Reserving multiple IP addresses on Cisco 3800 Series router.
I need to configure a Cisco 3800 series router to issue a few reserved IP addresses to a list of devices. I've created a separate DHCP pool, added HOST <desired IP address>, then added its MAC address using the HARDWARE-ADDRESS command. I've noticed the following. The client that needs to use this address is not receiving the address I've assigned and when I attempt to add another ip address and MAC address to the same DHCP pool, it replaces the IP address and MAC address I've entered.

Issue resolved. I created another DHCP pool, assigned the desired IP address for the host and configured a client identifier. I obtained the client identifier by allowing the host to obtain an address from our general DHCP pool. I checked the bindings and noticed the MAC address had 2 additional characters at the beginning of the MAC address. I'm guessing it's some sort of client ID. I enter the same MAC address into the new pool and the host obtain the desired address. Thank you for your time.
