Tracing RSVP Protocol Traffic

To trace RSVP protocol traffic, include the traceoptions statement:

traceoptions { file filename <files number> <size size> <world-readable | no-world-readable>;flag flag <flag-modifier> <disable>; }

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

For general information about tracing and global tracing options, see the Junos Routing Protocols Configuration Guide.

Examples: Tracing RSVP Protocol Traffic

Trace RSVP path messages in detail:

[edit]protocols {rsvp {traceoptions {file rsvp size 10m files 5;flag path;}}}

Trace all RSVP messages:

[edit]protocols {rsvp {traceoptions {file rsvp size 10m files 5;flag packets;}}}

Trace all RSVP error conditions:

[edit]protocols {rsvp {traceoptions {file rsvp size 10m files 5;flag error;}}}
