Enabling DHCP reservations on M4250

Hi all,

I am trying to add a couple of MAC address to a DHCP reservations list through the management Web UI of my M4250. I have already set up a DHCP pool and had the server assign IP's, now I want to move a couple of my NDI devices to maunally assigned an address within the DHCP server.

What I am doing is;

1. Afrer setting up the DHCP pool
2. I go into "DHCP Pool Config"
3. Have my pool selected under "Pool Name"
4. Change the "Type of Binding" field to "Manual"
5. Enter all the required information, including the "Hardware Address" and "Client ID" (the MAC address with 01 at the front)
6. Then hit "Apply"
7. And then I get this error
   1. "Error! Fialed to Set 'Hardware Address' with xx:xx:xx Error! Failed to Set 'Client ID' with XX:xx:xx:xx Error: Could not set host because neither hardware address not client-identifer is configured. Please configure hardware address or client-identifier for host first"

Do I need to set the MAC address that I want to use somewhere else first, if so where? I can't find any information on this. I have definatlly set the hardware and client id fields because it reads them back to me in the error.

Hopefully someone here has an answer because I don't see why this should be this hard. Thanks in advance.
