Hi All,

I have around 40 Access point in WLC. My DHCP server is from core switch and I want to Set all WAP DHCP issued IP Address to current IP on Core Switch based on MAC addess. How do I do this.

While I was trying to do this I get the following error.

HBR-COR-01(config)#ip dhcp pool CLIENT_WHAREHOUSE_AP
HBR-COR-01(dhcp-config)#host 10.119.98.188 255.255.255.0
% A binding already exists for 10.119.98.188.

I know Currently 10.119.98.188 is the ip that AP is getting, and it is assigned to the mac address of the AP but it will change if I reboot this AP which I want to avoid it and assign this ip permanently to this AP mac address. How to do this?

Hello!

DHCP reservations are quite unfortunate in cisco... Did you try deleting the binding? If that dosen't work you will have to delete the current DHCP pools and add them another time. 

no ip dhcp pool CLIENT_WHAREHOUSE_AP

ip dhcp pool CLIENT_WHAREHOUSE_AP

host 10.119.98.188 255.255.255.0

client-identifier XX.XX.XX.XX

you need two pool 
one include the whole IPs and other for static 

JBTECH - Cisco Router set up DHCP static mapping
