Description

Configure BGP protocol-level tracing options.

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

Default

The default BGP protocol-level tracing options are inherited from the routing protocols traceoptions statement included at the [edit routing-options] hierarchy level. The default group-level trace options are inherited from the BGP protocol-level traceoptions statement. The default peer-level trace options are inherited from the group-level traceoptions statement.

Options

disable—(Optional) Disable the tracing operation. You can use this option is 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 BGP tracing output in the file bgp-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 must also 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 tracing operation, include multiple flag statements.

BGP Tracing Flags

• as-path—AS path regular expression operations.
• damping—Damping operations.
• keepalive—BGP keepalive messages.
• open—Open packets. These packets are sent between peers when they are establishing a connection.
• packets—All BGP protocol packets.
• update—Update packets. These packets provide routing updates to BGP systems.

Global Tracing Flags

• all—All tracing operations.
• general—A combination of the normal and route trace operations.
• normal—All normal operations.
  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—Provide detailed trace information.
• filter—Filter trace information. Applies only for route and damping tracing flags.
• receive—Packets being received.
• send—Packets being transmitted.

no-stamp—(Optional) Do not place timestamp information at the beginning of each line in the trace file.
Default: If you omit this option, timestamp information is placed at the beginning of each line of the tracing output.

no-world-readable—(Optional) Disallow any user to read the log file.

replace—(Optional) Replace an existing trace file if there is one.
Default: If you do not include this option, tracing output is appended to an existing trace 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: 1 MB

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