traceoptions (DHCP)
Syntax
Hierarchy Level
Release Information
Statement introduced in Junos OS Release 11.4.
Description
Define global tracing operations for extended DHCP local server and extended DHCP relay agent processes.
Replaces deprecated traceoptions statements at the [edit forwarding-options dhcp-relay] and [edit system services dhcp-local-server] hierarchy levels.
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 to create before overwriting the oldest one. 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 flag—Tracing operation to perform. To specify more than one tracing operation, include multiple flag statements
- all—Trace all events.
- auth—Trace authentication events.
- database—Trace database events.
- fwd—Trace firewall process events.
- general—Trace miscellaneous events.
- ha—Trace high availability-related events.
- interface—Trace interface operations.
- io—Trace I/O operations.
- packet—Trace packet and option decoding operations.
- performance—Trace performance measurement operations.
- profile—Trace profile operations.
- rpd—Trace routing protocol process events.
- rtsock—Trace routing socket operations.
- session-db—Trace session database events.
- state—Trace changes in state.
- statistics—Trace baseline statistics.
- ui—Trace user interface operations.
level—Level of tracing to perform; also known as severity level. The option you configure enables tracing of events at that level and all higher (more restrictive) levels. You can specify any of the following levels:
- all—Match messages of all levels.
- error—Match error messages.
- info—Match informational messages.
- notice—Match notice messages about conditions requiring special handling.
- verbose—Match verbose messages. This is the lowest (least restrictive) severity level; when you configure verbose, messages at all higher levels are traced. Therefore, the result is the same as when you configure all.
- warning—Match warning messages.
match regular-expression—(Optional) Refine the output to include lines that contain the regular expression.
no-remote-trace—Disable remote tracing.
no-world-readable—(Optional) Disable unrestricted file access, allowing only the user root and users who have the Junos OS maintenance permission to access the trace files.
size maximum-file-size—(Optional) Maximum size of each trace file. By default, the number entered is treated as bytes. Alternatively, you can include a suffix to the number to indicate kilobytes (KB), megabytes (MB), or gigabytes (GB). If you specify a maximum file size, you also must specify a maximum number of trace files with the files option.
Syntax: sizek to specify KB, sizem to specify MB, or sizeg to specify GB
Range: 10240 through 1073741824
Default: 128 KB
world-readable—(Optional) Enable unrestricted file access.
Required Privilege Level
trace—To view this statement in the configuration.
trace-control—To add this statement to the configuration.
