802.1R and fast roaming

Hello world.

I couldn't find anything in this regard. I want my customers to be able to experience a better roaming. based on my study the client goes through the process of 802. 1 x if they re - associate with different AP (even on the same WLC) and 802.1r or FT 802. 1 x option seems to be the answer, if I don't want to use CCKM server.

first is that OK? on my debug I get this line which is saying no transfer of data at this stage when its in the process of EAPol.

so to allow 802.1r, I chose the transition quick and on DS and also checked the FT 802.1 x.

is that all?

Thanks for your response

Hello

Thanks for debugging.

By the way I am at the other end of AU (IE MEL) - it was 22:38 when I replied to you yesterday :)

So here's what I found the debug, looks like not fast roaming (802.11r) happen & each time customer is going through the full process Auth & then 4 - Way handshake. I can see 6 times customer roaming to different AP, shows only first 3 here.

Regarding your version of code & 802.11r client supported, I found this during today to WLC 8.0 Delta Webinar.

1 802.11r mixed mode support to 7.6 and 8.0 (both codes)
2. yet few applicants (Mac OSX, Netgear, ect) don't like mixed mode WLAN, so that they can have trouble if you enable FT

Here is the list for 802.11r joint customer supported in OS & view according to webex of today.

I suspect that your Dell customer may not support 802.11r & therefore do the full auth everytime.

If possible get an output of client debugging for an iPhone or an iPad (running iOS6 or higher). We can therefore compare & see the difference.

Hope this answer help me set up my side. :)

  • Wireless 802.11r and Laurette on WLC

    Hi all

    I saw in version 7.4 and later on the WLC5508 you can configure 802.11r and 11 k fast aid Transaction so that iOS7 don't suffer a loss connection for roaming... my question is on the same WIFI network, I can configure 802. 1 X and FT - 802.1 X authentication so that I'll be able to have the same SSID non802.11r and 802.11r compatible client? Or this configuration creates association problem?

    BR

    OG

    Maybe this can help also to explain it:

    http://www.Cisco.com/en/us/docs/wireless/controller/7.3/configuration/gu...

    Legacy clients can not associate with a WLAN which has enabled 802.11r, unless the driver of the supplicant who is responsible for the analysis of exchange of information (IE ARS) robust security network is old and not aware of the suites more in EI AKM. Because of this limitation, customers cannot send connection requests to the local wireless networks. These customers, however, can still be associated with non - 802.11r WLAN. Customers who are capable of 802.11r can associate as 802.11i clients on LANs wireless with 802.11i and 802.11r Authentication Key Management Suites active time. The solution is to activate or upgrade the driver of the legacy clients to work with the 802.11r new AKMs, after which legacy clients can associate with success of 802.11r compatible WLAN. Another solution is to have two SSID with the same name but with security different parameters (IP and non-pi).

    6i would like to know which is the hard drive bigger and faster that I can buy for a T61 (6458-CTO).

    It has a 80 GB hard drive, 5400 RPM and SATA interface (1.5 Gb/s).

    Can I buy a SATA II (3 Gb/s, 500 GB and 7200 RPM) for this computer?

    Thank you.

    Jon

    > Buy a SATA II (3 Gb/s and 500 GB 7200 RPM) for this computer?

    Yes, you can, however, due to limitations in the T61, there only a SATA I interface. This isn't really a problem because the drive itself is unable to transfer data at the maximum speed of the interface.

    Here is an article on what is happening with 4GBs of RAM:

    "If a computer has many features implemented, the available memory can be reduced to 3 GB or less." However, the maximum memory available in 32-bit versions of Windows Vista is typically 3.12 GB. »

    I've updated my Chipset and RAID drivers.

    I uninstalled ASUS ACPI Center who could be one of the causes of this problem, rename the executable to Center asus acpi.

    I ran TuneUp Disk Doctor to verify my RAID and fix problems

    I update and updated my Antivirus ESET Smart Security in order to improve the performance of the process EKRN who sometimes take a large part of the time CPU.

    Can someone advice me how track and what tools to use to run a diagnosis of systemd and check if my problem is with the hardware or the operating system?

    Run process monitor. Stop the trace when your problem occurs. Look through the timestamps of the gaps.

  • Remote Desktop is very slow on one another and fast on a single computer

    While I'm at work, I use remote desktop to connect to my home computer. I did this for a long time without any problem.
    I just finished building my new computer yesterday and install a new copy of Windows 7 Pro x 64. When I went to connect to my new computer today via desktop remotely, it is really slow and jerky. I thought maybe it was just my connection but I tried to connect to an older computer which is also on my network home and it was really smooth and fast. So I have 2 computers on the same network, and they have significantly different results when you connect via RDP. The old computer is significantly less powerful than my new.
    Is there something I need to do on my new computer (the server) to speed things up? Maybe tweaks, I have neglected or forgotten to start because it is a new installation of windows?
    All of the involved computers, Client and server (s) running Windows 7 Pro x 64 and my remote desktop settings are the following:
    Display:

  • IP number looking for PSI - need help with a sql solution better and faster

    Hello

    I have a table (one) with more 1 000 000 IP addresses and numbers (the digital equivalent of the IP address)

    I have a second table (b) which contains a mapping between the ranges of the ISP and IP. The table looks like this and more contains 150 000 entries:

    600000000 700000000 ISP_X

    800000000 900000000 ISP_Y

    I'm creating a third table (c) which connects (a) IP numbers to identify the ISP from (B). The query looks like this:

    CREATE TABLE c

    AS

    Select a.IP_ADDRESS

    b.ISP_NAME

    IP_NUMBERS a, ISP_LOOKUP b lkp

    where a.IP_NUMBER between b.BEGIN_IP_RANGE and b.END_IP_RANGE

  • Ask the operation slow with large SGA and fast with little CMS

    Hello

    We have a situation where one of the insert is running slow and fast QA in PROD. Both are the same versions of database - Oracle 10.2.0.4 on HP Unix 11.31. To avoid the cause of databases running on another server, we copied from our Production database to the same server where the QA database is running and began with init.ora PROD that has 7 GB 6 GB SGA_TARGET and SGA_MAX_SIZE. For the QA database, SGA_MAX_SIZE is 700 MB and SGA_TARGET is 600 MB. Both are running on the same server, and with the same data. We have refreshed QA with data from PROD. If we start with PROD init.ora QA database, QA also behaves the same way PROD.

    This problem is only with the specific insert. Here is the result of this specific statement tkprof. Can someone please interpret this for me? I am poor in SQL tuning :-( Why the statement behaves ODD with the size of the SGA PROD? Generally, we would think THAT larger SGA should give better performance.

    Option 1:

    You run with two different ORACLE_HOMEs - that is potentially two different copies of the Oracle executable to the patch different sets?

    Option 2:

    A change of size of SGA is unlikely to directly affect the execution plan, but it also has change the size of the PGA TOUR at the same time? A change in the pga_aggregate_target could affect the choice of the mechanism of the join optimizer. (But not to change an in a join; but hash semi-join to nested loop is possible).

    Possibility 3:

    The db_file_multiblock_read_count leaves then the size that oracle defines by default depends on the db_cache_size divided by process; so, if you have reduced the sga_target_size you (implicitly or explicitly, no doubt) reduced the db_cache_size, and if you don't reduce the process in the same way, then the default db_file_multiblock_read_count been reduced. What you did on your system stats, this could change the cost of (for example) full tablescans, which could lead to a change in execution plan.

    It would be useful to see the results of a call to explain the plan / dbms_xplan.display in both cases so that we can see the variation in estimates of Oracle.

  • It would be better and faster?

    Please look at the code segments mentioned in "BOLD",

    1)________________________________

    DECLARE
    BOOLEAN my_variable;
    BEGIN
    IF NVL(my_var,FALSE) THEN
    dbms_output.put_line ('Fake');
    ON THE OTHER
    dbms_output.put_line ('Genuine');
    END IF;
    END;

    2)_________________________________

    DECLARE
    BOOLEAN my_variable;
    BEGIN
    IF my_variable = FALSE THEN
    dbms_output.put_line ('Fake');
    ON THE OTHER
    dbms_output.put_line ('Genuine');
    end if;
    END;


    One who performs better and faster?

    If the answer is 2; Why the NVL() function was introduced? {: 8}

    First of all the NVL(my_var,FALSE) IF THEN and IF my_variable = FALSE THEN have different meanings!

    IF NVL(my_var,FALSE) THEN will be true only if the value of my_variable is true
    and
    IF my_variable = FALSE THEN values under this instruction will be executed when my_variable is false!
