Team,
The DHCP server In my IOS router (adventerprisek9-mz.151-3.T3) has a couple of fixed DHCP bindings.
ip dhcp pool philipshue
host 10.22.1.42 255.255.255.0
client-identifier 0100.1788.0a64.56
dns-server 8.8.8.8
!
ip dhcp pool philipshue2
host 10.22.1.43 255.255.255.0
client-identifier 0017.880a.6456
dns-server 8.8.8.8
!
The Philips Hue light bridge registers with the following MAC address, even though a client-identifier is configured!
10.22.1.131 0017.880a.6456 Mar 72 2014 18:63 PM Automatic
This is not picked up by the configuration.
Any idea why?

Hello Dirk,
Problem is with implementation of DHCP on various OS. Some OS use client-identifier, some use "broken" client-identifier and some use hardware address (MAC).
My Ubuntu 10.04 use MAC address as identifier, so to make static reservation for my laptop, I need to configure hardware-address xxxx.xxxx.xxxx

Hi,
as already explained in a previous answer you'll need the hardware-address xxxx.xxxx.xxxx command in your host pool instead of the client-identifier command but first you'll have to clear your dynamic binding.

Thank you for the quick response. Unfortunately this is an appliance (Philips Hue lamp zigbee controller) where I don't have root access ;-)
Hope that anyone has a tip to catch these strange client-identifiers!

Hello,
It is definitely not a final solution and certainly not scalable one, but you can allow these host to obtain IP from dynamic pool and from output of show ip dhcp binding copy client-identifier/hardware-address to configure static DHCP.

that's what I did.. the last output in my question is actually from the show ip dhcp binding
10.22.1.131 0017.880a.6456 Mar 24 2014 18:63 PM Automatic
The identifier for this device is 2 characters shorter than any of the others, and not accepted with the 2 static DHCP entries I created.
Maybe this is some scenario that I have to live with as it can't be fixed.. If that's the case, just let me know ;-)

Ah! So sorry... My brain interpreted 'hardware-address' as 'mac address' and not the actuall command 'hardware-address' ;-)
Will try this asap.. Many thanks for the responses and patience..
