Tracing RSVP Protocol Traffic
To trace RSVP protocol traffic, include the traceoptions statement:
You can include this statement at the following hierarchy levels:
- [edit protocols rsvp]
- [edit logical-systems logical-system-name protocols rsvp]
You can specify the following RSVP-specific flags in the RSVP traceoptions statement:
Use the file statement to specify the name of the file that receives the output of the tracing operation. All files are placed in the directory /var/log. We recommend that you place RSVP tracing output in the file rsvp-log.
- all—All tracing operations.
- error—All detected error conditions
- event—RSVP-related events (helps to trace events related to RSVP graceful restart)
- lmp—RSVP-Link Management Protocol (LMP) interactions
- packets—All RSVP packets
- path—All path messages
- pathtear—PathTear messages
- resv—Resv messages
- resvtear—ResvTear messages
- route—Routing information
- state—Session state transitions, including when RSVP-signaled LSPs come up and go down.
To view the log file generated when you enable RSVP traceoptions, issue the show log file-name command, where file-name is the file you specified using the traceoptions statement.
For general information about tracing and global tracing options, see the Junos OS Routing Protocols Library for Routing Devices.

RSVP Log File Output
The following is sample output generated by issuing the show log file-name command on a router on which RSVP traceoptions have been enabled with the state flag configured. The RSVP-signaled LSP E-D is shown being torn down on Mar 11 14:04:36.707092. On Mar 11 14:05:30.101492, it is shown coming back up.
