[j-nsp] 10 port GigE SFP PIC

[Lev Garantin]

Hello,

looking at the following page, I have a couple questions.
 
http://www.juniper.net/techpubs/hardware/m320/m320-pic/gigabit-ethernet-sfp.html

I'm not sure what to make of
  "The 10-port Gigabit Ethernet PIC with SFP does not support MAC
   accounting and policing, MAC learning, TPID, or flexible Ethernet
   encapsulation."

"no MAC learning" as in "no ARP"?

And does this PIC have a full 1Gbit/s bandwidth available per port into
the router or is there some kind of oversubscription happening (given a
FPC3)?

Thanks in advance and kind regards, Lev
