Troubleshooting Multilink Group (Serial)
Hi,
I have been asked to look at a colleague's problem and I haven't touched multilink in a while, so when I looked at the initial output form various 'show' commands I think there still might be an issue. He has indicated that everything is working fine now but I have attached the output of the show command after this had been mentioned. With one of the serial interfaces as 'Down Down' and also showing as one member link as 'active' and one as 'inactive'. Any pointers would be appreciated, as I cannot help but think that only one circuit is working.
Attached is the sh int for both serial interfaces, multilink interface and sh ppp multilink. Also attached is the config for the router.
Thanks in advance.
I agree that you seem to have a problem.
(BTW, There is something that does not quite add up in the listings, because your show run show both serial links in shutdown.)
Nevertheless, the most useful output would be to do a debug ppp multilink and debug ppp negotiation, and then bounce the interface that is not joining the bundle correctly, and see what comes out.
Also, if you shut down 0/2/1 and try and bounce 0/2/0, does 0/2/0 then join the multilink bundle OK?

Hi Guys,
i got a situation here and hope someone will be able to help me out. Recently i configured a PPP multilink and am facing some issues after that.
Issue 1:
There seems to be lot of input error on multilink interface (150 errors in 40 mins)
Issue 2:
when any of the multilink member interface goes down (all other links are active), am getting packrt drops and request timed out when i ping my other end multi link interface atleast for some 30 sec , after which my response is ok.

Everytime I add the 'ppp multilink' to the serial, I get the virtual-access interface bouncing up and down with no traffic flowing.
any ideas?Cannnnnnnnt see much wrong, try adding "ppp multilink group 1" to int S0 config.

A multilink group having only one serial line as amember is configured on RouterA and similar on RouterB. Both routers hace PRI lines as backup having loopback address. OSPF is running on these multilink interfaces and it forms neighbor relationship with each other. So far it seems ok. As a backup to this multilink interface ( serial interface ) can one of the channel from PRI be configured to dial other router and also form a neighbor relationship.
Fro example :
RouterA and RouterB are neighbors on multilink interface. and using their loopbackl address. If serial link fails can RouterA diales to RouterB on PRI line and forms the neighbor relationship. Loopback address is already published in ospf process.
Thanks in advance
Any link on Cisco.combapat
I see no reason why you could not have a channel from the PRI establish a connection. If you are interested in that I think you should consider using the OSPF demand-circuit feature on the dialer. This link should give you information to get started with that:

i used time machine to reinstall all products on a new imac machine. everything seems to be installed but when i open aperture it asks for my serial # and when i put it in it says that is your upgrade serial.. we want the original serial #. that box is long gone, how do i find that serial #
If you cannot find your original serial number, you will have to contact Apple with a proof of purchase, see these links:

Aperture asks for original serial number after migration to new MAC
After migrating my software and files from my iMac to a new Mac Mini. Aperture asks for serial number first time I wanted to use it. Will not accept the serial number from either my first, Aperture 2 version of my Aperture 3 upgrade. I believe I never had version 1 - can't find amongst my software collection. Website support doesn't seem to allow me to display the software dtails I have registered with Apple over the years. How can I get this information?
Try Troubleshooting Professional Application Serial Numbers and if that doesn't help see Pro Application Replacement Serial Numbers
Apple support has been pretty good in the past suplying new serial numbers with the bare minimun of documentation.
good luck
Message was edited by: Frank Caggiano - reading your post it is not clear but if this version of 3 is an upgrade from 2 you will need both serial numbers. First enter the serial number from version 2 then the number from 3

HT4007 Aperture 3 serial number
I've just reset my macbook pro and installed mountain lion, I have copy of aperture 2 and an upgrade serial number for 3, neither work, aperture 2 won't open at all with mountain lion, and installing aperture 3 won't let me use the upgrade serial number, can anyone help?
On what media is your copy of Aperture 3?
Have you seen Troubleshooting Professional Application Serial Numbers
Basically you will not need to install your version of 2, install 3 and enter both the original serial number from 2 and then the update serial number from 3. -
Hi...
In my report i used serial no but it is now coming 1 2 3 like this it showing 1 4 6 like this.
may i know what is the reason behind that please help meHi There
Thanks for your posting.
Please try this. Open the report properties (right click on blank area outside the layout and click properties) or (Menu-->Report-->Report Properties)
Click on the code pane on the left
In the code window enter below script
dim Counter as integer=0
Public function getCounter() as Integer
Counter=Counter+1
return Counter
end function
dim Counter as integer=0
Public function getCounter() as Integer
Counter=Counter+1
return Counter
end function
Go to the properties of the group (based on which group you need the group serial number)
Click the variables tab on the left
Click on Add and set Name as GroupCountValue and set the expression (in the expression window) as
=Code.getCounter, click ok and close the window.
Now in the textbox where you want to display the Serial number, set the expression as
=Variables!GroupCountValue.Value
Run the report and observe the result
I hope this will help
If you have any question please do ask
Many thanks

Serial number doesn't work on new iMac
I've transferred my verisonof Aperture to my new iMac. The software prmotps me for my serial number, but when I enter it, it tells me the 'serial number is not valid'.
Does this mean I have to buy the software again?Have a look at this support article:
Troubleshooting Professional Application Serial Numbers: http://support.apple.com/kb/TS2005
If you cannot get Aperture to accept your registration code that way, try Frank Caggiano's trick:
Why does Aperture "lose" registration info?
https://discussions.apple.com/message/17016704#17016704
And if all fails, convince Apple to senda new Registration code:

I previously bought Aperture 3 and installed in on an iMac and a MBP. I just bought a new MBA to replace the MBP, but the MBA doesn't have enough memory for me to do a complete restore of the MBP on the MBA. So I am trying to find a way to deactivate the serial code or Aperture 3 on the MBP so I can reinstall Aperture 3 on the MBA. I have been searching forums and google and I have not been any answers. Any help would be appreciated. Thanks.
How did you buy Aperture? Did you buy it from the App Store? Then you can download it again on your MBA, if you sign into the App Store.
If you bought Aperture buy buying a licence key to unlock the trial, try if this download link for the trial version still works: if yes, you can unlock it with your serial number:
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/Aperture/061-8328 .20101020.AprE3/ApertureTrial3.1.dmg
And if you own the boxed DVD installer , use the DVD to install Aperture on your MBA. If the installer does not work - and you get the message
"check with the developer to make sure Aperture works with this version of Mac OS X"
you may have a problem with an expired developer certificate (they expired mid march).
To fix this, set the Date in " SystemPreferences -> Date&Time" to a date well before March 2012 and run the Installer again. If that succeeds and Aperture now runs, reset the date to the current date.
You can see your serial number in the "About" panel in the main Aperture menu bar on your MBP:
Aperture > About Aperture.
For the "invaldid serial number" see these links: You may have read the letters incorrectly - some are look alike, "1" or "I", "0" or "O"; your shift-lock key may be set.

Aperture serial number does not work
I just got a Mac Book Air, my Aperture Serial number does not work. it tells me it is not correct. How can I use my software now?
First how did you purchase Aperture and how did you install it on the Air? As the Air does not have a DVD drive it would help to know how you got the app onto it.
Start with Troubleshooting Professional Application Serial Numbers and see if that helps.
There is also Pro Application Replacement Serial Numbers if you're not able to get your serial number working. -
Aperture not recognizing serial number
I went to the Apple Genius bar for help today and they wiped everything off and restored my OS. I am now trying to put the Aperture software on that I bought 2 years ago, and it's saying the serial number is not valid. What do I do?
ThanksThere has just an update been released, Aperture 3.4.3, that is supposed to fix serial number issues, try if updating helps.
Is your Aperture version an upgrade from Aperture 2? Then you need to enter both serial numbers.
And checck the correct typing - sometimes letters can be confused, the letters in the serial numbers are all upper case, see Troubleshooting Professional Application Serial Numbers and see if that helps.
If all fails, contact Apple for an
Pro Application Replacement Serial Numbers . You will need to provide a proof of purchase.

Aperture won't accept my serial number
I transferred to my new Mac using Migration assistant but when I went to start Aperture 3.3.2 it asked for my serial number. I purchased it on disc as Aperture 2.0 and bought the 3.0 updater, also on disc. It won't accept either of my serial numbers. Obviously I have tripple checked that I am tuyping them in correctly. Any ideas what is going wrong and how to solver it?
Maybe you have an old ProAppsSystemID file:
Quit Aperture, log off and log on again.
Then switch to the Finder and open your System Library and navigate to the folder:
/Library/Application Support/ProApps
Look, If there is a file "ProAppsSystemID" and move this file to the desktop, and also any other files with Aperture in the filename.
These support articles may help:

New iMac won't recognize Aperture 3 Serial number?
Hello
I am trying to load aperture 3 on my new imac. When I enter the serial number it gives me the message "You have entered an upgrade serial number. Please enter your original serial number". What I am entering is the original serial number that came with aperture 3. A couple of things that maybe important to note is that I have used both aperture 1 &2 prior to installing aperture 3. As well, I am currently running aperture 3 on two additional machines which I will be slowly fazing out.
Any suggestions would be appreciated.
Thanks, ShaneThe key question is, is the Aperture 3 that you bought an upgrade version or full version? And how and when did you buy it, Apple online store, DVD or App Store?
If it is an upgrade version you will need to enter you're Aperture 2 serial number. If it is a full version then have a look at Troubleshooting Professional Application Serial Numbers and Pro Application Replacement Serial Numbers
Finally you can try going to /Library/Application Support/ProApps and seeing if there are any files there with Aperture in their name in some form. Post back if there is.
