frames may be dropped even if the SVLAN says to forward them. Frames might also be
dropped if they are sent to a CPE (customer premises equipment) DSL device that does
not accept tagged frames.
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

the frame, it won’t check the port filter.
