Abstract
A method and apparatus for switching/bridging frames between a heterogeneous media is disclosed. Bridges and/or switches normally bit-swap a MAC header of a frame when switching the frame between heterogeneous media. However, this practice introduces errors in address formats in certain situations. Such problems are resolved by investigating whether a frame to be switched includes local address components, and if so, these address components in the frame are manipulated to ensure that the address formats are proper for a media onto which the frame is being switched.
