Description
This command displays a summary of the 802.11a or 802.11g channels seen by a spectrum monitor.
Syntax
Parameter
ap-name <ap-name>
ip-addr <ip-addr>
freq-band
2.4ghz|5ghz
Usage Guidelines
This table can display data aggregate data for each channel seen by the spectrum monitor radio, including the
maximum AP power, interference and the signal-to-noise-and-interference Ratio (SNIR).
SNIR is the ratio of signal strength to the combined levels of interference and noise on that channel. This value is
calculated by determining the maximum noise-floor and interference-signal levels, and then calculating how strong
the desired signal is above this maximum.
NOTE: A hybrid AP on a 20 MHz channel will see 40 MHz Wi-Fi data as non-Wi-Fi data.
Examples
The output of the example below shows information for 802.11a radio channels seen by the spectrum monitor
ap999.
