For deletion...

Interesting: The release note is deleted because the bug is in the "Closed" State, which means he is considered undesirable and documented behavior, but Cisco could not have intended to provide a fix.  I think that maybe that's a problem with the toolkit of bug that closed bugs (C) do not display the accompanying note.

With regard to the bug:

The problem occurs because of the fragmentation of memory happened when too that many VLANS are on a port trunk on a phone.

Here is the original version:

Symptom:

A switch of cat3524xl discover error allocation memory. After these errors the

the memory is released upward, but it is fragmenting. The following error message may be

Poster:

5 dec 15:51:31 PUTS: % SYS-2-MALLOCFAIL: 568 bytes memory allocation failed 0x192C20, pool processor, alignment 0

-Process = 'PLEASE queue manager', PW = 6, pid = 56

-Traceback = 1C6CA4 1 8798 24 192 192F70 193468 try '' 2718 8 27012 27173 C 271E08 CA 272218 272, 0 1E3B9C

Additional information:

The switch is connected to IP phones and are configured with dot1q trunks down to

IP phones. Also, the switch is configured with a number of VLANs. As a result,.

the switch must send spanning tree BPDUS for all the VLANS on each phone, which is not

effective.

Workaround solution:

Set up a list of VLANS allowed on all voice ports using the following command:

switchport trunk allowed vlan

{

Add list of VLAN

|

all the

|

with the exception list of VLAN

|

delete list of VLAN

}

The allowed VLAN list should include only those that are absolutely necessary on

This port, usually just the voice and data VLAN.

  • Malwarebytes - do I need anything else (security tips)

    Hello ladies and gentlemen, Apple Support Forums!

    I have a few questions about this great little Mac Mini on my desk. Coming from a Windows background, I have a bit of inherent paranoia that needs a bit of smoothing.

    I have read about the security of the Mac, on the defences of sandbox, Gatekeeper, never install suspicious applications etc. But I guess it's always better to have a scanner installed as well. Mac simplifies the sort to choose as my old Windows, Emsisoft Anti-Malware and Superantispyware programs do not provide versions of Mac.

    Malwarebytes is one of my classmates that comes with the Mac version. And howdy to how fast it scans. O_o compared to Windows 7 minutes 30 seconds.

    Norton was even crap in Windows and Avast, I have more confidence. Avira for Mac looks nice and simple.

    So my questions are the following:

    (1) do I need anything else besides that Malwarebytes and Avira? (And common sense, I got load of Windows security vulnerabilities...)

    (2) as I understand it, Windows malicious software may enter the Mac, but they are completely powerless to do anything, just hang out? Under no circumstances can they interfere with my Mac? So as long as I scan with Malwarebytes, all bad guys he finds are for Mac and trash from potential Windows that the rest is harmless anyway?

    Thank you for any assistance you can provide!

    No reason for Aviri or another anti-virus application.

  • Need help to find an adapter for a third-party monitor

    Hi all! I find myself in need of a little guidance, and I hope that someone out there will have a quick n easy for me...

    I have a Mid-2011 27 'iMac. which has two ports Thunderbolt It is taken with a Wacom tablet that I use constantly, and the other is made by an external hard drive to a solid state, which has a built-in cable to Thunderbolt (no way to hang it on a different port). I also have a 27 "HP monitor that is currently connected via an HDMI USB adapter.

    The problem is that the HP monitor is actual "jiggy" - the USB does not seem fast enough to deal with requests for the monitor. It is almost unusable. I know I should run it via a HDMI adapter Thunderbolt, but as I have already mentioned the two my Thunderbolt ports are already in use.

    Someone at - it ideas? I need sort of three to two ports Thunderbolt hooks, but I can't seem to find anything for less than $300 that would work. (I am illiterate when it comes to the different cables, adapters, ports, etc., so I hope someone can point me in the right direction by using short words... Most of the products that I travel through list specifications that me Chicane).

    The monitor has two HDMIs and a VGA port, and my iMac has a Firewire 800 port, if that helps at all...

    2011 iMac have only 1 Thunderbolt port and there is no such thing as a Mid-2011, you must have an iMac of year later, if it has 2 ports Thunderbolt. All the 27 "iMacs, from 2012 to 2015 the current have 2 ports Thunderbolt.

  • Need to install Java command line tool

    I get this error after the installation of the new OS sierra. Java is up to date. How can I fix it?  Thank you.

    The most likely cause is the program that wants to use Java's only request the use of Apple legacy Java 6. That the developers didn't like enough to have use Java the right way, you need to install Apple legacy Java 6 or uninstall the program that wants to use Java - likely produced Adobe or a Facebook video chat program.

    Download Java for OS X 2015-001

    Maybe it's that the program requires a JDK be installed instead the JRE from Java.com. So, if you download the SDK Java Oracle of Oracle's Web site, then you might try that if you have a recent version of Java. However, I don't think I've seen someone declare that as successful as the program who need Java so poorly designed.

  • Sierra is a bomb, need help to return to El Capitan

    Could someone more at Apple just try it once to make sure that the "new and improved" operating systems actually work before releasing? With all the money goes to Cupertino, there is no money to hire testers rather than rely on Mac users? Talk about Stockholm syndrome. I'll cut to the Chase, now my computer has been upgraded to Sierra without my knowledge, and several apps are now, not to mention that I can't access my company's server today. How to return to El Capitan - can I save all my work from today and use Time Machine to restore my machine? If this isn't the case, should I really erase everything and start from scratch? Someone please stop me to jump on a ledge, I have work I need to pass on to customers. Any suggestions, help, you can give would be appreciated. Carl

    Restore your backup, and if you do not upgrade your Mac, who did? Maybe you should tell them not to do the without you knowledge or approval.

    Hello

    I see the message on my Iphone 5 s(IOS10-Updadte) camera-"The Iphone needs to cool down before using the flash"

    Please help me solve the problem.

    Hi sangani53,

    Thank you for using communities Support from Apple!

    This message indicating that your iPhone must cool before using the flash indicates that the temperature of your iPhone is passed to where certain features will be disabled.  Once you bring the temperature down, the features should come back.  Take a look at this link for more information on updating your iPhone in the operating temperature.

    Keep the iPhone, iPad and iPod touch in acceptable operating temperatures

    Take care.

  • Open photo of Photos in the Preview app? Need info GPS and maps!

    Hello!

    I write trip review and to see where my photo was taken (in the maps application), and what is digital gps coordinates for each image.

    Search on google - go, I got that via this pic of opening in 'Preview' app.

    But - I have all my pic in Photos app (automatically imported from my iphone to macbook pro Mac OS sierra).

    so, I can export all the photos, I need, in a specific folder and then, from there, open it in the finder and get my info, of course - but looks silly, I think.

    as I already have this pich in Photos - photo can I somehow open directly from Photos Preview app?

    or obtain the gps position open, where this picture is taken in cards programm (not this small window, which is in the Photos, but wide, Maps application) / and obtain the coordinates of the gps directly via the Photos app?

    Thanks in advance.

    Use the media browser in preview - in the open window on the left down - media = == > photos == > Photos

    or even more appropriate is to buy external editors for extension of Photos in the App store ($0.99) and you can view the pictures in preview when using the hotos
