Dear all,

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

teichhorn@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

teichhorn@R10-et> show interfaces pfe-7/0/0
Physical interface: pfe-7/0/0, Enabled, Physical link is Up
  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)
    Flags: SNMP-Traps Encapsulation: ENET2
    Bandwidth: 0
    Input packets : 0
    Output packets: 0
    Protocol inet, MTU: Unlimited
    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
