services-options (Next Gen Services Interfaces)

Syntax

Hierarchy Level

Description

Define the service options to be applied on the virtual multi-service (VMS) interface.

This statement is supported only on the MX-SPC3 Services Card.

The remaining statements are explained separately. See CLI Explorer.

Options

file

Configure the trace file options.

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`. By default, the name of the file is the name of the process being traced.
files `number`	Maximum number of trace files. When a trace file named `trace-file` reaches its maximum size, it is renamed to `trace-file.0`, then `trace-file.1`, and so on, until the maximum number of trace files is reached. The oldest archived file is overwritten. If you specify a maximum number of files, you also must specify a maximum file size with the `size` option and a filename. Range: 2 through 1000 files Default: 10 files
match `regular-expression`	Refine the output to include lines that contain the regular expression.
size `maximum-file-size`	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 the `trace-file` again reaches its maximum 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 also must specify a maximum number of trace files with the `files` option and a filename. Syntax: `x K` to specify KB, `x m` to specify MB, or `x g` to specify GB Range: 0 KB through 1 GB Default: 128 KB
world-readable \| no-world-readable	By default, log files can be accessed only by the user who configures the tracing operation. The `world-readable` option enables any user to read the file. To explicitly set the default behavior, use the `no-world-readable` option.

flag

Trace operation to perform. To specify more than one trace operation, include multiple flag statements.

all	Trace with all flags enabled
basic-datapath	Trace basic packet flow activity
fragmentation	Trace IP fragmentation and reassembly events
high-availability	Trace flow high-availability information
host-traffic	Trace flow host traffic information
multicast	Trace multicast flow information
route	Trace route lookup information
session	Trace session creation and deletion events
session-scan	Trace session scan information
tcp-basic	Trace TCP packet flow information
tunnel	Trace tunnel information

no-remote-trace

Set remote tracing as disabled.

packet-filter filter-name

Packet filter to enable during the tracing operation. Configure the filtering options.

destination-port `port-identifier`	Match TCP/UDP destination port
destination-prefix `address`	Destination IP address prefix
interface `interface-name`	Logical interface
protocol `protocol-identifier`	Match IP protocol type
source-port `port-identifier`	Match TCP/UDP source port
source-prefix `address`	Source IP address prefix

rate-limit messages-per-second

Limit the incoming rate of trace messages.

trace-level

Set the level for trace logging. This option is available only when the flag is set.

brief	Trace key flow information, such as message types sent between SPU and central point, policy match, and packet drop reasons.
detail	Trace extensive flow information, such as detailed information about sessions and fragments. Detail is the default level.
error	Trace error information, such as system failure, unknown message type, and packet drop.

fragment-limit

Specify the maximum number of fragments to be supported for the PIC. This overrides the value specified, if any, in the set security flow fragment-limit statement.

reassembly-timeout

Specify the reassembly timeout value for all fragmentation packets for the PIC. This overrides the value specified, if any, in the set security flow reassembly-timeout statement

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 19.3R2.

Support introduced in Junos OS Release 20.3R1 for Next Gen Services on MX240, MX480 and MX960 routers for the flow configuration statement.
