The dotted red line is the MaxBytes[] value for the circuit.  It will 
appear on the graph when the volume of traffic exceeds roughly 95% of
MaxBytes[].

It, also, appears when you use AbsMax[] in conjunction with MaxBytes[].  
On frame relay circuits, I set AbsMax[] to the tail circuit speed which 
is, in my case, typically a T-1 circuit.  I use MaxBytes[] for the CIR.
