Juniper EX3400 Features Guide

• main—Trace main loop events
• port—Trace arbitrary protocol events
• rtsock—Trace routing socket operations
• tftp—Trace TFTP service events
• trace—Trace tracing operations
• ui—Trace user interface operations
• util—Trace miscellaneous utility operations
match regular-expression—(Optional) Refine the output to include lines that contain the
regular expression.
no-remote-trace—(Optional) Disable remote tracing globally or for a specific tracing
operation.
no-world-readable—(Optional) Restrict file access to the owner.
size size—(Optional) Maximum size of each trace file, in kilobytes (KB), megabytes (MB),
or gigabytes (GB). When a trace file named trace-file reaches this size, it is renamed
trace-file.0. When the trace-file file again reaches its maximum size, trace-file.0 is
renamed trace-file.1 and trace-file is renamed trace-file.0. This renaming scheme
continues until the maximum number of trace files is reached. Then the oldest trace
file is overwritten.
If you specify a maximum file size, you also must specify a maximum number of trace
files with the files option and filename.
Syntax: xk to specify KB, xm to specify MB, or xg to specify GB
Range: 0 bytes through 4,294,967,295 KB
Default: 128 KB
world-readable—(Optional) Enable unrestricted file access.
