Hi,

I'm lazy and I don't want to connect to each switch with console (I got around 100 switches in my project).

So I noticed that when a switch boot it's configured to receive a DHCP, and I thought to myself, it has to be usefull... so I googled a little bit and got into this Juniper document:

http://www.juniper.net/documentation/en_US/junos13.3/topics/task/configuration/software-image-and-configuration-automatic-provisioning-confguring.html

 

Exactly what I needed!

But one little problem, the good folks in Juniper used a linux DHCP server, when we use Microsoft DHCP server.

 

In the linux (ISC DHCP 4.2) server they use sub-options of dhcp 43:

     

     option space NEW_OP; option;

1. option NEW_OP.config-file-name code 1 = text;
   option NEW_OP.image-file-type code 2 = text;
   option NEW_OP.transfer-mode code 3 = text;
   option NEW_OP.alt-image-file-name code 4= text;
   option NEW_OP-encapsulation code 43 = encapsulate NEW_OP;
2. • option NEW_OP.image-file-name "/dist/images/jinstall-ex-4200-13.2R1.1-domestic-signed.tgz";
   • option NEW_OP.config-file-name "/dist/config/jn-switch35.config";
   • option NEW_OP.image-file-type "symlink";
   • option NEW_OP.transfer-mode "ftp";
     
   • option NEW_OP.alt-image-file-name "/dist/images/jinstall-ex-4200-13.2R1.1-domestic-signed.tgz";

Does anyone knows how to use the sub-options for option 43 in Microsoft? I found some manuals but they were all related to lync, and required some file from the lync installation..

Hi,

You can configure sub-options for option 43. Some examples of configuring it with Windows Server 2008 are shown here: http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/97066-dhcp-option-43-00.html

What version of Windows Server is running on your DHCP server?

This does get a little complex.

Hi Greg,

Thank you for your response.

I'm using a windows server 2012

Shtivis, how did you make out with this project?  I'm looking to do the same thing, and struggling with the DHCP option 43 setup myself.  Any tips?

Yes,

Use linux not windows.

Didn't manage to do it with Windows.
