usable manual for trickle and niceshaper, (even ubuntu forums has unreplied "threads" about it) and can't start them coz missing config files, it seems, noone cares about ACK priority and ping in the Linux world
Last edited by Vegita (2010-02-24 19:58:07)

This config file is being used on 2 computers, and not working, my speed is 8m/1m. Any ideas? I don't want to limit anything, I just want ACK's priority to set to the highest, and same with http, and get p2p apps (opn this computer ktorrent and valknut, on the other ktorrent) priority on lowest. valknut's port is 1412, ktorrents' one is 6881 on this and 24748 on the other computer. Any ideas what to modify for small ping?

QoS Traffic shaping and peak shaping

Hi,
Could somebody tell me what is the difference between traffic shaping and peak shaping?
Kind Regards.

Standard traffic shaping (the shape average command) will keep the average rate of the traffic to the limit you specify, which should be the committed rate of your circuit.
Peak shaping will also do traffic shaping (using queues, etc), guaranteeing a minimum rate, but will allow traffic to levels to burst above your configured (committed) rate.
From the documentation:
Traffic shaping limits the rate of transmission of data. In addition to using a specifically configured transmission rate, you can use Generic Traffic Shaping (GTS) to specify a derived transmission rate based on the level of congestion.
You can specify two types of traffic shaping; average rate shaping and peak rate shaping. Average rate shaping limits the transmission rate to the CIR. Using the CIR ensures that the average amount of traffic being sent conforms to the rate expected by the network.
Peak rate shaping configures the router to send more traffic than the CIR. To determine the peak rate, the router uses the following formula:
peak rate = CIR(1 + Be / Bc)
where:
â¢Be is the Excess Burst size.
â¢Bc is the Committed Burst size.
Peak rate shaping allows the router to burst higher than average rate shaping. However, using peak rate shaping, the traffic sent above the CIR (the delta) could be dropped if the network becomes congested.
If your network has additional bandwidth available (over the provisioned CIR) and the application or class can tolerate occasional packet loss, that extra bandwidth can be exploited through the use of peak rate shaping. However, there may be occasional packet drops when network congestion occurs. If the traffic being sent to the network must strictly conform to the configured network provisioned CIR, then you should use average traffic shaping.
Examples
The following example sets the uses average rate shaping to ensure a bandwidth of 256 kbps:
shape average 256000
The following example uses peak rate shaping to ensure a bandwidth of 300 kbps but allow throughput up to 512 kbps if enough bandwidth is available on the interface:
bandwidth 300
shape peak 512000

MPLS Traffic Shaping/Policing on PE-CE link

Hi everyone,
We are considering to upgrade our remote sites to MPLS/VPN type of connectivity from ATM/FRASI.
Lets say we take a 10Mb link in the main office and 2-4Mb links for remote sites. Majority of servers (services) reside in main site, so majority of traffic flow will be from main site to remote sites.
1. Since CE at main site sees all the remote sites "coming" from provider's PE, how can you handle traffic shaping/policing issues on this main site CE?
2. Do you use MQC based on destination IP to apply shaping/policing configs on the CE-PE interface?
3. Is it necessary to even bother with this question?
Thank a lot.
David

BGP contains a multitude of knobs which allow a SP to control the traffic sent on one PE-CE link as opposed to the other. One can also make use of the Link Bandwidth extended community to control how traffic is distributed among multiple egress PE-CE links.
The VPN scheme is of course compatible with the use of traffic engineering techniques (RSVP-TE based or otherwise) in the backbone network.
A PE may support additional QoS support by means of one or more of the following methods:
-i. One COS per PW End Service (PWES), mapped to a single COS PW at the PSN.
-ii. Multiple COS per PWES mapped to a single PW with multiple COS at the PSN.
-iii. Multiple COS per PWES mapped to multiple PWs at the PSN.

Show CDP from the switch is not discovering devices, but the neightbors can see the 5K in question. Reboot sometimes will fix it, but not always.

QoS Class-Based Traffic Shaping (what is Be)

Guys,
two questions on the output below :
1. What is the Be, is this an amount per interval that can go over Bc or is it the total amount of data that can be sent?
ie, i interpret the command to read, Bc is the sustained rate per interval and Be is the sustained rate plus another amount, it I would use sommat like this
shape average 128000 7936 8500
this would show that I could send in total up to 8500 bits per interval
or does it work like this ?
shape average 128000 7936 564
this would show that I could send in total up to 8500 bits per interval
if it is the first one, you would not expect to be able to configure a Be of less than Bc?
Also, how can you show what traffic is within the Bc and what is in the Be? ie, how much data is being sent out of contract?
Many kind regards,
Ken

Guys,
this is great stuff and I really apprciate it.
The thing is this.
One one URL it says the following :-
For Class-based Shaping - How it Works
When the Be size equals 0, the interface sends no more than the burst size every interval, achieving an average rate no higher than the mean rate. However, when the Be size is greater than 0, the interface can send as many as Bc + Be bits in a burst, if in a previous time period the maximum amount was not sent. Whenever less than the burst size is sent during an interval, the remaining number of bits, up to the Be size, can be used to send more than the burst size in a later interval.
The other URL says :-
DTS How It Works
The Be size allows more than the Bc size to be sent during a time interval under certain conditions. Therefore, DTS provides two types of shape commands: average and peak. When shape average is configured, the interface sends no more than the Bc size for each interval, achieving an average rate no higher than the CIR. When the shape peak command is configured, the interface sends Bc plus Be bits in each interval.
So which one is correct. I am really confused.
As far as I am aware, I am running CB Shaping and not DTS, but when I go into the router configurations I get both options.
average and peak ?
Please see example :-
Metro2(config)#policy-map test1_cos
Metro2(config-pmap)#class class-default
Metro2(config-pmap-c)#shap ?

Skype for business traffic shaping

Good morning,
I would like to implement Skype Business in my company. We are an international company with contacts in India, Tanzania, Canada and so on... so normal Skype connections are really bad in some countries because of the bandwith they have.
I have seen the reviews of Skype Business, my question would be, how can i implement a nice traffic shaping for setting up all? I have access to all hardware in all the offices we have but i would need more help about
Thanks in advance,
Kind regards

Hello Celia,
I see you are wanting to implement Skype through out your network for making calls via Skype. This is very easy to do, as long as you have Internet access at all locations. The only thiing I see is that the Internet Connections you have may not be up to our standards.
The first thing that needs to be done is to run a Traffic Study in each location to determine the quality of the Internet Connection you need. The simplest way is to run a Voxygen test at each site. You can have someone at each site log into Voxygen at https://tools.voxygen.co.uk and run the Network Compability Test for Skype. This test will display results after each test to give you recommendations on what you need to have to connect to us. It will test for up to 50 Channels.
The next action is to determine what type of equipment you will need at each location. For that answer, you should contact your IT department for recommendations.
If you need PBX's or any other type of equipment, Skype can make recommendations via our web site. http://www.skype.com/intl/en-us/business/skype-connect/
From there you will need to have a Telecom person help you implement your network to connect to Skype. Start small to test, then build from there.
I hope we have answered some of your questions to get you started with Skype Connect. We are here for your support, so come back anytime.
Thank You for considering Skype and using the Skype Community Forums.

Traffic shaping G723 traffic between 2 companies

Hi,
Can someone put me on the right way to implement traffic shaping (QoS) for G723 traffic.
Situation:
Two companies connected to each other with a vpn tunnel. The hardware is Cisco 2621xm at the sublocation and on the hq location is an 2651XM.
There is an GRE tunnel configured between the two sites. The GRE tunnel is up and working.
On both sites there is an telephony system that can use G723 anr/or G711. Both telephony systems are connected to each other.
Voice is working, but now we want to implement QoS for the VOIP connection.
Has someone suggestions for me ?

Hi,
Appy a policy-map with the desired QoS policy to the tunnel interface.
First of all, issue 'qos pre-classify' on the the tunnel itself, otherwise the congestion management mechanism will be useless.
Cheers,
Gabriel

Traffic shaping for the Mac

Some routers offer a traffic shaping option to keep uploads from slowing down downloads on asynchronus connections. The Airport Express doesn't? Any software to do it on the Mac?

No the AirPort Express (AX) does not have this feature.
Any software to do it on the Mac?
Of course that would only affect traffic to/from that one specific Mac. You might want to take a look at IPNetTunerX.
