The sample output is for an OC-12 ATM interface and shows the statistics for the SONET media, as well as the
InputandOutputATM errors. Error details include input and output errors, active alarms and defects, and media-specific errors.If the physical link is down, look at the active alarms and defects for the ATM interface and check the ATM media accordingly. See Locate ATM Alarms and Errors for an explanation of ATM alarms.
