cannot obtain IP from DHCP running on core router via Cisco AP1231

kaanpeker

Hello,

My access point AP1231 is connected to a Cisco Cat.EXP500POE switch. On the same NW I have 2811 is a internet router runs DHCP on it.

I cannot manage to obtain IP through Cisco AP1231 on that configuration.

Do you have any idea what I missed ?

Here is the AP config

What have you tried so far to fix it? Any kind of errors you are seeing anywhere?

Is the IP address of the server you are attempting to get an address from the same as the one the AP is on? If not you'd need to forward DHCP requests from the router to the network of the DHCP server. You would use ip helper-address to forward your DHCP request to the server that would send you the IP address in return.

Can you post the router config too?

Translation:

"Is the IP address of the server you are attempting to get an address from on the same network segment as the AP?"
