MPLS P and PE physical connectivity

Hi all,
I have a question regarding the physical connectivity between a P router and a PE router. Some are saying it's best practice to use two 2960G, but I am not convince. Why not connect both P and PE directly? That would probably be more efficient as well.
Thanks
Martin

Hi Martin,
The connectivity between PE and P in a MPLS environment largely does not depend on MPLS features but on other network design considerations like bandwidth, available cabling, intermediate equipment required, f.e. POS or ethernet, distance between P and PE - to name just a few. It is perfectly OK to have PE and P connected back-to-back.
There are many networks in service provider or enterprise environments, where exactly this is implemented in parts of the network. There are even large MPLS networks without any 2960G interconnecting PE and P routers.
Your information about the usage of 2960G might stem from another requirement; for the MPLS P or PE functionality it would not make a difference. So I would not call it best practice without specifying in more detail, which other requirements lead to this statement.
Hope this helps! please rate all posts.
Regards, Martin

Double backup two MacBook Pros each physically connected to their own external disks?

We have two MacBook Pros 17" (an early 2008 and a late 2011) connected by WiFi, both running OSX 10.9.3 and each physically connected to their own My Book external disks. After I started the first MacBook Pro's backup to add the second MacBook Pro's external disk, I couldn't set up the second MacBook Pro's backup to add the first MacBook Pro's external disk. Each of these My Book external disks had previously been used for backing up each MacBook Pros. None of the help pages helped.

On the computer to which the drives are connect enable File Sharing via Sharing preferences. Select the drives you want shared and CTRL- or RIGHT-click then select Get Info from the contextual menu. In the upper pane is a checkbox labeled "Shared." Check the box to enable sharing the device.
On the other computer select Connect to Server from the Finder's Go menu. Click on the Browse button to locate the shared computer. Double-click on the icon which should bring up a login dialog. Log into the admin account of the shared computer using the Registered User button. You will then be prompted for the admin password of the account. Enter it and click on the OK button. This should connect you and provide access to the shared computer and devices connected to it that have been marked as shared.
For more help select Mac Help from the Finder's Help menu and search for "file sharing."

Physical Connectivity from Fabric Interconnect to MDS and Failover please suggest

Dear Team
We have 2 FI and 2 MDS 1 SAN
Currenlty the connectivity is
2 direct physical connections from FI-A to MDS1
2 direct physical Connections from FI-B to MDS2
From MDS 1 connection to SAN Primary controller
From MDS 1 connection to SAN Secondary controller
From MDS 2 connection to SAN primary controller
From MDS 2 connection to SAN Secondary controller
Hope the above connectivty is fine?
we had looked at
http://www.cisco.com/en/US/prod/collateral/ps4159/ps6409/ps5990/white_paper_c11_586100.html (as team always preferred to go via cisco standards)
In FI we have to cluster the FI and Primary and Subordinate,likewise here for MDS to we need to? or will it be done via FIs ?
If not these 2 MDs they work independent but sharing the configs that happens among them?
Now what ever changes (Zone Creation)we make on MDS1 hope that will get relpicated to MDS2 via FIs?
If MDS1 Fails will all the configuration be available on MDS2 and still the infra will be smooth running ? and vice versa?
Any additional steps to be done to achieve it?
Which is the best way to achieve it please suggest
Thanks and Regards
Jose

Hi Jose.
Physically your connectivity is good.
On the UCS side, the 'Primary' and 'Subordinate' role refer only to the Management of the system and which device is actually running UCS Manager.
Each MDS device will have separate configuration (zoning). It's different between the 2 devices.
The blade itself will have a connection out each side, or 'SAN Fabric'.
e.g.
           +----+
       +---+    +-----+
       |   |    |     |
       |   |    |     |
       |   |SAN |     |
       | +->----<--+ |
       | |         | |
       | |         | |
   +---+-+-+    +--+--+--+
   |       |    |        |
   |MDS-A |    |MDS-B   |
   +--^-^--+    +---^-^--+
      | |           | |
   +--+-+--+    +---+-+--+
   |       |    |        |
   |UCS-A |    | UCS-B |
   +--+----+    +-----+--+
      |               |
      |               |
VSAN100    +-----+    | VSAN200
      |    |     |    |
      +---->     <----+
           |Blade|
           +-----+
The blade will have a HBA on FabricA (VSAN100) and FabricB (VSAN200)
Each HBA will have a different WWPN, and on the SAN array, each controller will have a WWPN
So on MDS-A, the zoning will be:
Blade WWPN A
Storage WWPN Primary A
Storage WWPN Secondary A
MDS-B, the zoning will be:
Blade WWPN B
Storage WWPN Primary B
Storage WWPN Secondary B
So the configuration is *not* synced between the two MDS devices, but they each have visibility to the blades vHBA device. At the blade level, the Multipathing software on the Operating System will handle any failover.
On the UCS, we would generally use a Port Channel up to the MDS.

I have two location one is Delhi(IP-192.168.100.*) and another is Mumbai(IP-192.168.1.*) and both are connected by MPLS line and ping with each other. We have one DC in Delhi location and domain name is CAPLDC and Delhi location all PC is member of this

I have two location one is Delhi(IP-192.168.100.*) and another is Mumbai(IP-192.168.1.*) and both are connected by MPLS line and ping with each other.
We have one DC in Delhi location and domain name is CAPLDC and Delhi location all PC is member of this domain and working properly.
now i am trying join the Mumbai location PC with my Domain(CAPLDC) but they are not join with my DC and generate the error.
I have chek the DNS and nslookup all are correct but this is generate error.
Is this possible Mumbai location join with this Domain(CAPLDC)???
One more thing when i have created another DC with this name (papldc.com) then Mumbai location is joined properly.

Why are you using a single labeled domain? I would recommend renaming the domain name to be something like domain.com.

How do I physically connect the SCXI 1180 when using a 1520 and 1346 adapter?

Here's my current configuration:
SCXI 1000 chassis
x2 SCXI 1520 Bridge Modules (Slot 1, and Slot 2)
1180 Feedthrough panel.
I recently purchased a 1346 adapter so I can use the feedthrough to access AI channels on the DAQ card.
My question is, how do I physically connect the ribbon cable of the 1180? Does it plug into the BACK of the last module in the chassis (ie. bridge module2 in slot 2) or does it plug into the other 49pin connector on the 1346 adapter?
If you read the installation manual for the 1180 http://www.ni.com/pdf/manuals/371062a.pdf (Page 2-3)
And the installation manual for the 1346 http://www.ni.com/pdf/manuals/320722b.pdf (page 2)
it seems the instruction contradict eachother. The 1180 manual says connect it to the back of the module
the note under Fig.2 on page 2 of the 1346 says you cannot have anything plugged into the module next to the one that has the 1346 plugged into it; in my case that's module 2...
SCXI- 1000 Chassis w/ 1346 adapter
PCI 6281 DAQ card
SCXI- 1520 Bridge Board w/ 1314 Terminal Block (x2)
SCXI- 1180 Feedthrough Panel w/ 1302 Block
Signal Express 2014.
Win7 Enterprise

I have the 1346 plugged into the first module in slot 1.
But let me try and clairfy what you're saying...
"Then the cable from the 1346 kind of loops back into the chassis and through the 1180". So this is my answer? But I'm actually taking the cable from the 1180 and plugging it into the other 49-pin connector on the 1346. Sorry, symantics...
"...it must be on the first card when using a 1520". By "it" are you referring to the 1346 (which is how it's currently configured) or the 1180 cable?
and lastly; why does the 1180 need to go into slot 2? I can currently fill both slots (1&2) with the 1520's and with the 1346 plugged into module1/slot1, I can pass the ribbon cable around back of module2 and into the 1346.
Is there some other reason beside potential space limitations that you'd use the feedthrough in slot2?
Thanks for your info and patience!

Deploying and testing an app without physical connect

Hello,
under https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistrib utionGuide/TestingYouriOSApp/TestingYouriOSApp.html
there is a chapter:
Installing Your App on Test Devices
Before you distribute your app to testers, follow the steps that testers use to install and run the app on their devices. Use iTunes to install the app on a nondevelopment device. iOS extracts the embedded ad hoc provisioning profile in your app and installs it on the device for you. Then test your app on the device.
Follow these steps to install the app on a testing device.
Finally, send the iOS App Store Package file to testers......
Is it possible testing and deploying an app without physical connection to a computer (security risk etc.)?
An example: Upload the app-file to a developer-environment in the app-store and then download to the iPhone.
Thanks and greets
Oliver

Ok I figured this one out with help form Kapil (thanks Kapil).
Here are a few lines of code that is needed:
<s:HTTPService id="myPersonalInfo" fault="faultHandler(event) resultFormat="e4x" result"personalInfo(event)"/>
Then create a function e.g.
private function requestPersonalInfo():void{
domainUrl="your url.com";
personalInfoRequest="";
personalInfoRequest=domainUrl+api_xml_string;
personalInfoRequest+="common-info";
myPersonalInfo.url=personalInfoRequest;
myPersonalInfo.send();
private funtion personalInfo(event:ResultEvent):void{
personalName=event.result.common.user.name;
Username.text="Welcome" + personalName;
Thats it.

MPLS Handling of Aggregated ADSL-connected sites

I'm familiar with serially-connected sites entering an MPLS core, where there is a physical connection associated with each site, and so the site is simply identifiable to the MPLS PE by virtue of a physical port. However, I'm trying to get my head round how to handle ADSL connections, where many sites' traffic is aggregated into one bearer. How does the MPLS network associate the right traffic with the right site under these conditions? Sorry if this is a bit of a "dumb newbie" question, but I've googled extensively, and just haven't got to the stage where I feel confident in my understanding.
Jim

Hi Jim,
When using DSL most architectures use PPPoA/PPPoE (you could just bridge at the dslam and use no PPP but that would result in a subinterface a VRF could be configured on).
PPP will create a virtual-access interface per PPP authentication (username).
When the virtual interface is being created the provider router (LNS) will ask a radius server if the user can be granted access. If yes, the radius can also give the router configuration information which can include IP address and VRF.
Ultimately the traffic is kept separate because point to point logical sessions can be built on top of a multi access network (PPPoE).
Hope this helps,
Matt Ayre

HP LaserJet Pro MFP M127fn and Remote Desktop Connection

So, my pc operates on Win7-64bit. I use Remote Desktop Connection to log in to the company server, running on MS Server 2008. I purchased the HP MFP M127fn today after confirming that it is compatible with both OS listed above. I successfully installed it directly to the server via usb cord - to make sure the correct drivers downloaded to the server. I was able to test-print and print from an app while physically connected to the server. I then disconnected the printer from the server and successfully connected it to my local pc. I can test-print and print from an app on my desktop. When connect to the server via RDC, it recognizes the MFP M127fn as my default printer, and sends a print job to my local pc. I can see the job in the server print queue, I can see the print job in queue on my desktop....it spools, then says it prints, however no actual print job ever materializes.
If I select to print to the MFP M127fn fax from the server, it will open the fax window on my desktop, allow me to enter a phone number, and will dial out and send the fax. So, that driver is functioning properly.
So, my question is this: If the printer and fax claim to be successfully installed, why do I not get the print job that is sent via the server and appears in my local print queue? I get no error, either on the server side or the local desktop. They both truly think the job has printed.....but no paper ever comes out.
Our company has used several other HP printers over the years with this same set-up and have never had a problem until now. The last one was also an HP MFP - the CM1312. So, I am now completely stumped by this. I called HP support and was routed through 4 different areas before I was told that no one had a clue what the problem might be. I then called the Easy-Tech desk at Staples, where I bought the printer, and was told that it was most-likely a hardware issue and I should return the printer to swap it out for another one. If nothing would print at all, I would agree it's hardware. But, as I can print locally, I'm more-inclined to think it's driver-related......any suggestions?

Hi,
The M127fn uses the PCLmS printing language which is a lightweight printing language, a such is not supported for RDP printing.
As a reference you may find the following socument about Citrix, Terminal Services and RDP Printing, as you may find listed the M127 is not supported for a such:
http://h20195.www2.hp.com/v2/GetDocument.aspx?docname=4aa0-8465enw&404m=secure-erc
That is clearly not an harware issue, however I suggest returning the printer and replacing it with a different model which better feet such a task.
The M225dn as an example uses a PCL 6 print driver and should provide a better feet for RDP printing using HP UPD.

Can i use my time capsule to extend my wifi signal without physically connecting it to my router?

I currently have a BT Homehub connected to a modem, which is connected to the ethernet port in my wall (which is downstairs). I bought a timecapsule to wirelessly back up my computer. It is connected via ethernet cable to my router. I have recently been having trouble getting a wifi signal in one room in my house (upstairs). To fix this i was wondering whether it is possible to move my time machine somewhere upstairs, to a location closer to this room, and have it transmit a wifi signal without it being connected to my router via ethernet. And if so how would i go about doing this?
cheers

Can i use my time capsule to extend my wifi signal without physically connecting it to my router?
Yes, if you have an Apple router.
No, if you have a BT router.
IF....your Time Capsule is currently set up to provide a wireless network signal, you could add another Apple device...like an AirPort Express....to extend the Time Capsule wireless signal.

When deploy: Wizard error a connection to the deployment share could not be made "check physical connection"

Hello everybody,
yet another issue with deploying a masterdisk. I will give you a short explanation of the situation.
I need to deploy Windows 8.1 PRO x86.
Using: Microsoft Deployment Workbench Microsoft Version: 6.2.5019.0
1. Reference PC: Windows 8.1 PRO x86 is installed on ORACLE Virtual Box.
2. I installed MDT on my workstation Windows 7 x64, where "C:\DeploymentShare\Windows8" is located.
3. To change the Unattended.xml file, I have second ORACLE Virtual Box with
Windows 8.1 PRO x86 with MDT, which connected to the DeploymentShare of Windows 7 x64.
- The reason is because the Reference PC is x86 and the Unattended.xml file can be changed only if MDT is installed on x86 Windows, otherwise it is not possible.
The image capture is successful.
Then I create bootable USB device using rufus-1.4.12.exe. I use: C:\DeploymentShare\Windows8\Boot\LiteTouchPE_x86.iso
I use a real PC (not virtual machine) and when the deployment starts
I see:
1 Welcome screen, where I select: Run the deployment wizard to install a new operating system.
2. The next screen is an error screen where I see the error:
"Wizard error
A connection to the deployment share (\\ComputerName\C\DeployemntShare )could not be made
DHCP Lease was not obtained for any Networking devices!
Possible cause: Check physical connection
I am relatively new with MDT.
Any suggestions are more than welcome.

Nick,
Thank you for the answer!
Yesterday, I figured out that I need to create an offline bootable disk.
The issue is caused, because creating a bootable disk with rufus.exe include only the ISO file and not the WIM file. That is the reason why during OS installation process it asks me for the shared folder...

How to install driver for Windows 8.1 without physical connection

I have a Photosmart 7762 printer connected to a NAS box (with wiring all very difficult to get to behind various office units) and want to be able to print to it from a new Windows 8.1 PC that is installed (again with difficult to get to wiring) in a separate room but on the same network.
The HP site for the printer says I have to use Windows Update to get the driver, but this only works if you physically connect the printer to the PC which isn't an easy thing to do in this case.
Does anyone know where I can get hold of the driver so I can use the "Have Disk" option? I have been unable to find it anywhere. Alternatively, does anyone know how to copy the driver from an existing Windows 7 install (on a laptop I could connect it to) and whether that would work?
This question was solved.

Hi,
Folow the steps listed under Download the driver for later use or use on another computer below, it will allow downloading the INF and installing those manually, be sure to follow the link to Microsoft which explain how to locate the correct package and extract it:

Issue with hostname "localhost" and general CR connectivity issue

Hello,
we installed SAP BOE with the integrated Tomcat 6. We used a Web Tier installation on the same host, but in different paths.
Tomcat was installed under /usr/sap/tomcat/sap_bobj/tomcat and the SAP BOE package under
/usr/sap/XXX/sap-bobj/enterprise_xi40. The host has two IP addresses, a physical address (A) and a logic address (B).
We want to get a setup that uses the logical address whenever possible.
We have issues with Crystal Reports for Enterprise XI4.0.
When CR ist started from the BI launch pad, then CR ist started and tries to connect to "localhost". The hostname "localhost" is communicated from BI launch pad to CR.
For sure, no communication with "localhost" is possible.
When CR is started manually and a connection to the respective Tomcat server is initiated (port 8080, servername B, context /dswsbobje) we get the
error message. please wait, no connection possible at the moment. I already read and applied SAP KB articles 1598906 and 1601997, but the issue is not solved.
1- Where I can make changes so that BI launch pad will communicate hostname B and not "localhost" to start CR?
2- Is there any local log file on the PC to check why CR can not connect, when started manually?
Best regards Bernd

we have installed BO 4.0 and Its working perfectly. we have using webi reports,
As next step recently we have installed Crystal reports for exterprise XI4.0
But we could not connect with BO server. Please guide us on below req..

Does Apple TV and Optical Audio Connection work?

I've read several posts regarding this issue and I'm a little confused. Does the Optical Audio work on the Apple TV (generation 3), because I haven't been able get it to work. I get sound but no stereo/surround sound. Yet, using the same connection out of my Receiver for my PS3 I do get stero/surround sound. Have I missed a setting on the Apple TV?

Is there away I can check the Apple TV Optical Audio connection to see if it's working? The physical connection seems to be fine. Since the connection to A/V Reciever works, as confirmed by my PS3, I can only assume the Apple TV Optical Audio connection is faulty. Other ideas on how I might validate if the Apple TV Optical Audio connection is truly "broken."

Xserve ethernet ports shows connected though no physical connection

Hi all...
We have a very strange issue in the 3 latest xserves (with Nehalem processors)that is purchsed couple of days back. The issue is, in the Network, System preference, both the ethernet ports shows green and displays as "Connected" even though there is no physical connectivity. This active state of the eth ports is visible only in the network system preference and the port state shows as inactive if we check through CLI and the server monitor. Both the ports functions normally except for these wrong info in the system preference.
Have anyone faced any issue with the latest Nehalem processor Xserves or is this be a bug in the OS X. The installed OS version is 10.5.7 and the firmware is up to date.
Please help !!
Message was edited by: SREEKAR

Call Apple Support for assistance; this looks to be a nasty error with multiple new Xserve boxes and given these are likely covered under their initial warranty, which implies there's something seriously weird with 10.5.6 or 10.5.7, or with the Xserve early 2009 boxes, or firmware, or with what the configuration tools allow.
It appears that [threadID=2021235|http://discussions.apple.com/thread.jspa?threadID=2021235] and [threadID=2021817|http://discussions.apple.com/thread.jspa?threadID=2021817&tst art=0] are the same case?
