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 quality of the channel based on the channel utilization. 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-toNoise 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: 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. 977| show ap arm rf-summary Dell Networking W-Series ArubaOS 6.5.x | Reference Guide
