    Hierarchy Level

    Release Information

    Statement introduced before Junos OS Release 7.4.

    graceful-restart flag for IS-IS and OSPF/OSPFv3 added in Junos OS Release 8.4.

    Description

    Define tracing operations that graceful restart functionality in the router or switch.

    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

    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 name—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.

    Range: 2 through 1000 files

    Default: 2 files

    If you specify a maximum number of files, you also must specify a maximum file size with the size option.

    flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. The nonstop active routing tracing option is:

    • graceful-restart—Tracing operations for nonstop active routing

    no-world-readable—Restrict users 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.

    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

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

    world-readable—Allow users 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.
