Chapter 34 IEEE 802.1Q Tagged VLAN Commands

Untagged Frames

1An untagged frame comes in from the LAN.

2The switch checks the PVID table and assigns a temporary VID of 1.

3The 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.

4If 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.
