* The switch may decide not to pass the frame to the other port, based on its
learning.
** A priority-tagged frame (frame with a tag and VLAN-ID 0) is treated just like an
untagged frame. This includes rewriting the priority field with 0.
*** Learning is disabled; therefore, every frame is switched. The network port is
typically connected to another switch.
