Parameter

Description

channel

Number of a radio channel used by the AP.

retry

Number of 802.11802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. 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 MACMedia Access Control. A MAC address is a unique identifier assigned to network interfaces for communications on a network. errors on the AP’s current channel seen during the last second.

noise

Current noise level, in -dBmDecibel-Milliwatts. dBm is a logarithmic measurement (integer) that is typically used in place of mW to represent receive-power level. AMP normalizes all signals to dBm, so that it is easy to evaluate performance between various vendors..

util(Qual)

The quality of the channel based on the channel utilization.

cov-idx

The AP uses this metric to measure RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. coverage. The coverage index is calculated as x+y, where “x” is the AP’s weighted calculation of the Signal-to-Noise Ratio (SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise.) on all valid APs on a specified 802.11802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. channel, and “y” is the weighted calculation of the Aruba APs SNRSignal-to-Noise Ratio. SNR is used for comparing the level of a desired signal with the level of background noise. 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:

Metric value “a” is the channel interference the AP sees on its selected channel.

Metric value “b” is the interference the AP sees on the adjacent channel.

Metric value “c” is the channel interference the AP’s neighbors see on the selected channel.

Metric value “d” is the interference the AP’s neighbors see on the adjacent channel.

To calculate the total Interference Index for a channel add “a+b+c+d”.

Interface Name

Name of the gigabit EthernetEthernet is a network protocol for data transmission over LAN. interface

Current ARM Assignment

Current channels assigned by the AP’s ARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. 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 BSSIDsBasic Service Set Identifier. The BSSID identifies a particular BSS within an area. In infrastructure BSS networks, the BSSID is the MAC address of the AP. In independent BSS or ad hoc networks, the BSSID is generated randomly..

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, ARMAdaptive Radio Management. ARM dynamically monitors and adjusts the network to ensure that all users are allowed ready access. It enables full utilization of the available spectrum to support maximum number of users by intelligently choosing the best RF channel and transmit power for APs in their current RF environment. -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.
