traceoptions

traceoptions (individual interfaces)

Syntax

traceoptions {
    flag flag <disable>;
}

Hierarchy Level

[edit interfaces interface-name]

Description

Define tracing operations for individual interfaces.

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

The interfaces traceoptions statement does not support a trace file. The logging is done by the kernel, so the tracing information is placed in the system syslog file in the directory /var/log.

Default

If you do not include this statement, no interface-specific 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.

flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. The following are the interface-specific tracing options.

• all—All interface tracing operations
• event—Interface events
• ipc—Interface IPC messages
• media—Interface media changes

Usage Guidelines

See Trace Operations of the Interface Process.

Required Privilege Level

interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.

traceoptions (interface process)

Syntax

traceoptions {
    file filename <size size> <files number>;
}

Hierarchy Level

[edit interfaces]

Description

Define tracing operations for the interface process (dcd).

Default

If you do not include this statement, no interface-specific tracing operations are performed.

Options

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. By default, interface process tracing output is placed in the file dcd.

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 1,000
Default: 3 files

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 router
Default: 1 MB

Usage Guidelines

See Trace Operations of the Interface Process.

Required Privilege Level

interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.

traceoptions (VRRP)

Syntax

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

Hierarchy Level

[edit protocols vrrp]

Description

Define tracing operations for Virtual Router Redundancy Protocol (VRRP).

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

By default, VRRP logs the error, dcd configuration, and routing socket events in a file in the directory /var/log.

Default

If you do not include this statement, no VRRP-specific tracing operations are performed.

Options

filename 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. By default, interface process tracing output is placed in the file vrrpd.

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 1,000
Default: 3 files

flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. These are the VRRP-specific tracing options.

• all—All VRRP tracing operations
• database—Database changes
• general—General events
• interfaces—Interface changes
• normal—Normal events
• packets—Packets sent and received
• state—State transitions
• timer—Timer events

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 router
Default: 1 MB

world-readable | no-world-readable—Specifies whether any reader can read the log file.
