I have a WINDOWS DHCP and HP & Cisco Switchs.
With HP Switch the Access Points get there IPs from Windows DHCP and connect to OV2500 with option 138. But with the Cisco Switchs the Access Points get the IPs from Windows DHCP but still in express mode.
I checked in Cisco with Wirechark, the option 138 is getting in DHCP offer.
I resert the APs but still egnored the OPTION 130.
(I tested olso with Option 43, still work with HP Switch only).
Thank you for helping
