Okay. Here is something that was sent to me for infoblox
To use option 60, then you would use a DHCP filter to trigger the correct response. Data Management -> DHCP -> IPv4 Filters to get to the triggers. Give the trigger a name, then the next step is to set up the trigger rule. Go with option 60 here, then on the next page we can customize the option 43 (string ArubaAP) response. No need to set extensible attributes for the trigger rule which is the last step of the wizard.
Go to the DHCP range that needs to be modified (or the IPv4 Filter can be applied globally), Data Management -> DHCP -> Networks, and under IPv4 Filters, you can add the filter that was created above under the Logic Filter List.
You could also make this part of a DHCP template so that new DHCP ranges automatically contained the filter or option.
