Hi there, On a recently T1 PtP deployment, I noticed that one end is getting a high number of ³Total output drops². 51 in the last 24 minutes. No other errors or abnormalities on this one side, and the other side is at 0.
What could cause this? My T1 debugging skills are still in novice mode. Is this something that I need to be concerned with or am I overly paranoid? Currently, not a ³whole lot of² traffic is going over this link; but I did setup the QoS for that ³just incase².
