Wireless Access

Ok got another wierd one...

Somehow in my config i have the below:

ip dhcp excluded-address 190.168.18.1 192.168.18.20
This is wrong obviously.. it should be 192.168.18.1 192.168.18.20

Hoever when I try to remove it with the gui I get:  

Try this:

no ip dhcp excluded-address 190.168.18.1 

Thanks but it does the same in the CLI as it does in the GUI

#configure t
 (config) #no ip dhcp excluded-address 190.168.18.1
Failed to remove. Maximum DHCP address limit of 512 hit. You may want to exclude unused address ranges.
(config) #

Type "show running-configuration | include excluded" on the commandline so we can see exactly what is in the configuration.

Also type "show ip dhcp database" so we can see what pool you have configured.  The problem could be with the pool..

Thanks again...

show running-config | include excluded

In a last act of desperation, you might want to save the running configuration off of the controller via ftp, tftp, etc, edit it and re-upload it.  (it would require a reboot, unfortunately).

I am not sure why it is not working...

Thanks that was what I was gonna do as a last ditch effort....

That did it... downlowaded the config, modified it and put it back...All is well now..Thanks..
