400 CHAPTER 10: MONITORING THE NETWORK
Using the RF Trends
Window
The RF Trends window shows current and past 802.11 statistics for
radios. You can view statistics up to 30 days old, and display graphs of
data trends.
PHY Packet Errors Number of frames received by the MAP radio that had
physical layer errors on the active channel. These errors
can indicate interference from a non-802.11 device.
Pkt Re-transmissions Number of retransmitted packets sent from the client to
the radio on the active channel. Retransmissions can
indicate that the client is not receiving ACKs from the MAP
radio.
Utilization Number of multicast packets per second that a radio can
send on a channel while continuously sending fixed size
frames over a period of time. The number of packets that
are successfully transmitted indicates how busy the
channel is.
