Hello!

Could somebody help with issue?

RFS-4010, AP 7632, WiNG 5.9.6

AP connected directly to Controller - to port 2.

Thank you!

Also...it appears that you have applied the DHCP server policy to BOTH the RFS4K and the AP Profile.

Did you mean to do that?  Normally, the DHCP service would only be run on the controller or on an AP, but not both.

This function is purely optional.This essentially allows you to create customized DHCP values to be assigned to specific users. (In the case of WiNG, it only supports providing users of different User Classes with a different IP address range). 

It does require not only creating the User class info on the DHCP server side in WiNG, but also logging onto each individual user workstation/laptop/device and entering the desired User Class value as well.  The value you use would somehow describes a single user or some group of users that need different DHCP value(s) than others (In WiNG, it can only describe a different IP range to get an address from).  That User Class value you enter on the workstation side is then recognized by the DHCP server and as such, the WiNG DHCP server will provide an IP address from a different address range in the DHCP lease - based on the specified range for that User Class value that was seen used by that user in their DHCPDISCOVER or DHCPREQUEST message. 

Bottom line, if all users should be getting the same DHCP lease info, you do not need to do anything with the User Class setup.

have to be just address range 10.23.208.32 10.23.208.55

Could somebody explain what exactly mean DHCP server Class Policy and exactly what for ?

Thank you!
