Hello,
I am using the latest version of Mobility Express, on my Cisco AIR 1562. Everything is working perfectly apart from the fact I have a handful of devices that have IP addresses reserved by Mac in my Windows DHCP. However when my clients connect to the AP's they pick up a normal DHCP address, not the reservation, however when the clients connect to our older generation AP's they pick up the reservation they should.
Any ideas?

I resolved the issue; the native VLAN was not set to my trunk native VLAN.

If i were you, i always cross check the MAC Address. may be some typo issue

In addition to last my message, what is the range of IP address you reserved for vs what is the DHCP lease IP you getting currently, please compare.
if both are different, you need provide more information about your setup or investigate more.

Hello, thanks for your reply.
I know the MAC addresses are correct as when my clients connect to the older AP's as opposed to my new 1562's they pick up their reserved address.

You have not answered the basic question asked before :
When you think you got wrong IP what is that IP you have served DHCP compare to Fixed IP you reserved in DHCP ?

Sorry I missed your "basic" question...
My DHCP Scopes are 172.16.100.x and 172.16.200.x
My fixed IP's are 172.30.x.x this is on VLAN 30

You answered your question, you reserved on ther other subnet, and you looking to on other subnet.
So fix the network to bring in to same VLAN to get you right IP.

But that doesn't explain why it only happens on my new access points?
When my old ones are on the same range and setup as the new ones.

I would suggest to re-review the config, iam sure there is another DHCP getting the IP, or check are you connected to Right AP.
check the SSID
Login to AP and confirm the Client list your Laptop
check the AP configuration / WLC configuration for the same.

Hiya, thanks for your reply.
Unforunately, there are no DHCP pools created on the controller or AP. I was reading about this;
