Sometimes you may need to have some additional interface statistics, for example the amount of packets per range of sizes. You can use netflow to collect some stats like these. But if you don't have netflow on all your router interfaces or for troubleshooting purposes you need sometimes to quickly check packet size stats : You can use PFE commands.
Each PFE command has been tested several times and I never encountered issue with these one. But As I already said in a previous post : PFE commands are not supported by JTAC : so be careful. (expecially with a new Junos version - try before in lab ;-)
Each type of card has its own PFE command to collect Interface statistics. Let's start with the MX series.
1/ MX series - Ichip based card
For DPCE 40x1GE or 4x10GE or combo cards
start shell pfe network fpcN # N = FPC slot
# X = PIC slot ; Y = Port slot ex. xe-N/X/Y
show xeth-pic X port Y stats
