Start > Programs > Administrative Tools > DHCP. Now expand your server scope by clicking on the plus sign (+) next to your server name, then right-clicking on Server Options below that server, then selecting Configure Options.

Scroll through the list of DHCP options until you see option 060, and then check the option to turn it on. Click OK, and then close out of the DHCP settings.

all the best

Option 43, all you need to input is the IP address.
Option 60,  this article might prove a bit more helpful: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/97066-dhcp-option-43-00.html

Actually you need to configure the scope using the Hex value of the WLC IP. Convert the IP to Hex then append the TLV of f104 to it.

Using the IP won't work as the TLV needs to be configured also.

Your string would be f1040aaa1702

Tks what is TLV

 Should I covert the IP address to hex  and put in the string value in scope option 060

Do I need to put any value in scope 043 ?

Thanks

Hi

Correct me I should covert IP address to hex and append in the scope option 43

No string value in scope 060

Hi

After convert I have this hex number f104 0x0AAE19BB example.

Should I just append in the scope option 43.
