Access Port configuration

We have Cisco TelePresence SX10 installed but I have problems with it... Switchport switch is configured with top 40 of VLANS and VLAN to the 24.Now when I attribute IP unit VC on 40 of VLAN static it not all Ping on the other hand when it is left on the DHCP protocol takes an IP address in VLAN 24 and works very well. For more to solve the problem, I have configured port switch as a single access VLAN 40 and it works fine:

Scenario1:

Switchport top 40 of VLANS and VLAN 24: VC with IP of VLAN static 40 - place: ping fails.

Scenario2:

Switchport top 40 of VLANS and VLAN 24: VC on DHCP takes IP from VLAN 24 for VLAN 40 has no DHCP scope defined - result: ping works

Scenario3:

Switchport top 40 of VLAN and not THE VLAN 24: VC with IP of VLAN static 40 - place: ping works.

Any ideas as to what's wrong in scenario 1

Thank you

Karan

The Cisco SX10 has a value for the mode of VLAN voice if it is set to auto and cdp (Cisco Discovery protocol) is present in the network the SX10 will use the value of vlan provided by CDP to crush any vlan manual.

Vote kindly if it helps.

  • Compare Dot1Q and QinQ with access ports and trunk?

    Hi all

    How do you compare Dot1Q and QinQ with access ports and trunk?

    Thank you

    Sunil Kumar

    Hey, Sunil,.

    With regard to your questions:

    1. we have a case of Dot1Q configured on the port of access of habit?  If not, then why? - Dot1q aims to tag executives leaving the switch and access is opposite, it does not therefore not used together marking.

    2. how the topology would be for QinQ case? - For QinQ as I mentioned in my last post one side will be set to while links to access than others. A simple example is explained on this link:http://networklessons.com/switching/802-1q-tunneling-q-q-configuration-example/

  • Printer port configured incorrectly, how to remove or reconfigure

    I am setting up a new system of Windows 7 Home premium and made a mistake when setting up the new machine to access one of my existing home network printers. I have incorrectly set up a new printer port and need to know how to remove it.  When I try to install the network printer now (rightly), the wizard tells me to choose another port name because what I used already exists.  The port name is unique to my existing print server (DLink DP-G321) and should be used for this printer.  Can someone tell me how to remove the bad port configuration, or get the wizard you want to replace it?  I suspect that this may require a registry hack, which I have no problem to try with the correct instructions.  Thank you

  • D DAQMx 6229 problems default IO port configuration

    Hello

    We use the PCI-6229 in an industrial PC / Windows 7 CVI application and are interested in the power setting to the top of the default configuration for the input/output digital port configuration.

    We used the utility NI Max Device Explorer and config to set the default values for the configuration of our application 26 DI + 6.

    It works very well which allows us to turn off the PC and power again upward and the Council retains its power to configuration.

    When we run our application and power cycle the PC, the power of the State seems to have returned to factory settings, which is all the output to 0 (I think).

    I don't think that we are running the functions that perform all reset of the card.

    Did someone saw this behavior like this and have any ideas of how we can know how to solve this problem?

    Thanks in advance.

    Steve Pinfold

    Hi Steve,.

    I conducted a survey on this issue, and it seems that this is a known bug and was returned in October last year.

    There is however a workaround solution.

    Cannot set the State of a single line at a time, because that will generate an error kErrorPowerupStateNotSpecdForEntirePort. Instead of so, write several DAQmxSetDigitalPowerUpStates() with different hardcoded calls a number of settings and switch between them during execution. I joined ppus_set.c, which is supposed to randomly through the adjustment lines.

    I hope that this should be a good starting point for you!

  • Printer does not work on the Windows XP computer, get the error message like "an error occurred during port configuration. This operation is not supported.

    Original title: 1. printer stopped communicating with the computer. 2 port - associated configuration error?

    I have a big problem. All of a sudden my printer - AIO Photo964 said he cannot communicate with my computer. The printer works fine. I tried switching cables USB, all the trouble shooting suggestions, etc. etc. Nothing works and it makes no sense. I can't print anything. I thought it would be that I installed a Seagate external hard drive backup, then I uninstalled the program - no help. ITunes installed recently, because she had changed the printer default, changed back - no help. The USB cable is not tight in the printer (or both cables, I tried), but AFAIK it's not new (?) And when I try to configure the port, I get the error message "an error occurred during port configuration. This operation is not supported"I have no idea what it means.  Can someone help me with this? I have to return a new printer? The USB port on the printer is repairable if this is the problem? How will I know? Who would do that?

    Thanks, I'd appreciate any help.

    It is always useful to have the complete error message without paraphrase.

    It also helps to identify the version of Windows you have, including service pack.

    And it helps to give the manufacturer of the printer in addition to the model.  In your case, I guess you have a Dell printer.  I know that some Dell printers are rebadged Lexmarks, but I don't know if it's a.

    Why you try to configure the USB port?  It cannot be configured - you've discovered.  It's normal.

    It's quite strange that an iTunes installation would have had something to do with the printers.  What printer was made by default after installing iTunes?

    You say you have tried another USB cable.  Have you tried using a different USB port on the computer? Have you checked in the Device Manager (start > run > devmgmt.msc > OK) to see if there is all the warning icons in the category "controllers of Bus USB?

    I suggest you uninstall the printer software and driver completely and reinstall by following the directions in Its first Article.

    Don't skip step 4.  After step 4 and step 5, follow these steps:

    Important: If you have a Lexmark printer, skip the following

    Open a command prompt window (start > run > cmd > OK)
    type the following in the black command prompt window, and then press ENTER after each line

    net stop spooler
    dependent on the spooler of sc config = RPCSS
    net start spooler

    Note that there is no space before the = and there is a space after it.

  • Unable to access WRT1900AC configuration page when it is configured as AP only

    Problem: cannot access configuration page of WRT1900 or by using the linksyssmartwifi or the affected DHCP an address

    Configuration: I have a domain Active directory to manage all devices in my house and customers. MY ISP is uVerse.

    I first installed uVerse and the WRT1900 as being generally configured (uVerse providing DHCP and DNS), my field devices could not resolve the local my AD server domain name. To resolve this problem, I set up my server AD 2003 to act as a router, Server DNS and DHCP (see diagram below).

    In this configuration, all connected via LAN or WiFi devices can see internet and other LAN/WiFi field devices connected.

    The only problem I have is that I can't access the configuration page of WRT1900 or by using the linksyssmartwi or the address assigned DHCP

    The 2003 Server provides DHCP to all devices in the LAN attached including WiFi LinkSys attached devices

    Server 2003 provides DNS name resolution

    in my case it seems that the opposite was true.  I reset my router, which is configured as a LAN Gateway and now I can access limited menu.  most applications have disappeared and I can't do basic as things even see who is connected.  Almost everything that is available is to put the passwords for wifi access and the router itself.

    It will not even to change channels or wifi connection protocols.  Shame on Linksys for not properly support their interface.

    The good news is the still phone app works where some of the above items can still be configured (for example, you can configure at least most of the wifi settings)

    Thanks for your help!

  • WRt160N is unable to access the configuration screen after the demotion to a lower version

    I just bought WRT160-V2 two weeks ago. The connection kept down all the minutes. After reading some threads in this forum, discovered that I was not alone. A thread under the instructions of a http://audipages.com/router/ site. So I upgraded my router for firmware v2.0.0.02 build 008. The connection is much more flexible. However, Setup screem has not come back. Now, I am not able to access the configuration with 10.10.10.1 screen. Help, please. Thanks in advance!

    After an update of the firmware, you must reset the default router, and then configure the router again from scratch.  If you have not done this since your last update of the firmware, please do it now and see if it solves your problem.  If you have saved a router configuration file, DO NOT use it.

    To reset your router prress the reset button for 30 seconds... Release the reset button... Unplug the power cable from your router, wait 30 seconds and reconnect the power cable... Now re - configure your router...

    WRT54GX4 - difficulties to access the configuration Page of the router Web-based.

    I have tried all posted to forums and knowledge for several weeks now with no luck.  I can feed the router to push and access the router's web-based interface, but only for a few minutes that she was leaving the loading to half way through and or does not load.  If I turn on the wireless side I can access the router at will without any problem. My warranty is almost over. I'm at my wits end. I would like to replace it under warranty if I can. (^ 8.

  • After installing a new HARD drive, I get a screen "control i to access the configuration utility.

    Help?

    I installed a new HARD drive on my xps 15 because the old drive crashed. Everything works fine and the system boots perfectly. Before entering the Dell splash screen, the screen "control i to access the configuration utility" appears for 5 seconds. After that, the normal boot sequence resumes. Can someone please explain to me why this is happening and what I can do about it?

    Here is a link to the screen I get started: http://s102.photobucket.com/user/alexcinie/media/photo_zpsb75f0a7f.jpg.html

    The mSATA drive is used as a cache for the hard drive dynamic - these are essentially implemented in a RAID 0 array.  See the link below (it is for Alienware, but applies to your system as well).

    If you want to keep the disk cache, you need to configure the array as shown.

  • Series 5300 MCUS are supported by the flexible port configuration?

    Hi all

    I could not find a guide to the administrator or something for the MCU5300 series. I want to learn if the ports are flexible or not. You know that it supports up to ports 20HD or 40SD. Is it possible to make this support 10HD and 20 ports SD at the same time as Polycom RMXes? Or do I have to choose a mode (HD or SD) and to use them only in this mode?

    Best regards

    From what I understand, it is the characteristics of the MSE8510 in a standalone MCU.

    On the MSE8510 is not possible, then I say:

    No, it is not possible to have a flexible port configuration.

    So yes, it is a fixed parameter.

  • Unable to access the configuration of the EA6900v1.1 web page

    Hi guys,.

    I bought a second hand ea6900, the guy had its ssid wifi in there, so I took over and reset immediately.

    to reset that, I like the reset button, waited for the flash logo and then become solid.

    I can connect to it wired and wireless, however, when I type in 192.168.1.1. He takes me to smart wifi configuration page, that requires the internet connection or the router access password, I tried admin, password, empty, etc. non of them work.

    I plugged a cable to the internet port of my router/box of fiber, and it does not connect to the internet either.

    I also tried to update the firmware, http://www.linksys.com/us/support-article?articleNum=159332

    using the management http://www.linksys.com/nz/support-article?articleNum=140001 mode

    or TFTP method http://www.linksys.com/nz/support-article?articleNum=137928

    the two did not work, he brings me to the page of the wifi chip, when I tried to access the management mode,

    and it's the same thing when I press reset for a minute. always take back me to the wifi secruit and need this password.

    These items are Linksys live chat, after they discovered that his warranty has expired
