CoPilot Port Efficiency Widget

This widget identifies wired and wireless device interfaces that are not making efficient use of their uplink backhaul connection. This can happen in a number of ways:

• An interface might only use half-duplex communication, that is, just 50% of the available throughput capacity.
• An interface can occasionally flip between full-duplex and half-duplex modes. If this happens too often, it indicates that the interface cannot maintain a full-duplex connection and is considered an anomaly.
• An interface might use an inefficient data rate relative to its capability. Allowable data rates are 10 Mbps, 100 Mbps, 1000 Mbps, and 2500 Mbps. Data rates of 10 Mbps or 100 Mbps are considered inefficient. 1000 Mbps and 2500 Mbps usage rates are considered normal.
• An interface might occasionally flip between data rates, for example, from 2500 Mbps to 1000 Mbps. When this happens on a regular basis, it indicates that there is a wider issue preventing the interface from maintaining the higher data rate.
