Dell PowerConnect ArubaOS 6.0 Command Line Interface | Reference Guide show ap arm rf-summary | 524
Command History
Introduced in ArubaOS 3.0.
Command Information
retry Number of 802.11 retry frames sent because a client failed to send an ACK.
low-speed Number of frames sent at a data rate of 18 Mbps or slower.
non-unicast The number of non-unicast frames sent on the channel.
frag Number of fragmented packets
bwidth Current bandwidth, in kbps.
phy-err Number of PHY errors on the channel.
mac-err Number of MAC errors on the channel.
noise Current noise level, in -dBm.
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:
z Metric value “a” is the channel interference the AP sees on its selected channel.
z Metric value “b” is the interference the AP sees on the adjacent channel.
z Metric value “c” is the channel interference the AP’s neighbors see on the selected
channel.
z Metric value “d” is the interference the AP’s neighbors see on the adjacent channel
z 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.
ARM Edge State If enabled, ARM-enabled APs on the network edge will not become Air Monitors.
Last check channel/
pwr
Time elapsed since the AP checked its channel and power settings, in hour:minute:second
format.
Last change channel/
pwr
Time elapsed since the AP changed its channel and power settings, in hour:minute:second
format.
