1. A method comprising:
at a management entity configured to monitor a transceiver system having a transceiver to receive a signal that conveys data frames transmitted by a peer transceiver over a connection:
collecting time series values for operating parameters of the transceiver associated with received data frames, including (i) a receive power, and (ii) counts of different media access control (MAC) layer frame errors that respectively indicate degradation levels for system performance ranked from highest to lowest, wherein the different MAC layer frame errors include, in order of degradation level from highest to lowest, link resets and other types of MAC layer frame errors
using the time series values, performing correlations of the receive power against the counts of the different MAC layer frame errors according to a correlation hierarchy that indicates which of the correlations correspond to which of the degradation levels, to produce correlation results; and
responsive to the correlation results, determining a degraded component of the transceiver system.
