[j-nsp] Implementing Ethernet Aggregated Features

Hash: SHA1

fxp1 is the internal connection between the RE and the PFE.  You have no
access to that interface and should not *under any circumstances* change the
configuration of that interface.  Doing so will stop the router from
communicating between the RE and the PFE - so no forwarding of packets!
