Wlc 4404 upgrade

Hi, looking for advice on which code to upgrade to. We have a wlc 4404 using mostly AIR-AP1231G-A-K9 access points. The current code is 4.2.130.0. We would like to use some of the 1141 APs and I understand they need at least 5.2. My plan would be to go to 6. I believe I need to go to 4.2.176.0 first and then to 6. The question would be what version of 6 would be the best?  Right now 6.0.182.0 (ED), 6.0.188.0 (ED), and 6.0.196.0 (ED) are available.

Well that is a tricky question and really depends on a lot of variables.  We have installs with all three versions of the software.  Currently I would have to say that 6.0.188.0 is one to try.  We have upgraded some clients to 6.0.196.0 because of issue with the 6.0.188..0, but again, it all depends what equipment you have and if you see any issues with the 6.0.188.0.  Some people I know have just went right to the 6.0.196.0 code and have not seen any issues.  The 6.x is still pretty new in my book, but like you already did..... review the caveats on the different versions and if you have a spare WLC,do some testing.

  • WLC 4404 Upgraded to 7.0.235.3 (WPA HandShake Timeout) not availbale

    Greetings,
    Just upgraded my Cisco 4404 WLC's to 7.0.235.3, the upgrade went just fine. My problem is when I either Telnet or SSH to my Lightweight AP's and run the "DOT11 WPA Handshake Timeout 1000" command the AP doesn't recognized this command. This is one of the reasons I upgrade my WLC's.I have several wireless printers that are passive and are heavily used and keep getting disassociated because they don't respond in time.
    Any Help would be greatly appreciated.

    that command is for IOS AP, not for the WLC. 
    Q.    How do you change the Wi-Fi Protected Access (WPA) handshake timeout   value on a Wireless LAN Controller (WLC) through CLI? I know I can do this on   Cisco IOS® Access Points (APs) with the dot11 wpa handshake   timeout value command, but how do you   perform this on a WLC?
    A. The ability to configure the WPA-Handshake timeout through the WLCs was       integrated in software release 4.2 and later. You do not need this option in       earlier WLC software versions.
    These commands can be used to change the WPA Handshake timeout:
        config advanced eap eapol-key-timeout
        config advanced eap eapol-key-retries
    The default values continue to reflect the WLCs current       behavior.
       - the default value for eapol-key-timeout is 1 second.
       - the default value for eapol-key-retries is 2 retries
    Note: On IOS APs, this setting is configurable with the dot11           wpa handshake command.

  • Wlc 4404 upgrade software version

    I have two wireless controllers ( software version 5.1.151.0 ) . Is this vesion supports AP 1142 N   .
    also what is the required  version to support AP 1142 N .
    If the controllers upgraded to new version , will it affect the APs license for existing software version or no .
    regards,

    But I would recommend you going to the latest 7.0.230.0.
    Using this now.  During the upgrade from 7.0.220.0 to this version, I nearly had a heart attack!  The upgrade of the "ER" was fast, no worries.  The upgrade of the firmware, took AGES!  Next, when the WAPs rebooted, they downloaded and rebooted TWICE!

  • Upgrade BootLoader on Cisco WLC 4404

    What is the latest Bootloader for the Cisco WLC 4404?  And where can I download it?
    My current versions are:
    Product Version.................................. 5.2.178.0
    RTOS Version..................................... 5.2.178.0
    Bootloader Version............................... 4.0.206.0
    Also is there a reason to upgrade the bootloader image?
    On this webpage http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00805f381f.shtml it shows the steps to upgrade WLC are :
    This sequence is recommended for your WLC software upgrade:
    Upload a backup of your controller configuration to a TFTP server.
    Disable the 802.11a and 802.11b/g networks on your controller.
    Upgrade the primary image on your controller.
    Upgrade the boot image on your controller.
    Note: This is a required step for upgrades to 4.1 on the WiSM, 3750G Wireless LAN Controller, and 4400 Series Controllers.
    Re-enable the 802.11a and 802.11b/g networks on your controller.
    I get the primary image is just going to be AIR-WLC4400-K9-6-0-196-0.aes.  But where do i download the Bootloader and it looks like i just do the same thing i did with the primary image.
    I think I am missing something.
    Thanks

    The boot software image consists of the controller boot kernel and           boot menu script. that is.. when you use the WLC for the first time. then you will be able to use this while entering the username, mobility information.. interfaces informations etc.. the Software version is the one which you issue CLI  commands...or even simple example wil be.. reboot the WLC and hit ESC.. the software that you access at this time will be boot loader..
    to upgrade the bootloader...

  • WLC 5508 upgrade

    Hi All,
    We currently have 4 x WLC 5500 (AIR-CT5508-K9) V01 and V02
    So two in  one datacenter and the other two in another datacenter. They are connected via Mobility group to and BOYD open wifi with an Anchor WLC the other 1.
    All four of them are 7.4.110.0 and the APs we use are AIR-LAP1142N-E-K9  and AIR-CAP2602I-E-K9.
    We are looking to get 2700 or 3700 AP so we can use 802.11ac, but we need to upgrade all WLC to  7.6.130.0.
    1. is it a direct upgrade from  7.4.110.0 to 7.6.130.0?
    2. If I upgrade one datacenter one weekend and the other next weekend, during that week two WLC would be 7.4 and other two 7.6 would it break or cause issue with Mobility group to and BOYD open wifi with an Anchor WLC?
    3. Can any please provide step to step guide for the upgrade from 7.4 to 7.6?
    Many Thanks
    appreciate it :)

    Hi Rasika,
    Many Thanks for your reply and help!
    1. In regards to Upgrade the FUS, is it required to be upgraded once the WLC are upgraded to 7.6 or is just good practice?
    2. Or I can I upgrade the FUS another time?

  • What settings need to be set for the fastest roaming on my wlc 4404

    Hi all
    I notice that on my WLC 4404 when walking around with my laptop, I am dropping pings when it roams to another access point, Is there anything on the controller I need to check, and can I optimize these settings for roaming?
    cheers
    carl

    Hello Carl,
    to have romaing working fine you need to be sure of following:
    1) RF designed correctly , and enough overlapping is availble between the AP's.
    in addition for environment to be free from external noise..
    this can be confirmed with spectrum expert site survey
    2) what authentication and encryption used ( WEP , or WPA-PSK no need to check this point ->> skip :-) )
    if you are using any authentication like 802.1x ->> then enable CCKM on the WLAN to make more seamless roaming.
    3) if more than one WLC availble on site , configure mobility group between them,
    so if client roam from one AP in WLC 1 to AP on WLC 2 ->> no disocnnection observed....
    Kind regards

    Hi Scott,
    You are right i am not able to detect rogue APs because i disabled the RLDP. but when i enable the RLDP for that particular AP. i got the following messages with interface go up and down

  • Wireless clients load balancing on the APs on WLC 4404

    Hi Experts,
    I'm just wondering if the WLC 4404 with firmware 4.2.207.0 can load balance the wireless clients on different WAPs. Let's say that an AP is already handling 15 Wireless devices. When the 16th is trying to join, the controller somehow puts it on another nearby AP, even the signal from this AP is weaker. I heard the similar feature on other Wireless solution vendors. I'm just wondering if Cisco has the similar feature or not.
    Thanks!

    Yes it is known as aggressive load balancing sending a code 17 making the wireless client to loook at another nearby AP.
    here it is the documentation:

    (2) Should I or do I need to upgrade Cisco NCS, 1.1.1.24, after the WLC firmware upgrade?
    (3) SHould I or do I need to upgrade CIsco MSE to latest version?
    Thanks,

    (1) Should I upgrade the foreign controllers first or anchor controllers first?
    Does not matter the order.
    Make sure you upgrade the FUS to 1.9.0.0 version as well

    Does anyone know of a way to clear the load balancing statistics from a WLC 4404?  I've looked through the gui and CLI and can't seem to find a way to do it.
    Thanks,

    You can do a 'show summary' to see the number of connections that have been sent to each servers.
    You can't see the number of bytes so.
    I would suggest to collect this info on the server.

    I am new to Cisco wireless and would appreicate any help with replacing WLC 4404 with 5508. I mean any link or doc (best practices).
    Thansk,

    [email protected]

    Yup, what said Scoot said .. Add the 5508 to the aps high availability. If you have WCS/NCS you can push this to the APs.

  • Decrypt Errors - WLC 4404

    Hello,
    We recently had a few clients being locked down with countermeasures by our WLC 4404 due to TKIP-MIC errors. After doing some reading on the benefits of AES over TKIP I switched our WLAN security settings to AES, and pushed a new wireless policy to our client machines. Every thing appeared to work well, except now the trap log on the 4404 is showing a LOT of WPA decrypt errors. I've checked a few of the clients that appear to have problems, but they've got the right policy and WPA settings to match what is on the WLC.
    It's not one particular NIC, it's various clients.
    Any thoughts on how I might clear these up?
    Rob

    One reason for that is configuration of two WEP keys on a single WLAN is not supported. Currently WLAN can only take one WEP key.

  • WLC Code Upgrade

    We just got a WLC 4002 with 3.2.150.10 software version. I have followed a procedure to upgrade and I know I need to follow this path 3.2.150.10->4.1->4.2.176.0->5.2
    However, I have tried to transfer the 4.1.185 on my controller and I get a
    TFTP Failure while storing in flash!
    error.
    Has anybody experience this?? any adive?

    1. You could be either using a TFTP server that could not support file transfers greater than 32 MB (if this is the case, go to http://tftpd32.jounin.net/tftpd32_download.html and use TFTP32).
    2. Looks like you were upgrading the firmware without upgrading the Bootloader (ER).
    Using the same process as the firmware, download and install Bootloader (in the follwoing order)
    AIR-WLC4400-K9-4-1-171-0-ER.aes before you install firmware 4.1.185. Then
    AIR-WLC4400-K9-4-2-61-0-ER.aes and install AIR-WLC4400-K9-4-2-61-0.aes. Finally, install Bootloader
    AIR-WLC4400-K9-5-2-157-0-ER.aes before you install the final 5.x firmware you want.
    Sorry, it's a very long process but it's the only way.

    Hello,
    I have to manage a wlc 4404. According to me he acts strange.
    Only ports 1,2 and 3 are connected. The ap-manager and the management are linked at port 1. So far so good.
    If I look at the wireless-tab I see all AP's are connected at port 3 !!
    All the 3 ports are connected to the same switch and VLAN.
    AP=Cisco Aironet 1130AG with a default config
    Could someone explain me why all AP's are connected on port 3, while the ap-manager is linked at port 1.
    Thanks in advance,

    The Cisco docs clearly state that you can only have 48 APs associated to each ap-manager interface. If you are not running LAG, and I can't think of a good reason not to, then you will need 3 physical interfaces to be configured with unique ap-manager ip addresses in order to register 100 APs. Since the APs point to the management ip (via DNS or DHCP) to get the ap-manager interface, they will automatically load balance.
    Note that unless you are running VERY recent code, there are significant ARP bugs related to the additional ap-manager interfaces responding to ARP requests. The best-practice is to add a static ARP entry in the router/L3 switch that is the ap-manager's default-gateway. This is an artifact of the ap-manager interfaces not responding to any traffic accept LWAPP, including ARP. This has been a serious problem for a lot of enterprise customers because this impacts most CEF switching devices like the Catalyst 6500 since most IOS versions also have a CEF adjacency/ARP timeout bug.
