can I assign multiple vsans to same vfc?

I am setting up FCOE on the N5K and the server team is asking if we can assign 2 different VSANS on the same interface.  So I have a single VFC bound to an interface, now can I assign 2 differen vsans to that vfc?

Yes, you can, if your devices connected to the N5K support VSAN trunking.  Just use the command switchport trunk allowed vsan xxx,yyy  to specify which VSANS should be allowed on the uplinks.

But when I try to add it to the vsan database with the following commands it only take the last one entered.

For example:

vsan database

  vsan 500 interface vfc3130

I can't do:

vsan database

  vsan 500 interface vfc3130

  vsan 600 interface vfc3130

Only the vsan 600 to vfc3130 will show.

A interface can only be assigned a single VSAN; however, if this interface supports trunking, multiple vsan tagged frames can be sent over this interface.
