NEW THREAD: 10G SFP+ Auto-Negotiating to 1G?

Can a 10G SFP+ SR optic plugged into switch "A" AUTO-NEGOTIATE to 1G to support a 1G SFP SR optic plugged into switch "B" at the other end of the fiber cable?
In short, what I am asking is whether a 10G SFP+ optic (SR/LR - doesn't matter) can be connected with fiber (of course) to a 1G optic and negotiate DOWN?
If not, how do I connect that 1G sfp+ optic to a 10G sfp+ switch port?
NOTE: I know Cisco SFP+ optics only operate at 10G and Cisco SFP optics operate only at 1G. But my question is a general question about SFP/SFP+. From my understanding, SFP+ CANNOT (regardless of vendor) negotiate down to 1G because the SFP+ standard defines a speed range between 4.25 Gbps to 16Gbps. Can someone verify?

Here is one common Optic SFP that does do both 1G and 10G:
Intel E10GSFPSR and
Intel E10GSFPLR

http://www.intel.com/support/network/adapter/pro100/sb/CS-030612.htm (expand section 1)
I know for certain that they do support both 1G and 10G as for quite a while I ran these SFPs with Cisco GLC-SX-MMD, and eventually (now) Cisco SFP-10G-SRs.  No config changes or modifications were required to support this functionality.
This was in a UCS server with a supported Cisco UCS Intel X520 card.

  • 3750 GLC-T SFP Auto Negotiation

    hi all
    I have a 3750 switch that have fiber sfps. I'm planning to buy GLC-t SFPs. I want to know that whether i will be able to connect GLC-T SFP to a normal 100BaseTx port ? Will GLC-T support autonegotiation ?
    Waiting for a response

    If you use a built-in port (e.g. a 10/100 or 10/100/1000 port) then it will negotiate 100Mb.
    It's just the SFPs that won't negotiate lower..

  • As Requested New Thread DSL low speeds and drop outs ref: Anthorny Verizon.

    Please see post by Jerrold concerning the form for information requested, I have never been able to fill this out. Note also I had to sign in three times just to access your private letter to me today.
    Here is a summary of problem:
    When my line was first installed line speed was always between 9 to 12 Mps, which is fine for a 15 Mps line, sometimes would even go higher, so line was ok.
    In October 2012 my line speed dropped to about 5 to 7 Mps, I contacted support and repairs were attemped, but did not correct the problem in fact problem became worst.  My line speed dropped to about 2 to 3 Mps.
    Now from October to end of November, all repairs did not correct problem.  I was told by chat tech support that the problem was being worked on and there was an open ticket.
    In December my line speed returned to normal speed was between 9 to about 13 Mps.  No one had contacted me about this so I again contacted chat tech support who said my line had been fixed and there were no open tickets so have a nice day.  I accepted this at face value and accepted that my line was now ok.
    In January 2013, My line speed dropped again to 2 to 3 Mps.  I contacted chat tech support who tested line and put in a repair request.  No one had responded back to me and a week later my line started to drop in and out losing the connection completely.  I again contacted tech support who told me they had no open tickets on my account, they tested line and while we were talking on voice connection my phone started to have heavy static, both my DSL and Phone dropped out at that point.  Tech support called me back and said he was putting a repair request and that my line had problems. That night Tuesday January 29 my Phone and DSL both died, no dial tone on phone and DSL showed only power light on.  Contacted tech support by a friends cell phone and informed them of this, was told ok it would be fixed by open ticket for next day.
    Repair was to be made on Wednesday January 30, no one showed up, called tech support and told repair would be made on Thursday.  Thursday late repair person showed up around 4:30 or 5:00pm, landlord gave access to building.  I did not know they were here at all, when he told me( my landlord) I tested my DSL and found it running at 1.7 Mps or below that.  When I attempted to call tech support found my phone was still dead, no dial tone at all.  Contacted chat tech support who told me ticket was still open and would be fixed by Friday, or Monday.
    On Monday, phone still dead, DSL running at 1.7 Mps contacted chat support who had me take a phone to the junction box outside of building, plugged in two phones to this no dial tone at junction box (both phones work ok checked using a neighbors phone jack)  should note that on the outside of building there are two junction boxes, but one has lock on it so could not use that one.  Anyway told that DSL could not be fixed until phone is repaired.  Tried contacting phone repair and all I get is auto wait then line drops using a neighbors phone and pay phone my is dead.
    Tuesday again contacted chat support now told to bad, until phone is fixed cannot help me ( was'nt that suppose to be done in first repair, fix phone and DSL given both were reported dead).
    So why am I upset well look at history I now sit with No Phone service, DSL running way below what I pay for and a tech support who has said to bad not our problem.  I also do not want to hear that my line does not and cannot support the speed I pay for ( it has shown to support that speed at beginning of install up to October and again in December).
    Well anyway your letter did not say where to start new thread should I do that here, or in open forum?
    Oh, auto phone repair has given me a date for phone service as this Friday, I hope that at least gets done I cannot contact them any other way it seems.
    You may also ref: my thread on ping rates over 600 on long distants calls for any other history, but as per your request here is new thread.  Please note as of today I have No Phone so can only be contacted by email or here.  Untill phone is repaired that's all there is.

  • (New thread) HP SimpleSave md1000h External Hard Drive - Can't Access Files,

    New thread on same old unaswered issues from others.
    My desktop crashed.  It  needs new harddrive.
    I religiously backup my info everyweek on my simplesave md1000h
    However, before I buy a new computer or replace the harddrive on my old computer, I want to at least get my Quicken Checking account info up and running on my wife's  laptop.
    When I plug in the usb for the md1000h into the laptop,
     it recognizes the  hardware is there but, does not show any files.
    I presume my laptop needs the software to run the simple save.
    However, there is nothing out there on the HP site.
    Can anyone confirm that this is the issue...that I need the software...if so, where can I download it from.
    I beleive the softweare came preloaded on the md1000....now I cant access that software....go figure.
    Any help is appreciated.   Thanks.  Greg

    I too have the exact same problem on my HP SimpleSave (sd500a) external hard drive. I got through to WDC, and they apparently support these devices now. They asked me to send them a copy of my purchase receipt in order to extend my warranty in their system in order to help me (ridiculous!!). I sent the scanned copy of the receipt to [email protected], and got an auto-reply that they will get back to me within 1 day. I also went on their website, and they refer to the device in their system as 'ED Caviar Blue EIDE Hard Drive'. It has the same serial number as my product from HP, so I guess they have acquired these products or at least support of them (?). In any case, I'm freaking out because I have tons of family pictures, video and my entire iTunes library on the device. If any one is able to get help for this, please respond. I am desperate to get this resolved.

    Hi there,
    i have a problem concerning two new 5548UP.
    After a reload, the 2x2 10G SFP Modules SFP-10G-SR are displayed as "sfpabsent" on a random basis.
    When i plug it out and afterwards in again, they work fine an the VPC-Peer link across the two switches comes up.
    My 1G SFP modules  are all working correctly.
    I tested firware version 6.0 and 5.2.
    Any suggestions?
    Thank you very much!

  • WRT320N and Auto Negotiation at 1Gig

    I upgraded my home network with a WRT320N router.  The cable modem, SB6120 should connect at 1 Gig on the LAN side.  For about 3 weeks it showed a blue LED indicating 1 Gig.  It went to orange the other day indicating 10/100 Meg.  I connected my PC directly to the modem & the LED came on blue saying it correctly auto negotiated the speed. When I reconnected the router it also now showed blue.  Today it is back to orange & again, connecting the PC gives blue, but when the router is connected it stays orange.  This leads me to believe the router's switch is not correctly performing auto negotiation.  I look at all the info in the router and in the Linksys EasyLink Advisor and see no way to determine the speed the LAN is connecting at.  I see nothing in the cable modem details that indicates that either.  Is there anywhere this can be checked, or some third party software I need to verify the LAN speed?  This has me concerned that it changed for no reason at all.
    Thanks
    Message Edited by TonyMan on 07-08-2009 09:25 PM

    I agree with control panel showing the  PC being at 1 Gig, but that is the PC to a LAN switch port on the router.  A speed test will not show what I am looking for.  I want to know if the port on the router labeled Internet and the Ethernet port on the modem are treally connected at 1 Gig.  The router has no way of showing this & the modem LED color indicates it.  When the modem is conneted to the 1 Gig port on the router and the modem says 10/100, then I want to know why.  I would have thought that both devices would have a way to check this via software and allobe able to turn auto negotiation off and let the user set the speed at 1 Gig.
    BTW, I changed to a new cable between the devices and it's stayed at 1 Gig for over a day.  Both were CAT 5e, but maybe that was the issue.  I'll just keep watching it.

  • How to let new thread to access EJB

    I start new thread in Servlet class and I want this thread to call EJB business method but I get following error:
    javax.naming.NameNotFoundException: Name comp/env/ejb not found in context "java:"
    Probablly because thread has no credentials and so on. I know this concept violates J2EE specs but I don't know how to make timer to call business mathod every N minutes (I use J2EE 1.3 so I can't use Tiemr EJB).
    I suspect that this new thread has no credentials and no role. What happens if I set run-as some role in servlet? As I saw new thread still has no credentials and role.
    Can anyone suggest me how can I set credentials to new thread so it can call EJB business method or how to implement timer service in J2EE 1.3.

  • I am trying to have some LabVIEW code called in a New thread exit when the testStand sequence terminates

    I have a Sequence that launches a sequence in a New Thread that happens to launch some LabVIEW code.  The problem is when the LabVIEW code finishes, it will not close even when the TestStand sequence terminates. Is there a way to tell this LabVIEW code to Exit, I've tried the Quit LabVIEW function, but that causes a C++ RunTime Error.  The LabVIEW code does end though, and it is set in the VI properties to:
    Checked - Show Front Panel When Called
    Checked - Close Afterwardds if originally closed
    The sequence call that the LabVIEW code is launched from has the following options:
    - New Thread
    Unchecked - Automatically wait for the thread to complete at the end of the current sequence
    Unchecked - Initially Suspended
    Unchecked - Use single threaded apartment
    Any clues on this would be appreciated.

    Hi ADL,
    Everything should close correctly if you check the checkbox "Automatically wait for the thread to complete at the end of the current sequence" in the thread settings.
    With it unchecked, I am seeing the behavior you are.

  • I group messaged from my ipad and this has screwed up the way my messages are reveived by my friends (it creates new threads in their phones with my email in place of my contact name) I've stopped messaging from my ipad but the problem remains. Any help?

    I have an iPhone 4S and use the group texting feature ALL THE TIME. I recently updated my iPad to the latest software and made the colossal mistake of continuing my group messaging from my iPad while connected to wifi. Doing this has successfully screwed but every group text thread I am in, to the point where its very hard for those involved in the thread to keep up. When I initially messaged those I was already engaged in text threads with it created a new thread in their phones replacing my name in their phones with my email. At first this was not a big deal but ever since then the people I am messaging have become increasingly frustrated with how my messages come through. If I am messaged in a group text and respond to it, sometimes when I respond it will create an entirely different thread in my recipients phones. So at that point they have to switch threads in order to read what I wrote. The new thread that my phone creates will send the message under my email not my name (related to the contact they have me saved as in their phones). The worst part about it is that there seems to be no rhyme or reason to why or when my phone will send the message as normal or under my email like it did with my iPad. I haven’t messaged from my iPad since these problems immediately began a month ago but the issues still continue. I have tried everything to get this to stop, I’ve turned off my wifi, I’ve had my friends delete the threads that my messages create in their phones. I’ve had them delete my email in their contact lists and nothing has worked. Can you help me? Any info you could provide would be greatly appreciated.
    Note: My phone message no different whatsoever. All the threads have remained the same. The issue is what it is doing to the people that I am messaging.
        Best Regards

    I have this identical problem.  For a while my group texts didnt show up on my ipad.  Then one day they did, maybe everyone in the group started using the same os version or something.  Ever since my first reply to the group there have been complaints of multiple threads.  I can not find a pattern for when my group text's decide they want to create a new thread. (it doesnt happen every time)  Everyone in the group has deleted the thread, we've all toggled imessage on/off etc.  There still hasn't been a solution.
    Any help would be appreciated.

    How did you get to the forum? Are you trying to post to an archived forum? You may need to use a different forum, perhaps someone can tell which forum to ask such a question, or you can get a clue by searching here (as opposed to google searching).

  • Same problem -- new thread

    Hello,
    I have been reading through some of the other threads in the forum and it seems I'm having the same freezing problem with my 4th gen iPod, 50 gig, when connecting to Mac. Thought I'd post a new thread since the others are tremendously long and I have not yet found any answers.
    I have been accustomed to listening to the contents of my iPod through iTunes while at work, but one day the songs started skipping around and iTunes started to freeze. Thinking the problem was iTunes, since my iPod was working fine while not connected to the computer, I ignored it and just ejected the iPod. When I connected the iPod to my iBook G4 at home the same thing happened. iTunes froze, Finder froze, and I had to restart the iPod to disconnect it. After I did that the iPod would no longer show up on the desktop or in iTunes on either my iBook or work G4, so I restored it with the very latest iPod updater, thinking it would be a pain to put all my music back in, but it would be worth it in the end.
    Now when I try to add music to the iPod, the iPod itself eventually freezes mid-update, freezes iTunes and also the Finder and I have to start all over again. After restoring it a 4th time I got wise and decided to manually update. I have been adding 3 or 4 playists myself and then disconnecting for a while before reconnecting to add some more. This is a painstaking process, and I'm sure there is something going on here that is not my fault. The iPod has continued to work 100% normally when not connected to a Mac. The trouble seemed to appear out of nowhere, and I don't think it's a HD problem because of the fact that the iPod never freezes when not connected.
    It seems like many people with this gen. iPod are having similar problems, but I'd like to hear if someone thinks I may have done something to precipitate what is going on with my iPod. It's only a little over a year old and I see no reason why I should be having these Mac-connecting problems with it.
    4th Gen 50 gig click wheel   Mac OS X (10.4.6)  

    Turn off the PC.
    Open your MacBook.
    Open Applications > Utilities > AirPort Utility - click Manual Setup
    Click the AirPort Utility menu item in the upper left hand corner of the screen next to the Apple icon
    Click Check for Updates.
    If you have been updating your MacBook, you may already have the latest version of AirPort Utility. If so, you are all set. If you have an update available for AirPort Utility, go ahead and update it.
    Then open AirPort Utility again and click Manual Setup
    Click on the word "Status" to see if there are any messages or updates available for your AirPort Extreme. If yes, go head and update.
    In the future, use the MacBook to access your AirPort Extreme, not the PC.
    There is no need to "start over" unless you want to do everything again.

  • How can I include results of a subsequenc​e, which runs in a new thread, in the main sequence test report

    Hi!
    I', m working with TestStand Version 4.2.1. I have a main sequence, which calkls different subsequences. All these steps are properly reported. One of subsequences runs as "new thread". How can I include its results in common test report of the main sequence?
    I have markes variables of the subsequence as it is requred for test report (it works OK if it is not a new thread). If the the numerical test, which is executed in this subsequence is correct, I get no results at all. If the numeric test failed I get somewhere in the main sequence report a "red message", that test failed whithout any reference to the step or values of vaiables which were not correct.
    I tried an option "On the fly" in the Report Configuration , but haven' got any useful results. What shall I do?
    Best regards
    Solved!
    Go to Solution.

    Hi,
    I tried it but without success:
    1) I got a reference to the Thread as "Locals.Step1=RunState.Thread" for every of 2 steps which start a thread
    2) I put both "Waits" after steps with (and without) threads, at the same place, where they were before
    3) The sequence run OK, but when it came to Wait for Thread 1 it waited for ever, I had to terminate sequence
    Does it mean, that I got a false reference (suppose No - please, have a look at attached pic)?
    Or does it mean, that Waits are badly placed in the sequence (threads are already terminated)? Here is a pic of sequeces calls with Wait after them.

  • How to call a sequence in a new thread from C++ dll

    Here is what I am trying to do:
    I implemented a dll that monitors network traffic, and it also supports message handlers that can be triggered when a specific message has been received. Essentially the receipt of a message is like an event causing additional code to be executed. What I need to do is have the message handler in the dll call/execute a sequence (either is the same sequence file that originally called the dll, or in a different sequence file). Also I want the sequence to be executed within the same execution object for the purpose of result collection and report generation. I am expecting the dll to have to launch a new thread to call a sequence because of the asynchronous nature of the message received event.
    There are easier ways to achieve the same result, but one of my goals is to make it easy for a test developer to configure a message handler, by having only one step in their sequence to configure the message handler. I want the rest to be transparent to the user.
    I am unsure about how to implement this feature, so I am asking for any examples, ideas, comments before I start trying things out.

    Assuming that I understand your question correctly, it would seem to be the best way to do this would be to pass the Execution object to the DLL (either through a direct pass of the Execution object or passing the sequence context, from which you can get the Execution).  Then simply call Execution.NewThread, specifying the SequenceFile object (accessible from Engine.GetSequenceFileEx) and then passing the Thread object out as an output.  Your sequence file in which your DLL is called could then simply have a Wait step which is configured to wait on that Thread object.  What happens in this case is that the results are collected for that thread (which is being executed asynchronously) and returned as the results for the Wait step.
    Although you are probably not using LabVIEW, I have attached an example of this in LabVIEW that might be helpful just for seeing the flow.
