8510 s that slow down all L2 networks, that they will connect
One of my first 8510 deployments went horribly wrong over the past two days. For 6 weeks, was stability. This week, suddenly the time of ping for controller - all interface - is of the order of hundreds of milliseconds and the traffic of users reflects the same latency. Failover to the PSO partner makes no difference. Remove all but a uplink makes no difference. If I stopped momentarily uplinks and bring them back, ping times go back to back to 1ms as it should, during the hours as a pair box gets busier latency returns, and 5508 s on the same networks with uplinks identical trunks do not have something like what is happening. 8510 s are easy cabotage on the CPU and memory.
I have put lag in place on these, but TAC says it shouldn't matter. I have another pair with OFFSET configured that doesn't show the same behavior. I intend to make LAG, but the behavior seems just buggy. A generation of 8.0.110.9 climbing - 5508 s random reboot.
Never seen this kind of condition? Is without doubt that between our connected firectly Nexus 7 K and the 8510 pair, and not a matter of circulation as the 5508 s on the same subnet have no similar problem. Using the Cisco SFP.
I do not see it so far and have a pair of 8510 s in HA - SKU connected to a Nexus 7 K. Currently, they have only single interface of 10 GB each connected.
That installation is running 8.0.110.0.Have that monitor you the k 7 ports to see if they are being saturated?

I have a Toshiba Satellite C655-S5305 application, running Windows 7. I made a few cds of music there are chandeliers and that they will not play on this computer. They do not play on my computer of husbands, good girls. I think that they are MP3. My cd drive is appearing and showing to work properly, but just read it as a blank CD. To go with this... I am a legal transcriptionist and use a program called FTR player. I downloaded some MP3 audio files and who won't play in my FTR player either, so I think it has something to do with. MP3 files, in the form of .wav files play in my FTR player very well. Any help would be greatly appreciated. Thank you in advance, Jodi
Red flag. CCcleaner. If you used to "clean" your registry database, which can cause problems. CCcleaner is also a good program, but registry cleaners do not help and remove what they think are "unused" entries in the registry that can cause problems later.
Try to download the Real Player and see if that corrects your problem, but if it is not, you may need to restore your computer to the factory settings by your user guide's instructions.
When you got your system back as you, I invite you to buy an external hard drive, and a good backup 3rd party program. You can configure it to automatically do everything in time and frequency of your choice. External hard drives 1 TB are about $85 these days and a very good FREE backup program corresponds to the Easeus todo backup free of charge that you can download from
http://www.todo-backup.com/products/home/free-backup-software.htm . Who can make you save a lot of time and frustration, the next time something like this happens. Sooner or later, it happens to all computers for one reason or another.
Good luck.

Is there a way to link to songs that are already in my ITunes library, so that they will always play together?
N ° not with iTunes. There are third party tools that can bring together two files, but you have them separated in iTunes, but considered as a unit.

Flex 2 network slows down the entire network
I bought a Flex 2 a few weeks ago. Installed the software Office 365 and creative cloud by Adobe. Everything worked well on both networks, I connect to.
Today, performance on the entire network is now gone to the dogs. At first, I suspected the provider or router so crossed all the routines of standard service (this disconnect, which reboot) again and again. Same face, deadly slow performance of several PC and Mac on the network.
Then, I hit on the idea to close my Lenovo. Suddenly, network download speed of 2 MB/s and the ping from 2000 MS to more normal speeds returned.
I restarted the Lenovo a couple of times, from 2, 4 GHz to 5 with the same result.
At some point when I plugged the Lenovo directly into the modem (part of the diagnosis) direct speed seemed faster.
Because the router works perfectly with all the other machines and I haven't changed a thing on it, and because the symptoms get carried away on the network when the Lenovo is cut, I can only assume that there is something to do with the Lenovo Flex 2 and how it communicates with the rest of the network.
I should also add that I tried to plug an ethernet cable to make sure that it wasn't just a wireless thing. Still had the slow performance.
I'm pulling my hair out over this, if I can't fix it, I can't work (no one in my office will be able to work) and will have to return the machine...
Any ideas?
Thank you...
Thanks for the reply.
After much pulling hair and analysis where the traffic was, it turns out it was a Microsoft cloud service a too aggressive drive that decided to download dozens of large files at the same time instead of in series. This excessive series of connections slowed down the rate of time and transfer of ping everything on the network. Disable updates for OneDrive during periods of work seems to have solved the problem.
That said, working on this, I see that updates from Lenovo is continually a significant overhead. Do not understand why it takes so resources...
Thanks again for the response...

I am creating georeferenced PDF maps using a mapping program, I have no problem to open the PDF with Adobe Reader / Acrobat. I use Adobe Acrobat to add annotations and comments to the map in PDF format, and I can still not display the annotations and comments when I re - open the file with Adobe Reader / Acrobat. However, when I try to open the file on Avenza, overhead rates disappear. Anyone know how I can save annotations and comments so that they appear when you open the file with all the Apps? This is perhaps a question that arises for the specific application in question - Avenza. Thanks for any input.
3rd party software may or may not support what Acrobat Reader on mobile devices. If the content does not appear, then your not likely Adobe software does not support this content. For example, many PDF viewers accept the forms. However, it is a question, you should ask your provider of software 3rd party.
HTH,

You ensure that you do not have a problem with a sticky key F1 on your keyboard?
Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the Add-ons is the cause of the problem (switch to the DEFAULT theme: Tools > Modules > themes).
- Makes no changes on the start safe mode window.
See:
- Troubleshoot extensions, themes, and issues of hardware acceleration to resolve common problems of Firefox
- Solve problems with plugins like Flash or Java to solve the common problems of Firefox
If this does not work in mode without failure, then disable all extensions and then try to find out who is the cause by allowing both the problem reappears.
- Choose "Disable all add-ons" on issues to troubleshoot Firefox in Safe Mode to set window to disable all extensions.
- Close and restart Firefox after each change through "file > exit ' (Mac: ' Firefox > leave";) Linux: "file > exit ')
If this does not help then try a new profile.

How do I set up my default BlackBerry for Wi - Fi connections, rather than the AT & T network, where a Wi - Fi connection is available?
Use of data stops when I move to another application? In other words, if the web page loads always when I move check text messages, or if the web page refreshes periodically. How does the data usage stops?
Your default BlackBerry automatically a Wi - Fi connection if such a connection is present and is strong enough. As long as your Wi - Fi connection is enabled, data will travel through it. The only way to ensure that no data continues to use the Wi - Fi is turn off once you have finished with it.
I hope this helps you.

If I export the Favorites to internet explore that they will remain in firefox?
I would like to export firefox bookmarks to internet explore without losing them in firefox.
No, you'll never lose bookmarks in Firefox if export you an HTML backup or to a JSON backup.
If you include an HTML backup then these bookmarks will be merged to the existing bookmarks.
Restoring a backup JSON in Firefox however will replace all existing bookmarks and you get a warning about it.
