Virtual Chassis Technology
The EX3300 supports Juniper Networks Virtual Chassis
technology, allowing up to 10 switches to be interconnected
over uplink ports and be managed as a single logical device,
delivering a scalable, pay-as-you-grow solution for expanding
network environments.
When deployed in a Virtual Chassis configuration, the EX3300
switches elect a master and backup switch based on a
set of criteria or preconfigured policies. The master switch
automatically creates and updates the switching and optional
routing tables on all switches in the Virtual Chassis configuration.
Virtual Chassis technology allows switches to be added or

standard 10GbE SFP+ or GbE SFP transceivers (sold separately).
These two ports can also be configured as GbE or 10GbE uplinks
to aggregation devices by disabling Virtual Chassis technology.
Converged LAN Environments
The EX3300 switches provide a flexible solution for demanding
converged data, voice, and video environments. The EX3300-24P
and EX3300-48P support the IEEE 802.3at Power over Ethernet
(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. The PoE+ standard provides nearly double the
15.4 watts per port available with the IEEE 802.3af PoE standard.

single telnet session, single command-line interface (CLI),
automatic version checking, and automatic configuration. The
EX3300 switches are also capable of local switching, so that
packets coming into a port destined for another port on the same
switch do not have to traverse the Virtual Chassis, increasing the
10GbE Virtual Chassis
forwarding capacity of the switch.
The EX3300 implements the same slot/module/port numbering

The EX3300-48P includes a total PoE power budget of 740
watts, enabling the switch to provide the full 15.4 watts of
802.3af Class 3 PoE to all 48 ports, or the full 30 watts of PoE+
to 24 ports. The switch can support any combination of PoE and
PoE+ ports until the maximum PoE power budget of 740 watts is
exhausted.
The EX3300-24P includes a total power budget of 405 watts,
enabling the switch to provide the full 15.4 watts of PoE power to
all 24 ports, or the full 30 watts of PoE+ to 13 attached devices.
The switch can support any combination of PoE and PoE+ ports
until the maximum PoE power budget of 405 watts is exhausted.

There are two PoE power mode settings on the EX3300 switches:
• Static mode, which allows customers to specify the
maximum PoE power setting on an individual port
• Class mode, which allows end devices to specify PoE class
and negotiate whether the switch can provide PoE power to
the device
The EX3300 also supports the industry-standard Link Layer
Discovery Protocol (LLDP) and LLDP-Media Endpoint Discovery
(LLDP-MED), which enable the switches to automatically
discover Ethernet-enabled devices, determine their power
requirements, and assign virtual LAN (VLAN) parameters. LLDP-
MED-based granular PoE management allows the EX3300 to
negotiate PoE usage down to a fraction of a watt on powered
devices, enabling more efficient PoE utilization across the switch.
The EX3300 supports the Institute of Electrical and Electronics
Engineers (IEEE) 802.3az standard for Energy Efficient Ethernet
(EEE) functionality, reducing power consumption of copper
physical layers (PHY) during periods of low link utilization.
In addition, the EX3300 supports rich quality-of-service (QoS)
functionality for prioritizing data, voice, and video trac. The
switches support eight QoS queues on every port, enabling them to
maintain multilevel, end-to-end trac prioritization. The EX3300
also supports a wide range of scheduling options, such as priority
and shaped deficit weighted round-robin (SDWRR) scheduling.
An external redundant power system (RPS) delivering additional
power resiliency is also available.
Data Center Gigabit Ethernet Server Access
The EX3300 switches are optimized for GbE server access
deployments in the data center, with front-to-back and back-
to-front cooling. The four SFP+ uplink ports on the EX3300 can
operate at 10 Gbps simultaneously, offering up to 20GbE of uplink
connectivity to each of the dual aggregation switches.

Security
The EX3300 switches fully interoperate with Juniper Networks
Unified Access Control, which consolidates all aspects of a user’s
identity, device, and location, enabling administrators to enforce
access control and security down to the individual port or user
levels. Working as an enforcement point within the UAC, the
EX3300 provides both standards-based 802.1X port-level access
control and Layer 2-4 policy enforcement based on user identity,
location, and/or device. A user’s identity, device type, machine
posture check, and location can be used to not only grant or deny
access but also to determine the duration of access. If access is
granted, the switch assigns the user to a specific VLAN based on
authorization levels. The switch can also apply QoS policies or
mirror user traffic to a central location for logging, monitoring, or
threat detection by intrusion prevention systems (IPS).
The EX3300 also provides a full complement of port security
features, including Dynamic Host Configuration Protocol (DHCP)
snooping, dynamic ARP inspection (DAI), and media access control
(MAC) limiting to defend against internal and external spoofing,
man-in-the-middle, and denial-of-service (DoS) attacks.

Data SheetEX3300 Ethernet Switch
Junos Operating System
The EX3300 switches run the same Junos OS used by other EX
Series Ethernet Switches, as well as Juniper routers and Juniper
Networks SRX Series Services Gateways. By utilizing a common
operating system, Juniper delivers a consistent implementation
and operation of control plane features across all products.
To maintain that consistency, Junos OS adheres to a highly
disciplined development process that uses a single source code,
follows a single quarterly release train, and employs a highly
available modular architecture that prevents isolated failures
from bringing an entire system down.
These attributes are fundamental to the core value of the
software, enabling all Junos OS-powered products to be updated
simultaneously with the same software release. All features are
fully regression tested, making each new release a true superset
of the previous version; customers can deploy the software
with complete confidence that all existing capabilities will be
maintained and operate in the same way.
High Availability
The EX3300 line of Ethernet switches is designed to support
many of the same failover capabilities and high availability (HA)
functionality as the Juniper Networks EX4200 line of Ethernet
switches with Virtual Chassis technology.
Each EX3300 switch is capable of functioning as a Routing
Engine when deployed in a Virtual Chassis configuration. When
two or more EX3300 switches are interconnected in a Virtual
Chassis configuration, all member switches share a single control
plane. Junos OS automatically initiates an election process to
assign a master (active) and backup (hot-standby) Routing
Engine. An integrated Layer 2 and Layer 3 graceful Routing Engine
switchover (GRES) feature maintains uninterrupted access to
applications, services, and IP communications in the unlikely
event of a master Routing Engine failure.
When more than two switches are interconnected in a Virtual
Chassis configuration, the remaining switch elements act as line
cards and are available to assume the backup Routing Engine
position should the designated master fail. Master, backup
and line card priority status can be assigned by the network
operations team to dictate the order of ascension. This N+1
Routing Engine redundancy, coupled with GRES, the nonstop
routing (NSR) and, in the future, the nonstop bridging (NSB)
capabilities of Junos OS, ensures a smooth transfer of control
plane functions following unexpected failures.
The EX3300 also supports the following HA features:
• Redundant trunk group: To avoid the complexities of
Spanning Tree Protocol (STP) without sacrificing network
resiliency, the EX3300 employs redundant trunk groups to
provide the necessary port redundancy and simplify switch
configuration.
• Cross-member link aggregation: Cross-member link
aggregation allows redundant link aggregation connections
between devices in a single Virtual Chassis configuration,
providing an additional level of reliability and availability.
• Non-Stop Bridging (NSB) and Non-stop Routing (NSR):
NSB and NSR on the EX3300 switch ensure control plane
protocols, states and tables are synchronized between
master and backup REs to prevent protocol flaps or
convergence issues following a Routing Engine failover.
• Non-Stop Soware Upgrade (NSSU): With NSSU, all
members of an EX3300 Virtual Chassis configuration can
be upgraded with a single command. Mission-critical trac
can be configured as a link aggregate across multiple Virtual
Chassis switch members, ensuring minimal disruption during
the upgrade process.
Simplified Management and Operations
When deployed in a Virtual Chassis configuration, the EX3300
dramatically simplifies network management. Up to 10
interconnected EX3300 switches can be managed as a single
device utilizing a single Junos OS image file and a single
configuration file, reducing the overall number of units to monitor
and manage. When the Junos OS is upgraded on the master
switch in an EX3300 Virtual Chassis configuration, the software
is automatically upgraded on all other member switches at the
same time.
The EX3300 includes port profiles that allow network
administrators to automatically configure ports with security,
QoS, and other parameters based on the type of device
connected to the port. Six preconfigured profiles are available,
including default, desktop, desktop plus IP phone, WLAN access
point, routed uplink, and Layer 2 uplink. Users can select from
the existing profiles or create their own and apply them through
the command-line interface (CLI), J-Web Software interface, or
Junos Space network management system.
In addition, a feature called System Snapshot makes a copy
of all software files used to run the switch, including the Junos
operating system, the active configuration and the rescue
configuration, that can be used to reboot the switch at the next
power-up or as a backup boot option. The Junos OS software
can also be preinstalled on a flash drive and used to boot the
EX3300 at any time.
Another feature, called automatic software download, enables
network administrators to easily upgrade the EX3300 using
the DHCP message exchange process to download and install
software packages. Users simply configure the automatic
software download feature on EX3300 switches acting as DHCP
clients and establish a path to the server where the software
package file is installed. The server then communicates the path
to the software package file through DHCP server messages.
An EZ touchless provisioning feature allows a DHCP server to
push configuration details and software images to multiple
switches at bootup.

Data SheetEX3300 Ethernet Switch
Three system management options are available for the EX3300
line. The standard Junos OS CLI management interface offers
the same granular capabilities and scripting parameters found in
any router powered by the Junos operating system. The EX3300
also includes the integrated J-Web interface, an embedded web-
based device manager that allows users to configure, monitor,
troubleshoot, and perform system maintenance on individual
switches via a browser-based graphical interface.
Finally, EX3300 fault, configuration and performance data can be
exported to leading third-party management systems such as HP
OpenView, IBM Tivoli, and Computer Associates Unicenter soware,
providing a complete, consolidated view of network operations.
