DHCP BInding on 871W SOHO Router/Access point

I'm having a heck of a time getting my 871W router to do a simple dhcp binding. I want to set up dhcp binding so I can use dhcp on the client machines, but always know the ip address so I can use monitoring software or web/ip connections to fixed addresses.

I have several Apple Mac machines and they DHCP bind just fine by putting an 01 in front of their MAC address. However, I also have 4 SqueezeBox machines that do streaming music (a product of Slim Devices). When any of the SqueezeBox Machines issue a DHCP request they do not bind. After reading the documentation for IOS and understanding that the MAC address should be preceeded by 01 to indicate an ethernet device, I tried three different approaches.

1- set the MAC address in the client-identifier to just the MAC address,

2- put an 01 in front of the MAC address,

3- in desperation, put an 06 in front of the MAC address

None of these 3 variants cause IOS to do the binding.

I'm running Cisco IOS Software, C870 Software (C870-ADVSECURITYK9-M), Version 12.4(6)T1, RELEASE SOFTWARE (fc3)

Here's the IOS for the binding:

!

ip dhcp pool office

host 10.6.18.16 255.255.255.0

client-identifier 0004.2005.bca7

client-name office

default-router 10.6.18.204

!

Here's the show binding:

And here is a debug showing the failure to bind.

Any ideas or help would be appreciated!

Re: DHCP BInding on 871W SOHO Router/Access point

Take a look at this Cisco document that talks about assignment of static IP addresses without creating numerous host pools with manual bindings.
