Re: Enabling VDOM downsides
What do you mean extra license? All fortigates comes with up to 10vdom ( disregard the smaller units ) . Some are upgradeable to more vdom. Most none sml-to-medium enterprise models are fixed at 10vdoms. Until you. get into models 1000 or larger, vdoms are limited to 10, larger units have upgrade options.
note: Fortimanager can managed a fgt with 1 ,2 , 3 or 10 vdom, nothing changes from it's perspective as a manager.
FYI; Also Fortimanger has it "adom" limits also and device total managed # of devices but these are primary on the bigger managers.IIRC you can't update adom totals but total number of devices is a license option. Thank of adon as administration domains so you can partition a fmgr to allow admo-1 to managed only fgt#1,#2,#3, and adom2 can only managed fgts,#4,#5,#6
