Hierarchy Level
[edit system processes dhcp-service]
Description
Configure extended DHCP tracing operations that can be enabled on a specific interface or group of interfaces.
Replaces deprecated interface-traceoptions statements
at the [edit forwarding-options dhcp-relay] and [edit
system services dhcp-local-server] hierarchy levels.
To enable the tracing operation on the specific interfaces,
you use the interface interface-name trace statement.
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 eventspacket—Trace packet and option decoding operationsstate—Trace changes in state
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 configureverbose, messages at all higher levels are traced. Therefore, the result is the same as when you configureall.warning—Match warning messages.
Default:
error
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.
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:

Range: 10240 through 1073741824
world-readable—(Optional) Enable unrestricted
file access.
Required Privilege Level
