Line Description
Loss of Signal Indicates if the interface has detected the required number of digital bit transitions
(from 1 to 0 and 0 to 1) on the incoming signal. A 10 GE link must detect a certain
number of such transitions for proper synchronization.
Rx Signal Lock Error Indicates a loss of timing condition. The receive clock must be recovered from the
incoming data stream to allow the receiving physical layer to synchronize with the
incoming electrical pulses.
PCS Link State
Display the state of the PCS (Physical Coding sub-layer). The state is either up or down.
Link Fault Remote. Indicates if the remote device has detected a fault, is inhibiting transmission of
frames, and may be continuously transmitting idle messages.
Link Fault Local. Indicates if a local fault is detected that may inhibit transmission of frames, and
may be continuously transmitting remote fault signals.
Link Fault Idle Error Indicates the detections of a non-idle symbol during an idle period.
Link Fault Illegal Symbol Indicates the detections of an illegal symbol, other than an error symbol, while
receiving data frames.
Link Fault Error Symbol. Indicates the detections of an error symbol while receiving data frames.
