Testing the RFPing

The "rfping" command provides information about the RF link between the WSS and the client based on sending test
packets to the client. The output of the command indicates the number of test packets received and acknowledged by the
client as well as the client's signal strength and signal-to-noise ratio. The command is executed from the CLI superuser
prompt.
To test the rfping
WSS# rfping mac {mac-addr} session-id {session-id}
WSS# rfping mac 00:09:2d:94:25:a9
RFPing to 00:09:2d:94:2 5:a9 :
Session-Id: 672

Feedback Explanation
Packets Sent The number of test packets sent from the WSS to the client.
Packets Received The number of test packets acknowledged by the client.
RSSI Received signal strength indication (RSSI) - the strength of the RF signal from the
client, in decibels referred to 1 milliwatt (dBm)
SNR Signal-to-noise ratio (SNR), in decibels (dB), of the data received from the client.
RTT (micro-secs) The round-trip time (RTT) in microseconds, for the client's response to the test
packets
