Release Information

Statement introduced in Junos OS Release 13.2 for MX 3D Series routers.

Statement introduced in Junos OS Release 14.2 for EX Series switches.

Support for logical systems on MX Series routers added in Junos OS Release 17.4R1.

Description

Trace traffic flowing through an EVPN routing instance.

Options

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 the maximum size as specified by the size option, it is renamed trace-file.0. When trace-file again reaches the 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 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. You can specify the following tracing flags:

  • all—All EVPN tracing options

  • error—Error conditions

  • general—General events

  • mac-database—MAC route database in the EVPN routing instance

  • nlri—EVPN advertisements received or sent by means of BGP

  • normal—Normal events

  • oam—OAM messages

  • policy—Policy processing

  • route—Routing information

  • state—State transitions

  • task—Routing protocol task processing

  • timer—Routing protocol timer processing

  • topology—EVPN topology changes caused by reconfiguration or advertisements received from other provider edge (PE) routers using BGP

flag-modifier—(Optional) Modifier for the tracing flag. You can specify the following modifiers:

  • detail—Provide detailed trace information.

  • disable—Disable this trace flag.

  • receive—Trace received packets.

  • send—Trace sent packets.

no-world-readable—Do not allow any user to read the log 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 the 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 (as specified by the files option) 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—Allow any user to read the log file.

Required Privilege Level
