EX3200-24T-DC Overview:

The EX3200 line of Ethernet switches offers a high-performance standalone solution for low-density access deployments in the wiring closets of remote offices and small LANs in large office buildings.

High-performance businesses demand high-performance networking solutions. The Juniper Networks EX3200 line of Ethernet switches offer a compact, high-performance solution for supporting today’s converged network access deployments.

The EX3200 line of fixed-configuration switches from Juniper Networks offer a high-performance standalone solution for access-layer deployments in branch and remote offices as well as campus networks.

Featuring complete Layer 2 and Layer 3 switching capabilities, the EX3200 satisfies the wiring closet connectivity requirements of today’s high-performance businesses. Four platform configurations are available offering 24 and 48 10/100/1000BASE-T ports with either full or partial Power over Ethernet (PoE). The base 24- and 48-port EX3200 switches deliver a full 15.4 watts of Class 3 PoE on the first eight ports for supporting networked devices such as telephones, video cameras and wireless LAN (WLAN) access points in converged networks. The EX3200 switches with full PoE deliver 15.4 watts on all 24 or 48 ports to support high-density IP telephony and other converged network environments.

The EX3200 also supports optional four-port Gigabit Ethernet (GbE) and two-port 10 GbE uplink modules with pluggable optics to provide high-speed connectivity to aggregation-layer switches or other upstream devices. A field-replaceable power supply and fan tray minimize mean time to repair (MTTR) for the EX3200, ensuring maximum availability.

Standalone Solution Offering Configuration Flexibility and Field Serviceability

• Optional GbE and 10 GbE uplinks reduce capital costs for remote office deployments
• Field-replaceable power supply and fan tray lower MTTR and increase serviceability
• Single release train for JUNOS Software ensures consistent control plane feature implementation
• Modular JUNOS Software prevents a switch reboot if a single protocol feature fails
• LCD panel provides a simplified interface for device bring-up, recovery and health checking without requiring a console
• Single management interface

The EX3200 offers an integrated Routing Engine (RE) that runs the same modular Juniper Networks JUNOS Software 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 display 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-of-band management, while a rear-panel USB port can be used to easily upload JUNOS Software and configuration files.

 

Features & 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 Software 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 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 Software—routers and switches—to be updated simultaneously with the same software release. All features, new and old, are fully regression-tested, making each new release a true superset of the previous version. Customers can deploy a new JUNOS 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.

JUNOS Software utilizes a single source code, adheres to a consistent and predictable release train, and employs a single modular architecture.

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.

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.

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 CLI management interface offers the same granular capabilities and scripting parameters found in any router powered by JUNOS. 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.
