I just noticed another odd one in regards to this. We have an ERX-SFP running as a switch at a small tower. It quit reporting throughput entirely around April 27. I'msuspecting that is when I updated it to 2.0.1. The web GUI, and all UNMS views just show zero traffic and it's currently passing about 20 Mbps. Below is the proof from UNMS. Which is odd because the routers exhibiting the problem in the OP do continue reporting to UNMS. Maybe this needs to be in a new thread? I put it here because it seems like it might help figure the problem out.
