Disable data rate to a specific AP only?

Hello everyone, Im using Cisco 5508 with 7.0.220.0 code and I just wanted to know if its possible to disable some data rates to a specific group of APs and not affect the rest of the APs
Another question is about almost the same thing but related to WLAN Radio Policy. If I enable a specific WLAN to use radio policy 802.11g-only, all the clients using this WLAN can only associate to 802.11g data rates??? are there any other things to consider on about this policy?.
thanks in advance for your time and help!!!!

Rasika is right on... you need to upgrade if you want to use RF Profiles...
Another question is about almost the same thing but related to WLAN Radio Policy. If I enable a specific WLAN to use radio policy 802.11g-only, all the clients using this WLAN can only associate to 802.11g data rates???
> Clients can only connect on the 2.4ghz either 802.11b g or n
are there any other things to consider on about this policy?
> Setting the policies on the WLAN just defines what you want to be able to associate to that WLAN.  For example, wireless ip phones you might set it to 5ghz only, so phones have to be able to connect using only the 5ghz.  If there were any 2.4ghz device only trying to access that wlan, they wouldn't be able to associate.  Another example is like guest ssid... I always only allow then on the 2.4ghz, not on the 5ghz.
Thanks,

  • Convert a sales value to the reference currency with the exchange rate of a specific date

    Hi Friends,
    I Have 2 Dimensions: Time and Currency
    I also have to fact tables, exchange rate and sales
    Both fact tables have references to Time and Currency Dimension.
    The user want to select using excel the sales in the local currency and the correspondent conversion in the reference currency (the reference currency is fixed) in the selected date.
    To obtain the desired exchange date I need a date and a currency. The user select in excel a specific date but the currency must be the current currency in the sales table. I achived something like this in the query editor:
    with
    MEMBER [Measures].[Current Rate To Euro] AS (
    ([ISO Currencies].[ISO Curr Code].CurrentMember, [Time].[Date Id].CurrentMember, [Measures].[Exchange Rate To Euro]))
    MEMBER [Measures].[Net Sales Euro] AS (
    [Measures].[OOH Net Sales Dom Snapshot]/[Measures].[Current Rate To Euro]
    SET NE_measures as {[measures].[Net Sales Value Domestic], [Measures].[Exchange Rate To Euro]}
    member m_NonEmptyCheck as
    Generate
    NE_measures
    ,{Iif([Measures].CurrentMember, [Measures].CurrentMember, NULL)}
    ).Count = NE_measures.Count
    ,NON_EMPTY_BEHAVIOR =

    ,m_NonEmptyCheck
    ) on 1

    But I don't know how to translate the last select in a calculated measures in order to let the customer only to select this measures in the values area and the time in the filters.
    Any comment would be appreciated
    Kind Regards

    Was not so difficult as I thought, however, it took me several hours to understand how could it work:
    with
    MEMBER [Measures].[Current Rate To Euro] AS (
    ([ISO Currencies].[ISO Curr Code].CurrentMember,[Time].[Date Id].CurrentMember, [Measures].[Exchange Rate To Euro]))
    MEMBER [Measures].[Net Sales Euro] AS (

    *{[Customers].[PDU Description].[PDU Description]} on 1 -- An attribute of the customer hier.
    from [DM ISR DEV]
    I think all of my confusions come from my Sql background. A calculated member is a member that is resolved by calculating an MDX expression to return a value, not a set, for this reason the key to solve my problem was the SUM function.

    Verizon is using the Elipsis tablets to steal data from their customers.  The only way to stop data from registering as cellular data is to pull the SIM card.  This occurs with wifi enabled and cellular,dara disabled.  If,you take your tablet to a Verizonstore they will upgrade your data plan to cover the overage and credit the upgrade.  You will then have to remember to downgrade your plan or continue to pay for more data.  Verizon, how would you feel if I walked into one of your stores and started filling my pockets with merchandise?  If cought can I just give the product back and say "oops, sorry"

    Today, my FCC complaint hit the same person working on the BBB complaint.  Jimmie has been very nice and seems willing to work with this problem.  We have been able to come to an agreement.  I paid the purchase price for the phone and he returned my upgrade and unlimited data plan.  This is what would have occurred if Verizon had given me correct information to begin with.  I am happy with this result.  He also brought quite a few instances concerning the handling of my transfer and upgrade that did not follow proper procedure.  I am also confident that I would not have resolved this without complaining to BBB and or FCC.  Verizon had no interest in solving the problem nor did they show any propensity to keeping a 20 year client.  Even though this last CSR was very polite and helpful, his sole job is to respond to formal Federal and State complaints.  He is required by law to address every complaint and report the reporting agency the agreed upon results - good or bad.  Again, I suggest - If you are not getting the proper customer service, complain to someone outside of Verizon.  Jimmie had not received any complaints registered with Verizon directly and I still have not had any contact with any other management representative that I was told would call.

  • PGC DATA RATE CS5

    Hi,
    I have a issue when trying to burn a dvd with encore cs5, I get a error message before the burning process.
    PGC "sequence 1" has an error at 01:12:43:03.
    The data rate of this file is to high for DVD. You must replace the file of a lower data rate.
    This is my work flow
    Footage is XDCAM EX 1440x1080/50i 25fps pal widescreen.
    in premiere I use the direct export setting to Mpeg-2 dvd. settings as in attached image. Once exported, I close premiere, open encore, import the video and audio file and place on the timeline, make chapters ect. press build, and before burn. ERROR.

    There were what I called "persistent" pgc errors in CS3 - meaning that even with good workflow, some users got pgc errors that could not be solved but, in most instances, could be worked around.
    Such errors have not occurred in CS4 or CS5.  A pgc error in CS4 or CS5 is usually more specific (the data rate message for example).
    FYI, I got the pgc errors in CS3.  I still have not upgraded my PC, but finally loaded CS4 to test an issue.  No pgc error in a project that had one in CS3.
    So I agree you should be looking for pgc errors only in CS4 or CS5, or that include the data rate message.
    But Jon nailed this I suspect!

  • WLC Data Rates behaviour

    Hello everyone!
    I have some questions about the data rates configuration in WLC. I've been reading Cisco documentation and this forum, but as I've seen some contradictory information I would like you to clarify me some points.
    I want to disable 802.11b clients, so for that I'm going to disable 1, 2, 5.5 and 11Mbps data rates (other option could be set these as supported only). Then, I have to assign at least one of the other data rates as mandatory...
    I could think in one of these three options
    Option 1: all 802.11g data rates as mandatory. In this case, as far as I understand:
    Broadcast are sent to the lowest data rate
    Multicast are sent to the highest data rate (but if a client is connected to other data rate than the highest, then multicast frames are sent to this data rate supported by the client, is that right??). Basically, you cannot be sure at which data rate multicast frames are sent as it can change depending on the clients.
    Clients can connect as soon as they support one of the mandatory data rate
    Option 2: one 802.11g data rate as mandatory. This would define better the cell limits.
    Broadcast and multicast are sent at the same data rate
    Clients can connect if they support the mandatory data rate
    Option 3: set two data rates as mandatory (or the OFDM required data rates: 6,12, 24Mbps), and the others as supported
    Broadcast are sent at the lowest data rate
    Multicast are sent at the highest data rate (shifting back to the lowest if a customer cannot connect to this data rate)
    Clients can connect if they support at least one of the mandatory data rates.
    Am I right with this assumptions? I have read some other different behaviors, like broadcast and multicast are sent at the same common data rate...
    I hope I have explained myself...
    Thank you very much for your support.
    Carolina

    Hello,
    thank you Scott and George!
    I read the post, and it is ok, and I finally have found some information in Cisco's website:
    http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_01011.html#ID2482
    "Access points running recent Cisco IOS versions transmit multicast frames at the highest configured basic rate and management frames at the lowest basic mandatory rates, can cause reliability problems. Access points running LWAPP or autonomous Cisco IOS should transmit multicast and management frames at the lowest configured basic rate. Such behavior is necessary to provide good coverage at the cell's edge, especially for unacknowledged multicast transmissions where multicast wireless transmissions might fail to be received. Because multicast frames are not retransmitted at the MAC layer, clients at the edge of the cell might fail to receive them successfully. If reliable reception is a goal, multicast frames should be transmitted at a low data rate. If support for high data rate multicast frames is required, it might be useful to shrink the cell size and disable all lower data rates.
    Depending on your requirements, you can take the following actions:
    If you need to transmit multicast data with the greatest reliability and if there is no need for great multicast bandwidth, then configure a single basic rate, that is low enough to reach the edges of the wireless cells.
    If you need to transmit multicast data at a certain data rate in order to achieve a certain throughput, you can configure that rate as the highest basic rate. You can also set a lower basic rate for coverage of nonmulticast clients."
    Based on your experience, does it have any sense to have configured all datarates as mandatory? This is the current configuration I have in our controllers but it wasn't done by me.
    Thanks.

  • Disabling Low Rates on a WLC

    I was wondering if disabling low rates could cause issues for clients in higher density areas. For example, if I have 9 meg as the minimum allowed rate, what is actually taken under consideration for that rate? If I have a significant number of clients connected to that AP, is that going to be taken under consideration by the controller when calcultating the minimal supported rate to all clients? Or does it only take under consideration the distance between the nearest AP and the client and the obstructions in between?

    Mandatory rate is what the client must be able to negotiate at. Supported rate are rates the WLC will allow the client to negotiate to. Disabling the lower data rates only affect old devices that might require 1 or 2 Mbps data rate. Distance from the AP is a factor as what the client and ap negotiate at. In a high density deployment for example, I have had 24mbps as mandatory and everything below 11 or 12 disabled and the rest supported. I might also add another mandatory rate if I'm using multicast. You need to know your RF to really decide what you can have a a mandatory and it supported.

  • Data Rates & Cell Size

    Hi all.
    A few days back i was going through an article on High Density Wireless Deployments , and came through an extract which disabling Lower Data Rates , helps to reduce cell size.
    How doe this work ? I mean are we exclusively allowing only those clients to associate by making the data rates disabled for slower clients ?
    But isnt cell size , controlled by the Transmit power of the antenna ?
    Or what we are looking here , is just reducing the cell size logically?
    Thanks ,
    Rahul.

    No problem.... Look at it this way.... back in the days with autonomous, you could roam from one ap and not roam to the next two while walking down the hallway.  So in high density, you want to have some sort of control on how many clients you want in a cell or on a particular AP.  People always asked.... why an i connected to an ap 20 feet away and not the one above me.  Well for one, the client chooses and also why would it roam is it is still connected at a rate that you are still supporting.  There are so many tweaking involved with high density, well at least I do a lot of tweaking, but its so I can control the cell size for AP's in a high density area compared to areas where I need to extend the cell size a bit more.  Data rates and TX power work hand in hand when determining this.

  • Quick Notation Question - Data Rates/Frame Rates/Interlacing

    Finally upgraded to a decent prosumer camera and I'm trying to decipher what the manual is telling me about the many different formats it shoots and and the associated options.  I keep seeing things like "There are two basic shooting modes: 720p and 1080i/p.", which I'm finding confusing.  In my understanding, the "p" in 720p means progressive video and the "i" in 1080i means interlaced.  So what do I make of 1080i/p?
    On top of this, my camera shoots in "native" mode, which drops duplicate frames used in "over 60" formats.  This will give me variations in the notation like:
    720/24pN
    720p Native 60 fps
    1080i/24p
    1080/24PN
    Can someone give me a quick primer about frame rate vs data rate and explain how to read these notations?  I'd appreciate it quite a bit.
    Thanks!

    There are so many cameras, capable of so many different formats that providing a manufacturer and model could be helpful in this discussion.
    Jim's answer is absolutely correct but I'm going to re-state for clarification.
    The i/p designation means you can chose to record as interlaced or progressive for a given resolution.
    It sounds like your camera is designed to "capture" images at 60 frames per second, selecting "native" mode means extra frames are deleted and only the desired frames, based on frame rate setting, are recorded to memory. The advantage of "native" @ 24fps is you save space on your memory card. The advantage of NOT using "native" mode is that all 60 frames per second are recorded, but the file metedata tells playback software to only show the frames needed for the specified frame rate (i.e. 24). Since all 60 frames per second are recorded, you use more memory but you also have the option of retrieving all the those frames, if you so desire, at a later time (i.e. for smoother slo-mo).
    To be honest I don't know what your spec of 1080i/24p means. If that is truly an option then I would guess it means it will record a 24p image but the metedata would indicate the file should playback at 30fps interlaced by adding the proper 3:2 pulldown. This would give you that "film" look in a broadcast compatible format.
    For the most part, you don't want use use any interlaced settings. Very few display devices still in use can properly display interlaced images. Interlacing is only required in some broadcast specifications.
    To answer the second part of your question;
    Frame rates are an indication of how many times the moving image is captured over a given period (per second). Higher frame rates means smoother, more "real life" motion. Data rates can generally be considered an indication of image or audio quality. Higher levels of compression result in lower data rates and (generally) lower quality. If squeezing more hours of footage on fewer memory cards is more important than getting the best image quality, choose a lower data rate. Higher frame rates (more images per second) inherently require a higher data rate to retain the same quality as fewer frames at a lower data rate.

  • Disable date picker

    How do I disable date picker item (specifically the date picker pop up). I am workingon Version 3.0
    Thanks and Regards,
    Kumar

    Hello Kumar,
    In that blog post I explained how you can disable the clickable datepicker image (that will show the popup), when you disable your datefield.
    As you can see in the comment, if you add a condition to make the date field read-only the icon is automatically removed, but if you disable the datefield during navigation on your screen (using javascript), that wasn't happening.
    And in the example I used jQuery (installing that is a prerequisite), to disable all icons of date fields that are disabled.
    A function for disabling the icon of a specific datefield should be something like:
    function disableIcon( pThis ){
      var i=this.id;  
      $('#'+i+'_IMG').click(function() 
      {return (!document.getElementById(i).disabled);}); 
    }And you can call that using : disableIcon('Pxyz_DATE');

  • Disabling data usage on Elipsis Tablet does not turn of Data Usage

    Yesterday purchased 3 tablets for my kids. First thing I did when I got home was add home wifi and disable data usage. Ridicoulous but this does not disable data usage. Tablet used 4gb of data before I realized what was going on, all the while connected to home Wifi, like the data connectio took precedence. This is a major flaw of this tablet. Called Customer Service, waiting for a mgr to call back. Unfortunatly waiting on hold for over 45min without getting to tech support but in the end the only way to turn off data apparently (or at least I found) was to put in Airplane mode. This is not right!
    Even support forum states this is the way to enable/disable data. I feel dooped!

        I'm sorry you waited so long trying to get through to Tech Support dm805. I know being able to disable Mobile Data is important to keep usage under control. As Ann154 mentioned, you are able to turn off Mobile Data in Settings. You can go to Settings> Data Usage> Select Mobile Data (at top right hand side), and it will turn off.  You can also go to Settings> More> Mobile Networks> Uncheck Data Enabled.
    I hope this helps.

  • I have a question about Data Rates.

    Hello All.
    This is a bit of a noob question I'm sure. I don't think I really understand Data Rates and how it applies to Motion... therefore I'm not even sure what kind of questions to ask. I've been reading up online and thought I would ask some questions here. Thanks to all in advance.
    I've never really worried about Data Rates until now. I am creating an Apple Motion piece with about 15 different video clips in it. And 1/2 of them have alpha channels.
    What exactly is Data Rate? Is it the rate in which video clip data is read (in bits/second) from the Disc and placed into my screen? In Motion- is the Data Rate for video only? What if the clip has audio? If a HDD is simply a plastic disc with a dye read by "1" laser... how come my computer can pull "2" files off the disc at the same time? Is that what data transfer is all about? Is that were RAM comes into play?
    I have crunched my clips as much as I can. They are short clips (10-15seconds each). I've compressed them with the Animation codec to preserve the Alpha channel and sized them proportionally smaller (320x240). This dropped their data rate significantly. I've also taken out any audio that was associated with them.
    Is data rate what is slowing my system down?
    The data rates are all under 2MBs. Some are as low as 230Kbs. They were MUCH higher. However, my animation still plays VERY slowly.
    I'm running a 3GigRam Powerbook Pro 2.33GHz.
    I store all my media on a 1TB GRaid Firewire 800 drive. However for portability I'm using a USB 2 smartdisk external drive. I think the speed is 5200rpm.
    I'm guessing this all plays into the speed at which motion can function.
    If I total my data rate transfer I get somewhere in the vicinity of 11MBs/second. Is that what motion needs for it to play smoothly a 11MBs/second data connection? USB 2.0 is like what 480Mbs/second. So there is no way it's going to play quickly. What if I played it from my hard drive? What is the data rate of my internal HDD?
    I guess my overall question is.
    #1. Is my thinking correct on all of these topics? Do my bits, bytes and megs make sense. Is my thought process correct?
    #2. Barring getting a new machine or buying new hardware. What can I do to speed up this workflow? Working with 15 different video clips is bogging Motion down and becoming frustrating to work with. Even if only 3-4 of the clips are up at a time it bogs things down. Especially if I throw on a glow effect or something.
    Any help is greatly appreciated.
    -Fraky

    Data rate DOES make a difference, but I'd say your real problem has more to do with the fact that you're working on a Powerbook. Motion's real time capabilities derive from the capability of the video card. Not the processor. Some cards do better than others, but laptops are not even recommended for running Motion.
    To improve your workflow on a laptop will be limited, but there are a few things that you can try.
    Make sure that thumbnails and previews are turned off.
    Make sure that you are operating in Draft Mode.
    Lower the display resolution to half, or quarter.
    Don't expect to be getting real time playback. Treat it more like After Effects.
    Compressing your clips into smaller Animations does help because it lowers the data rate, but you're still dealing with the animation codec which is a high data rate codec. Unfortunately, it sounds necessary in your case because you're dealing with alpha channels.
    The data rate comes into play with your setup trying to play through your USB drive. USB drives are never recommended for editing or Motion work. Their throughput is not consistent enough for video work. a small FW drive would be better, though your real problem as I said is the Powerbook.
    If you must work on the powerbook, then don't expect real-time playback. Instead, build your animation, step through it, and do RAM previews to view sections in real time.
    I hope this helps.

  • Need to know the sqluery to find the disabled date from OIM 9.1.0.1

    Hi Experts,
    Need very urgent inputs from you all for the preparation of our audit.
    We are using OIM9.1.0.1
    We need to know the sqlquery for finding the Disabled date in OIM given the user ids, as currently we are unable to get the exact data from Historical Reports Option in OIM.
    I need to give in this format:
    select usr_login, usr_disabled from schemaname.tablename where usr_login in
    ('aaa','bbb'..... etc)
    We have three attributes :USR_DISABLED_BY_PARENT,USR_DISABLED,USR_DEPROVISIONING_DATE,but none of them give the exact date,
    USR_DISABLED gives just a flag as 1 or 0.
    Also there are no other fields in the corresponding usr table.
    So how to fetch the exact Disabled date from OIM system when I input the user ids.
    Your immediate response is appreciated.
    Thanks
    SS

    In the entire thread many experts have given nice queries in different formats...
    The best approach would be to open up the SQL Developer, connect with the OIM Database and experiment with all sorts of SQL queries provided by all the experts..
    Learn some SQL techniques, like Inner Join etc...
    Then you yourself will be able to figure out what you need, in exactly which format, for which users and for whom you have to restrict
    Then not only this question, you would be able to solve dozens of similar such issues yourself...
    And trust me, nothing can match that...
    Just in case, you are not familiar with SQL Developer,

    The Disabled DATE will be the creation date of that entry in the UPA_FIELDS table when Users.Status changed to Disabled.
    SELECT USR.USR_LOGIN, UPA_FIELDS.CREATE_DATE

  • H.264 All-Intra Data Rates Significantly Higher

    Does the built-in H.264 codec encode I-frame only files differently? I am trying to determine the optimal GOP length for high bitrate exports. Image quality seems to degrade, even in the I-frames, when using key frame distances greater than one.
    After performing a series of tests to characterize the Adobe H.264 encoder, I discovered that exported files are significantly larger when key frame distance equals one frame (N=1). The average video data rate for a test file rendered with the Adobe H.264 encoder is as follows:
    N=1 : 2.17 bpp : 24I
    N=2 : 0.66 bpp : 12I + 12P
    N=3 : 0.59 bpp : 8I + 8B + 8P
    Note how the data rate drops 70% (from 2.17 to 0.66 bpp) even though 50% of the I-frames still exist when N=2. By comparison, here is the video data rate when exporting with QuickTime H.264:
    N=1 : 0.89 bpp : 24I
    N=2 : 0.70 bpp : 12I + 12P
    N=3 : 0.64 bpp : 8I + 16P
    The following chart shows data rates at key frame distances from 1-48 frames for Adobe H.264, QuickTime H.264 (via Adobe), QuickTime Pro, and Expression Encoder 4 Pro. Data rates are consistent among all encoders at GOP lengths greater than one. There is an anomoly with the Adobe H.264 codec compressing all-intra files.
    The observed behavior occurs in all profiles, which were tested at Levels 4.1, 4.2, 5.0, and 5.1:
    Image quality is better in the Adobe H.264 all-intraframe file, especially with respect to detail retention. The pictures below show sections of two consecutive frames magnified 400%. The file with N=2 is less accurate and contains noticeable blocking. Even the I-frames don't look as good in the files where N>1.
    The test file was a seventeen second Premiere Pro sequence consisting of H.264, MPEG-2, and AE files with effects applied. Exports were rendered from the Premiere Pro timeline and from a V210 uncompressed 4:2:2 intermediate file of the sequence. The following settings were used:
    Format: H.264
    Width: 1280
    Height: 720
    Frame Rate: 24 fps
    Field Order: Progressive
    Aspect: Square Pixels (1.0)
    TV Standard: NTSC
    Profile: Baseline, Main, and High
    Levels: 4.1, 4.2, 5.0, 5.1
    Render at Maximum Bit Depth: Enabled
    Bitrate Encoding: VBR, 2-Pass
    Target Bitrate: Maximized for each Profile/Level
    Maximum Bitrate: Maximized for each Profile/Level
    Key Frame Distance: 1, 2, 3, 4, 5, 6, 7, 8, 12, 24, 48
    Use Maximum Render Quality: Enabled
    Multiplexer: MP4
    Stream Capability: Standard
    Software:
    Adobe Media Encoder CS6 Creative Cloud v6.0.3.1 (64-bit)
    Premiere Pro CS6 Creative Cloud v6.0.3
    Windows 7 SP1
    QuickTime Pro for Windows v7.6.9 (1680.9)
    MediaInfo 0.7.62 (for GOP and data rate information)

    I think the short answer is yes,
    a h.264 encoder does I-frame only differently. I frames are complete expressions of a picture with no temporal compression information.
    P frames use _P_redictive information. IE information from prior frames.
    B frames use _B_i-directional predictive frame information.
    h.264 gets the majority of it's bit saving from use of B and P frames. When you do I-frame only you only get the block compression and none of the advantages of P and B frames. Thus the GOP N=1 doesn't get very good bit's per pixel.
    Having said all that I do find your comment...

    Note how the data rate drops 70% (from 2.17 to 0.66 bpp) even though 50% of the I-frames still exist when N=2. By comparison, here is the video data rate when exporting with QuickTime H.264:
    ... very interesting. Indeed, why is the datarate 70% less when it should at best be 50% for GOP N=2. 50% less should be the same I-frame information plus 0 bytes for the B frame between them. (GOP = I,B,I). Any more than that and it is throwing away bits from the I-frame. So, this seems to be to be a ratecontrol bug.

    "The GOP structure is often referred by two numbers, for example, M=3, N=12. The first number tells the distance between two anchor frames (I or P): it is the GOP size. The second one tells the distance between two full images (I-frames): it is the GOP length. For the example M=3, N=12, the GOP structure is IBBPBBPBBPBBI. Instead of the M parameter the maximal count of B-frames between two consecutive anchor frames can be used."
