monitor stop
Sample Output
The sample output shows real-time tracing information displayed on your computer screen (*** rsvp-log ***), and that display to the computer screen was started (monitor start) and then stopped (monitor stop). Even though you have stopped displaying log file entries on your screen, the tracing is still occurring on the router configured with trace options. The log file displays a Path message that was sent from R1 to R5, and another that R1 received from R5, indicating that the two unidirectional LSPs between R1 and R5 are established. For more information about Path messages, see Examining RSVP Log Messages.
If you stop monitoring to your screen and want to view the contents of the log file, use the show log filename command. For steps to view the log file, see View the RSVP Log File.
