The answer depends whether its a "seperately derived system" or not.
SIDE NOTE BEFORE WE PROCEED just in case one wonders: If a genny is used to power plug and cord connected equipment from on board mounted receptacles, the gennys Neutral to case/frame bond should remain intact and theres no requirement for an external Grounding Electrode connection BUT if local authority says otherwise then do what they say NOT anyone here lol
AND MORE IMPORTANT THE ANSWER DEPENDS UPON WHAT THE LOCAL AUTHORITY SAYS NOTTTTTTTTTT MYSELF OR ANYONE HERE (professional or lay persons) SO BEST CONSULT WITH THEM OVER ANY OF US
(In the comments below Im talking about a typical residential home service of 120/240 volt single phase three wire)
1) If you want to use ONLY a 2 pole transfer switch, i.e. YOU DO NOT SWITCH THE NEUTRAL only the two hots, the gennys Neutral to case/frame bond is severed,,,,,,,,The Gennys Neutral and Utility Neutrals are bonded together,,,,,,,,The safety equipment GroundING conductor is carried out and bonded to the gennys now floating (NOT bonded to Neutral remember) case/frame.
2) If you use a 3 pole transfer switch, i.e. the Neutral plus the 2 hots are switched, the gennys Neutral to case/frame bond remains in place and the Neutral/Case/Frame is all tied to a Grounding Electrode Conductor (like bare No 4 copper wire) which leads to a proper approved Grounding Electrode such as driven rod or rods or water pipes etc etc
My best free and worth the same (NOTHING) advice would be to consult with your local Utility Provider and any local governing authority AND AGAIN DO AS THEY SAY OVER ANYTHING ANYONE HERE, LAY OR PROFESSIONAL, MIGHT THINK. Ive been retired as an EE tooooooo longgggggggg and am rusty as an old nail on the latest NEC so NO WARRANTY on my opinions either, but its still my best faith and best remembered way to correctly earth ground a household generator, PLEASE see what the other professional electricians and engineers and technicians have to say also. For the 1,000 time (I so enjoy posting this every time lol) beware of taking advice from Billy Bob and his know it all brother in law Bubba who wired their own homes over a case of beer and everything works so they must be experts lol
Keep safe, consult with your Utility Provider and Local Authority, it may save their and/or you and your familys lives.

Today's Featured Article - The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
