traceoptions (Protocols Layer 2 VPN)
Statement introduced before Junos OS Release 7.4.
Trace traffic flowing through a Layer 2 VPN.
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 filename—Name of the file to receive the output of the tracing operation. Enclose the name in quotation marks (" ").
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 1000 files
Default: 2 files
flag flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements.
all—All Layer 2 VPN tracing options
connections—Layer 2 connections (events and state changes)
nlri—Layer 2 advertisements received or sent by means of the BGP
task—Routing protocol task processing
timer—Routing protocol timer processing
topology—Layer 2 VPN topology changes caused by reconfiguration or advertisements received from other PE routers using BGP
flag-modifier—(Optional) Modifier for the tracing flag. You can specify the following modifier:
detail—Provide detailed trace information
receive—Trace received packets
send—Trace transmitted packets
no-world-readable—(Optional) Prevents any user from reading the 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 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 kilobytes, xm to specify megabytes, or xg to specify gigabytes
Range: 10 KB through the maximum file size supported on your system
Default: 1 MB
world-readable—(Optional) Allow any user to read the trace file.
Default: The default is no-world-readable.
