Discussion on:

Configure QoS on your Cisco router with this template

Hello to All,

What do you think of the template?

Can you see where you could use this in other situations? How could it help you to do other things?

Thanks for reading TechRepublic!

-David Davis

I've been waiting for this article. I'm ordering Packet 8 VOIP and I'll try out your template and give my feed back.

What will we be covering next in the 871w tutorial? Easy VPN for Cisco 871w (windows Client to 871w router connection). I've been try to find an article on how to configure this from CLI, but no success yet. Keep up the good work.

Here you go, exactly what you're looking for on Cisco IPSEC, but that's for site-to-site VPN tunnels. We'll have to create one as a VPN server template.

We're also going to do some stuff on 802.1x.

Does not work with the OS X version of Office 2004. I have
not tried it in Open Office, but it looks like this feature will
be a Windows only feature. Cannot click on the button. You
can see the button, and when you mouse over it you get a
hand to click on the button, but you cannot actually click
on the button. Macros were enabled.

We didn't expect it not to work on Mac Office 2004.

Hi

I saw your info on www:\\techtrpublic sit and your info are very helpful.. I jest need to have the commands. If you have the commands for configuring Qos please email it to me. I work for a school in New York City.


Thank you for your consideration.

Sincerely

hi
i have c2821, he is connected to 2 diferent ISP. i mark priority traffic from ISP, and apply policy on inside interface (vlan).
results wasn't as i like to be.
than i try with you template, results are the some.
my question is, how to debug or verify does qos policy is ok or not.
best regards

show policy-map inter
which will give the reseult whether the QoS is applied in the interface or not

Hello, I have Ciscos 2500 with IOS 11.0 does it work for me ?
thanks in advance

Great work David,

...But apparently 'ip nbar protocol-discovery' is not supported on 4948s I am running. Wonder how I could enable priority on SIP and RTP protocols without having NBAR on my router...?

Thanks,

I am using the template for creating my QoS. But I need to load balance over multiple Internet links. Can you tell me how this is done. We are currently using static routes.

Great article and template! I have one question though: does the created policy also control inbound traffic as well? I see that the template applies the policy as 'output' on the WAN facing interface.

no, because as david explained on the attachment "We can only perform QoS on the traffic that we send, NOT the traffic we receive."

Please, Can you help? I need for configuring QoS on Cisco 1600, to VoIP and Video

like to know abt qos

Hi i need your help for configuring QoS on cisco 2500

I have a switch that I want to configure Qos and I would like to know how can i use the template for the switch, my bandwidth is of 14Mbps ???

Dear David,

First I would like to thank you for your post it is very helpfull.

But till now I try to find a way to fix this issue:
I have Ciscao 7200, 12Mbps down and 10Mbps up
I use VoIP (SIP server), now I the Quality of voice is worst and I want to limit the bandwidth for all packet except SIP.

Best regards.

Hi,
My router (c870-advsecurityk9-mz.124-9.T.bin) does not recognize "skype" in the following command:
match protocol skype
Do I need any a different IOS version?

Hi,
I would like to check with you that : do i need to configure cisco switches for LLQ /QoS?

My requirement is simpler, actually, but never having used QoS, I'm confused.
I have 2 Cisco 2800 routers (IOS 12.4(15)T5 on one (R1) and 12.4 (18)b on the other(R2)).
The PRI is attached to R2
I have an Engage IP Tube attached to the 3m link between the 2 routers and a Voice T1 plugged into each IP Tube. We are getting echoing and broken up speech on the outbound side of R1. I believe Qos may solve the issue, but have no idea how to configure. Can you help?
Thanks,
John

I realize this is an old article, but in case anyone else is trying to get this working on an 871 and having trouble, here is something I worked out after much trial and error.

In order to get effective QOS for my IP phone (as in pick up the phone and it takes bandwidth/queue position away from anything else happening on the network sufficiently to have ZERO sound quality issues) I had to add a simple traffic shaping policy in addition to the steps listed in the article for making a qos policy.

So, follow the article/spreadsheet with one change: instead of applying the qos policy directly to the outbound interface (i.e. service-policy output MyQOSwhatever), make a traffic shaping policy that references the qos policy and apply that:

(make a shaper)

policy-map shaper
class class-default
shape peak 150000 -- find a number/method that works for you
service-policy MyQOSwhatever

(apply this instead)

interface FastEthernet4
service-policy output shaper


Maybe there is a way to avoid needing this, I am no cisco expert. Maybe my situation is a bit different because I use a PPPoE connection for outbound... all I know is that without a shaper, things were better than nothing but still far from perfect. With shaper, I have perfect sound quality on calls no matter what else is going on the network. hope that saves someone some time.

It has a spelling mistake in the auto config.

You have written

when it needs to be

Does not work on the office suite for the mac!

This might be helpful. Can you help me to configure QoS on 1841 router?

Hi,
Could you please to explain, why the QoS policy is applied to outward direction ?
While the biggest traffic when we are downloading file is on inward direction.
Don't we need to manage/apply inward direction also ?

thanks.

I need help, I have traffic internet traffic via port no 12307 and data traffic, i want to configure the router to give say 90 percent priority to data traffic to avoid internet congesting the link. please assist me via mtituh@yahoo.com

Lets say that an ISP has Cable modem customers and Fiber based customers, and they have a 200Mb backbone which is getting congested. How would they setup QOS for the Fiber based customers to have priority on all traffic traversing the link, with everyone else having a fair chance for what is left....?

Anyone else have this problem? Keeps putting me back to the profile page. EDIT: It was FireFox. Problem Solved!

I get this error log when i try to load the template. What do I do?

- error071480_02.xml Errors were detected in file 'C:\Users\felix\Downloads\ddavis_QoS_worksheet.xls' - This workbook has lost its VBA project, ActiveX controls and any other programmability-related features.

Hello, I have a VSS 4560 Switches on a Site 1, and a 7200 on SIte 2. I need to configure QoS for VoIP traffic between the 2 Sites. I applied this configuretion on each port of the access swiches 3560 POE :
switchport priority extend trust
mls qos trust cos
switchport voice vlan dot1p
switchport access vlan x
switchport mode access
switchport voice vlan 173

The problem for me is this: the configuration above is for Layer 2 QoS with 802.1p, I need to know how to configure QoS on layer 3 so that the Layer 2 configuration is translated on layer 3 while packets are sent between the 7200 on Site 1 and the VSS switches 4560 on Site 2!
Can you help me please?
