[j-nsp] pfe-x/x/x and pfh-a/a/a

[Thomas Eichhorn]

Dear all,

I just saw some interfaces named
pfe- and pfh- on a trio based
MX960:

teichhorn at R10-et> show interfaces pfh-7/0/0
Physical interface: pfh-7/0/0, Enabled, Physical link is Up
   Interface index: 135, SNMP ifIndex: 549
   Speed: 800mbps
   Device flags   : Present Running
   Link flags     : None
   Last flapped   : Never
     Input packets : 0
     Output packets: 0

   Logical interface pfh-7/0/0.16383 (Index 328) (SNMP ifIndex 552)
     Flags: SNMP-Traps Encapsulation: ENET2
     Bandwidth: 0
     Input packets : 0
     Output packets: 0
     Protocol inet, MTU: Unlimited

   Interface index: 136, SNMP ifIndex: 550
   Speed: 800mbps
   Device flags   : Present Running
   Link flags     : None
   Last flapped   : Never
     Input packets : 0
     Output packets: 0

   Logical interface pfe-7/0/0.16383 (Index 327) (SNMP ifIndex 553)

     Bandwidth: 0
     Input packets : 0
     Output packets: 0

     Protocol inet6, MTU: Unlimited

My best guess would be that pfe-x/x/x has something to do
with the pfe, but pfh is completely unclear...

Has someone here a little bit more information about the purpose
of these ifaces?

Thanks,
Tom
