I noticed that DHCP options could be set in two different places.

Under DHCP and Networks tabs

Is there any difference if I set the DHCP options in either of the places

The first place only has DHCP option set and the other one has both options and option set

DHCP Options tab

Is where you add your dhcp options.

DHCP Options set tab

is where you would group options together that are located in dhcp options..

Network/dhcp-options(-set)

Is where you add the options (or sets) you created to the subnet of your choosing.
