QoS Settings to Match SP Policer

Hi,
My SP has an ingress policer specifying 100mbps CIR and 256kbps Bc.
When I try to configure a shaper to match this requirement, I cannot specify a Bc value smaller than 400000, as the Tc cannot be less than 4ms. For example,
OFFICE-01(config-pmap-c)#policy-map policy-map QoS-Outbound-100M
OFFICE-01(config-pmap-c)#class class-default
OFFICE-01(config-pmap-c)#shaper average 100000000 265000
Shaping Interval is 3 milliseconds. Intervals below 4 milliseconds rejected.
If I use the minimum Bc value of 400000bps, traffic might be dropped by the SP. Any workaround? The major application in the network is http.
Thanks.
Larry

Bc isn't a per second value, it's a quantity of bits or bytes.
Also, Bc might be given in bytes, so double check whether your ISP's value is 256 KBytes or Kbits.

Understanding QoS settings

In order for networking device to classify traffic, there is certain information within a frame or packet to identify the importance of a frame or packet. CoS, IP Precedence, and DSCP are widely used nowadays.
CoS is in layer 2. IP Precedence and DSCP are in IP header.
In a dot1q tag, there are 3 bit used to identify the importance of the frame. As CoS is 3-bit, the range is between 0 to 7. In normal Cisco VOIP implementation, Cisco IP phones mark CoS 5 on RTP frames. Data traffic is put on native VLAN; so that there is no 802.1q tag on data traffic. By default, Cisco switches put any traffic without 802.1q to be CoS 0 and DSCP 0.
Before DSCP is used, the second byte in IP header is called ToS (Type of Service). It was used to classify IP traffic. Like CoS, IP precedence is 3 bits. Thus, the range for IP precedence is 0 to 7. After a while, we find out that 3 bit is not long enough. We expand IP precedence from 3 bites to 6 bits. It is called DSCP. As DSCP is 6 bits, the range is 0 to 63. Normally, Cisco IP phones mark EF (DSCP value 46) on RTP packets.
QoS on campus switching is different than router. In router, we normally mark and police the traffic just before going to ISP. As a result, you determine what traffic is dropped if the traffic going to ISP exceeds the bandwidth of the circuit.
We normally classify traffic on ports connecting to phones and end devices. To simplify configuration, Cisco switches allow you to trust CoS; so that VOIP traffic is classify with CoS 5. Different switches have difference queues. However, all Cisco switches put CoS 5 or DSCP 46 into priority queue. Once traffic is classified on the access switches, we can simply trust DSCP or CoS on the links between switches. We should use trust DSCP on any layer 3 links. Also, make sure that voice VLAN is not used as native VLAN.
The last question is what happens if a users put a data device on the voice VLAN and construst frames with CoS 5. Here comes extended trust. Switches have to receive CDP on the port before trusting the device on the voice VLAN is a VOIP phone. Not sure if I miss anything.

WRT600N QoS settings do not affect upstream rates

I have recently purchased a WRT600N router as I have a hard wired wired VoIP phone (Aastra 9112i). I have set the QoS priority for the physical Ethernet port that the phone connects to as high and all of the other ports as normal (I have even tried setting all of the other ports to low).
The problem I have is that the QoS settings do not affect the upstream rate. I have Shaw Highspeed Extreme service and have run speed tests to Speedtest.net throught the router and can get 20Meg down and ~1 meg up. When I change the QoS settings on the physical Ethernet port my laptop is connected to, the QoS settings do affect the download rate but the QoS settings do not seem to affect the upstream rate.
Is there any firmware update for the WRT600N where the QoS setting will control/ throttle the upstream rate or is there some other settings I could use on the WRT600N that will provide priority to my VoIP phone.
Thanks,

I just checked the Linksys download page and the firmware version posted there 1.01.35 is the same version I have in my router. Please let me know if there are any development plans for the WRT600N QoS controls so the the QoS setting also police the upstream/ upload rates.
Thanks,

X3500 QoS settings -- do they do anything?

Hi,
I've had an X3500 for a few weeks, and while it's functioned reasonably well I've been generally disappointed at the quality of the firmware (v1.0.0 build 18). One problem I'm having is with the QoS settings:
whenever I change something and click 'save', my wireless connection drops pat
nothing I do on the QoS page seems to have any effect on traffic patterns
I've tried every combination of settings to prioritise traffic for particular applications (including all three QoS types on the 'setup' page), but none of them have any effect. At times of high load, traffic does not seem to be prioritised in any way.
Has anyone managed to get any measurable results out of the QoS settings?

I see what you're saying, but the wireless drop is at the data link layer: all the wireless clients actually disconnect from the network, rather than simply being throttled or being unable to pass traffic. It's as if the access point has re-initialised and dropped all connections. Sadly nothing useful is written to the log when this happens apart from the DHCP requests as the clients reconnect.
I've tried high- and low-throughput devices, wired and wireless, WMM on and off, and all three QoS types, but I'm unable to detect any effect at times of high load.

HT4913 When I go to Settings- Music and slide ITunes Match to Off, it still appears as On under ITunes and App Stores in the Settings menu. Once I turn this off, on returning to the Music menu under Settings, ITunes Match still shows as on. What to do?

When I go to Settings->Music and slide ITunes Match to Off, it still appears as On under ITunes and App Stores in the Settings menu. Once I turn this off, on returning to the Music menu under Settings, ITunes Match still shows as on. What to do?

I (though am not sure what happened) solved the problem. Under show all I had both videos and music selected as on. I turned off videos and ..hey presto..the slider reappeared.

About QOS Settings with WRt120N router~HELP~

I have a question with the QOS settings, after I set the Priority for my 4 devices via MAC address, including 1 xbox, 2 notebooks and 1 PC with usb wireless adapter. Xbox has the high, and the others are medium. Here is the problem, after I activate the QOS settings, the network on the 2 notebooks and PC is slow.Not entirely slow, but when I try to open a web page, it takes longer time.About the XBOX,I am not sure about its reaction. Please help me out.

Well as you have setup a High Priority for your XBOX under QoS, whenever your XBOX is turned On, Your Router will provide a Maximum Bandwidth of your Internet to your XBOX and it will slower down your Other Devices on your Network.
As you have so many devices in your Network, so i would suggest you not to use QoS Serivce... Or else if you want to use it then you can Turn Off your XBOX whenever you are going to use other Devices ( Computers).

Hi,
is it possible to manage QOS settings on BT Home Hub?

so I understand that there's no chance to put my dirty hands on these settings with my BT home hub 2.0

"Change sequence settings to match clip settings"

Hi - I seem to have lost this prompt!!
Before when I bring a clip into a sequence with a different codec, FCP would ask me if I would like to change the sequence settings to match the clip settings..
I used to love this feature because it meant I didnt need to render the sequence and i could edit clips with most any codec/compression settings etc.
Anyway now FCP doesnt do it anymore! I send the clip down and it just puts it in the sequence and gives me the big RED BAR on top and I have to render.
I have repaired permissions. I have trashed FCP prefs..etc
I'm using FCP 6.0.4 on Tiger. Any ideas would be super appreciated!

Hey guys,
I found the same problem occurred with my own "weird codec". I'm on FCP 6.0.6 and I was doing some simple testing work with Photobooth's video feature, which records in MPEG-4 640x480 .mov. I tried getting my sequence to auto-conform with both 'ASK' and 'Always' settings, but no dice.
I didn't find a solution, mostly because it was easier to simply batch export them all as DV Pal clips, but I thought you might be interested. I posit the auto conform only works with more conventional video codecs like those listed in the Easy Setup options - of which, MPEG-4 is not.

Changing sequence settings to match clip settings-which settings are right?

I'm using a Canon HF10 camcorder and FCS 2 with a 24" iMac Intel Duo core.
When I bring in a video clip shot on my Canon HF10 (I shoot in its highest-quality mode: FXP and I do not use the 24 fps setting), I take FCP 6's recommendation to set the Sequence Settings to match the clip settings. If I then go to Sequence> Settings, I see that my Sequence Settings are 1920 x 1080 HDTV 1080i (16:9).
If you look at the Canon web page for my camera: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=269&mo delid=16186 , it shows that the camera is "Full HD" and "30p Progressive." So, why is FCP defaulting the Sequence Settings to 1080i? Is this default setting what I should be using?
Also, and perhaps more importantly, if I go into Motion 3 to create things to add to FCP projects that use the footage from my HF10, what settings should I choose in Motion 3's Select Project Preset window?
Thanks!

QoS Settings

Team - I'm looking to ensure I get the highest quality on my Skype calls. I have an ASUS RT-AC66U router which is BLAZING fast but want to I get the best quality on my Skype calls. Does anybody have any info about what protocols I need to prioritize or info on how to ensure I maximize the QoS settings on my router to get top speeds for Skype? Thanks, Jason

my 2 cents: 1. I believe Skype packets don't want to be identified, because this can lead to some sort of sabotage by telecoms / admins. 2. People don't know how to do QOS in Skype (because Skype doesn't want they do this), but the community mecanism forces them to always answer (to get more kudos), so they will reply with unhelpful answers like: "QOS is useless", "try to do with DMZ", but this is not what you are looking for. 3. In technology everything is possible, but sometimes only with hard efforts. I don't know how to do this in Skype in a easy way, but maybe you can force Skype to use a specific IP (by using the proxy setting or using Skype in a virtual machine) and configure your router to do QOS with this specific IP.

Defining best Qos settings for SRW248G4

I would like to thank anyone taking the time to help me out in advance.
I currently have ports e22 and e32 set with a Cos of 7 and a que of 4 because they are the ports used by my phone system and my router which are used for the Voip tunnel between our two locations.
Is this the correct settings? Should I do anything else as well?
Thanks... Kevin

Cos classifies traffic of ports into separate classes.
Those classes are assigned to queues with the queue with higher number having higher "priority" then the lower ones.
Thus, it is impossible to tell whether your settings are "correct" or not.
1. It depends very much on the objective of your QoS settings. I guess you want to prioritize VoIP.
2. It depends on all the other QoS settings as well. Prioritization is a relative thing to other traffic. Without knowing the QoS settings of all other ports it is thus impossible to make an accurate statement.

I observed different thing on SUP 2T. I saw packets matching ACL statement 'permit udp any any' but when I took off this line, ACL was not showing packets matching.

How Do I Change My Sequence Settings to Match My Clip

Hello -
I shot some footage in SD with a frame size of 16:9. When I dragged a clip into my first sequence, FCP asked 'if I wanted the Sequence to assume the properties of the clip?' I hit 'yes' which changed the sequence to match my clip. However, when I created a new sequence(in the same project) and dragged a clip into it, FCP did not prompt me with the option to change the sequence settings. Now, I have a 4:3 sequence with a letterbox 16:9 clip. Any suggestions on how to fix this? Thanks for your help!
