Product Overview
The Juniper Networks EX2200 line of Ethernet switches offers a compact, high-performance solution for supporting today’s converged network access deployments.
Each EX2200 switch includes an application-specific integrated circuit (ASIC)-based Packet Forwarding Engine (PFE) with an integrated CPU to consistently deliver wire-rate forwarding, even with all control plane features enabled. Based on existing, field proven Juniper Networks technology, the PFE brings the same level of carrier-class performance and reliability to the EX2200 switches that Juniper Networks routers bring to the world’s largest service provider networks.
Architecture and Key Components
The EX2200 occupies a single rack unit, delivering a compact solution for crowded wiring closets and access locations where space and power are at a premium. The EX2200 switch’s 10inch depth and low acoustics also make it ideal for open office deployments.
Each EX2200 switch supports four fixed front panel GbE uplink ports with pluggable optics (purchased separately) for highspeed backbone or link aggregation connections between wiring closets and upstream aggregation switches. The EX2200 also features a front panel mode button that offers a simple interface for bringing devices up and selecting LED modes.
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 the Junos operating system and configuration files.

Virtual Chassis Technology
The EX2200 supports Juniper’s unique Virtual Chassis technology, enabling up to four interconnected EX2200 switches to be managed as a single logical device, delivering a scalable, pay-as-you-grow solution for expanding network environments.
While EX2200 switches can be interconnected over any of the front-panel uplink ports, the last two ports are configured by default as Virtual Chassis ports, automating deployments when using standard GbE SFP transceivers (sold separately). These two ports can also be configured as GbE uplinks to aggregation devices by disabling the Virtual Chassis technology.
When deployed in a Virtual Chassis configuration, the EX2200 switches elect a master and a backup switch based on a
set of preconfigured policies or criteria. The master switch automatically creates and updates the switching and optional routing tables on all other Virtual Chassis switch members. Switches can be added to or removed from the Virtual Chassis configuration without service disruption.
EX2200 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 EX2200 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.
EX2200 Virtual Chassis configurations implement the same slot/ module/port numbering schema as other Juniper Networks chassisbased 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.

Features and Benefits
High Availability Features
•Redundant Trunk Group (RTG): To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX2200 employs a redundant trunk group to provide the necessary port redundancy and simplify switch configuration.
•Power resiliency through external redundant power supply: The EX2200 supports an optional redundant power supply (RPS) unit which provides power resiliency.
Junos Operating System
The EX2200 runs the same Junos OS used by other Juniper Networks EX Series Ethernet Switches, as well as all of Juniper’s 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 down an entire system.
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.
Converged Environments
The EX2200 provides the highest levels of flexibility and features in its 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 VoIP telephones, closed-circuit security cameras, wireless access points, and other IP-enabled devices, the EX2200 delivers a future proofed solution for converging disparate networks onto a single IP infrastructure. The EX2200 PoE switches also support 802.3at standardsbased PoE+ for powering networked devices like multiple radio IEEE 802.11n wireless access points, and video phones that may require more power than available with IEEE 802.3af.
To ease deployment, the EX2200 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. LLDP-MED-based granular PoE management allows the EX2200 to negotiate PoE usage down to a fraction of a watt on powered devices, enabling more efficient PoE utilization across the switch.
In addition, the EX2200 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 multilevel, end-to-end traffic prioritizations. The EX2200 also support a wide range of policy options, including strict priority, low-latency, and shaped deficit weighted round-robin (SDWRR) queuing.
Security
The EX2200 fully integrates with Juniper Networks Unified Access Control, 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 EX2200 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 policies, QoS policies, or both, or it can mirror user traffic to a central location for logging, monitoring, or threat detection by intrusion prevention systems.
The EX2200 also provides a full complement of integrated port security and threat detection features, including Dynamic Host Configuration Protocol (DHCP) snooping, Dynamic ARP Inspection (DAI), and media access control (MAC) limiting to defend against internal and external spoofing, man-in-the- middle and denial of service (DoS) attacks.
