Not true. 7401 has a PXF. It's essentially an NSE-1 with GE/IO in a pizza box. 7301 is based on the NPE-G1 and doesn't have a PXF anywhere in sight.
OK, more precisely (I did refer to the release notes of 12.2(20)S in my previous email) the 7304 is a PXF platform when using a NSE-100. The 7304 can be used with either a NPE-G100 (stated as 1M PPS, 3xGE) or NSE-100 (stated as 3.5M PPS by PXF, 450k PPS non-PXF, 2xGE). Of the PXF platforms: NSE-1 263MHz RM7000 "100MHz PXF" NSE-100 350MHz RM7000 "3.5M PPS PXF" 7401ASR 375MHz RM7000 "PXF based on NSE-1" The NSE-100 is a faster version of the NSE-1, and probably faster than the 7401ASR. Not clear if all the PXF based performance is equal or not between the three platforms; the 7401ASRs describe their PXF as "tmc type TMC ASIC revision 2". David.
