Switches handling 802.1p without trunking

I need to know what Cisco switches will do with a non-trunked port recieving a 802.1p tag? Will the 4 extra bytes (802.1P) cause the frame to be rejected or will the switch read the 802.1P tag (asumming its a trusted port)? What switches will handle it and which will drop it?

If the port is in access-mode (not 802.1q trunk), then
if port is assigned to vlan (switchport access vlan N), then frame will have changed 802.1Q tag to this vlan
if port is not assigned to vlan, then the frame will have stripped 802.1q tag

And in fact, the above applies to any ethernet frame recived on such port.

Does it have to be trunked for the 802.1p tag to be honored?
ravenplCommented:
Yes, 1q tags set on ethernet frame is only honored(forwarded), when port is in trunking mode, and 1q tag match one of allowed VLANs on port, otherwise is rewrited to default vlan or the access mode vlan.
