3.16.2 SRTB Usage in the ATX
The table below describes the results of the RIF; it does not take
into consideration frame translations. The translations will work
the same as before. For this table, it is assumed that a transparent
(TP) frame enters a TP configured port and a SR frame will enter a
SR port. Either a TP or SR frame can enter a port configured for
SRT.
