Delete Vlan Id; Enable Vlan - ZyXEL Communications ZyXEL Dimension ES-2048 User Manual

ES-2048 User's Guide
3 The switch notes what the SVLAN table says (that is, the SVLAN tells the switch
whether or not to forward a frame and if the forwarded frames should have tags).
4 Then the switch applies the port filter to finish the forwarding decision. This means that
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.
35.3.4.2.2 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.
