deployment, and administration. The current list can be viewed at https://www.juniper.net/books.
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;
}
}
}
}
xi
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]
xii
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 switches run the Juniper Networks Junos
operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services.
The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series,
MX Series, and T Series routers and SRX Series services gateways.
Juniper Networks EX3300 Ethernet Switches provide connectivity for low-density environments.
Benefits of the EX3300 Switch
Support for Virtual Chassis—EX3300 switches support Virtual Chassis technology. You can interconnect
a maximum of 10 EX3300 switches to form a Virtual Chassis.
High flexibility—EX3300 switches provide a flexible solution that supports converged data, voice, and
video environments.
Support for Power over Ethernet (PoE)—EX3300-24P and EX3300-48P models support the IEEE 802.3at
PoE standard, also known as PoE+, delivering up to 30 watts of power per port to support networked
devices such as telephones, video cameras, IEEE 802.11n wireless LAN (WLAN) access points, and video
phones.
EX3300 Switches First View
EX3300 switches provide:
Either 24 or 48 built-in network ports with 10/100/1000BASE-T Gigabit Ethernet connectors (ports
•
labeled 0 through 23 or 0 through 47)
Four uplink ports (ports labeled 0 through 3)
•
Virtual Chassis capability—You can connect up to ten EX3300 switches together to form one unit that
•
you manage as a single chassis, called a Virtual Chassis.
Power over Ethernet Plus (PoE+) on all network ports (in PoE+-capable models only)
•
19
Uplink Ports
Each EX3300 switch has four autosensing uplink ports. You can use the uplink ports on the switch to:
Connect an access switch to a distribution switch
•
Interconnect member switches of a Virtual Chassis
•
The uplink ports labeled 0 and 1 (interfaces ge-0/1/0 and ge-0/1/1 or xe-0/1/0 and xe-0/1/1) are
configured by default as network ports. To use uplink ports 0 and 1 to interconnect Virtual Chassis members,
you must configure them as Virtual Chassis ports (VCPs).
The uplink ports labeled 2 and 3 (interfaces ge-0/1/2 and ge-0/1/3 or xe-0/1/2 and xe-0/1/3) are
configured by default as VCPs. You can use these uplink ports to interconnect Virtual Chassis members.
To use uplink ports 2 and 3 as network ports, you must configure them as network ports.
The uplink ports support SFP and SFP+ transceivers. For a list of supported transceivers, see “Pluggable
Transceivers Supported on EX3300 Switches” on page 61.
Power over Ethernet Plus Ports
EX3300 switches are available in models with or without PoE+ capability. Models that support PoE+
provide that support on all 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.
NOTE: IEEE 802.3af and IEEE 802.3at powered devices require category 5 or higher Ethernet
cables.
EX3300 Switch Models
The EX3300 switch models are available:
With 24 or 48 network ports
•
With or without PoE+ capability
•
With front-to-back or back-to-front airflow
•
With AC or DC power supplies
•

NOTE: In rare cases, EX3300 switches running a Junos OS release prior to Release 11.3R4 or
Release 11.4R2 might experience some traffic loss or a link failure as a result of
non-user-configurable settings that are not optimized. To resolve this issue, upgrade to one of
the following Junos OS releases:
Junos OS Release 11.3—R4 and later
•
Junos OS Release 11.4—R2 and later
•
Junos OS Release 12.1—R1 and later
