According to the OP you can use the Switch Config tab (and yes the switch config tab does something with the settings but it will always tag both CPU ports which is often unwanted and cannot be corrected with the GUI as the CPU ports are not shown).

I tried it with the same problems you had, maybe it is possible with tricks and magic and for very special setups but you are better of using a script.

From my notes (but that is just my opinion):
Quote:
As this is a two armed router (two physical CPU ports to the switch) it is behaving erratically when the GUI (Switch Config) is used.
So what ever happens DO NOT TOUCH the Switch Config tab (not after and not before midnight!)


Attached my notes not claiming it to be the only way and certainly not claiming it to be the best way so take it for what it is worth Smile

Many months later, after writing this, I realize this only worked because I had the WAN port disabled. If you are creating a VAP/WAP with this router and NOT using it as an Internet gateway, this method should work fine. However, if you are going to use your R7800 as an Internet gateway, this method WILL NOT WORK and you are far better off to follow the guide that @egc wrote. This has also been added to the OP.
