Not on any router I've used. What you are doing is telling the DHCP server in the router to give a chosen IP address to a particular MAC address.
What I do is to connect the device/computer and let it get an IP address. Then I logon to the router and look at the DHCP leases. The list usually has the IP address, MAC address and the time remaining for the lease. I find the entry one for the device I am interested in and copy the IP and MAC addresses. Then I enter these in the reservation settings of the router. From then on, when the device requests a IP address, it gets the same one.
