Hi,

Where is the DHCP server? Have you configured IP Helper-address command on switch for getting IP from the DHCP server (If DHCP in the different VLAN)?

Re: Unable to get DHCP IP for WLAN

Hi Deepak

Thank you for responding :)

I dont use dhcp server

the dhcp pool I set on Switch Border Atas (middle Multilayer Switch) I set Ip Dhcp pool for the AP and the WLAN, the AP's are able to get dhcp IP for their managements but once I connect to ssid I didnt get IP for the WLAN that I set before on the MLS

Thank you

Re: Unable to get DHCP IP for WLAN

Hi,

A few questions to get more details:

1. SSID is tunneled to WLC and WLC is having correct VLAN mapping for this SSID?

2. Is this SSID VLAN trunked on the WLC management VLAN?

3. If you assigning a static IP on the client, then are you getting the Internet or Ping from the core switch?
