Question about QoS in Wireless

Hi,
I've spent some time reading about QoS in Wireless but can't get my head around a few things. QoS is a confusing subject.
In the WLANs -> Edit WLAN you can set a QoS profile, from Bronze to Platinum, as shown in the picture.
1) Does this level tag ALL traffic on the WLAN to Platinum if the client does not tag the traffic itself to other values? In other words, is Platinum the default level?
2) I've read that this setting is the maximum level of QoS permitted on the WLAN, in that case I should set it to Platinum if I have VOIP traffic and regular DATA traffic on the same WLAN? For instance Lync/Skype?
3) How does this relate to AVC profiles? I've prioritized certain apps (lync gets DSCP 46) and down-prioritized others (youtube gets DSCP 10), will the values I've defined be tagged with Platinum since I set the WLAN QoS profile to Platinum? Or will they retain their original value as I defined in AVC Profiles.
4) Which clients are not WMM compatible? It seems almost all regular computers support WMM.
Can someone confirm the following QoS is true for the wired infrastructure: WLC ports are mls qos trust cos and AP ports are mls qos trust dscp. But what about trunks between switches and the uplink to your ISP? trust dscp?
Will be thankful if someone can shed some light on this.

NO
2) I've read that this setting is the maximum level of QoS permitted on the WLAN, in that case I should set it to Platinum if I have VOIP traffic and regular DATA traffic on the same WLAN? For instance Lync/Skype?
Yes, this is max level allowed. you should tag to platinum if you have VOIP clients. i dont think skype sends data with priority voice. not sure about lync.
3) How does this relate to AVC profiles? I've prioritized certain apps (lync gets DSCP 46) and down-prioritized others (youtube gets DSCP 10), will the values I've defined be tagged with Platinum since I set the WLAN QoS profile to Platinum? Or will they retain their original value as I defined in AVC Profiles.
wlan setting takes precedence over AVC if i recall correctly
4) Which clients are not WMM compatible? It seems almost all regular computers support WMM.
yes all modern clients are WMM compatible. you need WMM compatibility for 11n/ 11ac rates
Can someone confirm the following QoS is true for the wired infrastructure: WLC ports are mls qos trust cos and AP ports are mls qos trust dscp. But what about trunks between switches and the uplink to your ISP? trust dscp?
trunks are usually trust cos and access ports are usually trust dscp. you need to make sure end to end qos is configured properly.

Feq questions about QOS

I have few questions about QOS
1) Can qos policy only be applied at incoming frame/packets or it can also be applied at outgoing frames?
2)Is it correct that qos policy for incoming frames , will decide the queue the frames be at placed ingress port?
3) Is it correct that qos policy for outgoing frames,decides the queue the frames be placed at egress port?
4) Is it possible to trust the Cos/dscp in frame/packet and have qos policy for outgoing frames ?
5) Scenario:
When f0/1 is in trunk mode:
sw1(config)# int f0/1
sw1(cofig-if)mls qos trust dscp
when switch receives the frame,will it drive the cos value from dscp-cos map and place the frame in appropiate queue?
When f0/1 is not access mode:
When a switch receives the frame , Would switch drive the cos value from DScp-cos map even though the port is in access mode and place the frame in appropiate queue at ingress port?
thanks a lot!

Check out the SRND for QoS, it will answer of the questions you've posted here.

Question about QOS

We have a multi site network that is connected together via a managed ATM network The ATM network is our "core" network and we have no control over it. THe question I have is about how QoS would work over the core. We have QoS configured on all of our "Edge" switches at each site. I would figure that traffic going through the core would not adhere to our QoS policy but once the traffic gets to another site I would assume it would start using the QoS qualities that were assigned to the packet. Is this right?

Yes, you are correct.

Not so trivial question about extending a wireless network

Hello,
I've always had Wi-Fi signal strength issues in my house. Two days ago my Linksys router died and I got the new AirPort Extreme. Things got a bit better signal wise. Feature wise things got a whole lot better! Which got me thinking about the next step.
The two farthest corners of my hose are wired with CAT5E, and I have a gigabit router. My AirPort Extreme is on one of these corners, meaning I have a weak signal on the other corner. My question is, can I add another AirPort Extreme to the other corner, hook it on the wired LAN and have it extend my wireless network? I don't want to see 2 different networks. I want to see just my wireless network and have a strong signal everywhere. Can this be done?

Actually a Linux server is my internet connection (has two NICs). All the computers in my house plug into a Gigabit hub. The AirPort express is configured as "Share a public IP address", instead of "Bridge Mode", because I want to be able to use the "Guest Network" feature (so cool!). Yes I have two DHCP/NAT servers, but they don't interfere with each other, as they are on separate networks. My main network is 192.168.1, my AirPort network is 192.168.2, and my Guest Network is 10.0.42.
I will try both your suggestions and report back. It would be perfect if I could just plug the second AirPort to the Gigabit hub, but I don't mind chaining it to the first AirPort, if that's what it takes.
This is turning out to be a really fun project and I might finally fix the wireless signal in my house after all these years
Thanks!
Erasmo.

Show policy-map interface | Question about QOS show command output

I hope this is the correct place for this question. If not, please let me know.
When I issue the show policy-map interface command (in this case on a 3845) there is some output I don't understand. I have included some output below and formatted the lines I am confused about as "computer code" which show up as red on my screen. A list of the individual lines i'm confused about is below, followed by those liens in the context of the show policy-map command's output.
Any help with this will be greatly appreciated. Thanks in advance.

Question about Linksys G Wireless Router and i cant connect my iPod Touch and PSP to it.?

I just got a new Wireless router and it works fine.The model number is WRT54G2. The internet is working and I can go on my xbox live and things like that. The only problem is that my iPod touch and things and my PSP can detect the connection but are unable to join it. Why is this. It was working fine on my previous router. Is there some security thing I have to take off? How do i do this? Thanks in advance

I tried this and it went to a redish gray page that said "401 Unauthorized Authorization required" Help please?
It means you entered the wrong password or username, try some other passwords you might have used if the default admin doesn't work.

Question about Load Balancing Wireless connections using WLC- F5- ISE

Hi all,
Can anyone give me some orientation how the radius auth process/handshake between the WLC and ISE changes once the F5 is installed in the middle in order to perform load balancing?
We can do some kind of load balancing by configuring different radius servers on each WLC for which, I must configure the same shared secret in the WLC and ISE so the radius request/accept could be processed.
Now that we have the F5 in the middle, do I need to create/configure the same shared secret in the F5 so radius transactions can be processed by this device?. Based on the following link, I must configure the F5 in the ISE like another NAD device (similar to the WLC) but I do not know if this additional configuration in the ISE includes the Auth parameter to be added in the ISE NAD (F5) configuration.

Questions about Digital Wireless Headphones CB2

Hi everyone,
I have a question about the [url="http://nl.europe.creative.com/products/product.asp?category=437&subcategory=438&product=6 44" target=_self>Digital Wireless Headphones CB2530[/url] I've never seen it in a shop here in Holland, so I thought I'll pose my questions here.
I'm interested in buying one for my Creative Zen Xtra MP3 player.
My questions are:
- if it's possible to connect it to the player?
- can I use it while traveling (can i hear something if I put the player in my bag)?
- is it a good idea to buy this headphone? (i already have a great headphone by Philips, but am looking for wireless)
I also have a question concerning a remote control. Is there one for the Creative Zen Xtra?
I hope so...
Thanks in advance.
Greetings,
Eline

Eline,
Yes, you can connect the wireless headphone to the player. Infact you can connect it to any stereo devices with the audio transmitter as long it's using a 3.5mm minijack. It shouldn't be a problem for the audio even if the player is inside the bag. It works about the same way as a mobilephone to a Bluetooth headset. Unfortunately, the Zen Xtra player does not support remote control feature.

Looking to buy, but questions about wireless

I am hoping to buy a macbook very soon, but I have some questions about the wireless. I have heard that you can only use an apple router for the wireless, but already have a regular Linksys router. Is this going to be a problem?

I have been using a Linksys with Macs for two years and never had a problem.

A lot of questions about my MacBook Air

I am really new to re-using Apple computers.The last time I used an Apple computer was back in 1987 when the school and my family had Apple IIGS computers. I have been using PC's which reqiure Microsoft. I a lot of have questions (10 questions) about my MacBook Air and I hope you good people can and will help me.
Product: MacBook Air
Operating System: Mac OS X Version 10.7.4
1) I Downloaded MacKeeper because I was fooled. I had a bad feeling just before I Downloaded it and I should have listened to my heart. However, I didn't buy it or fully Install it. It was like a test run and then they wanted me to pay almost $100 for it. Thankfully, I didn't because I read it is Malware. I spoke with an Apple Tech at Apple Care and he helped me get rid of it (or so we think). I don't see it anymore on my computer. I read it can slow down your computer. How can you tell if it's really off of the computer?
2) When I open "Finder" and I see that there are people Sharing my computer with me. I went into AirDrop and it reads, "Other people can see your Mac as (my name) MacBook Air when their computer is nearby." I bought a HotSpot and while it's turned on and I selected it as my WI-FI connection I thought it would get rid of these people, protect what I type, me, my items, computer, etc. But it didn't.
I didn't know that I have to buy a exteral CD and/or DVD Player in order to connect to the brand new Modem and Router in one by NetGear. I am so used to PCs and the CD/DVD Players being built inside.
The people at Apple Store told me that there is an internal modem inside, but I don't know how to find it and what to do then. Should I use a Firewall?, An AntiVirus, AntiMalware, AntiSpyware, etc. Apple Care tech told me I don't need to get an AntiVirus.
3) Is there a new kind of Wireless Modem and Router that doesn't require a CD-ROM?
4) When I travel or fly and I am not close to home I was told by Best Buy and Sprint that I had to buy a mobile HotSpot to use the computer (WI-FI) safely. As I typed, I have one. But it's pretty expensive and only gives me 1 hour and 15 minutes per day to Stream. What can I do to use this computer safely Online when I am out of range from a Modem and Router? What do people do when they travel on airplanes?
5) This compter won't let me use "Raid." I think you have to have a newer version. I hard about Raid on the radio from Leo (can't recall his last name) who's a Tech expert.
6) Should I buy a ZipDrive? Apple Store Tech told me that I didn't need a ZipDrive. I just remember the episode of HBO's "Sex and The City" when Carrie looses everything because her copy crashed. Now, of course, I know that's a fictional show, but with PC's and Microsoft I have lost everything when it crashed, frooze up, etc. I know there's iClouds. I heard about Carbonite, but I have read the Pros and Cons about it. Mostly they are Cons about it. I just don't want to do anything wrong and mess up this computer.
7) Should I buy a new Printer/Copier/Scanner because mine is an HP. It's not new, but it works. I even have a CD-ROM for Macs. What about the new product called, "Neat"?
8) Is there a special product that I should buy to do Online Banking and/or other important stuff?
9) I saw and read about iWork in the Apps Store and it sounds cool. I still have alot of friends and colleagues who still use Microsoft. Is iWork good to use? Should I Download it from the Apple Apps Store or can a buy it at Apple? Is there another Word Processing Program that is great and user friendly and will work with Macs and PCs?
10) Should I Update the OS with OS X Mountian Lion Pro from the Apple Apps Store or buy it at Apple Store?
In advance, I wish to thank you in this Apple Support Communites for your help. Have a safe and happy holiday weekend!

1) Here are instructions for removing MacKeeper. Since it mostly consists of manually looking for folders and specific files, if you follow the instructions you either fail to find what you are told to find (because your AppleCare guide gave you complete instructions which you followed) or you'll find some additional files that need to be replaced.
2 & 3) I assume you are looking at the sidebar of a Finder window and seeing Shared and computers under it. Those are computers that you can potentionally share. To do so you'd need an account on their computer and a password. They are not sharing your computer.
AirDrop allows you to create an adhoc network for filesharing and it only functions when you have selected the AirDop item in the SideBar. Actually doing that merely announces to computers in the same network node that your computer is available for a file to be sent to. Even then you have to explicitly allow the file to be downloaded to your computer. Similarly you'd be able to see other computers with AirDrop selected and be able to send them a file - which they'd have to accept.
The only reason your NetGear Router comes with a CD is to install and run their 'easy' step by step configuration program. It can also be done manually with a browser. Read the manual to find the IP address you must enter to access the router's configuration menu. Apple's WiFi routers don't require a CD to install the software because the configuration software is already on your computer.
I do have my firewall turned on. AntiVirus software isn't a bad idea - I use Sophos having tested it for a review for our local User Group and I found I liked it better than ClamAVx which is what I'd been using before. Both are free.
4) I think you were scammed by Sprint and BestBuy. I use hotel, coffee shop, and restaurant WiFi spots and have for years. However, because they can be unsecured, I do not shop online or bank when I'm using them. I also use 1Password and don't reuse passwords so even if a sniffer should grab an account and password that's all it would get - one account.
5) Raid doesn't really make sense with a MacBook Air - a RAID involves 2 or more disks being used as if they were one.
6) Zip drive? No. External hard drive - yes. It isn't a question of if a computer's hard drive will malfunction, it is when. OWC has a nice selection of external drives and the Mac has a built in backup system called TimeMachine. Due to the way TimeMachine works, I've found that your TimeMachine drive should be at least twice as large - and preferably 3-4 times as large as the data you are backing up.
7) if your printer works and it has Mountain Lion drivers, why replace it?
8) Online banking is done with a browser - Use Safari or FireFox
9) If trading files with Windows users is important Mac: Office is your best bet. If not, iWork, Mac:Office, or LibreOffice are all good possibilities.
10) you can only buy Mt Lion via the App Store.

Questions about 3702i and WSM (WSSI)

I have several questions about the 3702i AP and the WSM that do not seem to be answered in the data sheets/documentation.
Any insight would be appreciated.
1. Is the WSM officially supported on the 3702 AP? The documentation seems to conflict on this.
For example, at the top of the WSM data sheet: "Flexible add-on third radio module for the Cisco Aironet 3600i or Cisco Aironet 3600e Series Access Points". Then later on in the page graphic shows the 3700 series radios too. I have found multiple pages that have similar conflicting information.
2. Can the WSM be used WITHOUT MSE and Cisco Prime? If so, are there any limitations?
3. How does the licensing work? Where is the license installed -- WLC, MSE, Prime? Do ANY of the features work without the license?
3a. How do you order the license? The SKU listed on the data sheet (L-WIPS-MM-1AP) is not a valid part number in CCW.
4. Is it possible to do sniffing with a WSM? (the idea being not having to dedicate an AP to sniffing, or taking down a client-serving AP to sniff)
Thank you.

Ok, so you are talking about off-channel scanning, which is actually a very short duration 50ms, that the AP is actually off-channel to scan.
http://mrncciew.com/2013/03/16/configuring-rrm/
Are you thinking of this bullet point?
Access points with wireless security module: The Cisco Aironet® Access Point Module for Wireless Security aggressively scans all channels without affecting the data-serving radios in the 2.4- and 5-GHz bands.
To me, that's just saying that the WSM is scanning and not interferring with the AP's normal radios.
HTH,
Steve

Some questions about a Time Capsule

Hi!!
I just have a few questions about a Time Capsule, but first let me explain the backgroud to my questions.
I live in a 2 floor house(including a basement) and my bedroom is downstairs. My parents currently have a desktop PC connected to our wireless router and our printer. Me and my step-father both have 13 inch MacBook Pros, and he uses the Mac like a basic computer, so the equipment connected to our PC is good for him. I, on the other hand, use my Mac, iPad and iPhone to their fullest potential. I am a SUPER MEGA NERD when it comes to computers, so I plan on making my bedroom an amazing office at the same time. So I want an AirPrint Enabled printer in my bedroom (Under 100$$) along with a Time Capsule to back up my information, because everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
If you don't understand what I'm trying to ask (Even though I feel like it's self-explanatory)
ONE question about the PRINTER: Do any of you have any recommendations for an AirPrint Enabled printer under 100$? Even under-150$ would be okay.
THANKS FOR ANY HELP!!!!

everyday I look around in the backdoor of my Mac alot, and if I jack anything up (And I cant handle the problem) I would like to restore my Mac to a previous version. So here are my questions:
Don't just depend on TM.. use a disk image type utility.. either one of the Mac tools, SuperDuper, CCC, Chronosync or even a linux boot cd (if you have a cd/dvd drive still or via usb can boot) a great tool is Clonezilla.. it will do basically any computer, Mac, Linux, Windows.. and since it boots into its own OS can restore a computer in a flash. Then you can add the incremental changes from TM.
1) My bedroom is right underneath our router, so i get GREAT Wi-Fi in my room. If I get a Time Capsule, can I use it in my room to extend my Wi-Fi, and how would that work? Will it extend my wifi under the same name, because I would like my own Wi-Fi (Titled to what I want with my own password)
Actually I am surprised you get good wireless as usually directly above or below a router is often the worst spot. Time Capsule cannot extend the wireless of any other router than Apple.. it is a special system and only Apple can join the club. It has bad effect though, if you set the TC to extend wireless it turns off ethernet ports.. which is hugely dumb.
The best arrangement is ethernet to the upstairs.. or EOP adapters. If not then a wireless router that matches the existing unit will generally be better than mixing apple and non-apple.
2) If I have to create a NEW Wi-Fi network, how would I do that?
3) Would I need to connect my new printer directly to my ROUTER, or could I connect it to the TIME CAPSULE?
You create a new wireless network by selecting manually the wireless channel and use different wireless name, ssid and security. There are 3 available channels on 2.4ghz.. your existing router will use one or two.. depending on if the setting is 20mhz or 40mhz.. so you need to manually set everything and not use auto.
TC is slow on 2.4ghz cf 5ghz and there are many more channels at 5ghz but not everything can use it.. iphone for instance is 2.4ghz only . whereas ipad can use 5ghz.. most full computers now can use 5ghz.
Buy a wireless network printer. Or alternatively an ethernet network would be also ok but now are more expensive than wireless ones. Network printers are not much more than straight USB and work much better.
I do not use airprint so have nothing to offer.. find the best HP model in your budget.. but others may have had more experience.. I use ethernet connected b/w laser business type HP.. they work great.. but airprint is too recent an innovation for me.

Two Questions about Airport Express

All, I am a recent convert to using a Mac so bear with me.
I have two questions about the Airport Express.
Question if I buy one in the USA, I will visiting this week on holiday,can I use it the UK with a UK adaptor/apple plug?
Can the Express be used with my current wireless network, using a Netgear DG834G V4, I have read lots in the forums about putting a $ sign in front of the WPA password?
Any help and advice gratefully received.

Hello andixbox. Welcome to the Apple Discussions!

Yes, but at least two things to consider:
o The US version of the 802.11n AirPort Express Base Station (AXn) only supports radio channels 1-11 in the 802.11g radio mode. Channels 12-14, used in other countries outside the US will not be available.
o The AXn supports both the 2.4 and 5 GHz radio bands for 802.11n. The 5 GHz band is restricted in certain countries (like the UK) so operating in this mode may get you unwanted attention.
That should be okay then because the Netgear broadcasts on channels 1-11. I hadn't appreciated the 5 Ghz band, but having checked both US and UK Apple sites the techspecs both mention 2.4 Ghz and 5 Ghz.
Can the Express be used with my current wireless network, using a Netgear DG834G V4, I have read lots in the forums about putting a $ sign in front of the WPA password?
If your intent is to have the AXn join the Netgear as a wireless client, then yes it should work. The "$" requirement was for WEP. This shouldn't be necessary for WPA or WPA2.
I intended to use the AXn as an range extender, but you mention wireless client, is that something different?

Questions about mac mini iTunes server, streaming to macbook pro, ipads, etc.

I'm thinking about getting a mac mini to work with my NAS as a iTunes server. I have a bunch of questions about this. I will have two iPhones, a few iPads, and a laptop that will be accessing the files. I have iTunes match. This is basically to keep an always on computer for hosting the music/movies. My questions are as follows . . .
#1 Are there any good, comprehensive guides to show you how to do this?
#2 Can the movies be accessed when not at home on the shared network?
#3 Can the iPads or the macbook pro download the shared movies to be stored locally?
#4 Back to #3, how will it work on my macbook pro with listening to music (I have iTunes match)? Say i go to library and I break out my macbook pro and I don't have internet. What happens if I download music while at home onto my macbook pro to listen to it when I go to the library? Will i start a new library on my macbook pro? How will that mesh with the home server when I come back.
#5 Is there a way to mirror files or folders? So something that I have on my macbook pro will also mirror on the home server.
Thanks for your help on this. I'll post any follow up questions.

1. I want to replace the Optical drive with a 2TB SATA. can I use this 2.5 inch?
I do not know if it is the same model number, but this one will work in your MBP:

2. I want to replace the HD with a 128GB SSD 840. When I replace these drives, will my OS still be in tact? I have never done this job before.
No. You will have to format the drives in Disk Utility>Erase to Mac OS Extended (Journaled) and then install the OSX by using the original install disks.
3.) I want to replace the ram sticks to max capacity. This is 2 2GB sticks, Correct?
No. An early 17" 2008 MBP will accept 6GB RAM with the following specifications: 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM. The best sources of Mac compatible RAM are OWC and Crucial.
4.) Most difficult...
I want to extend the monitor wirelessly to a projector. I thought about using Apple TV and Airplay. However, support for airplay is for MacBooks 2011 and newer. I thought of using a PS3 and the media server, but I think this brings on a format compatibility issue. (my library is so large I could not afford to convert all my movies to MP4.) So, how would you recommend I put my extended monitor with VLC player onto a projector?
Could I possibly connect the MBP to a Mac Mini as an extension? would this work natively? I would rather use a VGA cord than F with 3rd party app BS.
Cannot help you there.
5..) I want to Bypass iTunes this time around. I would prefer to use Finder and VLC to manage all of my music. I mostly play all my music on shuffle, so, could I create a playlist on VLC with all of my music and play it randomly? (im sure this is possible but i'd like to organize all my plans with confirmation.)
You are not obligated to use iTunes.
6.) Can i upgrade the keyboard to backlit? i've read that this is possible.
All MBPs have back lighted keyboards. Your either needs a NVRAM reset or a repair.
Ciao.
