Monitoring SONET/SDH Interfaces
lockedOut Indicates that the router is configured to prevent the protect
interface from taking over if the primary interface fails
SD Indicates that signal degradation is detected
SF Indicates that signal failure is detected
switched Indicates that the router has switched from the working
interface to the protect interface
Counters Statistics for APS channel
SignalDegrades Number of degraded signals detected
SignalFailures Number of failed signals detected
Switchovers Number of times the router has switched from the working
interface to the protect interface
LastSwitchover Length of time that the working interface was active
when the router last switched from the working interface to the protect
interface; a value of Not Applicable indicates that no switchovers have
occurred
