traceoptions (Edge Virtual Bridging)

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 12.1 for EX Series switches.

Description

Define global tracing operations for edge virtual bridging (EVB) features on Ethernet switches.

Default

Tracing operations are disabled by default.

Options

file 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.

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 (xk to specify KB, xm to specify MB, or xg to specify gigabytes), at which point 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.

no-world-readable—(Optional) Restrict file access to the user who created the file.

replace—(Optional) Replace an existing trace file if there is one rather than appending output to it.

size size—(Optional) Maximum size of each trace file, in kilobytes (KB), megabytes (MB), or gigabytes. 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 files option.

world-readable—(Optional) Enable unrestricted file access.

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

• all—Trace everything.
• ecp—Trace Edge Control Protocol (ECP) events.
• evb-tlv— Trace EVB type, length, and value (TLV) events.
• parse—Trace configuration parsing.
• policy—Trace policy events.
• vdp—Trace Virtual Station Interface (VSI) Discovery and Configuration Protocol (VDP) events.

Required Privilege Level

system—To view this statement in the configuration.
system-control—To add this statement to the configuration.
