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.

  • Understanding QoS settings

    After going through the config on one of our switches I noticed some QoS settings that I have no idea what they mean and was wondering if someone could help me understand what these settings mean. Here is the config I found plus the config on one of the ports:

    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.

  • 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 was given an iphone 4s by my sister as she got a new one, now i want to clear it so that i can set it up with my own details, if i erase all content and settings will this affect anything on her new iphone as it is synced to the same gmail account

    her contacts are connected directly with the Google Server so as long as they are saved to her Gmail account she should be 100% fine.. the only contacts she may lose are the ones that she added directly onto the phone and did not sync to her Gmail account.. so you should just double check with her on that

  • 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.

    Well, this is a recurring issue for many users...a small percentage of users but still a bug.  Report the issue here to Apple:  www.apple.com/feedback
    iOS7.0.3 will be released next week, which as of now, I know is primarily for an iMessage but hopefully it will clear up some of these email issues some are also having.

    Hey shahbazfromgbr,
    Thanks for the question, and welcome to Apple Support Communities.
    I understand you are having issues with sound output on your iPhone 4S. For troubleshooting steps, the following article provides the best information:
    iPhone: Can't hear through the receiver or speakers
    http://support.apple.com/kb/TS1630
    1. Verify that there is nothing plugged in to the headset jack, including headsets, headphones, or adapters.
    2. Make sure the Ring/Silent switch is not switched to silent.
    3. While on the Home screen, adjust the volume buttons. If you see the icon below, indicating that headphones are attached, there may be debris or an object lodged in the headset jack:
    4. Check the headset jack. If there is an object lodged in the headset jack that is not easily removed, have the iPhone serviced to remove object.
    5. For Original iPhone: If there is light debris, such as lint, in the headset jack, try connecting a pair of headphones to the headset jack and then remove the headphones. Repeat this several times to remove the debris.
    6. If you have installed a protective film on the display, either ensure that the receiver is not covered or remove the film completely.
    7. Check the receiver mesh (which is on the top front of the device, above the display). If it appears blocked, use a clean, small, dry, soft-bristled brush to carefully and gently brush away any debris.
    8. If you have paired with a Bluetooth headset that is nearby, either use the headset or turn Bluetooth off (choose Settings > General > Bluetooth).
    9. Restart the iPhone.
    10. If restarting the iPhone doesn't resolve the issue, try restoring the device.
    11. If the issue persists, go to the Service Answer Center - iPhone for information on service.
    Thanks,
    Matt M.

    My Ipod 4th gen with 6.0.1 ios won't play on my sony docking station.  I have allready reset all my settings.  Is there anything else I can do?

    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup. See:       
    iOS: How to back up           
    - Restore to factory settings/new iOS device.
    Does Sony say it will work with a 4G iPod with iOS 6.0.1? Sometimes an iOS update will break compatibility.
    Do you have the latest firmware on the dock? Go to Sony's website and check.

  • 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?

    Hi Friend,
    Which kind of account are you using?
    If you are using a business account (for example [email protected]) you must set POP account info properly, filling all the blank fields (name, email address, description, password, Host Name, user's name, SMTP). Just one field blanked causes error in sending/receiving.
    If you are using a default account (iCloud, Yahoo!, Hotmail...), fill all the blank fields (Name, Email account, Password, Description) and sign in.
    If not works, delete the account and sign in again
    Hope it will be helpful
