The Juniper Networks EX Series
Ethernet Switches
The Juniper Networks EX3200, EX4200, and EX8200 Ethernet switches exhibit five key
characteristics that, working together, deliver a true enterprise switching solution: carrier-
class reliability, security risk management, network virtualization, application control, and
reduced total cost of ownership (TCO).
Carrier-class Reliability:
Nothing succeeds like success. That’s why the Juniper
Networks EX Series Ethernet Switches leverage much of the same field-proven
Juniper Networks technology—including high-performance application-specific
integrated circuits (ASICs), system architecture and Juniper Networks Junos
®
operating system—that power the world’s largest service provider networks.
The result is a robust, time-tested and highly reliable network infrastructure
solution for high-performance enterprises.
Security Risk Management:
The Juniper Networks EX Series Ethernet
Switches are fully compatible with the Juniper Networks Unified Access
Control (UAC), delivering an extra layer of security by first authenticating
users and performing virus checks, then enforcing precise, end-to-end security
policies that determine who can access what network resources, as well
as quality of service (QoS) policies to ensure delivery of business processes.
Integrated anomaly-based threat detection provides additional protection by
identifying and blocking distributed denial of service (DDoS) attacks.
Network Virtualization:
The EX Series switches feature Juniper Networks Virtual Chassis
technology, which enables up to 10 EX4200 switches to be interconnected and operate
as a single system. With Virtual Chassis technology, users get the reliability, availability
and high-port densities of traditional chassis-based systems in a cost-effective, compact
form factor—the best of both worlds. The EX Series switches also support generic routing
encapsulation (GRE) tunneling for sending mirrored traffic from remote locations to
monitoring devices in the network operations center for centralized troubleshooting and
analysis, or to build segregated overlay networks without the challenges associated with
Spanning Tree.
