Release Information

Statement introduced before JUNOS Release 7.4.

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Description

Define tracing operations that track all routing protocol functionality in the routing device.

To specify more than one tracing operation, include multiple flag statements.

Default

If you do not include this statement, no global tracing operations are performed.

Options

Values:

disable—(Optional) Disable the tracing operation. You can use this option to disable a single operation when you have defined a broad group of tracing operations, such as all.

file filename—Name of the file to receive the output of the tracing operation. Enclose the name within quotation marks. All files are placed in the directory /var/log. We recommend that you place global routing protocol tracing output in the file routing-log.

files number—(Optional) Maximum number of trace files. When a trace file named trace-file reaches its maximum size, it is renamed trace-file.0, then trace-file.1, and so on, until the maximum number of trace files is reached. Then, the oldest trace file is overwritten. Note that if you specify a maximum number of files, you also must specify a maximum file size with the size option.

Range: 2 through 1000 files

Default: 10 files

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. These are the global routing protocol tracing options:

all—All tracing operations
condition-manager—Condition-manager events
config-internal—Configuration internals
general—All normal operations and routing table changes (a combination of the normal and route trace operations)
graceful-restart—Graceful restart operations
normal—All normal operations
nsr-synchronization—Nonstop active routing synchronization
parse—Configuration parsing
policy—Routing policy operations and actions
regex-parse—Regular-expression parsing
route—Routing table changes
state—State transitions
task—Interface transactions and processing
timer—Timer usage

no-world-readable—(Optional) Prevent any user from reading the log file.

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 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. Note that if you specify a maximum file size, you also must specify a maximum number of trace files with the files option.

Syntax: xk to specify KB, xm to specify MB, or xg to specify GB

Range: 10 KB through the maximum file size supported on your system

Default: 128 KB

world-readable—(Optional) Allow any user to read the log file.

Required Privilege Level

routing and trace—To view this statement in the configuration.

routing-control and trace-control—To add this statement to the configuration.
