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.
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.

• Non-Stop Bridging (NSB) and Non-stop Routing (NSR): NSB and

and tables are synchronized between master and backup REs to
prevent protocol flaps or convergence issues following a Routing
Engine failover.

• Non-Stop Software Upgrade (NSSU): with NSSU, all members
of an EX3300 Virtual Chassis configuration can be upgraded with
a single command. Mission-critical traffic 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.

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 software,
providing a complete, consolidated view of network operations.
