NAC L2 and L3 Inband simultaneously does not work

Dear all,

I have a problem with the simultaneous deployment of L2 and L3 of the NAC.

I have a CASE that is configured as a real IP gateway, broadband. Previosly, I can have the NAC working on L3 deployment using PBR. I configured the ACB on distribution switch in order to intercept the traffic of untrusted user NAC.

Now our society tries to add wireless, using WLC, who have the interface vlan configured in CASES not reliable (using the section "managed subnet" on cam). the wireless run perfectly, they able to authenticate to the NAC and able to connect to the network after the authentication of the NAC.

But now users of L3 cannot reach the unreliable for performing authentication of the NAC. The CASE cannot ping even L3 user which was previosly correct.

Is there a limitation on Cisco NAC for the deployment of L2 and L3? I read Cisco that a single CASE can be configured to L3 and L2 UNLIMITED so I should work

TQ
Imad

Imad,

The way you described work is pretty close to the way in which we would have put in place.

Glad it works for you now!

  • Qosmio DX730 and Win8 - touch screen does not work

    Hello

    My wife's parents bought a Toshiba Qosmio DX730 (model PQQ11A). They have recently upgraded to Windows 8 and the touch screen does not work now.

    The problem is lack of drivers (the monitor driver reports as a generic PnP monitor).

    I have went on the Toshiba site and selected downloads driver for the appropriate model and installed a number of drivers, including recommended NVidia display drivers. There is no drivers on the site that seem to install support for Toshiba touchscreen.

    Are there no drivers available for this model Windows 8? If not, is there another solution? If Yes, where can I find them. Any help very appreciated because they have nice and bought computer Windows 8 so they could use the touch functions.

    Thank you.

    Hello

    On the page of the Toshiba UE driver you can find drivers for Win 8.
    As far as I know that you will install the Toshiba display driver for the touch function works correctly.

    I found this driver.
    Please check if you can install this:

  • Satellite L300D - installed XP and now my wifi does not work

    I spent from Vista to XP and now my wifi does not work. I was told that I don't have the drivers.
    Can someone help me? I have a Satellite L300D-01N. Please help me, I don't know much about this kind of stuff.

    Thank you

    You can download drivers Toshiba from here: http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp

    There is however no driver XP for the L300D. But I found a LAN driver for XP wireless that would work.

    Select:
    Laptop
    Satellite Pro
    Satellite Pro L series
    Satellite Pro L300

    Download and install
    -Wireless Lan Driver Realtek Semiconductor Corporation Windows XP 6.1116.1226.2007

    If this does not work, you can have an Atheros Wireless LAN card. If this is the case, look at the other models for an Atheros Wireless LAN Driver XP.

  • I dropped my iPhone 4S and now the touchscreen does not work. Is there a way I can fix it without having to buy another or should I buy another?

    I dropped my iPhone 4S and now the touchscreen does not work. Is there a way I can fix it without having to buy another or should I buy another? (my screen is cracked)

    From what I see, Apple does not screen repair for any older than the iPhone iPhone 5. I don't see off-warranty, replacement cost for 4 on their page of repair, but I'm figuring you would spend at least $200 to get a new.

    Would be better to see if your cell phone operator has the options of upgrade for you.

  • T410 AiO customer CAPS, NUM, and scroll keyboard stop does not work with PCoIP view desktop computers

    We have problems with our t410 AiO customers, where the CAPS, NUM and scroll stop lights on the keyboard do not work with view PCoIP desktop computers.

    I found the below information and a work around:
    If you use the Protocol PCoIP to display on a client system Ubuntu 10.04, the CAPS Lock, NUM Lock, and Scroll Lock lights on your keyboard do not work with desktop view. Although the lights do not work, the keys themselves work.
    Solution: Set the following configuration in a configuration file, such as/etc/vmware/config:
    mks.keyboard.useXkbSetNamedIndicator = 'TRUE '.

    The problem is this difficulty is already in place via the latest version of the HP, Z6A440, software that is installed within our Organization.

    What I discovered, is that the model that we initially bought for the test doesn't have this problem.  However, the models that we ordered since that time, DO have the problem and the solution above does not work as expected.

    The model originally ordered for test is still a customer of IOA t410... but there are 4 "under models' for customers of IOA t410... that we have to test is a H2W20AA, while those we receive and distribution are the H2W21AA model.

    No idea why, when connected to the desktop from view, that models of H2W21AA have this problem?

    H2W20AA is with Teradici PCoIP optimized, which can support PCoIP better, but H2W21AA is not with Teradici. That's the difference.

    However, the issue that you are experiencing does not matter in fact, we have not heard of this problem before. I would suggest that you do the following to see if there is no change:

    1. Go to download the latest VMware View 2.3.4 for t410, follow the instructions to install.
    2. If suggestion 1 does not work for you, try to connect to another VM group or set up a new machine virtual clean
    3. Call HP service center to save your problem for further investigation if the suggestion above did not work

    ========

    It's probably the pilots who are responsible and who may not really be later or they need to be
    re-installed anyway. The best way is to manually review using the methods below.

    References to Vista also apply to Windows 7.

    Control Panel - device - SOUNDS - look for HD Audio Manager - Mine said RealTek High
    Audio definition (this is an example and you can have an other name/maker).

    Write the description and the model double click on it - tab drivers - write down
    Version. Now click on update drivers who cannot do anything as MS is far behind certifying
    drivers. Then CLICK RIGHT on it and UNINSTALL - REBOOT - this will rebuild the driver
    stack.

    You can have the default windows or a former certified pilot and it's all or part of the
    issue.

    Now, go to the site of the manufacturer of the system and get the latest Audio/Sound drivers - download - SAVE - go to
    where you put - right-click on Reboot - RUN AS ADMIN-

    Check the Version tab of the driver in the Device Manager as the restoration of the sound card drivers often
    and then install the latest version. Restart and check after each test, not
    rare to have to run the pilot of 1 to 4 times or more. Just the version make sure you
    installed shows upward on the tab of the driver.

    Go to the site of the manufacturer of the device, and then search for the even more recent drivers and install repeat
    operating mode. Download - SAVE - go to where you put them - click on - RUN AS
    ADMIN - Reboot

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.
    http://pcsupport.about.com/od/driverssupport/HT/driverdlmfgr.htm

    Installation and update of drivers to 7 (updated drivers manually using the methods above is)
    to ensure that the latest drivers from the manufacturer of system and device manufacturers are are preferably)
    http://www.SevenForums.com/tutorials/43216-installing-updating-drivers-7-a.html

    ---------------------------------------------------------

    After the updated driver.

    Click with the right button on the speaker near clock - recorders - right click in the box - check see the
    Disconnected devices and show disabled devices - check your micro - highlight
    then on lower right properties. Make sure that the appropriate injector is selected and check
    other parameters - levels tab make sure that MUTE is disabled and APPLY / OK to change
    .

    Also in the search for some Audio Manager Panel (perhaps named after the manufacturer of the sound driver). Mine
    is the RealTek Audio Manager, yours can be quite different name if you have one.
