Inbound no, outbound yes. If the VLAN doesn't exist there is no
spanning-tree instance, and there will no MAC entries in the CAM table
for that VLAN. Therefore the switch can receive the traffic but can't
forward it on. As a general rule make sure that all VLANs you are using
exist in the database either via VTP or manual configuration before
assigning them, SVI interfaces included.

Does a Cisco switch ( 3560) have to know the vlan in it's database to
allow
it to be trunked?
