The output of this command includes the following information:
Parameter Description
channel
Number of a radio channel used by the AP.
retry
Number of 802.11 retry frames sent because a client failed to send an ACK.
phy-err
Number of PHY errors on the AP’s current channel seen during the last
second.
mac-err
Number of MAC errors on the AP’s current channel seen during the last
second.
noise
Current noise level, in -dBm.
util(Qual)
The quality of the channel based on the channel utilization.
cov-idx
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 Dell APs SNR the neighboring APs see on
that channel.
intf_idx
The AP uses this metric to measure co-channel and adjacent channel
interference. The Interference Index is calculated as a/b//c/d, where:
l Metric value “a” is the channel interference the AP sees on its selected
channel.
l Metric value “b” is the interference the AP sees on the adjacent channel.
l Metric value “c” is the channel interference the AP’s neighbors see on
the selected channel.
l Metric value “d” is the interference the AP’s neighbors see on the
adjacent channel.
l To calculate the total Interference Index for a channel add “a+b+c+d”.
