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 offering 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 that offers 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-of­band 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 field­replaceable AC and DC power supplies, reducing MTTR.

• 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.

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.

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.
Furthermore, any PoE port can provide up to 18.6 watts to power
wireless access points and other PoE powered devices requiring
more than Class 3, 15.4 watts of PoE.

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.

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.
