WLC from 7.0.116 to 7.4.100 How to avoid H-Reap Problems

Dear All,
I would like to know how to avoid the Cisco H-Reap Problem when upgrade directly, and if it occurs 100% in the upgrade.
7.0.98.0 or later 7.0 releases
You can upgrade directly to 7.4.100.0
Note If you have VLAN support and VLAN mappings defined on H-REAP access points and are currently using a 7.0.x controller software release that is prior to 7.0.240.0, we recommend that you upgrade to the 7.0.240.0 release and then upgrade to 7.4.100.0 to avoid losing those VLAN settings.
Know better workaorund would be other options.
Thanks!
Víctor

Hello,
As per your query i can suggest you the following solution-
You can upgrade to 7.4.100.0 and use flex-connect to resolve the problem. Previously it was known as h-reap.
For more information please refer to the link-

Hope this will help you.

                     wa_empdata_csv-department.
    APPEND wa_empdata_csv TO  itab.
    in the flat file i can see for one of the record for the field Title  as
    Director, Finance - NAR............there by through my code the  wa_empdata_csv-Title is getting splited data as "Director, and  Department field is getting Finance - NAR" , i can see that even though  " Director, Finance - NAR"  is one word it is getting split .
    .......which is the problem iam facing.Please could any body let me know how in this case i should handle in my code that this word
    "Director,Finance - NAR"   wil not be split into two words.
    Thanks & Records

    Hi Madhuri,
    Best way to avoid such problem is to use TAB delimited file instead of comma separated data. Generally TAB does not appear in data.
    If you are generating the file, use tab instead of comma.
    If you cannot modify the format of file and data length in file is fixed character, you will need to define the structure and then move data in fixed length structure.

  • TS1277 cannot play most songs in Libary even though purchase from Itunes store,  songs have astrick in front, how do I fix this problems

    Hi,
    Please help, having problem with Library, had compter crash, got fixed but now cannot play most songs as it has been marked as cannot find file and has astrick in front, most songs were puchased from Itunes, cannot seem to get support from Apple, does anyone have fix, as there is 300 songs not playable, please help,

    The "missing file" thing happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, or that the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout,or vice-versa, and so is looking in slightly the wrong place.
    Select a track with an exclamation mark, use Ctrl-I to get info, then cancel when asked to try to locate the track. Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, or a drive letter has changed, it should be possible to reverse the actions. I can provide a step by step guide if you give me the two paths.
    Alternatively, as long as you can find a location holding the missing files, then you should be able to use my FindTracks script to reconnect them to iTunes.

  • After installing Cooliris and moving icon from Tab Mix Plus Cooliris will not "launch" ; how can I rectify this problem?

    On another computer was causing FF to run sporadic , I believe. I have now installed on a Mac but icon is in b&w and will not launch when clicked.

    If it's slow on startup it would be extensions loading or LaunchDaemons starting up. 
    You should have a look in:
    /Library/LaunchDaemons
    /Library/Extensions
    You can count out anything in your home folder and it shouldn't put anything in /System as that's reserved for Apple. 

  • 5508 WLC Upgrade from 7.0.116 to 7.2.111.3

    I am planing to upgrade 2 of my 5508 series WLC from 7.0.116 to version 7.2.111.3.  I understand that legacy AP's are no longer supported.  Is there any other issues I should be aware of that others have experienced?  Is the upgrade straight-forward just like other code upgrades?  Thank you.

    Thanks so much for all the information.  Afterr reading throught this, it makes sense now.  I do have one more question. After doing a show sysinfo on these controllers, it does look like the FUS does need to be updated.  Should I perform this before I upgrade to version 7.2 code, or after I have peformed the upgrade to 7.2, or does it matter?

  • Steps to update a 4402 WLC from 4.2 to latest 7.x

    Greetings,
    We need to upgrade a 4402 wlc from 4.2 where it is now, to the most recent 7.x release.  I believe this is a 2 step process.  Does anybody know the correct steps to upgrade to?  Obviously we can't just jump straight to 7.x
    Thanks in advance!
    -Zach

    http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn7_0_116_0.html#wp233853
    If you read the release notes a little more carefully, you will also see the following:
    4.2.130.0 or earlier 4.2 release
    Upgrade to 4.2.176.0 before upgrading to 7.0.116.0.
    4.2.173.0 or later 4.2 release
    You can upgrade directly to 7.0.116.0.
    Note If you upgrade from 4.2.176.0 to 7.0.116.0, the upgrade fails for the first time. The upgrade completes successfully when you upgrade again.
    4.2.209.0 or later 4.2 release
    You can upgrade directly to 7.0.116.0.
    Just keep the above in mind depending upon your 4.2 release.

  • Deleted WLC from its folder under the Device work center of Cisco prime 1.2

    I kindly need  your help as regarding cisco prime infrastructure.
    I added the wireless LAN controller to the prime. I later had to troubleshoot the WLC because the reachability status showed UNREACHABLE.
    Due to my troubleshooting, I synched the WLC a couples of times and the collection status has been showing SYNCHING since then.
    I also tried deleting the WLC from its folder under device work center and it deleted but it still reflects under the ALL folder.
    Please would I have to wait for the SYNCHRONIZATION of the WLC to stop before I can completely delete it and re-add??
    Also I noticed that after deploying ''Interface Health'' under Monitoring Configurations, the CPU and memory utilization did not reflect for the devices cisco
    prime is managing.
    What have I missed out?
    Kindly help.

    Prime Infrastructure won't support those legacy models.

  • Removing WLCs from list in NVRAM for deployed LAPs

    Hi,
    Here is a question, which I really would like to have an answer on. I have been searching for this, and can not find any on this. I am up to the point where I start to think it is simply not possible.
    I would like to remove all existing WLCs from NVRAM in my LAPs. Simple, you may think, just boot it without registering and perform the command "clear lwapp private-config", and allthough this is through and I'm sure it will work, it would require me to organize about 300 LAPs to be shipped back to me so I can console into it and perform the command.
    Another thing I thought of was clearing the config from WCS, but I found this only clears the config and not the list of previously joined controllers stored in NVRAM.
    The background of my request is that we started out with WLCs back in code 3.1, and there it was recommended to have one mobility group if you wanted to have an anchor guest controller.
    Today, we are running 5.2 and the number of WLCs we have in place is 21 and growing.
    I believe that since we went to 4.2 we started having problems with LAPs sometimes registering to the wrong controller.
    We have been troubelshooting this a lot, and with the current discoverey mechanism, where the LWAPP discovery respons includes all controllers in the mobility group, and aso the previously joined/learned controlelrs, we do understand why it happens.
    So, the new updated design is to separate into different mobility groups and still make the necessary relationships to the guest anchor controller in the old mobility group. Works all fine. However, it did not resolve the problem of LAPs sometimes registering to the wrong controller.
    And it makes sense if you read the documents, the LAP has learned and stored about all the WLCs in NVRAM, so it can select any, if for some reason the primary fails (it only happens ofcourse when the primary fails).
    So, to ensure it will no longer rehome to another controller, I do need to remove all previuosly learned WLCs from NVRAM, but can not seem to find a way to do this without having console access, and I have about 300 LAPs in different countries, over appr. 30 locations.....
    Help!!!!!
    Thanks in advance for your thoughts on this,
    Leo

    Hi,
    Are you convinced this removes stored information in NVRAM for previously joined controllers. So far, my understanding was that only a factry default reset would do so, not the clear all config.
    I do understand the clear all config does remove entries for primary, secondary and tertiary controllers but I'm still in doubt if that would ensure the AP will not wander to previously joined controllers.
    Kind regards,
    Leo

  • Migrating WLC from existing WCS to another WCS

    Dear tecahers:
    We support a campus with 8 WLC with 600 APs managed by our own WCS.
    Recently we are going to support a new site. They have 4 WLC with about 250 APs managed by another WCS.
    What we want to do is migrate 4 WLC with 250 APs from their WCS to our own WCS, thus we can use our own WCS to manage all the WLC and APs.
    My question is How can we migrate these 4 WLC from the existing WCS to our own WCS with the configuration and maps?
    Any help would be really appreciated.
    Regards,
    Steven

    Do you have enough licenses on the new WCS for the additional access points you plan to add ? As for migration, I recall there arent any migration tools from wcs to wcs. I recall there being tools for WLSE to WCS. Depending on how many maps you have, it shouldnt take all that long to import maps and place aps.

  • Access wlc froma network defined on the wlc

    Hi Guys,
    i have a wlc 2504 with 7.6.130
    My management ip address is 192.168.1.1/24 and i have an interface on the wlc with ip address 192.168.2.1
    From a PC(wired) with ip address 192.168.2.x (network are routed) i cannot access https://192.168.1.1 when i configure on the wlc an interface with ip address 192.168.2.1
    It's look like i cannot access wlc from a network defined on the wlc.
    Can you help me in resolving this issue?

    That is by design. The WLC does not allow access from a configures interface other than management by default. 
    If you need to access the WLC from a configures interface other than management you need to issue the command:
    config network mgmt-via-dynamic-interface enable

  • POE Issues After Upgrade from 7.0.240 to 7.6.100

    We have a 5508 that has just been upgraded from 7.0.240 to 7.6.100 with many 1142's, 3502's, etc. Our wired network is HP 5406zl's POE on every port and plenty of power available for POE.
    As soon as we upgraded our 1142's to 7.6.100 we started getting poe faults on several switchports. The trap indicates an over-current error and the AP will not power up. I can move that same AP to another switch port and some times that will work. If I reboot the switch the faults may clear on those ports, but will reappear on other ports. It is not always the same APs, and not always the same switch ports.
    I have tried downgrading back to 7.0 and the errors clear. Obviously I want to be running the newer code for the bug fixes and features. TAC has not given this case any time yet.
    The switches report more than enough power being available still on the ports.  I can see the ports try to come up, and most of the times the AP will start to power up and come up at 8 watts as it boots, and as soon as the AP is ready to go and starts powering the radios it enters the fault state.
    The APs all run in local mode, and I have tried enabling "Pre-standard 802.3af switches. "
    Does anyone have any ideas? Something must have changed in the way power is drawn or negotiated.

    HI Glenn,
    Go for 7.4.121.0 (7.4MR2) version & see if this issue is there ? If not then it may be a bug/issue specific to this latest code. Here is the release notes for this code
    http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn74mr02.html
    Also makesure your WLC FUS also upgraded to 1.7.0.0. See below & keep note this will take 30-40min downtime to your wireless.
    http://www.cisco.com/en/US/docs/wireless/controller/release/notes/fus_rn_1_7_0_0.html
    The version I have given is the one most people including TAC would recommend
