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:
