Untagged Frames
1 An untagged frame comes in from the LAN.
2 The switch checks the PVID table and assigns a temporary VID of 1.
3 The switch ignores the port from which the frame came, because the switch does not
send a frame to the port from which it came. The switch also does not forward frames to
“forbidden” ports.
4 If after looking at the SVLAN, the switch does not have any ports to which it will send
the frame, it won’t check the port filter.
