I have a few 5508's at a few different sites and so far I have 2 seperate issues that may be related.The first is affecting only HP 4520s Laptops. I have setup an WLAN called "student_wlan" and it is set to use WPA2 with a psk via TKIP.
Other clients can connect to this wireless Ok. This is where the HP gets to (there are 20 laptops of the same model, it seems to be a bit of a mixed bag, some would connect, where others wouldn't, they are all imaged the same)
Policy Manager State 8021X_REQD - after this point they drop off the controller. The client just shows "Acquiring network address".
Now at another site I have a similar issue with Apple hardware only. I have checked both sites for any mac filtering or client exclusion policies.
I did a wireshark cature of the vlan that the wlan is associated with and I could see the gateway for the vlan was requesting an address, the dhcp server was offering, but there was no ACK. I also checked the DHCP required setting on the wlan and disabled that and re tested to no avail. I was getting ARP Poison in the logs, but that was just a symptom of the ipad getting no dhcp and assigning a 169.* address which set off the controller due to the dhcp required setting. The iPads are working OK with dhcp required off and static IP's.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
