29.5.4.2 Forwarding Process Example

Tagged Frames
1 First the switch checks the VLAN ID (VID) of tagged frames or assigns temporary VIDs
to untagged frames.
2 The switch then checks the VID in a frame's tag against the SVLAN table.
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).
