I have a server acting as a dhcp server connected to a 4506 core switch. I have closet switches (3750s) connected to it via fiber (trunked). I would like to give those switches ip addresses via dhcp. So I setup a dhcp reservation with the MAC address of what I think Vlan 1 is on the closet switch. I get an IP address but not the reserved one. Is there something special I need to do to get that switch to get the reserved IP address?
