Release Information

Statement introduced before JUNOS Release 7.4.

Description

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

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, VRRP 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. When the maximum number is reached, 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.
flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. These are the VRRP-specific tracing options:
match regex—(Optional) Refine the output to include only those lines that match the given regular expression.
microsecond-stamp—(Optional) Provide a timestamp with microsecond granularity.
size size—(Optional) Maximum size of each trace file, in kilobytes, megabytes, or gigabytes. 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.
world-readable | no-world-readable—Specifies whether any reader can read the log file.
