The output of this command includes the following information:
Column
Description
channel
Displays the list of channels enabled on an AP.
retry
Indicates the number of retry attempts.
Phy-err
Indicates the PHY errors on the current channels of an AP.
Mac-err
Indicates the MAC errors on the current channels of an AP.
noise
Displays the current noise level on each channel.
Util (Qual)
Displays the percentage of the channel being used and the current
relative quality of selected channels.
cov-idx(Total)
Displays RF coverage details. The AP uses this metric to measure RF
coverage. The coverage index is calculated as x+y, where “x” is the
AP’s weighted calculation of the Signal-to- Noise Ratio (SNR) on all
valid APs on a specified
802.11 channel, and “y” is the weighted calculation of the APs SNR
detected by the neighboring APs on that channel.
intf_idx(Total
Displays channel interference details. The AP uses this metric to
measure co- channel and adjacent channel interference. The Interfer-
ence Index is calculated as a/b//c/d, where:
• Metric value “a” is the channel interference the AP sees on its
selected channel.
• Metric value “b” is the interference the AP sees on the adjacent
channel.
• Metric value “c” is the channel interference the AP’s neighbors see
on the selected channel.
• Metric value “d” is the interference the AP’s neighbors see on the
adjacent channel.
• To calculate the total Interference Index for a channel add
“a+b+c+d”.
channel_pair
Displays the list of paired channels.
Pairwise_intf_index
Displays the pairwise interference index.
Interface Name
Displays the interface name.
Current ARM Assignment
Displays the current ARM assignment details.
Covered channels
Displays the number of channels being used by the AP's BSSID in the
2.4 GHz and 5 GHz bands.
Free channels
Displays the number of available channels in the 2.4 GHz and 5 GHz
bands.
ARM Edge State
Displays the ARM Edge status. If ARM edge status is enabled, the
ARM-enabled APs on the network edge will not function as Air Moni-
tors.
Last check channel/pwr
Indicates the time since the channel and power assignment was veri-
fied.
