MAC Addressess not showing on my new 3560 switch
I have a Cisco 3560 (Switch B) switch I just introduced into my network. The gigabit ports are trunked from another switch (Switch A) to a Cisco 6509 WS (Main Switch).

The trunk ports are working just fine. I have configured all necessary remote management with no issues. However, my access ports are not working. I have set them up exactly the same as the adjacent switch A and it works just fine, but the same configuration on the new switch has not been able to pull IP information. I have provided information as to how the switch access ports are configured on both Switch A (working) and Switch B (not working). I should note that I tried this with a Cisco 7940 phone and it got stuck on "configuring IP" then I tried it with my laptop and it pulled a 169 IP address. Both were direct connections into switch B. When I run a show mac-address-table, neither device shows up in the table. Only the gig port MACs. Any thoughts? Please let me know if you need any more information.

Hi Mike,
It looks like you're guiding me in the right direction. I did a "show port security interface fa0/2" on the new switch and nothing was out of the ordinary with the exception of the 0 MAC addresses learned. But then I did a "show spanning tree vlan 224" Here's what I found:
Switch A (existing switch):

Switch B (new switch):
Spanning tree instance(s) for vlan 224 does not exist.
So with this new information, and with my trunk configurations above, what did you mean by a disconnect on the trunk?

hi im new apple ,ac book pro user ..Bought a mac 3 weeks before my mac does not show serial number on screen .Also I am unable to sign in imessage n facetime it gives network error like though i can access web site n etc .! What can be this issue n how to solve it??
Hi,
If the machine is brand new I don't see why the serial Number is missing (it is entered on to a special chip at the factory)
However if the machine is a return and has been refurbished then the Logic/mother board may have been changed and someone forgot to put the info back to the new board.

My mac will not show images when on the internet?
My mac will not show images when on the internet? I think I have inadvertently changed some settings but nor sure which one.
I am going to assume you are using Safari here. If so then go to the Apple menu bar and hit Safari-> Preferences. Under the Apperance tab there is a check box that is called "Display images when the page opens". Check if that is unticked.

IMG Menu is not showing Financial accounting New in ECC 6.0
Hi
We have completed a technical upgrade from 4.7 to ECC 6.0 but IMG menu of ECC 6.0 is not showing financial accounting new.I believe financial accounting new is the integral part of ECC 6.0 and both the menu Financial accounting and financial accounting new should show.
If anybody has face this issue,Please respond
Regards
GauravHi Markus,
I do have access to u201CActivate New General Leader Accountingu201D but help of this node says below points:
The functions for new General Ledger Accounting become available.
In the SAP Reference IMG, the previous Financial Accounting menu is replaced by the Financial Accounting (New) menu. Under Financial Accounting Global Settings (New) and General Ledger (New), you can make the settings for New General Ledger Accounting.
You activate the tables of new General Ledger Accounting so that your posting data is written to them.
Caution:
If you already use classic General Ledger Accounting in your production system, you need to perform the migration of this data before you activate New General Ledger Accounting. Migration is only possible as part of a project. For more information, see the documentation in the SAP Library under Accounting -> Financial Accounting -> General Ledger Accounting (New) -> Tools -> Migration.
I guess this tab is use at the time of going for the functional upgrade which I believe a separate project. We only want to have that both the node u201Cfinancial accountingu201D and u201Cfinancial accounting newu201D should appear.
Please suggest if you have any idea or any person who had faced the same kind of problem in past.
Regards

Adobe Photoshop Elements 12 for Mac does not show up in Applications. Tutorial for editing from iPhoto shows selecting the Adobe software in Applications. Am I missing a step in registering product?
I answered my own question: There's a difference between "download' and "install." Hunt for "install" (1.5 hrs in my case) and line up your passwords, Adobe ID, etc, then install. Took 15 min. The right choice shows up in Applications. Now it's on to figuring out why photo selected for edit in iPhoto does not show up on screen in Elements.

Email images are not showing in my new iPad.
email images are not showing in my new iPad. This was not a problem initially, but just started. I use yahoo mail. Any thoughts?
This seems to be a problem with Yahoo! that started within the past few days. I am assuming that you are accessing your Yahoo! Mail through Safari. Until a fix is issued, you have two options -- (1) use the Mail app included in iOS, logging in with your Yahoo! account information or (2) when in Yahoo! Mail in Safari, click on your profile name/pic in the bottom left corner, choose Options, and then choose the last option, which displays your e-mail using the older classic version of Yahoo! Mail. It's not as pretty or easy to manuever around, but at least it shows the images in your e-mails, which is the most important thing. Both Apple and Yahoo! have been contacted about this issue, so hopefully a fix will be released soon.

Give it a few days. For some reason it take some time for a podcast to appear in the Search results after it's been approved and appeared in the Store.

Address book of my mac does not show all my contacts in iphone. What do i do??
Address book of my mac does not show all my contacts in iphone. What do i do??
iCloud, which replaced MobileMe, requires OS X Lion (10.7.5) or higher. You will need to upgrade to OS X Lion higher in order to set up iCloud on your Mac. First check to see if your system meets the system requirements to upgrade.
Lion system requirements are:
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Mountain Lion and Mavericks requirements are the same, as listed here: http://support.apple.com/kb/HT5842.
If you can run Mavericks, you can download a free upgrade from the Mac App Store. If your system can only run Lion, you can go here to purchase a redemption code to download it from the Mac App Store. If you prefer Mountain Lion for software compatibility reasons, you can go here to purchase a redemption code to download it from the Mac App Store.
After upgrading, you will find iCloud in System Preferences>iCloud on your Mac, and can set it up as explained here: http://www.apple.com/icloud/setup/mac.html.
Before upgrading, you may want to check the compatibility of your existing applications by checking here: http://roaringapps.com/apps:table. Also be aware that older PPC programs such as AppleWorks and Office 2004 for Mac will not run on OS X Lion or higher. -

Home Sharing: Multiple Users on 1 Mac do not show up unless logged in
I've set up home sharing on 4 Macs successfully, however one Mac has 3 users. Since they are all not logged in at the same time, all of their itunes libraries do not show up, only the one for the user who is logged in at that time. Any ideas on how to fix this?
Also, how do I get new purchases to automatically download to all the shared libraries? I can't seem to locate that.Doesn't work - ask Apple.
Sorry, but at the moment I have no good feelings for them. User friendly multi-user environments don't seem to very popular at Apple.

Music from iPod not showing up on new computer
I recently purchased a MacBook after using iTunes with an HP laptop. Once I hooked my iPod up to my new Mac, many songs that I downloaded from sources other than iTunes and from CDs I had burned onto my iPod did not show up in my new iTunes.
Also, any new music I purchase from iTunes, if I want to put them onto my iPod, iTunes tells me that I must erase all other files before adding my new purchases.
Ideally I would like to keep all of the existing music from my old iPod and have it transfered to my new iTunes library.
What do I do?!Start here:

New iPhone photos not showing up on new Photos app on iMac
In the past, when I took a photo on my iPhone, within moments it would show up on Aperture on my iMac in the iCloud tab. This is not happening on the new Photos app on my iMac using the latest OS.
In fact, there is not an "iCloud' stream area within the Photos app. Also, under iCloud system preferences, I have selected "iCloud Photo Library, My Photo Stream, and iCloud Photo Sharing."
Not sure what I'm doing wrong here.Same problem.
After USB is connected, iPhoto shows iPhone name with "(0)" photos.
Same whether iPhoto is open or closed before USB is connected.
Same whether iPhone is on or off when USB is connected.
Rebooting iPhone did not help.
Relaunching iPhoto did not help.
Rebooting Mac did not help.

Mac does not show startup volumes
Hello, I've got a problem with my MBP!
It's the latest model (Core i7) and I'm using it with an Intel X25-M G2 SSD (160GB).
On a third partition of the SSD, I installed Windows 7.
(a little gaming, a few win-only applications)
Booting Windows (or from CD/DVD) should be possible by holding down ALT.
This worked fine for years on my old devices - But this does not work with my new MBP! Holding ALT during startup ends with a grey screen showing nothing! Without ALT, my MBP boots OSX. In the System Preferences I can choose to reboot to Windows (or from a CD/DVD). This works without problems, Windows boots...
But why can't I select my bootdevice by starting with ALT down? Any Ideas?
And please don't tell me to install reFit! I'll never do so!
I'm asking because I'm a little afraid of what to do in the case of reinstalling OSX to a broken/empty Drive where I can't select my bootdevice from within the running OS...I definitely do not need to modify my Mac that way.
Selecting the startup-volume is possible without refit, or at least should be and works on many many Macs I know/own.
As long as a feature is provided by any "preinstalled Tool" I wont use 3rd party. If a feature is missing I write my own program - but I'm not going to write my own bootloader...
So why does my 2010 MBP have problems with showing startup volumes when booting with the "ALT"-Key?
