Data SheetEX2300 Ethernet Switch
• Support for L2 protocols as well as L3 protocols like RIP and
static routing are included in the base license.
• An optional enhanced license is available for supporting
additional L3 protocols such as OSPF, Internet Group
Management Protocol (IGMP v1/v2/v3), Protocol Independent
Multicast (PIM), Bidirectional Forwarding Detection (BFD),
and Virtual Router Redundancy Protocol (VRRP).
• Support is available for IPv6 management, including
neighbor discovery, telnet, SSH, DNS, system log, and NTP.
• A single release train for Juniper Networks Junos operating
system is supported to ensure a consistent control plane
feature implementation.
• Modular Junos OS prevents a switch reboot if a single
protocol feature fails.
• The device integrates with Juniper Networks Unified Access
Control to provide per-user access control and policing.
• Built-in Web interface (Juniper Networks J-Web Software)
is provided.
• RJ-45 serial console port is available.
• USB mini console port is included.
• Out-of-band Ethernet management port is provided.
• Reduction of Hazardous Waste (RoHS) is certified.
Architecture and Key Components
The EX2300 occupies a single rack unit, delivering a compact
solution for crowded wiring closets and access locations where
space and power are at a premium. The EX2300 switch’s
10-inch/12-inch depth and low acoustics also make it ideal for
open oce deployments. For silent operation requirements, please
see the EX2300-C, a compact, fanless version of the EX2300.
Each EX2300 switch supports four fixed front-panel 1GbE/10GbE
uplink ports with pluggable optics (purchased separately) for
high-speed backbone or link aggregation connections between
wiring closets and upstream aggregation switches. The EX2300
also features a front-panel mode button that offers a simple
interface for bringing devices up and selecting LED modes.
A dedicated rear panel RJ-45 Ethernet port is available for out-
of-band management, while a rear panel USB port can be used
to easily upload the Junos OS and configuration files.
Junos Fusion Enterprise Technology
Juniper Networks Junos Fusion Enterprise technology provides
automated network configuration and simplifies scalability for
medium to large enterprise networks. Using Juniper Networks
EX9200 line of programmable switches as aggregation devices
and EX2300 switches as satellite nodes, Junos Fusion Enterprise
technology can be deployed across a building (or multiple
buildings) to connect large numbers of switches in a fabric that
can be managed as a single device.

switches as satellite devices
With Junos Fusion technology, enterprises can reduce network
complexity and operational costs by collapsing underlying
network elements into a single logical point of control from
Junos OS-based Juniper routing and switching platforms. It is
designed for customers who need to cost-effectively deploy
numerous switch ports throughout their enterprise campus
network and manage them all from a central device. In addition,
existing EX2300 switches can be easily added to a Junos Fusion
Enterprise deployment with a simple software upgrade, offering
full investment protection.
In Junos Fusion Enterprise deployments, satellite devices do not
require to be individually connected to aggregation devices. Up
to 10 satellite devices can be interconnected via standard 10GbE
interfaces to form a “cluster,” which in turn can be connected to
the aggregation device(s) over a pair of fiber uplinks. Satellite
devices or clusters can also be dual-homed or single-homed to
the aggregation devices.
In Junos Fusion Enterprise deployments, satellite devices forward all
trac to the aggregation device, enabling network administrators
to monitor and manage the entire enterprise campus building from
a single device. Features such as PoE/PoE+, LLDP-MED, and 802.1x
are also supported in Junos Fusion Enterprise architectures to help
meet enterprise campus requirements.
Virtual Chassis Technology
The EX2300 supports Juniper’s unique Virtual Chassis
technology, enabling up to four interconnected EX2300 switches
to be managed as a single logical device, delivering a scalable,
pay-as-you-grow solution for expanding network environments.
While EX2300 switches can be interconnected over any of the
front-panel uplink ports using standard 10GbE SFP+ transceivers
(sold separately), these ports can also be configured as
1GbE/10GbE uplinks to aggregation devices by disabling the
Virtual Chassis technology.
When deployed in a Virtual Chassis configuration, the EX2300
switches elect a primary and a backup switch based on a
set of preconfigured policies or criteria. The primary switch
automatically creates and updates the switching and optional
routing tables on all other Virtual Chassis switch members.
Switches can be added to or removed from the Virtual Chassis
configuration without service disruption.
