I think you have to add "01" to client-identifier upfront. It means
Ethernet. Look at your debug output:
DHCPDISCOVER received from client 0100.0014.d965.79 on interface Vlan300
Client address is 0100.0014.d965.79, not 0000.14d9.6579
So just try to write it down this way:
ip dhcp pool mjking
host 78.1.1.2 255.255.255.0
client-identifier 0100.0014.d965.79
default-router 78.1.1.1
I saw this trouble too. Here is some notes from the manual:
"client-identifier - Specifies the distinct identification of the client in
dotted
hexadecimal notation, for example, 01b7.0813.8811.66, where 01
represents the Ethernet media type."
