To obtain the most current version of all Juniper Networks® technical documentation, see the product documentation page on the Juniper Networks website at https://www.juniper.net/documentation/.

Iftheinformationinthelatestreleasenotesdiffersfromtheinformationinthedocumentation,followthe product Release Notes.

UsingtheExamplesinThisManual

If you want to use the examples in this manual, you can use the loadmerge or the loadmergerelative command. These commands cause the software to merge the incoming configuration into the current candidateconfiguration.Theexampledoesnotbecomeactiveuntilyoucommitthecandidateconfiguration.

If the example configuration contains the top level of the hierarchy (or multiple hierarchies), the example is a fullexample. In this case, use the loadmerge command.

If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In thiscase,usetheloadmergerelative command.Theseproceduresaredescribedinthefollowingsections.

MergingaFullExample

To merge a full example, follow these steps:

1.From the HTML or PDF version of the manual, copy a configuration example into a text file, save the file with a name, and copy the file to a directory on your routing platform.

For example, copy the following configuration to a file and name the file ex-script.conf. Copy the ex-script.conf file to the /var/tmp directory on your routing platform.

system { scripts {

commit {

file ex-script.xsl;

}

interfaces { fxp0 {

disable; unit 0 {

family inet {

address 10.0.0.1/24;

}

2.Merge the contents of the file into your routing platform configuration by issuing the loadmerge configuration mode command:

[edit]

user@host# loadmerge/var/tmp/ex-script.conf load complete

MergingaSnippet

To merge a snippet, follow these steps:

1.From the HTML or PDF version of the manual, copy a configuration snippet into a text file, save the file with a name, and copy the file to a directory on your routing platform.

For example, copy the following snippet to a file and name the file ex-script-snippet.conf. Copy the ex-script-snippet.conf file to the /var/tmp directory on your routing platform.

commit {

file ex-script-snippet.xsl; }

2.Movetothehierarchylevelthatisrelevantforthissnippetbyissuingthefollowingconfigurationmode command:

[edit]

user@host# editsystemscripts

[edit system scripts]

3.Merge the contents of the file into your routing platform configuration by issuing the loadmerge relative configuration mode command:

[edit system scripts]

user@host# loadmergerelative/var/tmp/ex-script-snippet.conf load complete

For more information about the load command, see CLI Explorer.

SRX320ServicesGatewayDescription

The SRX320 Services Gateway consolidates security, routing, switching, and WAN interfaces for small distributed enterprises. With advanced threat mitigation capabilities, the services gateway provides cost-effective and secure connectivity across distributed enterprises.

With a desktop form-factor chassis, the SRX320 Services Gateway has six 1 G Ethernet ports, two 1 G SFP ports, 4 GB of DRAM memory, 8 GB of flash memory, and two Mini-Physical Interface Module (Mini-PIM) slots.

The SRX320 Services Gateway is available with or without Power over Ethernet (PoE) capability. In the PoE model. the six Ethernet ports are PoE capable.

The SRX320 Services Gateway runs the Junos operating system (Junos OS) and supports the following features:

•Firewall support with key features such as IPsec and VPN

•Intrusion Detection and Prevention (IDP)

•High availability

•QoS

•MPLS

You can manage the SRX320 Services Gateway by using the same interfaces that you use for managing other devices that run Junos OS—the CLI, the J-Web graphical interface, and Junos Space.

SRX320ServicesGatewayFieldReplaceableUnitsOverview

Field-replaceableunits(FRUs)arecomponentsthatyoucanreplaceatyoursite.TheMini-PhysicalInterface Module (MPIM) is the only FRU on the SRX320 Services Gateway.

The Mini-PIMs are not hot-swappable. You must power off the services gateway before removing or installing Mini-PIMs.

SRX320ServicesGatewayInterfaceModulesOverview

Mini-PhysicalInterfaceModules(Mini-PIMs)arefield-replaceablenetworkinterfacecards(NICs)supported on the SRX300 line of services gateways. You can easily insert or remove Mini-PIMs from the front slots of the services gateway chassis. The Mini-PIMs provide physical connections to a LAN or a WAN. The Mini-PIMs receive incoming packets from the network and transmit outgoing packets to the network. During this process, they perform framing and line-speed signaling for the medium type.

CAUTION: The Mini-PIMs are not hot-swappable. You must power off the services gateway before removing or installing Mini-PIMs.

The following Mini-PIMs are supported on the SRX320 Services Gateway:

•1-Port Serial Mini-Physical Interface Module (SRX-MP-1SERIAL-R)

•1-Port T1/E1 Mini-Physical Interface Module (SRX-MP-1T1E1-R)

•1-Port VDSL2 (Annex A) Mini-Physical Interface Module (SRX-MP-1VDSL2-R)

•LTE Mini-Physical Interface Module (SRX-MP-LTE-AE and SRX-MP-LTE-AA)

•Wi-FiMini-PhysicalInterfaceModule(SRX-MP-WLAN-US,SRX-MP-WLAN-IL,andSRX-MP-WLAN-WW)

For more information on the Mini-PIMs, see the SRX300 Series and SRX550 High Memory Gateway Interface Modules Reference.
