Wondering if anyone can help me, if at all possible?!
Wondering if it is possible to have a DHCP server hand out only one ip adress to a spesific port on an EX switch?
I want eg. port 48 to give out the adress 192.168.1.90 no matter which machine/equipment is connected to it.
All other ports will give out in the range 192.168.1.1-192.168.1.254 as normal.
To make this even more complicated I want to run the DHCP server on one of my Microsoft servers.
So in essence, lock one port to give out one spesific adress thru DHCP.

You may be able to do this - make sure the RVI for that VLAN is on the same switch and the DHCP server is in a different subnet. Then look into forwarding-options helpers bootp dhcp-option82. This appends the incoming interface to a DHCP request, so the server can identify port. It's been a while since I've used MS DHCP, but you may be able to allocate an address based on the contents of the Option 82 field.
Hope this helps - post back here if you get it working
