On my shiny new M120 running 8.5 I have this "PIC-Peer" interface 
which was transmitting ~6000 pps / ~30 Mbps until I changed something 
in the config (not sure what caused it to stop--I can probably go back 
and correlate the time on the graph to the log in the router to see 
what changed).  Now as you can see, it is doing very little traffic.  
What is this interface for and why was it pushing so much traffic?
