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.

Power over Ethernet Ports | 21

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

Juniper Networks EX3400 Ethernet Switches provide connectivity for low-density environments.

Benefits of the EX3400 Switch

High flexibility—EX3400 switches provide a flexible solution that supports converged data, voice, and video environments.

Support for MACsec—EX3400 switches support IEEE 802.1AE MACsec, providing support for link-layer data confidentiality, data integrity, and data origin authentication. The MACsec feature enables EX3400 to support 88 Gbps of near line-rate hardware-based traffic encryption on all Gigabit Ethernet and 10 Gigabit Ethernet ports.

Nondisruptive software upgrades—EX3400 switches feature a resilient operating system that supports high availability (HA) features such as graceful Routing Engine switchover (GRES), nonstop active routing (NSR), and nonstop software upgrade (NSSU), providing software upgrades and changes without disrupting network traffic.

EX3400 Switches First View

EX3400 switches provide:

Either 24 or 48 RJ-45 ports (labeled 0 through 23 or 0 through 47) that support 10/100/1000BASE-T

•

Gigabit Ethernet connectors.

Four uplink ports (labeled 0 through 3 on the front panel) that support small form-factor pluggable (SFP)

•

transceivers and small form-factor pluggable plus (SFP+) transceivers, and two 40-Gigabit Ethernet ports (labeled 0 through 1 on the rear panel) that support quad small form-factor pluggable plus (QSFP+) transceivers.

Virtual Chassis capability—You can connect up to 10 EX3400 switches together 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 ports (in PoE-capable models).

•

Uplink Ports

EX3400 switches have autosensing uplink ports that you can use to:

Connect an access switch to a distribution switch

•

Interconnect member switches of a Virtual Chassis

•

The QSFP+ uplink ports are configured as Virtual Chassis ports (VCPs) by default. You can use these ports to interconnect Virtual Chassis members. To use the QSFP+ uplink ports as network ports, you must configure them as network ports. The uplink ports on the front panel are configured as network ports by default. To use the uplink ports on the front panel as VCPs, you must configure them as VCPs. See Setting an Uplink Port on an EX Series or QFX Series Switch as a Virtual Chassis Port.

The uplink ports on the front panel support four 1-gigabit SFP transceivers, four 10-gigabit SFP+ transceivers, or a combination of four SFP+ and SFP transceivers. The QSFP+ uplink ports support 40-gigabit QSFP+ transceivers. For a list of supported transceivers, see “Pluggable Transceivers Supported on EX3400

Switches” on page 66.

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

Virtual Chassis

You can interconnect a maximum of 10 EX3400 switches to form a Virtual Chassis. You can operate these interconnected switches as a single, logical device with a single IP address.

You can use the following ports to interconnect an EX3400 switch in a Virtual Chassis:

QSFP+ ports configured as VCPs by using QSFP+ transceivers

•

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

Uplink ports on the front panel configured as VCPs by using SFP+ transceivers

By default, the QSFP+ ports are configured as VCPs.

Console Ports

EX3400 switches have two console ports—an RJ-45 console port and a Mini-USB Type-B console port. The RJ-45 console port is on the rear panel of the switch and the mini-USB console port is on the front panel. Both console ports are labeled CON. The RJ-45 console port accepts a cable that has an RJ-45 connector and the Mini-USB Type-B console port accepts a Mini-B plug (5-pin) connector to connect to the console management device.

Power over Ethernet Ports

EX3400 switches are available with or without Power over Ethernet (PoE) or Power over Ethernet Plus (PoE+) capability. Models that support PoE or PoE+ provide that support on all RJ-45 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.

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

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

EX3400 Switch Models

EX3400 switch models are available:

With 24 or 48 RJ-45 ports

•

With or without PoE+ capability

•

With front-to-back or back-to-front airflow
