VPC trouble - link flapping between C3750 stack and Nexus 5596

Hi All,
I have configured 1 vPC's between 2 Nexus 5596 and 1 stack C3750 switch. The links in the stack are distributed over both members.
Gi1/1/1 -> Eth 1/44 NX 5596-02
Gi 2/1/1 -> Eth 1/45 NX 5596-02
Gi 1/1/2 -> Eth 1/46 NX 5596-01
Gi 2/1/2 -> Eth 1/47 NX 5596-01
The same logic is for another stack C3750 to the same pair of Nexus 5596 switches.
The problem is that the links from the vPCs keep flapping at random moments - 1-2 times per hour.
The network is not loaded at this time and the same issue is on both vPC's.
the flaps in the nexus 5596 looks like this
%ETH_PORT_CHANNEL-5-PORT_DOWN: port-channel108: Ethernet1/44 is down
%ETH_PORT_CHANNEL-5-FOP_CHANGED: port-channel108: first operational port changed from Ethernet1/44 to Ethernet1/45
%ETHPORT-5-IF_DOWN_INITIALIZING: Interface Ethernet1/44 is down (Initializing)
%ETH_PORT_CHANNEL-5-PORT_UP: port-channel108: Ethernet1/44 is up
%ETHPORT-5-IF_UP: Interface Ethernet1/44 is up in mode trunk
On the stack is just up/down the pair interface.
I started few debugs on the stack and captured the folowing output:
C3750X-02#im_if_stack_relationship_add: Posting the ACP job for stack add for 5018.10902

Do someone have any idea what happens here ?
The configuration is ok because i have another vPC connected to FEX's and is working fine.
Kind regards,

Hello,
Problem solved after upgrade to the last version of NX OS 6.0.2.N2.3

You need to trace this mac address: - 00ab.cdef.0123 and check if this has dual nic card if yes then check if nic teaming is configured correctly ...then shut down one of the link and see if you are learning the same mac address on two different ports?

(Trouble printing) Trouble with connection between Macbook Pro and Hp Deskjet 1510.

Trouble with connection between Macbook Pro and Hp Deskjet 1510. (Nothing Prints).
I have a Macbook Pro and am having difficulty printing documents from ‘Pages' from my Hp Deskjet 1510. I have installed the necessary software for the printer and it is connected via USB. Every time I try to print the printer icon comes up as it should, 'printing' and then 'job completed' and then the icon disappears. (Nothing is printed.) I thought it might be something to do with Pages compatibility with the printer but exporting the document to Word or making it a PDF doesn’t change anything. I don’t have Microsoft Word on my computer. The scanner does work and when I printed a ‘Test Page’ that worked too.
Let me know if you know why this is happening.

With these settings the network now works flawlessly, however, when i have my ethernet cable plugged in, my internet access via my airport card(on the macbook pro) is no longer available. Hoping you can tell me why this would be with this info i've provided.
Educated guess. The networking devices have priorities as to which are used. The standard order is that Ethernet has a higher priority than Airport.
While your Ethernet is unplugged it is inactive and the Mac ignores it. Once you plug it in, the Mac sees that it is active and switches traffic to that interface.
I actually take advantage of this feature at home, but configuring my Airport and Ethernet with identical fixed IP addresses. Normally I'll use Airport, but if I'm copying a huge file and I want faster performance, I'll just walk my MacBook (previously iBook, previously Powerbook) over to my Ethernet switch and plug in my MacBook. Magically, the Mac detects that the Ethernet is active and continues the file transfer uninterrupted over the faster 100baseT Ethernet connection. When the transfer is finished, or if I really need to move back to the Comfy Chair, I unplug the Ethernet cable, and all activity reverts back to the Airport, all without disrupting any existing networking connections.
You on the other hand have totally different settings for your Ethernet and your Airport, so when you switch to Ethernet, you basically loose your Airport connections.
Something you can try:
System Preferences -> Network
Gear icon on the bottom left, next to the [+] [-] icons.
Select *Set Service Order...*
Now Drag the network interfaces into the perfer priority order you want. In this case put Airport above Ethernet.
NOTE: You may want to create a new Network Location for this, instead of messing with your normal home Location (which is most likely the default Automatic. That way you have your original you can always fall back to.

BP change documents ( linking problem between Object id and Business Partner)

Hi,
We need to create a report for documents changed for a Business partner.
This will be done in sap bw.
on source side I have created the datasource with function module changedocument_read and I am getting most of the information
which I want. Only missing part is Business Partner number.
Can somebody suggest , how I would be able to link Object Id to business partner.
I need to pull everything that is changed at BP level and the Object class selection around 30 in number.
So I am looking for any standard function module which can provide me the link between Object id and Business partner.
If I establish the rules to determine the Business partner from Object id , its getting bit difficult.
Can somebody please help/suggest.
I have gone through many documents and scn posts but unable to find anything on this.
Thanks !

Hi, looking at the change history header table CDHDR it seems that object ID simple equals the internal format of the business partner number.

Etherchannel issue between 3750 stack and WS-CBS3012 for IBM blade centre

Hi,
We are trying to configure Etherchannel between four ports of cisco 3750 stack(2ports from one switch of stack and two ports from another switch of same stack). We are facing issues with this setup. The ports in WS-CBS3012 are going to err disable mode.
Is there any limitations associated with such a cross-stack etherchannel configuration. Please suggest if there is any particular sequence of configuration involved.
Switch1 in stack
int gi 3/0/3
switchport mo trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
switch 2 in stack
int gi 3/0/3
switchport mode trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
int port-channel 1
switchport mode trunk
switchport trunk allowed vlan 10-30
sw tr en dot1q
channel-group 1 mode on
spanning-tree guard root
in WS-CBS3012 ports are configured with trunk,allowed vlan and etherchannel configuration with mode on.
With Regards,
Madhan kumar G

Hi,
The commnad "no spanning-tree etherchannel guard misconfig" on WS-CBS3012 resolved the issue.

Link table between AP Invoice and AP Downpayment Invoice

Hi,
I want to get the link between the table OPCH and ODPO,
so that I can monitor the cash advances,
Thank you very much,
Regards,
Clint

Hi Gordon,
I have tried that already, if we follow the process, First we enter the Downpayment from AP Down module, after that we go to the AP Invoice and we click the button Total Down Payment to call the amount from Downpayment, we cant see the Base Entry and Target entry since both have different module but we can see they must have be a connection since Ap Invoice can call the payment from Downpayment and there must be a connection between them but I cant see how.
Thank you very much.

Trouble syncing Calendars between iOS 5 and Snow Leopard

I updated my iPhone and iPad to iOS5 and the iCloud stuff seems to work great between them.
However, my Macbook is running Snow Leopard and I am unable to sync my calendars onto it from my iPhone or iPad.
Syncing my calendars with the Mac over iCloud would be ideal, but even the wired connection doesn't seem to sync the calendar anymore, as it always did.
Any suggestions how to fix this?

Do the referenced links on this tip: https://discussions.apple.com/docs/DOC-2551 say that calendar syncing is even possible with Snow Leopard? If not, you may wish to switch to another webhost such as those found on http://www.comparewebhosts.com/ if upgrading to Lion or installing Windows is not an option.

Load data with SQL Loader link field between CSV file and Control File

Hi all,
in a SQL Loader control file, how do you specify link with field in CSV file and Control file?
E.g. if I wat to import the record in table TEST (col1, col2, col3) with data in csv file BUT in different position. How to do this?
FILE CSV (with variable position):
test1;prova;pippo;Ferrari;
xx;yy;hello;by;
In the table TEST i want that col1 = 'prova' (xx),
col2 = 'Ferrari' (yy)
col3 = default N
the others data in CSV file are ignored.
so:
load data
infile 'TEST.CSV'
into table TEST
fields terminated by ';'
col1 ?????,
col2 ?????,
col3 CONSTANT "N"
Thanks,
Attilio

With '?' mark i mean " How i can link this COL1 with column in csv file ? "

Link Chart between New Listing and Custom OrgChart

Hello,
I created a new Listing and a Custom Org Chart. They're works fine.
When I'm editing my Listing in General Settings -> Link Configuration, I marked View In OrgChart and selected my custom orgchart.
So, when i login as user in OrgCHart, in My new Listing, I search for a Object and in Actions section I can see only Profile Option.
I can't See View In OrgChart.
What i forgot to do?
Thanks Again.

Hi João,
Sometimes this doesn't work - you need to edit the linkconfiguration that is named after your custom orgchart/search details panel(s). Without seeing the file I wouldn't know what to change, so if you can paste it here that will be helpful.
Best regards,
Luke

Differences between dual stack and single stack Java system copies

Hi
Can any body please provide step - by -step procedure.
Thanks in advance
Edited by: Kobby bryant on Apr 13, 2008 10:39 PM

Hello Koby,
Dual stack is ABAP+Java instance.
Single stack or Standalone is just Java instance. There is no ABAP part.
Using the installation wizard, you could select the desired option and the installation is performed accordingly.
If you are looking for any specific info, please provide the details.

Linking field between purchase order and inbound delivery

Hi
I have to enter some data in the purchase order and it has to automatically updated in the inbound delivery.
For eg: if we enter bill of ladding number in purchase order, it has to get automatically populated in inbound delivery.
Regards
shaker

Hi,
Is the example provided by you, just for example purpose or is that the field you want to copy? If that is the field you want to copy from PO to Inbound document, then how would you know the BoL no. / details at the time of PO creation?
However if it is just an example & you want to copy some other field, then you might want to evaluate the below exits:
MM06E001 User exits for EDI inbound and outbound purchasing documents
LMELA010 Inbound shipping notification: Transfer item data from IDOC
Check with your abaper.

Vivek

Can anybody help please?

Hopefully, one of these two suggestions will get it back.
Either quit iTunes and launch it again or restart the entire computer. It's amazing how many times a simple restart can solve a problem. Hopefully it does for you.
