traceoptions

Syntax

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

Hierarchy Level

[edit protocols esis],
[edit routing-instances routing-instance-name protocols esis]

Release Information

Statement introduced before JUNOS Release 7.4.

Description

Configure ES-IS protocol-level tracing options.

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

Default

The default ES-IS protocol-level tracing options are those inherited from the routing protocols traceoptions statement included at the [edit routing-options] hierarchy level.

Options

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 ES-IS tracing output in the file esis-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.

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: 2 files

flag—Tracing operation to perform. To specify more than one flag, include multiple flag statements.

ES-IS Tracing Flags

Global Tracing Flags

Default: If you do not specify this option, only unusual or abnormal operations are traced.

flag-modifier—(Optional) Modifier for the tracing flag. You can specify one or more of these modifiers:

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.

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: Default: 1 MB

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