Virtual PortChannel Technology
Virtual PortChannels (vPCs) allow links that are physically connected to two different Cisco® switches to appear to a third downstream device to be coming from a single device and as part of a single PortChannel. The third device can be a switch, a server, or any other networking device that supports IEEE 802.3ad PortChannels.
Cisco NX-OS Software vPCs and Cisco Catalyst® Virtual Switching Systems (VSS) are similar technologies. For Cisco EtherChannel technology, the term “multichassis EtherChannel” (MCEC) refers to either technology interchangeably.
vPC allows the creation of Layer 2 PortChannels that span two switches. At the time of this writing, vPC is implemented on the Cisco Nexus® 7000 and 5000 Series platforms (with or without Cisco Nexus 2000 Series Fabric Extenders).

  • Difference Between Port Forwarding and Port Triggering.

    Hi guys,
    I'm lost! The differences between port forwarding and port triggering is driving me nuts! It all seems very subtle to me. Can anyone explain to me (in a very simple way) what exactly are their differences. Thanks in advance!!

    Port Forwarding
    The big difference between this and port triggering is that forwarding is fixed.. you forward a port and it is always forwarded.. IE available to connection.. basically the forwarded port is excluded from the fire walling abilities of the router.  Second it is static and applies to one machine only. Whereas you could set port triggering to the router and thereafter any machine on the LAN can trigger it unless its already in use.. port forwarding must be specified for each individual machine.
    Port forwarding requires you to give each PC on the network its own unique static IP address.. Although there is ssh port forwarding that can be set dynamically. Most users only have the option of static ip port forwarding.
    The real downside of port forwarding is that it can be very tricky to set up... You may have to allow a series of ports on a machine and have to do that for each machine you want to allow through. Also routers often have limited abilities and may not allow you the ability to forward a port or select the service you require.
    Port Triggering
     This is a way of Dynamically assigning a service to a port WHEN it is required by an outgoing service. The port is initially not allowed so nothing can get in and you are protected by your network.  
    A good example of this is when using Yahoo! voice .. the voice works fine for a few minutes after you connect to Yahoo! then Yahoo! sends some kind of packet that requires a response from your PC... The packet is allowed in through your router no prob but the outgoing reply is not authorized to open a port on the router and is thus blocked.

  • What is the difference between Video-out and mirroring?

    What is the difference between Video-out and mirroring? I can't get iPhone 4 video to work on my TV screen
    I have just bought an MD098ZM/A (Apple 30-pin Digital AV Adapter). I am struggling to get it to show a picture on my TV. I know I'm doing something right because the audio is coming out of my TV speakers but no picture on the TV screen.
    I have used the same HDMI channel (on the TV side) with the same cable and my thunderbolt port (MacBook Air) without any trouble - and on the same app (BBC iPlayer download then full-screen mode).
    Now I note that the packaging for the MD098ZM/A says video-out on iPhone 4 but mirroring only on iPhone 4S. I only have an iPhone 4 (not the 4S). Now if the lack of iPhone 4 support for mirroring means that I can't play video material out to my TV, then in what sense is there any video-out capability at all?
    There is only safety and warranty paperwork in the Apple adapter packaging - no help information. And I haven't found further guidance online either.
    I do note somewhere online that it suggests that basic non-mirroring video-out (for this adapter) only works with some external TV sets. Any way of finding out which? I'm using a Sanyo CE32LD90-B LCD TV if it helps.
    So far not doing very well.

    Now found these but have had to give up on this adapter!

  • Troubleshooting hints - differences between development environment and release environment

    Hello,
    I am using LabVIEW 8.6 for an application involving stepper motors.  We are using 2 Velmex stepper motor systems to run PIR targets for a manufacturing test.  The problem I am having is that the program runs fine in the states where it was developed but hangs approximately every 10th run when running in the manufacturing environment in China.  Since I am on the EAst coast there is the 12 hour time delay, and I am planning on doing a live support call to find out what is going on.  The person who installed the code made some modifications, but I am not aware of the differences.  He also may send his code here and see how it runs.
    The assumption I am making (based on past experiences from here in the States) is that the stepper motor interface is hanging.  since I can't recreate the problem here I can't troubleshoot it.
    With a past prooject I was working I did some code on one machine, and when I ran it on a different machine the order of execution for items in a sequence was different between the machines.  Has anyone run into this before?  Unfortunately for the task at hand the stepper motor has to run at the same time that analog data on multiple channels are being acquired.
    Any suggestions?
    Mike
    Mike

    Thanks for the reply.  I did think about putting in a producer-consumer.  It turns out that there was a problem with the computer it was being run on.  The computer was changed and the problem got better, although it did not go away.  The stepper motor was done through a com port talking to another hardware / software solution.  The tasks are truly independent and pass no data between them.  However, the other task being run involves collecting analog data and updating on a chart (and in one instance stimulating an analog output), and when the stepper motor starts the analog data collection is not updated on the chart.  I figure this could be because the charts are a memory hog.  No data is lost, and it is running, so I figure if it's not broke don't fix it.  It now occasionally locks up. I can run it here for 100 times with zero lock ups, and the last report I got was it ran 30 times in china before locking up.  I may have to start examining differences between their machine and my machine.
    Now as to the configuration management.  It needs to be clarified a wee bit.  I'm doing the initial code development / updating, and then we hand off to china, which can make code tweaks as needed.  They also have 3 lines running this program, and one of the items I did was to load the differences between lines from configiration files (INI files), and that I got working well.  We have fixture variables, items that vary between lines, and configuration items, which are I/O lines and what not.  The digital I/O and analog I/O referenced MAX tasks, and that worked well.  There are also a com port call for the stepper motor, and in another program an RF power meter, which had to be referenced from an INI file.  I will reccomend that they do their code development on one machine and create executables to store on the production lines.  We have been bouncing code back and forth from the team members from the states that are currently in china doing the install.

    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?

  • What are the major differences between the air and the pro

    what are the major differences between the air and the pro?

    In a nutshell, the Air is a lightened, more compact system than the 13" Pro counterpart. The Air loses some hardware features to accommodate the physical downsizing.
    No FireWire port
    No built-in optical drive
    A lesser performing CPU to retain battery charge life, and adequate cooling.
    No Ethernet port
    No Kensington lock slot
    The Air does have a superior native resolution at 1440 x 900, and a standard SSD that does make up alot of the speed differential, and then some. Of course, the 13" Pro can be optionally configured with an SSD.
    You buy the Air if the physical size an weight savings are demonstrably more important than the features lost.

  • Difference between business service and business system in SLD

    hi all,
    i m very new to XI. can anybody tell me that what is the basic difference between Business Service and Business Systems?
    Is it necessary to use them? and if yes then when to use what?
    Thanx.
    Regards,
    Kunjal......

    Hi Kunjal,
    In SAP XI every system in your landscape with which you are interfacing is defined as Service.
    The service can be your Business service or Business system.
    Generally SAP systems are referred to Business system and you define them in the SLD before you import them.
    The Business service is a logical name referring to any system in your landscape.
    To communicate with any third party application you need to create communication channels which are associated to your service.

  • Differences between B2B IPCUI and CU50 IPCUI?

    Dear all.
    We have SAP ERP 6.0 installed with integrated IPC in VMC running. On another box we have NW 7 with E-Commerce 5.0 and TREX 7.0 and MS ISS 7.5 running.
    We have two scenarios:
    Scenario 1: http://host:port/b2b/b2b/init.do
    After a logon a shop list appears. After going into a shop, navigating through the catalog and choosing a configurable product, the IPC UI gets displayed.
    Scenario 2: SAP Gui transaction CU50
    After choosing the same configurable material as in scenario 1 and running it through the IPC, the IPC UI gets displayed.
    The IPC UI via CU50 shows correctly status ligths as configured through XCM parameter appearance.showstatuslights=T.
    But the IPC UI in the B2B does not show the status lights, but the texts.
    My assumption is that both scenarios are using the same IPC UI.
    Or is there maybe a difference?
    What I also do not understand is:
    Why do I have XCM configuration for IPC two times?
    One "Internet pricing and configurator" in ../ipc/admin/xcm and another "IPC" in ../b2b/admin/xcm
    Maybe this is a silly question, but I haven´t found any solution nor answers to these issues and questions after long investigations.
    Thanks and regards
    Stefan

    Your Scenario 1: uses IPC-SCE (Configuration Engine) for runtime configuration of a configurable product. This uses the IPC as the runtime engine for configuring the product. The IPC UI (along with appropriate Java application) helps you render the design and get your input.
    Your Scenario 2: SAP Gui transaction CU50  uses the classical Variant Configuration LO-VC module of the SAP R/3 (ECC 6.0) system. The SAPGUI Variant configuration screens don't use IPC at any instance.
    The IPC UI via CU50 shows correctly status ligths as configured through XCM parameter appearance.showstatuslights=T. But the IPC UI in the B2B does not show the status lights, but the texts.
    It is very likely that you are seeing the default behavior of CU50 set elsewhere. Try changing the XCM setting and see if CU50 display property changes.
    My assumption is that both scenarios are using the same IPC UI.
    Not correct.
    See more detailed functional differences between IPC-SCE and LO-VC at this link Comparison of SCE and R/3 Variant Configuration.
    Why do I have XCM configuration for IPC two times?
    One "Internet pricing and configurator" in ../ipc/admin/xcm and another "IPC" in ../b2b/admin/xcm
    Technically they are  two different applications for use in different contexts. ../ipc/ for both design time and runtime of product configuration. This is what actually controls the IPC UI appearance in the web. The ipc component in the ../b2b/ application is for picking up the right configuration type that is defined in XCM of the _ipc application _.
    Maybe this is a silly question, but I haven´t found any solution nor answers to these issues and questions after long investigations.
    Probably, this was "intuitive" by SAP standards, so they don't have any documentation for developers who don't work in SAP.....
    (1) Define a custom configurations for application configuration  isab2b and isacatalog in ipc/XCM.
    (2) After making changes to ipc application (XCM) for UI settings, you have to restart the ipc application.
    (3) Define custom component for application component ipcdefaul in b2b/XCM
    (4) In the place of isab2b and isacatalog, input the names of the custom configurations you defined in ipc/XCM
    (5) Restart the b2b application.
    Hope this helps...

  • What are all difference between 11g Mediator and 10g Oracle service bus.

    hi all ,
    Apart from SCA concept , storing location
    is thr any other difference between 11g Mediator and 10g Oracle service bus ?
    thx in advance..

    11g introduces the SCA architecture for building the service infrastructure.
    SOA 11g uses:-
    1. Uses the weblogic Server and BEA Aqualogic Service Bus (ALSB) for the Oracle Service Bus.
    2. BPEL uses scalable DOM with reduced memory usage.
    3. New adapters and leverage for Java 2 Connector Architecture (J2CA)
    4. BAM finally ported from .Net to J2EE and is part of the service infrastructure
    5. Oracle Web Services Management built into SOA 11g service infrastructure
    6. New adapters and leverage for Java 2 Connector Architecture (J2CA). Tighter integration with E-Business Suite & large payload support.
    7. Business Rules in SOA 10g business rules are managed using the Rules Author & in SOA 11g business rules are managed using JDeveloper and SOA composer

  • Difference between SAP SLD and SAP Management console

    Hello,
    It seems that both System landscape directory and SAP management console have some overlapping features. The services can be started or stopped in both. Is it true? Does anyone know the difference between these 2 and where does Solution manager fit in?
    Thanks
    Shailik

    Hi,
    SAP SLD  is the central information provider in a system landscape.this contains both Component information and Landscape description.COMPONENT Info in sense all the sap products and components along with their versions, And also third party products also.LANDSCAPE desc in sense the description of all the systems in particular landscape.
    Example:This can shows exact idea for you.Components like CAF,Webdynpo(WD-java),BPM etc info.And the host names,Message server ports etc.Here we dont have start/stop functionality.
    SAP MC provides a common framework for centralized system management. It allows you to monitor and perform basic administration tasks on the SAP system centrally, thus simplifying system administration. Using the SAP MC you can
    1.Monitor and control (start, stop, or restart) the SAP system and its instances with a single tool
    2.Monitor system alerts
    3.Display the list of all access points to an SAP system etc.
    We can see difference by looking into http://<host name>:<port>/index.html
    Look and feel are also differ.
    For more info you can go through these links of sap help.

    Nope, two names for the same thing.
    You may have to change some settings of either the TV or the Panasonic system to output to the optical port (TV) and input from the optical port (surround receiver).
