traceoptions

Syntax

traceoptions {file filename <files number> <size maximum-file-size> <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 in Release 8.5 of Junos OS.

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

error—Errored ES-IS packets

esh—End-System hello packets

graceful-restart—Graceful restart events

ish—Intermediate-System hello packets

Global Tracing Flags

all—All tracing operations

general—A combination of the normal and route trace operations

normal—All normal operations, including adjacency changes

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

policy—Policy operations and actions

route—Routing table changes

state—State transitions

task—Interface transactions and processing

timer—Timer usage

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

detail—Detailed trace information

receive—Packets being received

send—Packets being transmitted

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

size maximum-file-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.
