PXE-BOOT Not working??
 
I have setup a Management Station which is a server provisioning server.Whenever any other node on the same VLAN gets rebooted and we press F12 for PXE-BOOT then it will be connected to that Management Station and installs complete OS therwith.

Now When I tried it without VLAN its working but its not being PXE-Booting when I put it in VLAN.

The machine is now by default with OS and its pinging to the management station.But On rebootign and pressing F12 its not being connected to the mgmt station..

I tried:

#tcpdump -i eth0 --port 67 or port 68 or port 69

BUt it dont display anything?Pls Help

Maybe I don't understand. You can assign a (server) network interface or a switchport to a VLAN ... but I don't know how that could be accomplished upon PXE boot?
Of course, if the PXE server is on another VLAN that the client is connected to, there will be no talking ....

The Machines all are on same VLAN.
I checked with logging on into Management Station through this command:
Its shwoing:
Code:
mgt# tcpdump -i eth0 port 67 or port 68 or port 69
tcpdump: listening on eth0

But it means that the Server which is PXE booted is able to trigger the MANAGEMENT STATION.
But wonder why it is not able to boot from the machine.
