The EX3200 offers an integrated Routing Engine (RE) that runs

the same modular Juniper Networks Junos OS as Juniper ’s router

products to ensure the consistent implementation and operation

of each control plane feature across an entire Juniper Networks

infrastructure.

Each EX3200 switch includes an integrated application-specific

integrated circuit (ASIC)-based Packet Forwarding Engine, the

EX-PFE, to consistently deliver wire-rate forwarding even with all

control-plane features enabled. Based on existing field-proven

Juniper Networks technology, the EX-PFE and RE bring the same

level of carrier-class performance and reliability to the EX3200

line of Ethernet switches that Juniper Networks routers bring to

the world’s largest service provider networks.

Architecture and Key Components

The EX3200 occupies a single rack unit and deliver a compact

solution for crowded wiring closets and access locations where

space and power are at a premium.

Each EX3200 switch supports optional front-panel uplink modules

oering either four GbE ports or two 10 GbE ports with pluggable

optics for high-speed backbone or link-aggregation connections

between wiring closets and upstream aggregation switches. Uplink

modules can be installed without powering down the switch,

enabling users to add high-speed connectivity at any time or to

migrate from GbE to 10 GbE uplinks, delivering the ultimate in

flexible, high-performance interconnectivity.

The EX3200 also features a front-panel LCD display that oers a

flexible interface for performing device bring-up and configuration

rollbacks, for reporting switch alarm and LED status, or for restoring

the switch to its default settings.

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 Junos OS and configuration files.

Features and Benefits

High Availability Features

• Field-replaceable power supplies: The EX3200 supports field-

replaceable AC and DC power supplies, reducing MTTR. When

deployed with an optional redundant power supply (RPS) unit*,

the internal replaceable power supply on the EX3200 becomes

hot-swappable.

• Hot-swappable fan tray: The EX3200 includes a hot-

swappable, field-replaceable fan tray, reducing MTTR.

• Carrier-class hardware: The EX3200 leverages a purpose-built

packet forwarding engine ASIC—the EX-PFE—which integrates

much of the same intellectual property used in Juniper

Networks carrier routers. As a result, the EX3200 delivers the

same predictable, scalable functionality found in the world’s

largest networks.

• Redundant Trunk Group (RTG): To avoid the complexities of

the Spanning Tree Protocol (STP) without sacrificing network

resiliency, the EX3200 employs a redundant trunk group to

provide the necessary port redundancy and simplify switch

configuration.

Carrier-Class Operating System

The EX3200 runs the same Junos OS used by Juniper Networks
routers to power the world’s largest and most complex networks.

By utilizing a common operating system, Juniper delivers a
consistent implementation and operation of control-plane features
across all products—functions ranging from chassis management
to spanning tree to OSPF. To maintain that consistency, Junos OS
adheres to a highly disciplined development process that utilizes
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 products powered by the Junos OS—routers
and switches—to be updated simultaneously with the same
software release. All features, new and old, are fully regression­tested, making each new release a true superset of the previous
version. Customers can deploy a new Junos OS release with
complete confidence that all existing capabilities will operate in
the same way and be compatible on all Juniper Networks switches
and routers in the network.

Security

The EX3200 fully integrates with the Juniper Networks Unified
Access Control (UAC), which consolidates all aspects of a user’s
identity, device and location. This enables administrators to enforce
access control and security down to the individual port or user levels.

Working as an enforcement point within UAC, the EX3200
provides both standards-based 802.1X port-level access
control for multiple devices per port, as well as 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 determine whether access should be granted and
for how long. If access is granted, the switch assigns the user’s
device to a specific VLAN based on authorization policy. The
switch can also apply security and/or QoS policies, or it can mirror
user traffic to a central location for logging, monitoring or threat
detection by intrusion prevention systems.

The EX3200 also provides a full complement of integrated port
security and threat detection features, including DHCP (Dynamic
Host Configuration Protocol) snooping, DAI (Dynamic ARP
Inspection) and MAC limiting to defend against internal and external

spoofing, man-in-the-middle and denial-of-service (DoS) attacks.

Converged Environments

The EX3200 provides the highest levels of availability in their
class for the most demanding converged data, voice and video
environments, delivering a reliable platform for unifying enterprise
communications.

By providing a full 15.4 watts of Class 3 PoE to power voice over
IP (VoIP) telephones, closed-circuit security cameras, wireless
access points and other IP-enabled devices, the EX3200 delivers
a future-proofed solution for converging disparate networks onto
a single IP infrastructure. The base system, which offers eight PoE
ports, lowers the cost and complexity of designing the access layer
by supporting a small number of WLAN access points or IP phones
rather than requiring the purchase of PoE on all 24 or 48 ports.

To ease deployment, the EX3200 supports the industry-standard
Link Layer Discovery Protocol (LLDP) and LLDP-Media

Endpoint Discovery (LLDP-MED) protocol, enabling the switches to
automatically discover Ethernet-enabled devices, determine their
power requirements, and assign virtual LAN (VLAN) membership.

In addition, the EX3200 supports rich quality of service (QoS)
functionality for prioritizing data, voice and video traffic. The
switches support eight class-of-service (CoS) queues on every
port, enabling them to maintain multi-level, end-to-end traffic
prioritizations. The EX3200 also supports a wide range of policy
options, including strict priority, low-latency, weighted random
early drop (WRED) and shaped deficit weighted round-robin
(SDWRR) queuing.

Simplified Management and Operations

The EX3200 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 interface or management system.

Four system management options are available for the
EX3200 line of Ethernet switches. The standard Junos OS CLI
management interface offers the same granular capabilities and
scripting parameters found in any router powered by Junos OS.
The EX3200 also includes the integrated J-Web management tool,
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.

When managing a group of EX3200 line of Ethernet switches, the
Juniper Networks Network and Security Manager (NSM) provides
system-level management across all Juniper switches in the
network from a single console.

Finally, the EX3200 configuration, fault, and performance data
can be exported to leading third-party management systems such
as HP OpenView, IBM Tivoli and Computer Associates Unicenter
software, to provide a complete, consolidated view of network
operations.

Limited Lifetime Warranty

The EX3200 includes a limited lifetime hardware warranty that
provides return-to-factory switch replacement for as long as the
original purchaser owns the product. Power supplies and fan trays
are covered for a period of five years. For complete details please
