show ap spectrum channel-summary
show ap spectrum channel-summary {ap-name
Description
This command displays a summary of the 802.11a or 802.11g channels seen by a spectrum monitor.
Parameter |
Description |
ap-name |
Name of the spectrum monitor for which you want to view spectrum information. |
ip-addr |
IP address of the spectrum monitor for which you want to view spectrum information. |
ip6-addr |
IPv6 address of the spectrum monitor for which you want to view spectrum information. |
freq-band {2.4ghz | 5ghz} |
View information for a specific radio type, either 2.4 GHz or 5 GHz. |
freq-band {2.4ghz | 5ghz | 6ghz}
|
View information for a specific radio type, either 2.4 GHz, 5 GHz, or 6 GHz. The 6ghz sub-parameter is applicable to Wi-Fi 6E APs only. |
The output of the 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.
A hybrid AP on a 20 MHz channel will see 40 MHz Wi-Fi data as non- Wi-Fi data.

The output of this command includes the following information:
Column |
Description |
Channel |
An 802.11a or 802.11g radio channel. |
Known APs |
Number of valid APs identified on the radio channel. |
UnKnown APs |
Number of invalid or rogue APs identified on the radio channel. |
Channel Util (%) |
Percentage of the channel currently in use. |
Max AP Signal (dBm) |
Signal strength of the AP that has the maximum signal strength on a channel. |
Max Interference(dBm) |
Signal strength of the non- Wi-Fi device that has the highest signal strength. |
SNIR (db) |
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. |
