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”.
Interface Name
Name of the fastethernet or gigabit Ethernet interface
Current ARM Assignment
Current channels assigned by the AP’s ARM profile.
Target Coverage Index
Ideal value of coverage index an AP tries to achieve on its channel.
Covered channels a/g
Number of channels that are currently being used by an AP’s BSSIDs.
Free channels a/g
Number of channels that are available to an AP because that channel has a
lower interference index.
