DHCP relay does not not in in-band mode

Hi Faisal,.

wireless client does not have dhcp via a CAS server server ip address,.

Here's the scenario,

1. inband case network configuration:

Trust interface (for protected network) Untrusted interface (network management)
IP address
Subnet mask
Default gateway
Set the management VLAN ID:
Through VLAN ID managed network
IP address
Subnet mask
Default gateway
Set the management VLAN ID:
Through VLAN ID protected network

2. wireless customers in vlan rogue who is 104 and I traced the vlan 104-400 (trust vlan)

VLAN vlan untrusted trusted

140                                                        400

3 run subent

ip subent                                                                               vlan

10.161.136.5 / 255.255.248.0 140

10.161.136.5 is the trusted ip subnet VLANs 400

4. Enter ARP is not configured

in switch, reliable and trusted ports are configured as port trunk and permit reliable and trusted VLAN respectively.

When we move the client VLAN 400 wireless manually obtain ip address but when wireless client is in vlan 140 its not get ip address and in the configuration of the approved switch and ports not reliable are trunk port and using the vlan native is 1

WLC pass port is port trunk and allowed for all the VLANS

do I need to configure the ARP entries or what other configurations are required to work CASES like a DHCP relay.

Thank you

Laxman,

Three things:

-If it's in VGW, approved and non-approved interfaces must have the same IP address

-Uncheck "the passage through the VLAN ' on both sides

S ' away from VLAN 1 if possible!

HTH,

Faisal

  • DHCP server does not start - the storage control block address is invalid.

    I use a trial version of the Pro Workstation 12.1.1 on Windows 10. I seem to have a strange problem where the DHCP service does not start.

    I tried to go into the virtual network editor and then restore the default settings, which had no effect.

    The event viewer displays the following text:

    CreateFile Version ioctl(): VMnet8 (327680 393216): the operation completed successfully.

    / The storage control block address is invalid

    Checked the service and it runs under a local, verified system account permissions on the config dhcp / rental file in c:\programdata\vmware\ and both have system configured to full control. I tried to run the vmnetdhcp.exe in a command prompt to we hope to get additional information, but cannot be executed directly. I can't figure out how to get out of documented logging dhcp server in order to track down what could be the culprit.

    I tried to uninstall workstation, restart, reinstall, restart both unsuccessfully. I had version 9 workstation that was installed previously, in which the trial upgrade.

    Any suggestion would be appreciated.

    Figured it out.

    It appears during the workstation installation 9, he placed vmnetdhcp and vmnetnat in c:\windows\syswow64 folder. Pro 12 workstation puts these files in the default directory (C:\Program Files (x 86) \VMware\VMware workstation). The service was always pointing to the old location even SysWow64 after an uninstall and reinstall.

    I replaced the files SysWow64 folder workstation and services started right up.

The same configuration works fine on Windows 7 Pro host. Any help would be appreciated.

    Hello

    Thank you for using our product.

    I tried the same set upward on Win7 and Win8.1 host, both of them work well.

    So I guess that there is a syntax error when setting up vmnetdhcp.conf.

    Maybe missing ';' at the end of each line?

    An example would be like this:

    host computer2 {}

    Hardware ethernet 00: 0C: 28:D9:D5:95;

  • Windows xp does not boot in any mode

    I still can't find info on windows xp does not start in any mode.  Keep the loop on the screen where it has the Safe Mode, Safe Mode with network, last Configuration know, etc.  Any solution?  I appreciate your time.

    Do you have household XP No Boot Troubleshooting as stated in the post sticky at the top of the forums?

    They were practically useless, I'm happy that they were taking him down.

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a CD/DVD drive work?

    You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?

    Fill in the blank:

    My system worked well until: _.

    If there is a problem starting, XP is configured to automatically try to start again and you can stuck in a loop not being able to go beyond the screen boot options, or none of these startup options you choose will work only.

    Sometimes, when XP has a problem starting or falls down and tries to start again, it will give you a "short" menu of boot options and none of them will appear to be good to get your system going again.  You have tried them all!

    The options are similar to the Advanced Boot Options menu XP, but the only option that you need (disable automatic error system reboot) are not offered, because XP went too far during the boot process and offers a limited number of boot options.

    If this is the case, you must call Options menu advanced boot yourself until you do not see the option:

    Disable the automatic restart in the event of system failure

    When you get the XP Advanced Options correct start menu you want to see, he has options on it like these:

    Safe mode
    Safe mode with networking
    Safe mode with command prompt

    Enable Boot logging
    Enable VGA mode
    Last good Configuration known (your most recent settings that worked)
    Directory Services Restore Mode (Windows domain controllers only)
    Debug mode
    Disable the automatic restart in the event of system failure

    Start Windows normally
    Reset
    Return to OS Choices Menu

    You need to choose in this menu is the option:

    Disable the automatic restart in the event of system failure

    Then if XP does not start normally, you will see an error screen with information and clues about the problem and then you can decide what to do next.

    If you do not see the automatic restart on system failure option turn it off, you must reset your system and start typing the key F8 on the keyboard until you see her disable automatic restart on system failure option.

    If you miss the window of opportunity F8, you must try again and start tapping the F8 key with more urgency (earlier and more frequently) until you see disable automatic restart on system failure, and then select.

    You must keep trying the F8 menu until you see disable automatic restart on system failure option, and select it.

    If your system has a Blue Screen of Death (BSOD), we need to know what the screen says:

    Here's a BSOD example showing information you provide:

  • After you have installed SP3 (on XP with SP2), the PC does not restart in normal mode, only in safe mode

    After you install SP3, PC does not restart in normal mode, only in safe mode, without giving a clear indication of what is the problem or how to fix it - other than say to check settings in the Panel (not very useful).

    PC is a Compaq Presario desktop with AMD processor, model #: SR1720AN product #: EL540AA-ABG

    I reinstalled the operating system recovery disks, which reformats HD and installed XP with SP2.

    I then installed the SP3 from a flashdrive (361 MB files). Everything went without hiccups, but final restarts, he won't get to normal mode, safe mode only.

    I did it twice.

    Any ideas? Thank you.

    Here are the specifications of your desktop Compaq Presario SR1720AN. According to the specification, this model comes with a processor AMD and Windows XP Home Edition SP2 installed at the factory. According to your description, it seems that the HP recovery discs may have been poorly photographed for an AMD-based computer. Please see this Microsoft article and this HP document about your problem.

    To solve your problem, please reinstall Windows XP SP2 by booting from your HP recovery disks. After Windows XP SP2 is complete restored and that your computer is operational, download the "Windows XP SP3 with AMD CPU upgrade utility." Run this utility, and then restart your computer. Then download the "Windows XP Service Pack 3 Package of Network Installation" for it professionals. You can also try to use the SP3 Installer on your USB. Install the update to Windows XP SP3 and then restart when you are prompted to.

    This solve your problem?

  • Vista 64-bit Black Screen of Death, with just a mobile available slider, the system does not start in safe mode.

    My system worked properly on 25 April and then something happened and now the machine comes back with "Start menu options" but will not start in one of the listed options, modes result in the same outcome.  System also starts on the Vista CD.

    System begins to boot normally, shows the tracer Green Windows at the bottom of the screen, then the mouse pointer appears and moves but the rest of the screen remains black.

    That's it, that's all what he will do.  I checked the settings of the computer and ran the diagnostic tests available and everything seems to go fine and passes all the tests.

    I worked on my own computers for over 20 years and never been stumped before, but I must say this is a first, and I have no idea what to try to do it now.

    Help or direction is appreciated.

    original title: Vista 64-bit Black Screen of Death, with just a mobile available slider, the system does not start in safe mode.

    See if there is a way to tecover clean your data before doing a restore to conditions of factory that will wipe the drive of all.  You can use Knoppix http://www.knopper.net/knoppix/index-en.html with a good ISO as Copier: http://isorecorder.alexfeinman.com/isorecorder.htm as well as a blank CD (which you will need to do on another computer).  Starting on this disc and lla should give you enough access to the system (if you do not have any other means) to backup your important data.

    So since you seem to have no other alernatives, you can try retoring the original factory computer options. However, if it is a hardware problem as could very well be the case, you can still encounter problems after even this drastic step.  Then you will need to consider in a reputable computer repair shop (NOT Geek Squad or or a any of these big store centers) or maybe even go back to the manufacturer for repair.   Check out several options and compare the costs, quality and guaranteed and then make your best decision.

    I hope this helps.

    Good luck!

  • "Windows Vista Security Center" close browser windows, precise I have a virus, and now no programs will be opened. Windows does not start in safe mode, and all the system restore points have already disappeared.

    Hello

    I have a Dell laptop under Windows Vista Premium. I got it for about three years, and he is upset enough ok tonight. In the middle of browsing the internet, check my email, etc., all but one of my browser windows close at random, and a message appears "windows vista Security Center" whenever I try to open a new window, blocking of the site and to say that the site is dangerous and my system has been infiltrated by a Trojan horse. Then he starts the scan and says that I must buy the full to get everything to work again. I closed everything, since I already have McAfee antivirus and internet security, but it does not, and neither did any other progams. I tried restarting in safe mode to restore a backup point, but Windows does not open in safe mode, rather stick for half an hour in the middle of loading. When I managed to start windows in normal mode, I found that all my past restore points had been erased.

    This happened to someone else, and it is fixable without wiping everything?

    Thanks in advance,

    This could be due to a virus on your computer.  Try to make a virus on your computer scan to check if your computer is infected.
