show ap spectrum channel-metrics show ap spectrum channel-metrics {ap-name }|{ip-addr } freq-band 2.4ghz|5ghz Description This command shows channel quality, availability and utilization metrics as seen by a spectrum monitor. Syntax Parameter ap-name Description Name of the spectrum monitor for which you want to view spectrum information. ip-addr IP address of the spectrum monitor. freq-band 2.4ghz|5ghz View information for a specific radio type, either 2.4 GHz or 5 GHz. Usage Guideline This chart displays channel utilization data, showing the percentage of each channel that is currently being used by Wi-Fi devices, and the percentage of each channel being used by non-Wi-Fi devices and 802.11 adjacent channel interference (ACI). ACI refers to the interference on a channel created by a transmitter operating in an adjacent channel. A transmitter on a nonadjacent or partially overlapping channel may also cause interference, depending on the transmit power of the interfering transmitter and/or the distance between the devices. In general, ACI may be caused by a Wi-Fi transmitter or a non-Wi-Fi interferer. However, whenever the term ACI appears in Spectrum Analysis graphs, it refers to the ACI caused by Wi-Fi transmitters. The channel utilization option in the Channel Metrics Chart shows the percentage of the channel utilization due to both ACI and non-Wi-Fi interfering devices. Unlike the ACI shown in the show ap spectrum interference-power output, the ACI shown in this graph indicates the percentage of channel time that is occupied by ACI or unavailable for Wi-Fi communication due to ACI. The Channel Metrics table can also show channel availability, the percentage of each channel that is available for use, or display the current relative quality of selected channels in the 2.4 GHz or 5 GHz radio bands. In the spectrum analysis feature, channel quality is a relative measure that indicates the ability of the channel to support reliable Wi-Fi communication. Channel quality, which is represented as a percentage in this chart, is a weighted metric derived from key parameters that can affect the communication quality of a wireless channel, including noise, non-Wi-Fi (interferer) utilization and duty-cycles, and certain types of retries. Note that channel quality is not directly related to Wi-Fi channel utilization, as a higher quality channel may or may not be highly utilized. A hybrid AP on a 20 MHz channel will see 40 MHz Wi-Fi data as non-Wi-Fi data. Examples The output of this example shows part of the channel metrics table for channels seen by the spectrum monitor ap123.

show ap spectrum channel-metrics

show ap spectrum channel-metrics {ap-name <ap-name>}|{ip-addr <ip-addr>} freq-band 2.4ghz|5ghz

Description

This command shows channel quality, availability and utilization metrics as seen by a spectrum monitor.

Syntax

Parameter

Description

ap-name <ap-name>

Name of the spectrum monitor for which you want to view spectrum

information.

ip-addr <ip-addr>

IP address of the spectrum monitor.

freq-band 2.4ghz|5ghz

View information for a specific radio type, either 2.4 GHz or 5 GHz.

Usage Guideline

This chart displays channel utilization data, showing the percentage of each channel that is currently being used

by Wi-Fi devices, and the percentage of each channel being used by non-Wi-Fi devices and 802.11 adjacent

channel interference (ACI).

ACI refers to the interference on a channel created by a transmitter operating in an adjacent channel. A transmitter

on a nonadjacent or partially overlapping channel may also cause interference, depending on the transmit power of

the interfering transmitter and/or the distance between the devices. In general, ACI may be caused by a Wi-Fi

transmitter or a non-Wi-Fi interferer. However, whenever the term ACI appears in Spectrum Analysis graphs, it

refers to the ACI caused by Wi-Fi transmitters. The channel utilization option in the Channel Metrics Chart shows the

percentage of the channel utilization due to both ACI and non-Wi-Fi interfering devices. Unlike the ACI shown in the

show

spectrum

interference-

power

output, the ACI shown in this graph indicates the percentage of channel time

that is occupied by ACI or unavailable for Wi-Fi communication due to ACI.

The Channel Metrics table can also show channel availability, the percentage of each channel that is available

for use, or display the current relative quality of selected channels in the 2.4 GHz or 5 GHz radio bands. In the

spectrum analysis feature, channel quality is a relative measure that indicates the ability of the channel to

support reliable Wi-Fi communication. Channel quality, which is represented as a percentage in this chart, is a

weighted metric derived from key parameters that can affect the communication quality of a wireless channel,

including noise, non-Wi-Fi (interferer) utilization and duty-cycles, and certain types of retries. Note that channel

quality is not directly related to Wi-Fi channel utilization, as a higher quality channel may or may not be highly

utilized.

A hybrid AP on a 20 MHz channel will see 40 MHz Wi-Fi data as non-Wi-Fi data.

Examples
