CoPilot Adverse Traffic Patterns Widget

This widget displays anomalies caused by TX and RX traffic loads that result in high resource use of multicast and broadcast communications. Use of multicast and broadcast requires devices to clone packets, which reduces CPU availability. This is usually not a problem unless the traffic load begins to overtake the available CPU capacity, which can increase latency and packet loss and might even bring a device down. The CPU threshold for APs is 90%. The CPU threshold for switches is 50%. The following data is displayed for active devices:

• Maximum and average CPU usage over time for wired and wireless devices.
• TX and RX unicast, multicast, and broadcast byte counts over time for backhaul interfaces on wired and wireless devices.
  

  Note

  Multicast information is not available for wireless devices, since they use unicast or broadcast only.
