Description

Define tracing operations that gracefully restart functionality in the router. 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. (It’s recommended 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: 2–1,000 files. Default: two files.

Note

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

flag flag
