Column retry Phy-err Mac-err noise Util (Qual) cov-idx(Total) intf_idx(Total channel_pair Pairwise_intf_index Interface Name Current ARM Assignment Covered channels Free channels ARM Edge State Last check channel/pwr Description Indicates the number of retry attempts. Indicates the PHY errors on the current channels of a W-IAP. Indicates the MAC errors on the current channels of a W-IAP. Displays the current noise level on each channel. Displays the percentage of the channel being used and the current relative quality of selected channels. Displays RF coverage details. The W-IAP uses this metric to measure RF coverage. The coverage index is calculated as x+y, where "x" is the W-IAP'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 W-IAPs SNR detected by the neighboring APs on that channel. Displays channel interference details. The W-IAP 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". Displays the list of paired channels. Displays the pairwise interference index. Displays the interface name. Displays the current ARM assignment details. Displays the number of channels being used by the W-IAP's BSSID in the 2.4 GHz and 5 GHz bands. Displays the number of available channels in the 2.4 GHz and 5 GHz bands. Displays the ARM Edge status. If ARM edge status is enabled, the ARM-enabled W-IAPs on the network edge will not function as Air Monitors. Indicates the time since the channel and power assignment was verified. 258 | show ap arm Dell Networking W-Series Instant 6.4.3.1-4.2.0.0 | CLI Reference Guide

Column
Description
retry
Indicates the number of retry attempts.
Phy-err
Indicates the PHY errors on the current channels of a W-IAP.
Mac-err
Indicates the MAC errors on the current channels of a W-IAP.
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 W-IAP uses this metric to measure RF
coverage. The coverage index is calculated as x+y, where “x” is the W-IAP’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 W-IAPs SNR
detected by the neighboring APs on that channel.
intf_idx(Total
Displays channel interference details. The W-IAP 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”.
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 W-IAP'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
W-IAPs on the network edge will not function as Air Monitors.
Last check
channel/pwr
Indicates the time since the channel and power assignment was verified.
