Hello there,
I hope that you can help me. I'm trying to configure a manual binding with a macbook pro but I have no idea why is not working...
This is the configuration that I have configured:
rtr#show run | sec ip dhcp pool MBP
ip dhcp pool MBP
host 192.168.1.5 255.255.255.0
client-identifier 01d8.a25e.945a.b3
default-router 192.168.1.1
dns-server 8.8.8.8 8.8.4.4 200.33.146.197 200.33.146.201
rtr#
The problem is that I'm receiving the ip address of the global dhcp pool:
rtr#show run | sec ip dhcp pool Wireles
ip dhcp pool Wireless-Clients
network 192.168.1.0 255.255.255.0
dns-server 8.8.8.8 8.8.4.4 200.33.146.197 200.33.146.201
default-router 192.168.1.1
rtr#
This is the output from the debug ip dhcp event:
rtr#

I tried with hardware-address and client-identifier with the same result...
Hope that someone can help me!!!
Thanks a lot and have a nice day

Can you try same procedure with hardware-address d8a2.5e94.5ab3 and if it not working with client-identifier 01d8.a25e.945a.b3
Regards.

Hi,
In your static pool change client-identifier 01d8.a25e.945a.b3 with hardware-address d8a2.5e94.5ab3
Regards.

Hello cadetalin and thanks for your reply. I already tried that with the same result. I read in Cisco that when you use a differnet OS than Windowns you should use hardware-address... Actually I have other manual binding configured on the device with windows as OS and that works just great!!!
I have no idea what I'm missing or what should I configure besides what is already configured... :S
Thanks a lot!!!

Isn't this address already leased? do a show ip dhcp binding x.x.x.x where x.x.x.x is the ip add you want to give your host.
Regards.

The MBP is receiving the next ip address 192.168.1.25, let me send you the show ip arp:
rtr#show ip arp 192.168.1.25

Greetings!!!

ok,
so shut down your dhcp server interface then clear ip dhcp binding *, next change hardware-address 01d8.a25e.945a.b3 statement by
hardware-address d8.a25e.945a.b3
release DHCP binding on MBP then reopen interface of router and renew DHCP binding on MPB.
Regards.
12-08-2010 01:25 PM
Same result!!! :S
I have no idea what is missing. Just one thing, when you asked me to configure the command hardware-address d8.a25e.945a.b3 it changed it automatically to the XXXX.XXXX.XXXX format, let me send you the output:
rtr#show run | sec ip dhcp pool MBP
ip dhcp pool MBP
host 192.168.1.5 255.255.255.0

I already reboot the device with the same result. I'm not sure that the Macbook have exactly the same RFC that uses Cisco on DHCP.
Thanks again

I have no idea why when I configured again the client-identifier with 01 starts to work...
Thanks a lot for all your help!!! this was really helpful... So I need to use client-identifier with a differnet OS (not only with Windows)... I read that client-identifier was only with Windows...
Thanks again...
