• Only the needs of the Cisco Aironet 1550 series a WLC?

  Hello

  Nice day.  I would like to ask if the Cisco Aironet 1550 series requires a controller to run.  Note that the references SKU in this fomat AIR-CAP1552E-A-K9-AIR-CAP1552EU-A-K9.  I noticed that on the autonomous access point there they keyword 'SAP' on its SKU while the controller based has "CAP".  If the

  Cisco Aironet 1550 Series needs a controller which controller should it be associated? (e.g. AIR-CT2500)

  Thank you

  It can work stand-alone image:

  http://www.Cisco.com/en/us/partner/docs/wireless/access_point/iOS/release/notes/15.2_2_JB.html#wp355908

  1550 relies on:

  2500, 7500, 5508, WISM2,... .etc

  check the release notes of the code controller that you have and you should be able to identify what is supported and what is not supported.

• Aironet 1142 in Configuration of the House

  One of our customers had problems connecting to their server environment terminal server home wireless. I narrowed down it to their network with wireless at home. An Aironet 1142 was purchased to be placed on their home network to ensure that wireless connectivity will not be a problem in the future.

  I'm trying to configuring it to use it, but I am unable to connect to the web interface and I don't have a transfer convenient to access the console cable. It is currently connected directly to a cisco House (not a managed switch) switch typical. I am also connected via ethernet. I confirmed that the WAP Gets an IP address from the DHCP server, but the LED on indicator flashes red, green and amber. Configuration guide mentions it will do that if it cannot reach the area of management, but in a home network I don't know really what it means.

  Any help at all would be greatly appreciated. I was tasked to deliver to the customer's home, from 08:00 tomorrow...

  So, it's a lightweight access point? And you need convert to IOS?

  Download an IOS image

  Set your ethernet IP 10.0.0.2 comp

  Set up the model as the TFTP server using the ethernet interface

  Drop IOS image in TFTP folder and rename the file: c1140-k9w7 - tar.default

  Connect the turn for the model using ethernet

  Turn on the LAP while holding the reset button in

  Wait until the light up in red

  TURN will download the firmware and reloading

• Keep the IP if the DHCP server is offline now

  We have a customer who wants to be able to manage the IP addresses of all devices with DHCP, but the devices are supposed to keep their IP forever after the DHCP server has been taken offline. Is this a behavior that we can support on a controller of NOR?

  If this is not a configurable behavior an alternative could be to have controlelr auto configure to the last known IP if no such is acquired... but the VI apply network settings doesn't seem to work if done on the controller itself. Is this correct?

  With NEITHER in Norway (thanks), I found a solution which allows us to implement the required behavior.

  The main problem for us once we need to override the default behavior for DHCP was the fact that the RT apply target Network Settings.vi does not work if it is set to target the same controller as it is running. So how to exchange between DHCP and fixed? Well, it turns out that the network settings are also stored in the file of ni - rt.ini. So here's what we do: when the controller starts, we check if it is running in DHCP mode. If this isn't the case, we change this in the file nor - rt.ini and the reset - to see if the DHCP server is operational. If the controller is running in DHCP, we check if the IP address is valid (i.e. outside the local range of link). If it isn't read us the last known IP address and write those set in the file nor - rt.ini and restart.

  An example of the sections of the INI file:

  For DHCP, the section of the nor - rt.ini will look like this:

  [TCP_Stack_Config]

  USE_DHCP = DNS_Address

  Gateway USE_DHCP =

  USE_DHCP = Ip_address

  USE_DHCP = Masque_sous

  For a static IP address:

  [TCP_Stack_Config]

  DNS_Address = 0.0.0.0

  Gateway = 10.0.18.1

  Ip_address = 10.0.18.13

  Masque_sous = 255.255.255.128

  It would be nicer than the network RT target apply Settings.vi would work for auto-reconfiguration, but it saved the day for us at least in this case.

• The dhcp server has not seen a directory for authorization server

  I recently upgraded from Server 2003 to windows server 2008 r2. After the upgrade, the DHCP server has started to not giving IP address after a lease has expired. For DHCP to provide IP addresses, I have to restart the server. I need help on how to configure my server to allow the service to restart. Any help will be much appreciated

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• Client DHCP is unable to get a valid IP address from the DHCP server.

  Client DHCP is unable to get a valid IP address from the DHCP server. I have a home edition of Windows XP attempts to connect to my router wirelessly with wireless or wired connection but I get an error in Event Viewer with the discription DHCP 1007 error message. From what I researched, I discovered that the DHCP service depends on the AFD, TCP/IP and NetBT services. All these services are correctly place and worked very well (even the DHCP service is running without error) but every time I try to release/renew my IP address I receive than DHCP warning in the case where the viewer and I just cannot get a valid IP address of the server (router) I also have one of these verizon wireless G3 usb adapters and it works fine. I also have a good ping back when I try to do a ping localhost (for the closure) I also tried the preinstallation of uninstalled drivers from the adapter/s and nothing works. The only entrees in the registry for DHCP error are also AFD, NetBT and TCP/IP nothing else there, also all the files in the/system32/drivers afd.sys netbt.sys and tcpip.sys in addition to solve the problem, I'll mention that I installed and reinstalled Northon earlier, I do not remember if the problem appears before or after that. I receive also any error or warning in the security log or at least I don't know how to read: P

  Thanks in advance

  Thanks for the information.

  I hope you know that it is risky to connect the laptop to the Internet with no firewall and no antivirus... If this laptop is already connected to the Internet in this State, he is perhaps already infected.

  You said you know the router works because the other computers can connect successfully to it.  You should check the configuration of the router to make sure that it is not configured to limit the number of IP address it supplies, and (b) it is not configured to filter users by MAC address.

  When this laptop is connected by Ethernet, even if he gets the IP address of 169.254.x.y, can you ping the router?  Find the IP address of the router on any computer connected to it by running the ipconfig command in a command prompt window.  The "default gateway" is the IP address of the router.  Run the ping command in the command prompt window as well.

  If the ping is successful, it is possible that you might be able to use an IP address in the correct range for an Ethernet cable (but I doubt that it works for the wireless).

• Disable the DHCP server on the LAN

  Hello

  I'm working on my first range SRP500 router, I used the 800 series since a certain time for installation on these devices seems a bit basic compared the SRP500 have some very attractive features.

  I seem to be faced with a need to 'simple', I want to disable the DHCP server on the VLAN by default, I already have a DHCP server on the network and wish to continue using it.

  Unfortunately it is not an X to delete this profile, how to remove or disable at least.

  Thank you very much

  Gary

  Hi Gary

  In order to disable DHCP, you must log on as an administrator and then go to-> installation interface-> LAN-> VIRTUAL local network settings

  Click the pencil beside the name VLAN to change.

  Now select the address Type "Static IP address"

  Assign an IP address and the default gateway, subnet mask is not necessary that your router will be the one to share Internet access.

  Please try this and let us know if it worked for you.

• Not the DHCP server from Microsoft for Windows 7 support dhcp/tftp bootfile name based on vendor-class-identifier.

  Original title: dhcp/tftp boot file name based on vendor-class-identifier.

  I'm trying to start a Texas Instruments AM335x Evaluation Committee using the Windows 7 USB RNDIS driver.

  AM335x is an ARM Cortex-A8 microprocessor.

  I need a DHCP/BOOTP/TFTP server which is able to select the startup file to send via TFTP, based on the identifier of the provider class.

  I have this working on the host Linux-Ubuntu 10.04 LTS. 'dhcpd' is the DHCP server.  dhcpd is able to select the image file

  based on the received BOOTP message.  For this ARM system, it serves a sequence of image files: submarine - spl.bin (secondary program loader)

  then u - boot.img (bootloader) and finally uImage (Linux kernel).  The dhcpd.conf configuration file contains the following code:

  If substring (option vendor-class-identify, 0, 10) = "AM335x ROM"

  {

  file name "u-boot - spl.bin";

  }

  elsif substring (option vendor-class-identify, 0, 17) = 'AM335x submarine SPL.

  {

  file name "u - boot.img".

  }

  on the other

  {

  file name "uImage";

  }

  Thus, the dhcpd Linux BOOTP server is able to select the correct to send from the Linux host via TFTP image file.

  based on the content of the message BOOTP ('ROM AM335x', "AM335x submarine SPL" or neither of those two.)

  Y at - it for Windows 7 Microsoft DHCP server that has this capability?

  If this isn't the case, you know a server program DHCP/BOOTP/TFTP for Windows 7 that has this capability?

  Could do you using netsh?

  Thank you for your attention,

• Change of VRA 7.1.4 static IP from the DHCP server

  Please can someone set me up the last v7.1.4 device of vRanger connection to a static IP address from the DHCP server? All the documents that I can find on it for vRanger connection does not correspond with the latest version of the device.

  Have you seen this KB?

  support.Software.Dell.com/.../146452

  The only difference I have seen in some environments, it is the NETWORK card configuration file had a different name: Ko, it is etc/sysconfig/ifconfig.eth0, I edited /etc/sysconfig/ifconfig.enp2s0

  Note. Ranger WILL has only the vi editor. If you find inconvenient, use WinSCP. It is a transfer tool, but it allows you to edit files on the Linux file system.

• Get a strange IPv4 address of the DHCP server

  Hi all

  As title, I got a strange IP - DHCP server 169.254.XXX.XXX.

  I used Wireshark, tried to get the bootp packets.  I found that my laptop 169.254.xxx.xxx used as source address to send DHCP Discover.

  In addition, there is an option called content with 169.254.xxx.xxx requested ip address. Like my source address.

  I couldn't access the Internet with this IP address.

  I was wondering, is that it is a normal behavior for windows 7 to use 169.254.xxx.xxx to send DHCP Discover?

  A DHCP request is sent through the universal 255.255.255.255 broadcast address which is one of the addresses that a server is listening. The query includes the MAC address of the applicant unit because at this point, it doesn't have an IP address. The DHCP server responds to the MAC address in order to assign the address.

  In your case, the range 169.254 is called the APIPA address and the PC actually assigns to himself because he did not see a response from the DHCP server. As you refer to Wireshark having a reading of the present.

  http://wiki.Wireshark.org/APIPA

  The customer may not send the request via this address and get a response because the DHCP server is not listening on the address or by using the range. The answer must be done via the Mac.

• How to disable the DHCP server on SRP547W?

  Hi, I bought a router SRP547W and I would like to disable DHCP server.

  On the Control Panel, I see nothing about disabling this function. I don't need a dhcp server on the router and I do not need dhcp relay.

  My firmware version is 1.2.4_003.

  Best regards

  Luciana

  Hello

  To disable the DHCP server, jusr change the type of address for your interface VLAN dynamic or - more - static.  You can define manally of the local IP address from there.

  Kind regards
