Description
Configure Automatic Multicast Tunneling (AMT) tracing options.
To specify more than one tracing operation, include multiple flag statements.
Options
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 within quotation marks. All files are placed in the directory /var/log. We recommend that you place tracing output in the file igmp-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. Then the oldest trace file is overwritten.
If you specify a maximum number of files, you must also include
the size statement to specify the maximum file size.
Range: 2 through 1000 files
Default: 2 files
flag—Tracing operation
to perform. To specify more than one tracing operation, include multiple flag statements.
AMT Tracing Flags
errors—All error conditions
packets—All AMT packets
tunnels—All AMT tunnel-related information
Global Tracing Flags
all—All tracing operations
normal—All normal operations
Default: If you do not specify this option, only unusual or abnormal operations are traced.
policy—Policy operations and actions
route—Routing table changes
state—State transitions
task—Interface transactions and processing
timer—Timer usage
flag-modifier—(Optional) Modifier for the tracing flag. You can specify one or more of these modifiers:
detail—Detailed trace information
receive—Packets being received
send—Packets being transmitted
no-stamp—(Optional) Do not place timestamp information at the beginning of each line in the trace file.
Default: If you omit this option, timestamp information is placed at the beginning of each line of the tracing output.
no-world-readable—(Optional) Do not allow users to read the log file.
replace—(Optional) Replace an existing trace file if there is one.
Default: If you do not include this option, tracing output is appended to an existing 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 this 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 must also include the files statement to specify the maximum number of trace files.
Syntax: xk to specify KB, xm to specify MB, or xg to specify GB
Range: 10 KB through the maximum file size supported on your system
Default: 1 MB
world-readable—(Optional) Allow any user to read the log file.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
