To enable trunking on an interface do we need to give command switchport trunk allowed VSAN 3-6 , or we need to make the interface part of the vsan 3,4,5,6.
Thanks

in addition to what Ernes mentioned, i will add that whenever i setup ports as ISL i typically leave them in VSAN 1 and simply trunk allow VSANs that need to go over that link. Why ? Because let's say you were using VSAN 20 and your ISL port was in that VSAN ..if you were to delete that VSAN, that port will move to VSAN 4094..which is an isolated VSAN so any VSAN that were going over that link with become isolated. By keeping the port in VSAN 1, you are sure that will never happen because you can't delete VSAN 1. My 2 cents

An interface can only belong to one VSAN at a time. You would assign the interface to VSAN 3 for example. You can allow other VSANs through that interface by using the command you specified. You also might want to look into port-channeling if that's something that interests you.
