3702 AP loss connectivity to WLC in local mode

Hi Experts,

I have an AP 3702 which loses connectivity to the WLC and line protocol goes down.

PoE is always present on the connection to the switch, but only to 15.4 instead of the full 16.8 as with normal operation 3702.

There are 8 other 3702 AP this floor who have no problem.

"Could arp not the ip address of the controller, try again later" is a common phenomenon in their newspapers so I don't think it has any bearing on the issue with this particular access point.

All 9 x 3702 are connected to a switch of edge double accommodation 3750 X battery via 3 x 3560CX in the ceilings.

If I close and (after some time) put to the port of the switch, the AP will get back in touch with the WLC, but then drop again as before in an hour or two.

I deleted the config on the AP and let it sit in mode monitor/sniffer for a few days and he stayed until perfectly so I thought everything was ok. I've reconfigured to accept clients, and since then, it has dropped again.

Hope that this is not a hardware failure and your advice is really appreciated.

Thank you

Messages above give me the feeling that there is a problem with communication between the physical network of the access point connection and control software. This can be hardware and associated software. Your best bet to analyze tracing messages is TAC, so my advice is to connect a case and let send them your registration. The 3700's have "limited lifetime warranty" so you can ask a new in case it is broken (even without a smartnet) you have to wait at least 10 days. Keep us informed about the solution! Please rate helpful messages... :-)

  • Close connections to database in local mode

    I am trying to familiarize themselves with the integration API and I'm having a problem where database connections seem to be left in a State open despite the output of the process.

    My code is implemented to call Session.logout in a try/finally block, but this does not seem to close database connections. When I first wrote my code for a simple command line tool to lay the groundwork for a project, the tools would be hang after completing the main() method because of the expectation of background threads. I've added a call to System.exit at the end to complete these threads and lets out, but this seems to be out without informing the database that the connection must be closed (according to our database administrator).

    I looked around the Javadocs and I see all the methods that looked like they stop background threads properly and allow them to clean up.

    This code is run on P6 Pro version 8.4. The database is MS SQL Server 2008.

    It turns out that the database administrator was not the correct check for active sessions. He was looking for lines regardless of the value of the DELETE_SESSION_ID column in the USESSION table. The sessions where I was told were active were actually removed from the sessions that had not yet been cleaned up by the data_monitor/DAMON background process.

    You should make the fix McAfee, if necessary. There are corresponding communications for their enterprise products.

However, when I checked it says he was doing routine checks the updates in vain when I told it to do a manually. So stick with McAfee you don't follow their procedure of fix would have upgraded my PC at risk by not updated and, like other McAfee ads have since explained, the application did not refer to its database of threats correctly [and this could explain part of the variability of the symptoms of failure but all involved loss of internet connection]. Actually, I removed McAfee then installed Microsoft Security Essentials rather & my answer IE is faster I knew it [even though I had the Add-ons McAfee disabled for centuries].

  • I can not get information about the location of the images geotagged - the message is "unable to establish a network connection to Windows Live Local". Previously, I had a lot. Suggestions? Thank you.

    After a lot of use of this feature of Pro Photo Tools to secure the location for my images geotagged information, I am not not able to do. The error message indicates, as seen above, I am unable to connect to "Windows Live Local." I have Windows XP Pro with service pack 3. I reinstalled Photo Pro and nothing has changed. My Images are jpeg. But being the difficulty in logging on to Windows Live Local, these things, I think, are not important. Any suggestions? Thank you.

  • Local mode and server transfer

    Hello

    Do I absolutely need a transfer server configuration in order to make the Local Mode with VM fully funded (not linked Clones)?

    Currently, I don't have a forwarding server configuration and while he was trying to "verify" a virtual machine, it fails and cannot connect to the ESX host... I guess it is the firewall between the VM and the ESX blocking, but none of my Firewall admins are currently available to check. I also searched the view guide administration of 4.5 for ports associated with local mode and is not listed.

    Thanks for the help.

    Yes, you will transfer server. It act as a Web site that has stored the vmdk and allows the customer to local mode download and resume features. the forwarding server must be in the vcenter that is connected on the view connection server.

  • local mode for the service payment behaviour

    I'm a little confused mode how local is supposed to work.

    When my application calls paymentservice_purchase_request, no cases of paymentservice is generated.  Is this normal?

    Also, when the local mode is enabled, paymentservice_get_existing_purchases_request will fail.  Is this normal too?

    Should not be the case, the API should be forward compatible, but a quick test would confirm.

  • get existing purchases - local mode

    Hi, I tried to implement IPA in my game, and I seem to have some problems with getting existing purchases. When the application starts (local mode), the paymentservice_get_existing_purchases_request (real... 260 (communication delay) returns an error that makes sense and then paymentservice_get_existing_purchases_request (fake.. runs successfully, but he would remember never any purchase that was made when the game was running previously. It would be however, remember correctly all the purchases that were made in this session. But if I close the application and run it again, it wouldn't remember any purchase.

    Is that how it is supposed to work in local mode? Is that how it is supposed to run when running online.

    As stated in the documentation:

    'allow_refresh '.

    If true the device should be given to update the list of purchases from the Service of payment server, if false, the current list of cached purchases must be returned immediately. »

    I guess what I'm asking is which is the allow_refresh setting is disabled, so that the function returns exactly? What is this cover contains between the time where the application has been installed or only from the current session?

    Any help is appreciated.

    Thank you!

    App World of cache is the cache of your browser, it is nice to use when it is available, but should not be invoked. The cache can be deleted at any time, for example, if the device is still low on memory.

    Your application must keep track of purchases, it should not be necessary to check purchases every time it is executed, but you can use the cache for quick control, if the info is available then your app could use it (ex after a reinstall of the application) otherwise it would be probably better to update and also pre-cache all purchases in your application as well.
