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.


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 10-inch 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 high-speed 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.


Features and benefits

In this section we discuss the features and benefits.


High-availability features

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.

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.

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 solution for converging disparate networks onto a single IP infrastructure. The EX2200 PoE switches also support 802.3at standards-based PoE+ for powering networked devices like multiple radio IEEE 802.11n wireless access points, and video phones that might 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.

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 supports a wide range of policy options, including strict priority, low-latency, weighted random early detection (WRED), 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 and Layer 2 - 4 policy enforcement based on user identity, location, and 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.


Simplified management and operations

The EX2200 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 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 pre-installed on a flash drive and used to boot the EX2200 at any time.

Another feature, called automatic software download, enables network administrators to easily upgrade the EX2200 using the DHCP message exchange process to download and install software packages. Users simply configure the automatic software download feature on EX2200 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.

Four system management options are available for the EX2200 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 EX2200 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.

When managing a group of EX2200 switches, the Network and Security Manager provides system-level management across all Juniper Networks switches in the network from a single console.

Finally, EX2200 fault, configuration, and performance data can be exported to leading third-party management systems such as IBM Tivoli and Computer Associates Unicenter software, providing a complete, consolidated view of network operations.
