traceoptions (Protocols VRRP)
Statement introduced before Junos OS Release 7.4.
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
If you do not include this statement, no VRRP-specific tracing operations are performed.
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
Maximum number of trace files. When a trace file named
trace-file reaches its maximum
size, it is renamed
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.
Range: 0 through 4,294,967,296 files
Default: 3 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. These are the VRRP-specific tracing options:
all—All VRRP tracing operations
packets—Packets sent and received
match regular-expression—(Optional) Refine the output to include only those lines that match the given regular expression.
microsecond-stamp—(Optional) Provide a timestamp with microsecond granularity.
no-world-readable—(Optional) Restrict users from reading the log file.
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 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 routing platform
Default: 1 MB
If you specify a maximum file size, you also must specify a maximum number of trace files with the files option.
world-readable—(Optional) Allow users to read the log file.
Required Privilege Level
trace—To view this statement in the configuration.
trace-control—To add this statement to the configuration.
