Hi,

Need some advise, some of my AP encounter the appended 0.0.0.0 ip addressing with state either is associated or association processing, Need valuable feedback, Thanks

Device Type Name IP Address MAC Address State Parent VLAN

AP is a layer 2 device. Within 802.11 authentication and association or 802.1x authentication process, the AP does not pick up IP address of the wireless client. The AP learns the IP address of the wireless client when the wireless client sends out an IP frame.

What you are seeing may be normal. Do you configure static IP address on the wireless client? Or does the wireless client get an IP address from a DHCP server?

all the wireless client get ip address from the DHCP server. The wireless client keep at this asscociation processing atage . The same mac address stuck there till Client off power (after work).

do the wireless client get an IP address from the DHCP server? Do you enable encryption?

If encryption is enable (i.e. WEP), I will disable it and find out if the wireless clients can get an IP address or not. If you disable encryption fixes the problem, I think that the static WEP keys on the wireless clients and on the AP do not match.

Yes all the client get there ip address from the DHCP server, yes it is encryptiob with wep enable, The wep key is dymanic not quite possible for the wireless client to know the wep, Your advise please. Those client are centrino CCX mostly

I am confused. If you want dynamic WEP keys, you need to enable one of the 802.1x types or WPA-PSK.

From the output of show dot11 association, the state of the wireless clients is "Associated." If the clients use one of the 802.1x types, the output of show dot11 association should show the state as "LEAP-Assoc" or "EAP-Assoc" I deduce that you configure WPA-PSK. Can you confirm that you use WPA-PSK? Please post the AP configuration.

The configuration looks OK. What kind of 802.1x type do you use? show dot11 assoc should show EAP-Assoc if the wireless client is EAP associated, which is configured on the AP. I have the following questions:

1. If you configure static IP, do you have IP connectivity?

2. Please go to the radius server log, do you see the radius server grants access to the wireless clients?

Hi,

Thanks for the prompt reply, Currently we've peap, eap-tls and leap authenication, I presume all are 802.1x,

1. If you configure static IP, do you have IP connectivity?

Yes I able to get connectivity to the AP

2. Please go to the radius server log, do you see the radius server grants access to the wireless clients?

FYI all the client are using Active direvtory for authenicated.
