LWAPP to CAPWAP across different software versions. ?

Hi guys,
I was wondering if someone could clarify what happens when you have controllers live on two different software versions..
We have 4 controllers.. 2 on version 4.2, which APs currently register to with LWAPP and 2 new ones on version 7..
On WCS, I have moved an AP currrently registered on a version 4.2 controller and reassigned it to the newer controller ( ver 7 ).
The AP then reboots and I can see in the event logs that it comes back up on LWAPP after resolving the entry CISCO-LWAPP-CONTROLLER.
On WCS, the AP shows as registered back on the old Controller ( ver 4.2 ) but the Primary and Secondary Controllers are still pointing to newer ones ( ver7 )..
According to the Cisco document, the transfer from LWAPP to CAPWAP should be seemless, so is this a problem migrating across different software versions. ? Will the AP sort itself out eventually.
If I console into the AP and statically assign the new controller IP address, this forces the AP to download the newer software version ( after multiple auto reboots ) and it comes up on CAPWAP.. This shows that the path between the AP and controller is ok..
Ideally, Im hoping that I can simply reassign our current APs to the new controller ( and onto CAPWAP ) rather than having to console into all our remote APs and statically reconfigure them.. Not fun !!.
Any advice would be appreciated..
Thanks.
Jon.

Hi Nicolas,
Thanks for the reply..
Yes I agree that, once on version 7 it will perform a lookup for " cisco-capwap-controller ".. I forgot to say in my original post that I had already check this and it does resolve correctly to the two newer controller IPs.. If I console into the AP and manually define the newer controller IP address, it all goes through sucessfully and I can see the discovery and correct registration process in the logs
So we know that it kind of works but Im hoping that there is a simplier solution from within WCS where I can do all this remotely, rather than consoling into every AP locally.
Your suggestion of inputting the new controller IPs in WCS instead of the names sounds good however, it needs to be on version 7 first to be able to do this ? As you say, there is a field for this in version 4.2.... Looks like there is a bit of chicken and egg going on here !!.
Any other ideas or thoughts would be appreciated.
Many thanks.
Jon.

2 Cisco 2504 controllers but different software versions

Hello,
I am configuring two 2504 controllers, which I ordered together, however they run different software versions and I don't have a contract/ login to download wlan controller software from the Cisco website.
The one with the newest version runs 7.2.103.0 while the other one runs 7.0.220.0
I want to run them together in the same subnet and use them for redundancy (10 AP's will connect)
Is there a way I can download the software from the controller, just like I am able to do with an ASA firewall? Then I can upload it to the controller with the older software version.
Thank you and regards,

Hello Ralph,
No, you can not download the code from the WLC. You can contact your reseller and request the firmware.
If you have a contact with Cisco sales team you can tell them and they can open a TAC case for your behalf to publish you the code.
If your device is under warranty you can send your serial number to [email protected] along with your CCO ID. They will publish you the image if the device is under warranty. (or if it is under valid contract but you don't have the contract number).

Photostream sharing across different firmware versions

I've got a weird problem here:
Person A has an iPad with iOS7
Person B has an iPad with iOS6
Person A creates a photo stream and shares it with Person B - ensuring they turn on "Subscribers Can Post"
Person B joins the stream just fine (and can view photos already there), but cannot add photos to the stream
OK, now the other way around:
Person B creates a photo stream and shares it with Person A - "Subscribers Can Post" is not available as they are on iOS6
Person A joins the stream just fine (and can view photos already there), but cannot add photos to the stream
I'm guessing that the problem here is the server-side validation of whether the "Subscribers can post" option is switched on or not. As Person B has only iOS6 (and therefore the option is not available), it seems to me that this validation fails, meaning each ipad thinks that do not have permission to add photos to the stream.
Can anyone direct me in setting up a collaborative photostream between these devices?

Hello Breame,
Thank you for providing so much detail regarding the Shared Photo Streams you are creating. iOS 7 is required of both participants for a collaborative Shared Photo Stream:
If I am using iOS 6, can I still view photos and videos contributed by subscribers who are using iOS 7?
If you are using iOS 6, you will be able to view photos contributed by subscribers to a shared photo stream by following the steps below. Video sharing and the ability to contribute to other people's shared photo streams requires iOS 7.

AP1231G upgrade to thin-ap & cannot find the "lwapp" or "capwap" command !!!

Dears,
I upgarde the AP1231G to thin-ap!
I want to set static lwapp ip information.
But, The AP not the command "lwapp" or "capwap"?!
Does anyone know where I can find documentation on how to fix this?

I just ran into the same issue with 1230's but only when the AP was on a different vlan than the WLC. What I did was put an ip-helper address on the vlan the ap was on and pointed that to the managment interface of the wlc.
interface vlan
ip helper-address
Then on your L3 device, globally configure the following:
ip forward-protocol udp 12222
ip forward-protocol udp 12222
ip forward-protocol udp 5246
ip forward-protocol udp 5247
I don't know what version you are running and if you are running secure or not. After the AP's join and download the firmware, you can remove these.

MX 800 - Downgrade software version

Hello,
Is it possible to downgrade the software version of the MX 800 to TC.6.3.
For information, the MX 800 is by default TC 7.1.2.
Please help.
Thx

If you go to the MX800 software download page, the listed software versions are the only versions that can be installed on that particular device. As Jonathan noted, each codec or series of codecs have a specific TC software file number, meaning you can only install the software that matches the file number relevant to the codec you're installing it on. It's confusing I know, but it's because as codecs evolve, such as OSD interfaces or features change, and not all features will work on all codecs, they need some way to change and/or limit these items across the different platforms.
As Jonathan had suggested, if you want or need to register in H323, you'll have to not us SIP, as the MX800 is single stack only, meaning it can only register using one protocol, not both.

HT1947 Remote app requirements are stated as "software version 3.1.3 or later". I am running 4.2.1 and when I try to download it says 4.3 required. Where can I get the (old) version that runs on my IOS?

'Remote' app requirements are stated as "software version 3.1.3 or later". I am running 4.2.1 and when I try to download it says 4.3 required.
OK, I understand that new versions make use of facilities that come with new versions of IOS, but there is/was a version that runs on 3.1.3 and therefore, I assume 4.2.1. Where can I get the (old) version that runs on my IOS?
The app store seems to ignore all legacy equipment owners, and want me to spend loadsa money to get the latest shiny toy. It probably makes business sense, but I dislike companies that take that approach. This is my first venture into smart phones, and I like the IOS interface, but I'm not sure I can afford the maintenance.

The app store seems to ignore all legacy equipment owners, and want me to spend loadsa money to get the latest shiny toy. It probably makes business sense, but I dislike companies that take that approach.
This is standard for Apple. While there is little official mention of the software support lifespan for equipment, typical support has been about 4-5 years for computers. It strikes me that newer items, especially mobile devices, are not built as sturdily nor do they have the hardware upgrade capabilities required to keep up with newer systems. When we bought an iPhone 4S we were told by the person in the store we'd probably be looking at a newer model in two years. The iPhone 3G could be anywhere from 2 to 4 years old, putting it well into.
As for app availability, Apple typically pulls old software versions from its site when new versions appear. If it is a non-Apple app then I guess it is up to the vendor. It is indeed tiresome but it is not at all unusual. Since I only ever run used Macs, I download current versions even though my computer won't run them, stick them on a hard drive, then I have them when I upgrade to a newer used computer. If you run older equipment you have to learn a different mode of operation to exist with the Apple 'new and innovative' but 'forget about the old' philosophy.

How do I fix colour picker to work across different colour-managed monitors?

Hey everyone!
I'm assuming this problem I'm having stems from having colour-calibrated monitors, but let me know if I'm wrong!
To preface, this is the setup I have:
Windows 7
3 monitors as follows, all have individual colour profiles calibrated using the Spyder 3
Cintiq 12WX
Dell U2410
Dell 2409WFP
Photoshop CS6 - Proofed with Monitor RGB, and tested with colour-managed and non-colour-managed documents
I usually do most of my work on the Cintiq 12WX, but pull the photoshop window to my main monitor to do large previews and some corrections. I noticed that the colour picker wouldn't pick colours consistently depending on the monitor the Photoshop window is on.
Here are some video examples:
This is how the colour picker works on my Dell U2410: http://screencast.com/t/lVevxk5Ihk
This is how it works on my Cintiq 12WX: http://screencast.com/t/tdREx4Xyhw9
Main Question
I know the Cintiq's video capture makes the picture look more saturated than the Dell's, but it actually looks fine physically, which is okay. But notice how the Cintiq's colour picker doesn't pick a matching colour. It was actually happening the opposite way for a while (Dell was off, Cintiq was fine), but it magically swapped while I was trying to figure out what was going on. Anyone know what's going on, and how I might fix it?
Thanks for *any* help!
Semi-related Question regarding Colour Management
Colour management has always been the elephant-in-the-room for me when I first tried to calibrate my monitors with a Spyder colourimeter years ago. My monitors looked great, but Photoshop's colours became unpredictable and I decided to abandon the idea of calibrating my monitors for years until recently. I decided to give it another chance and follow some tutorials and articles in an attempt to keep my colours consistent across Photoshop and web browsers, at least. I've been proofing against monitor colour and exporting for web without an attached profile to keep pictures looking good on web browsers. However, pictures exported as such will look horrible when uploaded to Facebook. Uploading pictures with an attached colour profile makes it look good on Facebook. This has forced me to export 2 versions of a picture, one with an attached colour profile and one without, each time I want to share it across different platform. Is there no way to fix this issue?
Pictures viewed in Windows Photo Viewer are also off-colour, but I think that's because it's not colour managed... but that's a lesser concern.

I think I've figured out the colour management stuff in the secondary question, but the weird eyedropper issue is still happening. Could just be a quirk from working on things across multiple monitors, but I'm hoping someone might know if this is a bug/artifact.
Going to lay out what I inferred from my experiments regarding colour management in case other noobs like me run into the same frustrations as I did. Feel free to correct me if I'm wrong - the following are all based on observation.
General Explanation
A major source of my problems stem from my erroneous assumption that all browsers will use sRGB when rendering images. Apparently, most popular browsers today are colour-managed, and will use an image's embedded colour profile if it exists, and the monitor's colour profile if it doesn't. This was all well and good before I calibrated my monitors, because the profile attached to them by default were either sRGB or a monitor default that's close to it. While you can never guarantee consistency on other people's monitors, you can catch most cases by embedding a colour profile - even if it is sRGB. This forces colour-managed browsers to use sRGB to render your image, while non-colour-managed browsers will simply default to sRGB. sRGB seems to be the profile used by Windows Photo Viewer too, so images saved in other wider gamut colour spaces will look relatively drab when viewed in WPV versus a colour-managed browser.
Another key to figuring all this out was understanding how Profile Assignment and Conversion work, and the somewhat-related soft-proofing feature. Under Edit, you are given the option to either assign a colour profile to the image, or convert the image to another colour profile. Converting an image to a colour profile will replace the colour profile and perform colour compensations so that the image will look as physically close to the original as possible. Assigning a profile only replaces the colour profile but performs no compensations. The latter is simulated when soft-proofing (View > Proof Colors or ctrl/cmd-Y). I had followed bad advice and made the mistake of setting up my proofing to Monitor Color because this made images edited in Photoshop look identical when the same image is viewed in the browser, which was rendering my images with the Monitor's colour profile, which in turn stemmed from yet another bad advice I got against embedding profiles . This should formally answer Lundberg's bewilderment over my mention of soft-proofing against Monitor Colour.
Conclusion and Typical Workflow (aka TL;DR)
To begin, these are the settings I use:
Color Settings: I leave it default at North American General Purpose 2, but probably switch from sRGB to AdobeRGB or ProPhoto RGB so I can play in a wider gamut.
Proof Setup: I don't really care about this anymore because I do not soft-proof (ctrl/cmd-Y) in this new workflow.
Let's assume that I have a bunch of photographs I want to post online. RAWs usually come down in the AdobeRGB colour space - a nice, wide gamut that I'll keep while editing. Once I've made my edits, I save the source PSD to prep for export for web.
To export to web, I first Convert to the sRGB profile by going to Edit > Convert to Profile. I select sRGB as the destination space, and change the Intent to either Perceptual or Relative Colorimetric, depending on what looks best to me. This will convert the image to the sRGB colour space while trying to keep the colours as close to the original as possible, although some shift may occur to compensate for the narrower gamut. Next, go to Save for Web. The settings you'll use:
Embed Color Profile CHECKED
Convert to sRGB UNCHECKED (really doesn't matter since you're already in the sRGB colour space)
and Preview set to Internet Standard RGB (this is of no consequence - but it will give a preview of what the image will look like in the sRGB space)
That's it! While there might be a slight shift in colour when you converted from AdobeRGB to sRGB, everything from then on should stay consistent from Photoshop to the browser
Edit: Of course, if you'd like people to view your photos in glorious wide gamut in their colour-managed browsers, you can skip the conversion to sRGB and keep them in AdobeRGB. When Saving for Web, simply remember to Embed the Color Profile, DO NOT convert to sRGB, and set Preview to "Use Document Profile" to see what the image would look like when drawn with the embedded color profile

How to Launch an Integration Builder under two different java versions

How to Launch an Integration Builder under two different java versions     1
1. Situation     2
2. How To Do     2
2.1 jre preparation     2
2.2 Put them into the system     2
2.3 Execute a Java Web Start under jre 1.4.x version     3
2.4 Change Java Runtime Versions     3
2.5 Launch an Integration Builder     6
1. Situation
OS: windows 2000 pro English
Java version: jdk 1.5.x was already installed. (Its not permitted to change.)
I dont have any authorization to install any software on the PC.
But I need to use an Integration Builder.
I already knew URLs of an Integration Builder (http://<hostname>:50000/rep/start/repository.jnlp).
2. How To Do
At this moment, an Integration Builder (XI 3.0) can be launch under jre 1.4.x environment (on windows).
2.1 jre preparation
I download j2re-1_4_2_10-windows-i586-p.exe from http://java.sun.com/j2se/1.4.2/download.html
I installed it on my home PC and copied all files from C:\Program Files\Java\ j2re1.4.2_10\ into my USB.
2.2 Put them into the system
I pasted j2re1.4.2_10 folder from my USB into the windows 2000 pro system.
Finally, I could list up all of javaws.exe under this system.
c:\j2re1.4.2_10\javaws\javaws.exe
c:\Program Files\Java\jdk1.5.0_05\bin\javaws.exe
c:\Program Files\Java\jdk1.5.0_05\jre\bin\javaws.exe
c:\Program Files\Java\jre1.5.0_05\bin\javaws.exe
2.3 Execute a Java Web Start under jre 1.4.x version
I executed c:\j2re1.4.2_10\javaws\javaws.exe .
2.4 Change Java Runtime Versions
Go to File-> Preferences -> Java
As you can see, it indicates 1.5 version.
Click [FIND] button.
Click [NEXT] button.
Click the j2re1.4.2_10 folder.
Click [NEXT] button.
A JRE Finder is able to find javaw.exe automatically. Or you can indicate C:\j2re1.4.2_10\bin\javaw.exe directly.
Click [NEXT] button.
Finally, there are two Java Runtime Versions. Now you need to uncheck the Enabled column of 1.5 version and check 1.4 version.
Click [OK] button.
Well, in the General tab, I selected None for Proxies.
2.5 Launch an Integration Builder
In the Location field, I typed the URL of an Integration Builder jnlp.
http://<hostname>:50000/rep/start/repository.jnlp
SAP Integration Builder comes up inside Applications area.
Select it and click [Start] button.
If you click Environment-> Integration Builder (Configuration), you can launch Integration Builder: Configuration.

I am not getting anywhere with deploying my application or
applet.
I have set up my bc4j project. It contains all my VO info,
links, application module. (proj a)
I then have another project with DbInfo in it(has all my rowset
info), Multiple Frames, and my Applet.java file.
Actually I have an Applet.java file and a Application.java file
because I was seeing if both/either worked. Anyway they seem the
same, except for that extra window that comes up when you run the
applet.
I follow the steps in the oracle directions (from earlier post).
And all seems ok. But at ---->
[*] Select the subdirectory under myhtml where your applet's HTML
file
is located, and enter the directory path of the 'staging'
directory you
created in step 3 above, if different from the default.</li>
[*]Select the HTML files that JDeveloper created to run your
applet.</li>
[*]Select all of the Java source files in your project that make
up the
applet.</li>
I have no HTML file associated with my applet, at least that I
know of.
So do I need to create one, or should it of been done
automatically.
Also, I trying to figure out what will be the best way to deploy
my project. Applet or stand alone application is what my first
choices have been so far. I have read that there is some issues
with applets being served from a different server than the
database. So a stand alone application was my front runner, but
I haven't gotten either way to work yet.

What is the best way to migrate to a new computer and software version?

New computer, new software version. Brand new MacPro with OS X v10.9.4 and Pegasus Promise 24 TB R8 Raid 5. Old machine would only run FCX v10.0.9. All project and media files on eSATA drives hooked up to (really) old MacPro. No room to make copies on that system.
Ready to start copying projects and events to the new machine via ethernet cable hookup. Haven't yet updated FCX to the latest version on the new machine. Need some advice first.
What would be the most efficient method of getting the many terabytes of events and projects transferred to the new machine? Should I copy everything via FC instead of the finder on the old machine and then try to relink media, or Just use the new machine to suck everything over to the Pegasus via the finder and update FC and use the new media management features to to relink? Or is there a means of transferring the data without loosing the links?
My head is spinning! Feels like there are bees living in there.
Any and all suggestions welcome.
Jimbo

You also need to ask yourself how many of the old projects you really need to copy across.
We tend to get very attached to our old projects and don't like to trash them "in case we need them in the future".
Frequently we don't require them any more and they just litter our systems.
As long as you keep copies of the original media on the SD cards/tapes, you can always revisit them, albeit with a bit of work . . . though I generally find that repeating a project is much quicker than the original as most of the edit decisions remain in your memory.

My computer crashed and I need to reset up my phone. Iphone 3 running software Version 4.2.1

My computer crashed and I need to reset up my phone. I do not have a backup. Iphone 3 running software Version 4.2.1
After researching this, I understand that I will need to reload iTunes on a new computer, deactivate the prior computer and authorize the new computer with iTunes. I can then restore any apps and music purchased through iTunes. (Insert Question 1 Here.) Then Sync the phone with the new account, taking care to do it manually so as not to overwrite the information on the phone. This should restore the apps and music to my phone. (Insert Question 2 Here.) This process will not restore photos (Insert Question 3 Here.) I would like to over write my current phone calendar (start fresh remove all appointments) and have it sync with a different iTunes. (Insert Question 4 Here) .
Am I forgetting anything or misunderstanding anything? Thank You!
Question 1: Apple help states that you can download previous purchases directly to phone with iOS4.3.3. Then later states that iOS 5 or later is required for iPhone (CDMA Model). ON this page http://support.apple.com/kb/HT2519 I am still running Version 4.2.1 on my iPhone 3. Will this cause difficulty with restoring apps and music (purchased through iTunes) to my phone?
Question 2: What happens to data stored in the apps within the phone? Like password information stored in Splash ID, Files Stored in Air Sharing, or photos stored in a separate app (not the standard photo library)?
Question 3: Will the photos in my iPhone standard library be deleted when I sync? Does anyone know of a way to save them other than emailing them to the computer, prior to syncing?
Question 4: Is it possible to have my calendar and contacts sync at my office computer and have the other items sync to my personal home computer? How does that affect my restore process? I want to ensure the contacts are NOT deleted, but I want the calendar to be overwritten and start fresh.

The software update process does not touch any user data or settings. Fact is, merely updating your software should not have deleted your contacts. Something else is going on here. First of all, the only signed firmware available for your phone is iOS 4.3. So, how were you able to update to iOS 4.2.1, since that is no longer available from Apple? First thing done when you update software is an iPhone backup. Included in that backup are your contacts. Connect your phone, iTunes running, DO NOT SYNC, right-click your phone in the left device pane & select "Restore from Backup". Select the backup made when you started to update your phone. Note: this will also install iOS 4.3 on your phone.

IPod Updater 2006-06-28 Software Version 1.1.2 causes video lock up

My 5th generation iPod was working fine until I loaded this update. I had it spontaniously reset twice in a row while playing two different video podcasts. The last 3 videos I've tried will cause it to just lock up after a minute or so and I have to reset it.
Is there a way to go back to software version 1.1.1 without restoring back to factory defaults? It would take over a day to reload 50GB back to my iPod over a USB 1 connection. Is there any other fix to this reset and lock up problem?

Same thing happened to me (well my 30gb video iPod XD) And to a lot of people, apparently. My iPod has been comatose (I REFUSE to say it's dead) since Monday after the iPod Update. It's NEVER had problems before, so I lay the blame on the Update. It took forever to "update" (I had it in for hours) and when I finally dced it (prematurely apparently?? I don't know how leaving it in a couple hours and then taking it out makes it premature but okay iPod Updater...) it flashed to the Apple screen, which I then reset, and now it's in its comatose state
I have really nothing to contribute but to say it's happened to me, too XD I've had no luck at other threads so if anyone could help, it would be much appreciated Thanks

Certain apps will not install on my iPod touch 1G due to software version

I bought an iPod Touch 1G off a friend recently. When I got it off him, it had several versions of Angry Birds which all functioned perfectly. Since having to erase all the data and the apps on the device in order to sync it to my computer, I don't seem to be able to install Angry Birds at all and when I try, I get an error message saying I need to update the software version to iPhone 4.
According to my iTunes it is currently on the latest software version which is 3.1.3.
I don't understand why I can't install applications that were working fine before I synced the device to my computer. Could it be some cross-platform issue between my friends Mac and my Pc?
If anyone has a solution, I would be grateful as this is getting frustrating.

First of all, the 1st generation Touch can only instal and use up to iOS 3.1.3, even though there are later versions of the iOS available for newer iPod Touchs. The 1G simply isn't capable of using iOS 4.
As for Angry Birds, there appear to be six versions available (in the UK store), three are paid for and three are free. However, of the three free versions, two require iOS 4.0 or higher to run. So the versions installed on your iPod when you bought it must have been paid for or Angry Birds Lite. I assume therefore that you have been trying to instal Angry Birds Free and Angry Birds Rio Free, which both require iOS 4.0.
I have no idea why there are six different versions or why some require a higher version of the software than other versions.
So either try installing the Angry Birds Lite or buy one of the other versions. Be aware though, that if a version you buy then gets updated and subsequently requires iOS 4, it will be removed from your Touch (as it will not work).
