I have a CentOS6 server that gets DHCP from MT router. Works fine as configured, but I need another address assigned to it. I set the server up to send a client-id of 123 when it requests an address. The MT log shows Client-Id = 31-32-33. I understand that is the ASCII representation of 123. What I haven't figured out is what to put in the static lease as the client-id that will match. I have tried 123, 31-32-33, 0x313233.
What is the proper entry for the client so this will match?

I do have another device that I have configured the client ID for and it matches.
