The system detects and corrects single-bit errors, then logs the event in the /var/log/eccd file.

Page 653: Chapter 47 Monitoring Redundant Cfebs
Chapter 47 Monitoring Redundant CFEBs You monitor redundant Compact Forwarding Engine Boards (CFEBs) in the M10i router. A CFEB provides route lookup, filtering, and switching on incoming data packets, then directs outbound packets to the appropriate interface for transmission to the network. (See Table 129.) The M10i router CFEB can process 16 million packets per second (Mpps).

The CLI indents each level in the hierarchy to indicate each statement’s relative position in the hierarchy and generally sets off each level with braces, using an open brace at the beginning of each hierarchy level and a closing brace at the end.
Page 685: Modifying The Configuration
Appendix A: Command-Line Interface Overview Modifying the Configuration To configure the router or to modify an existing router configuration, you add statements to the configuration.
