What happened ? PXF is found in the 7400 (old) and 7300 (newer) series. The 7400 was extremely unstable until very recently (with 12.2(14)S5 it is quite stable, as long as you have the hardware with the fixed L3 cache or have the L3 cache disabled), which is perhaps why PXF was not pushed so heavily after that experience. I have not used a 7300. If you want to look at what features they are pushing into PXF on them, look at the 12.2(20)S release notes. After the pain of being an early adopter of the 7400 I'm staying well away from the 7300 until I see others using them without stability issues. 7400 is closely related to the NPE400 (actually NSE-1), 7300 is closely related to the NPE-G1.
