traceoptions (LACP)

 

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 7.6.

Statement introduced in Junos OS Release 15.1F4 for PTX Series routers.

Description

Define tracing operations for the LACP protocol.

Default

If you do not include this statement, no LACP protocol tracing operations are performed.

Options

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, interface process tracing output is placed in the file lacpd.

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

Default: 3 files

flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements. You can include the following flags:

  • all—All LACP tracing operations

  • configuration—Configuration code

  • packet—Packets sent and received

  • process—LACP process events

  • protocol—LACP protocol state machine

  • routing-socket—Routing socket events

  • startup—Process startup events

no-world-readable—(Optional) Prevent any user from reading 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 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:

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 router

Default: 1 MB

world-readable—(Optional) Allow any user to read the log file.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
