Data SheetEX2300 Ethernet Switch
EX2300 Virtual Chassis configurations operate as highly resilient
unified systems, providing simplified management using a single
IP address, single telnet session, single command-line interface
(CLI), automatic version checking, and automatic configuration.
The EX2300 switches are also capable of local switching, so
packets coming into a port destined for another port on the same
switch do not have to traverse the Virtual Chassis, increasing
forwarding capacities.
EX2300 Virtual Chassis configurations implement the
same slot/module/port numbering schema as other Juniper
Networks chassis-based products, providing true chassis-like
operations. By using a consistent operating system and a single
configuration file, all switches in a Virtual Chassis configuration
are treated as a single device, simplifying overall system
maintenance and management.
Simplified Management and Operations
Junos Fusion Enterprise technology dramatically simplifies EX2300
management by enabling a large number of the switches to
be managed from a single interface when deployed as satellite
devices. With features such as plug-and-play deployment and
rolling soware upgrades, Junos Fusion Enterprise eliminates the
need to individually manage every access switch in the enterprise
network, leading to lower operational costs and overall lower TCO.
Virtual Chassis technology simplifies network management
for smaller deployments. Up to four interconnected EX2300
switches can be managed as a single device utilizing a single
Junos OS image and a single configuration file, reducing the
overall number of units to monitor and manage. When the Junos
OS is upgraded on the primary switch in an EX2300 Virtual
Chassis configuration, the software is automatically upgraded on
all other member switches at the same time.
The EX2300 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
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. These files 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 EX2300 at any time.
Another feature, called automatic software download, enables
network administrators to easily upgrade the EX2300 using
the DHCP message exchange process to download and install
software packages. Users simply configure the automatic
software download feature on EX2300 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.
A zero touch provisioning (ZTP) feature allows a DHCP server
to push configuration details and software images to multiple
switches at boot-up time.
Two system management options are available for the EX2300
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 EX2300
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.

operate as a single, logical device.
