traceoptions (IGMP Snooping)

Syntax

Hierarchy Level

Release Information

Statement introduced in Junos OS Release 11.1 for the QFX Series.

Description

Define tracing operations for IGMP snooping.

Default

The traceoptions feature is 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.

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

• all—All tracing operations.
• general—Trace general IGMP snooping protocol events.
• krt—Trace communication over routing sockets.
• nexthop— Trace next-hop related events.
• normal—Trace normal IGMP snooping protocol events.
• packets—Trace all IGMP packets.
• policy—Trace policy processing.
• query—Trace IGMP membership query messages.
• report—Trace membership report messages.
• route—Trace routing information.
• state—Trace IGMP state transitions.
• task—Trace routing protocol task processing.
• timer—Trace routing protocol timer processing.
• vlan—Trace VLAN related events.

no-stamp—(Optional) Do not time stamp trace file.

no-world-readable—(Optional) Restrict file access to the user who created the 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 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. Use xk to specify KB, xm to specify MB, or xg to specify gigabytes.

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