STP vs. Ether Channel ; Which one is prefer?

Is Ether Channel an always prefer method comparing to STP? Why? Is there any scenario to use STP better than Ether Channel?

Hi,
Simply put Ether Channel is the technology to combine exisiting Ethernet links and achieving higher bandwidth which is otherwise restricted cause of Layer 2 limitation e.g. can you achieve 4 Gbps bandwidth using GBIC modules/interfaces? The ans is NO. In that case, Etherchannel will bundle all the four inidividual interfaces/GBICs and give you a bandwidth of 4 Gbps.
STP, on the other hand is a technology that will enable you to give a Fault-Tolerant situation when in a Looped environment.
If you require more info please feel free to revert back and I shall be glad to give you more info.
Hope it helps, if it does please rate.

  • BI Reporting Tools - Which one to prefer ?

    We have many number of use Oracle Financials users and we do have exposure to all BI reporting tools, in addition to OFA. We are finding it dfficult to understant which tool would be the best to use in different situatoin. As we have Discoverer, DBI, OFA, ADI - It is confusing which tool to prefer in the first point, while creating reports.Also as we are in the developing end, we find it difficult to tell poeple that this tool would be the best for this sitation, as the same report could also be generated from other reporting tools.
    Could anyone tell me where I can find documentation that would help us to identify the right tools for the right situation?
    Many thanks.

    For actual reporting tools, the standard Oracle Reports is of course popular as it comes with Oracle Apps predefined reports.
    However, Discoverer is popular as it allows 'ad-hoc' reporting (which is another whole story in that do you want end users to perform ad-hoc querying) and its a tool that under 10g r2 has really come together.
    XML Publisher is definitely something that Oracle is pushing more - and supposedly a some time in the long future replacement for Reports (so I've heard but who knows if the source is correct).
    If you're referring to relational table tools, then the biggies are Oracle Discoverer, Cognos Impromptu, Business Objects, Brio, etc. However some have been bought out in recent past (ie: Brio). They all use a middle layer (ie: EUL, catalog, universe) and all have strengths and weaknesses. It's usually a safe argument to use the Oracle tool (if you can wait for it to catch up to competitors) as Oracle tools are usually tightly aligned with Oracle database, Apps, etc. But if you want more disparate sources to use the tool with, then Oracle tools (ie: Discoverer) may not always be the best one to use.
    For OLAP reporting, the big boy is Hyperion (but at a considerable cost). Now, however Oracle is really trying to kill these other tools (sorry ... compete with), with the 10g database that supports relational and OLAP in the same database and their query tools (ie: Disco Plus 10g r2) that can access both / either.
    So, it's one of those questions that always comes around again. Of course, General Motors is better than Ford, right? Same argument, but I've found that a company hanging it's hat on Oracle tools in an Oracle environment (database) and especially in an Oracle Apps shop (Enterprise Suite), usually is happy. Not always happy at the current version, but Oracle with it's humungous amount of money and resources, usually either gets their tool up to their competitor's level - or buys them out!

    Dear Kals,
    Synchronous or Asynchronous:
    If you need to process dependent transactions one after the other go for synchronous. Else, go for asynchronous.
    Asynchronous will have better performance.
    Ex:
    If you would like to process F.02. If it is successful process one more transaction using.
    Go for synchronous
    call transaction F.02 ........
    if successful.
       process one more dependent transaction.
    endif.
    If you just need to process F.02
    Go for Asynchronous.
    Background or Foreground:
    If there is a huge volume of data or no manual intevention is needed for background. If you would need manual intervention go for foreground.
    Performance would be better in Background.

  • WHICH ONE? BLACK? WHITE? HELP!!!!!!

    I am going to get an iphone shortly and wish to know whioch one to have.
    Ok simple as i want to know which one people prefer. The White or the black 3g iphone. Storage is irrelevant. How about scratches, marks, fingerprints etc.
    Thanks
    Scott

    As I'm sure everyone will tell you, it's a matter of personal taste and preference and you will know which is the right one for you when you see them in the flesh. I spent 5 weeks in Australia in the summer and the 3G was launched when I was away. I looked at both models in Oz and thought I would update to the white one when I got back, but found, of course, that only the black model was available as an upgrade at that point. So I bought the black model and played with it for a couple of days before deciding that I didn't like it. It shows off every single fingerprint on the back casing and, for me, looked a bit cheap. So I went to the Glasgow Apple Store (only one in all of Scotland!) and took out a new contract so I could get the white model. I've never looked back! I swapped SIM cards between the phones and sold the black one for enough money to cover the cost of the handset and the 18 month contract. I've since compared my phone to those of friends who have the black one, and mine still looks in the best condition all things considered. This is of course simply my opinion, but there is something a wee bit more 'Apple' about the white phone, as it is the colour used for so many pieces of hardware that they have produced. But you'll know the right one for you when you pick them up! Enjoy it when you get it - simply the most amazing piece of kit!!

  • Which one do you prefer for 2.1 Stereo Speak

    I am planning to buy a Creative Sound card for my Streo 2. Speakers but don't know which of Creative EXTERNAL solution will sound better and blast my bass when i connect it to my notebook to streo speaker.Which one do you prefer ? Thanks.

    If you have a spare PCMCIA slot, check out the Audigy 2 ZS Notebook. External solutions, there is the SBLi've 24-bit External.
    You might want to check out the Xmod though, it is a new product and seems to fit the bill if you're trying to improve the audio quality from your laptop.

  • Physical standby, logical standby which one shud i prefer?

    Hi ,
    how to decide which standby to create that is whether Physical or Logical.
    I want to create it for database failover. so which one i shoul prefer?
    pls give ur suggestions.
    Thanks,
    Kuamr.

    Physical standby is the easiest to setup and administer and supports all datatypes. You can use it for reporting (if it's rarely req'd), except for you would have to cancel the recovery, open the db is a read-only mode, and then put it back in the recovery mode.
    Logical standby is a pain, but you can run reports at anytime without canceling recovery. logical does not support certain datatypes, like IOT's, BLOBs, etc.

  • Ether channel between fiber optic ports any difference?

    I will appreciate any help about the below questions.
    there are two catalyst 4506 multilayer switches, Two SFP modules are installed on each switches for uplink purpose. (1000 Base SX fiber optic Gigabit ethernet SFP modules)
    I want to connect two switches each other. Question is;
    1.Can I bundle these two gigabit ports (ether channel) and get Two gigabit connection between switches ?
    2.If I can do it, what happens if one of the lines fails?
    I know I can configure ether channel between copper fast ethernet ports but I am not sure If I can benefit same feature for 1000 base SX fiber optic ports.
    Thank you very much for helping :)

    Hi Friend,
    You can run a command "sh port capabilities " and that will how that whether that ports are capable of etherchannel or not.
    Also AFAIK SFP ports are just the physical medium so it does not make a differece, they should be capable of etherchannel.
    Also if one port of the channel goes down traffic will start trasversing through the other port so it will take care as redundancy. It will behave like other etherchannel which you cofnigure with copper ports.
    HTH, if yes please rate the post.

  • AppleScript copy alpha channel from one document to a second document

    I have two documents. One with Alpha Channels, the other with none. I am trying to copy the alpha channels from one document into the second.
    When I use the following in PS 6, the action duplicates the channels in the same document, not in the second document. I am using PS 6 with both documents open in tabs. Any help appreciated.
    tell application "Adobe Photoshop CS6"
      set x to document 1
      set y to document 2
      set cc to number of channel of current document
      repeat with i from 5 to cc
      duplicate channel i of x to y
      end repeat
    end tell

    I can now copy-paste text frames and linked graphics from one document to another using snippets, but embedded images still don't work.
    If I embed an image from a pdf file it works but not for jpeg images. When I open the new document (for which I placed the snippet) in InDesign, there is a frame (with a dark grey background and a diagonal cross) shown, but no contents. The place() method did not throw an exception. What am I doing wrong?

  • Which one do you use?

    I recently started asking myself which stability and stress program to use.
    Theyre many, but i usually chose between those 3:
    1.Stress prime 2004 by Johnny Lee
    2.Super Pi by the japanese record breaking guys
    3.the well known prime95 (which i dont like to use to test my machines).
    prime 95 lacks information and details IMO but is reliable(at least thats what people say), and many people dont know how to use it at first sight(including me), asking themself what is s11t this for?
    super pi does not take much time to complete the 32million task, so im not sure about its reliability.
    and finally the one that i think is the best is the stress prime 2004 which i like the most, and the funcitons are there and it shows everything in details. the source is taken from prime95 but redone to give better results and details.
    so c'mon you o/cers, which one do you prefer ? maybe you can suggest another good one from the rest which you find interesting and reliable!!
    and pls no everest or sandra stress test suggestions.
    good day

    I use the following:  http://www.7byte.com/index.php?page=hotcpu
    Hot CPU pro is available in an evaluation version that doesn't perform all the tests but still has an accurate diagnostic and burn in mode.
    I licensed for the full features and find it works fantastic.   Pressing the diagnostic performs tests of the chipset, cpu, memory, hard drive and more for 6 hours and then tells me the result.   Or I can run Burn in and test it much more extensively.
    LOL .. we had quite a discussion a few years back about this .
    Here's a post thats quite amusing :  https://forum-en.msi.com/index.php?topic=63480.0
    I have experienced full so called "prime stable" test over 8 hours just having HotCpuTest fail as it just doesn't do prime numbers calculations or Pi calculations but some more and it's one of the best progs to get you down to earth when you thought your system was overclocked stable.
    In addition back then there was some faults in prime95 build x.xx (don't remember) with certain setup with A64 page file size and amount of memory.
    Was like talkin' to certain stoneheads back then .
    Read the thread through and see why not only trust one cpu calculation/benchmark prog  :D
     

  • Reading multiple channels in one task

    Hi i am trying to read three voltage inputs in one task. I have configured the task and used generate code to get the example. But i am now getting the data from all three channels in one waveform, but i would like to work independantly on the three channels. What should i do.

    Hi vamy,
    If you read all channels with AI Read, it should return an array of waveforms (not just a single waveform). You can use "Index Array" to get the waveform from each individual channel, or use "Index Waveform Array", which is basically the same operation.

  • Which one is the best practice!!

    hi all,
    i have one doubt with the lov
    can we show the data in the LOV by decode function or its better to write two LOV's based on the condition.
    which one is the best practice.
    right now i am using decode function. according to the condition the data will come in the LOV.
    Thanks..

    can we show the data in the LOV by decode functionAs you already do, you can.
    its better to write two LOV's based on the condition.It depends. If its a complex lov and only one column varies based onsome condition, it might less work to use just one lov. Personally, i prefer two different lov's

    Greetings All
    I have a vi which creates multiple stereo audio signals
    in labview 8.6.1 and I would like to play all of the stereo channels out one single Mono channel
    is this possible?  I tried setting all the device ID's to the same thing but a lot of clicks and pops occurred.  Basically I'm trying to play and mix all the signals out one mono channel at the same time.
    Please note I would like to have each signal that is created played over

     Just add the arrays if they have the same length. Use the standard add function (like in 2+2=4). Then arrays are added each index is added together
