Description
Number of a radio channel used by the AP.
Number of 802.11 retry frames sent because a client failed to send an ACK.
Number of PHY errors on the AP's current channel seen during the last second.
Number of MAC errors on the AP's current channel seen during the last second.
Current noise level, in -dBm.
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.
The AP uses this metric to measure co-channel and adjacent channel interference. The
Interference Index is calculated as a/b//c/d, where:
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
l
channel.
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".
l
Name of the fastethernet or gigabit Ethernet interface
Current channels assigned by the AP's ARM profile.
Ideal value of coverage index an AP tries to achieve on its channel.
Number of channels that are currently being used by an AP's BSSIDs.
Number of channels that are available to an AP because that channel has a lower
interference index.
If enabled, ARM-enabled APs on the network edge will not become Air Monitors.
Time elapsed since the AP checked its channel and power settings, in
hour:minute:second format.
Time elapsed since the AP changed its channel and power settings, in
hour:minute:second format.
