Using the Examples in This Manual

If you want to use the examples in this manual, you can use the load merge or the load merge relative command. These commands cause the software to merge the incoming configuration into the current candidate configuration. The example does not become active until you commit the candidate configuration.

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

If the example configuration does not start at the top level of the hierarchy, the example is a snippet. In this case, use the load merge relative command. These procedures are described in the following sections.

Merging a Full Example

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;

}

} }

xii

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

[edit] user@host# load merge /var/tmp/ex-script.conf load complete

Merging a Snippet

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. Move to the hierarchy level that is relevant for this snippet by issuing the following configuration mode command:

[edit] user@host# edit system scripts [edit system scripts]

xiii

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

[edit system scripts] user@host# load merge relative /var/tmp/ex-script-snippet.conf load complete

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

Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The Juniper Networks EX2300 Ethernet Switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services.

EX2300 switches provide connectivity for low-density environments.

Benefits of the EX2300 Switch

Economical—EX2300 switches offer an economical, entry-level, standalone solution for access-layer deployments in branch and remote offices, as well as enterprise campus networks. 1 Gbps and 2.5 Gbps access port options provide high speed options, especially when connecting to 802.11ac Wave 2 access points.

High flexibility and class leading features—EX2300 switches provide the highest levels of flexibility and features in its class to support data, voice, and video environments, delivering a reliable platform for unifying enterprise communications.

Support for Juniper Networks Junos Fusion Enterprise—EX2300 switches can act as a satellite device to support a Juniper Networks Junos Fusion Enterprise deployment, which can combine several wiring closets into one logical management platform. In smaller networks, you can connect up to four EX2300 switches in a Virtual Chassis configuration, allowing them to be managed as a single switch.

EX2300 Switches First View

EX2300 switches are available in models with 12 or 24, or 48 built-in network ports that support RJ-45 cable connectors. The compact, fanless EX2300-C switches have 12 RJ-45 network ports.

EX2300 switches provide:

Up to six 10-Gigabit Ethernet uplink ports that support small form-factor pluggable plus (SFP+) transceivers

•

and small form-factor pluggable (SFP) transceivers.

12 (in EX2300-C switches), 16, 24, 32, or 48 built-in Gigabit Ethernet RJ-45 network ports with

•

10/100/1000 BASE-T connectors.

Eight or 16 built-in Gigabit Ethernet RJ-45 network ports with 100/1000/2500 BASE-T connectors.

•

Virtual Chassis capability—You can connect up to four EX2300 switches (including EX2300-C switches)

•

to form one unit that you manage as a single chassis, called a Virtual Chassis.

Power over Ethernet (PoE) or Power over Ethernet Plus (PoE+) on all RJ-45 network ports (in PoE-capable

•

models).

Uplink Ports

EX2300-C switches have two 10-Gigabit Ethernet uplink ports. EX2300 switches except the EX2300-C switch model and the EX2300-48MP switch model have four 10-Gigabit Ethernet uplink ports. The EX2300-48MP switch model has six 10-Gigabit Ethernet uplink ports. These uplink ports support SFP and SFP+ transceivers. You can use these uplink ports as network ports or configure these ports as Virtual Chassis ports (VCPs) and use them to connect up to four switches by using SFP+ transceivers to form a Virtual Chassis.

NOTE: You cannot form a Virtual Chassis by using SFP transceivers.

For forming a Virtual Chassis, you must explicitly configure an uplink port on each of the switches to be connected as a VCP. See Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual Chassis Port.

For information about the supported optical and copper interfaces, see “Pluggable Transceivers Supported

on EX2300 Switches” on page 80.

Console Ports

EX2300 switches except the EX2300-24MP and EX2300-48MP switch models have two console ports—an RJ-45 console port and a Mini-USB Type-B console port. EX2300-24MP and EX2300-48MP switch models have an RJ-45 console port. The RJ-45 port accepts a cable that has an RJ-45 connector and the Mini-USB Type-B port accepts a Mini-B plug (5-pin) connector to connect the switch to a console management device.

Cable Guard

On an EX2300-C switch, you can install a cable guard to secure the cables connected to the switch. The cable guard has slots in the front of it through which you can pass all the cables to prevent them from being accidently unplugged or removed after they are connected. See “Mounting an EX2300 Switch on a

Desk or Other Level Surface” on page 106, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws” on page 108, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 126.

Security Slot

An EX2300-C switch has a security slot on the right panel of the chassis. You can use the security slot to lock and secure the chassis in the installation site with a standard cable lock. See “Mounting an EX2300

Switch on a Desk or Other Level Surface” on page 106, “Mounting an EX2300-C Switch Under a Desk or Other Level Surface by Using Screws” on page 108, and “Mounting an EX2300-C Switch on or Under a Surface Made of Ferrous Material” on page 126.

Power over Ethernet (PoE) Ports

EX2300 switches are available with or without PoE/PoE+ capability. Models that support PoE/PoE+ provide that support on all RJ-45 network ports. PoE ports provide electrical current to devices—such as IP phones, wireless access points, and security cameras—through network cables, thus eliminating the need for separate power cords for those devices. Uplink ports do not support PoE.

NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher Ethernet cables.

The remainder of this topic uses the term PoE to refer to both PoE and PoE+ unless there is a need to distinguish between the two.

Front Panel of an EX2300 Switch

The front panel of an EX2300-C switch consists of the following components:

RJ-45 network ports—depending on the switch model, either of:

•

12 10/100/1000 BASE-T Gigabit Ethernet ports with PoE/PoE+ capability in EX2300-C-12P
