EX9200 Overview:

The EX9200 line of Ethernet switches provides a programmable, flexible, and scalable foundation for delivering mission-critical applications in enterprise campus and data center core environments.

EX9200 switches simplify the deployment of cloud applications, server virtualization, and rich media collaboration tools in enterprise campus and data center core and aggregation environments.

In the enterprise campus, the EX9200 enables collaboration and provides simple and secure access for the delivery of mission-critical applications. In the data center, it simplifies operations to align the network with fast-changing business requirements.

The EX9200 switches also serve as the foundation for the Junos Fusion Enterprise architecture, a new standards-based approach for creating an open, highly scalable switch fabric for the enterprise campus. Junos Fusion Enterprise dramatically simplifies campus deployments by collapsing the entire network into a single management point, with the EX9200 as its core. Junos Fusion Enterprise can also serve as the shared core for enterprise campus environments that have on-premise data centers.

Three EX9200 switches are available: the EX9204, EX9208, and EX9214. The EX9200 chassis deliver up to 240 Gbps (full duplex) per slot. A pass-through midplane design supports capacity of up to 13.2 Tbps for built-in migration to next-generation deployments. Any combination of 1GbE, 10GbE, and 40GbE interfaces can be used, and the switches include support for 100GbE cards when available.

Architecture and Key Components:

The EX9200 campus and data center core Ethernet switches share a number of architectural elements. The Routing Engines employed by these switches run Junos OS, which processes all Layer 2 and Layer 3 protocols, while the Switch Fabric modules manage the chassis and provide switching functionality for data traffic coming from line cards.

The EX9200 line cards, which are common across all EX9200 platforms, include Packet Forwarding Engines (PFEs) that process network traffic, as well as a line-card processor that provides scalable local control.

In the data center, the EX9200 architecture is designed for very large deployments, with no head-of-line blocking, a single tier low latency switch fabric, efficient multicast replication handling, and deep buffering to ensure performance at scale. The EX9200 chassis midplane distributes the control and management signals over independent paths to the various system components and distributes power throughout the system. Data plane signals pass directly from the EX9200 line cards to the EX9200 Switch Fabric modules via a unique pass-through connector system that provides unparalleled signal quality for future generations of fabric ASICs.

To maintain uninterrupted operation, the EX9200’s fan trays cool the line cards, Routing Engine, and Switch Fabric modules with redundant, variable speed fans. In addition, the EX9200 power supplies convert building power to the internal voltage required by the system.

All EX9200 components are hot-swappable, and all central functions are available in redundant configurations, providing high operational availability by allowing continuous system operation during maintenance or repairs.

Junos Fusion Enterprise

Junos Fusion Enterprise technology enables a large number of devices deployed throughout a building to be managed as a single, logical device. Junos Fusion Enterprise reduces network complexity, simplifies network management, and reduces overall operational costs by allowing network administrators to connect up to 128 EX4300, EX3400, or EX3200 access switches with up to two EX9200 Ethernet switches to form a high-port density device that appears to the larger network as a single switch. A Junos Fusion Enterprise deployment has a single point of management—the EX9200 switch serving in the aggregation device role—that runs Junos OS and is responsible for configuring, monitoring, and maintaining all devices in the topology (see Figure 1).

Junos Fusion Enterprise is currently supported on the EX9200- RE, EX9200-40T, EX9200-32XS, and EX9200-6QS. Additional line cards will be supported in a future software release.

EX9200 Line Cards

EX9200 Line Cards

The EX9200 line cards support an extensive set of Layer 2 and Layer 3 services that can be deployed in any combination of L2- L3 applications.

Each EX9200 line card is built upon Juniper One custom silicon, which supports a wide range of Layer 2 and Layer 3 Ethernet functionality including 802.1Q VLAN, link aggregation, Virtual Router Redundancy Protocol (VRRP), L2 to L3 mapping, and port monitoring. Additionally, the line cards support filtering, sampling, load balancing, rate limiting, class of service (CoS), and other key features needed for the deployment of dependable, highperformance Ethernet infrastructure.

EX9200 Routing Engine

The EX9200 switch’s Routing Engine is based on the same fieldproven hardware architecture used by Juniper Networks routers, bringing the same carrier-class performance and reliability to the EX9200 that Juniper routers bring to the world’s largest service provider networks. The RE’s central CPU performs all system control functions and maintains hardware forwarding table and routing protocol states for the EX9200. Dedicated hardware on the RE supports chassis management functions such as environmental monitoring. Communication between RE modules and individual line cards takes place over a dedicated internal GbE out-of-band control interface.

There are two EX9200 Routing Engines: the EX9200-RE and EX9200-RE2. The EX9200-RE supports control and management plane functionality with an integrated Routing Engine that features a quad-core, 1.73 GHz Intel processor with 16 gigabytes of DRAM and dual front pluggable SSDs, each providing 32 GB of storage for Junos OS images and logs.

The EX9200-RE2 features a six-core, 2 GHz Intel processor with 64 gigabytes of DRAM and dual front-pluggable SSDs, each providing 64 GB of storage for Junos OS images and logs. The 10GbE Routing Engine-to-switch fabric interface will allow running virtualized applications in the future.

Both Routing Engines feature AUX, console, and Ethernet ports on the front panel to support out-of-band system management and monitoring, while an external USB port accommodates a removable media interface for manually installing Junos OS images. Junos Fusion Enterprise will be supported on the EX9200- RE2 in a future release.

EX9200 Switch Fabric

The EX9200 Switch Fabric modules are hot-swappable and serve as the central non-blocking matrix through which all network data passes.

Two EX9200 Switch Fabric modules are available: the EX9200- SF and EX9200-SF2. The EX9200-SF supports up to 240 Gbps throughput per slot, while the EX9200-SF2 supports 480 Gbps throughput per slot. See Table 2.

Table 2: EX9200 Switch Fabric Module Throughput per Slot

Switch Fabric Module With Fabric Redundancy Without Fabric
EX9200-SF Up to 250 Gbps Up to 260 Gbps
EX9200-SF2 Up to 480 Gbps Up to 480 Gbps

On the EX9204 and EX9208 switches, two Switch Fabric modules deployed in a redundant configuration deliver up to 480 Gbps system throughput per slot. The Switch Fabric module installed first functions as the master, while the second serves as a backup.

On the EX9214, three Switch Fabric modules deployed in a redundant configuration deliver 480 Gbps system throughput per slot. Traffic is load-balanced across the first two Switch Fabric modules installed, which together function as the master switch fabric, while the third serves as a backup.

Switch Fabric modules perform the following key functions:

  • Monitoring and controlling system functions
  • Interconnecting all line cards
  • Clocking and system resets
  • Acting as Routing Engine carrier

Power

Each EX9200 chassis contains four power supply bays to provide complete flexibility for provisioning and redundancy. The power supplies connect to the midplane, which distributes the different output voltages produced by the power supplies to the switch components, depending on their voltage requirements. Each power supply is cooled by its own internal cooling system. All EX9200 chassis support both AC and DC power supplies; however, AC and DC supplies cannot be mixed in the same chassis.

Features & Benefits:

Simplified Network Architectures

The EX9200 is ideal for simplifying campus, data center, and combined campus and data center network environments by collapsing network layers.

In the campus, the EX9200 collapses the core and distribution layers; when used with Juniper access layer switches deployed in an MC-LAG configuration, the EX9200 helps eliminate Spanning Tree Protocol, dramatically simplifying the network architecture and network operations.

Similarly, in the data center the EX9200 can be used to collapse core and aggregation layers; again, when used with Juniper access switches in an MC-LAG configuration, the EX9200 helps reduce the number of managed devices by more than 50% and eliminates Spanning Tree Protocol from the network.

In combined campus and data center environments, the EX9200 consolidates network layers to simplify the network architecture and operations.

In all scenarios, the EX9200 delivers a simple, secure, virtualized network environment that increases enterprise business agility.

High Availability

EX9200 core switches deliver a number of high availability features that ensure uninterrupted, carrier-class performance. Each EX9200 chassis includes an extra slot to accommodate a redundant Routing Engine module which serves as a backup in hot-standby mode, ready to take over in the event of a master Routing Engine failure. If the master fails, the integrated L2 and L3 graceful Routing Engine switchover (GRES) feature of Junos OS, working in conjunction with the nonstop active routing (NSR) and nonstop bridging (NSB) features, ensures a seamless transfer of control to the backup, maintaining uninterrupted access to applications, services, and IP communications.

Carrier-Class Operating System

The EX9200 line of switches runs the same Junos OS used by all other Juniper Networks EX Series Ethernet Switches, as well as the Juniper Networks routers that power the world’s largest and most complex networks.

By using 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 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.

Simplified Management and Operations

A range of system management options are available for the EX9200 line of switches as well.

The standard Junos OS CLI provides the same granular management capabilities and scripting parameters found in all Junos OS-powered devices. In addition, integrated Junos XML management protocol tools provide early detection and automatic resolution of potential problems related to the operating system.

Juniper Networks Junos Space software provides system-level management across all EX Series Ethernet Switches, as well as other Juniper products deployed throughout the network—all from a single console.

MACsec

The EX9200-40F-M and EX9200-20F-MIC line cards support IEEE 802.1ae MACsec with AES-128 bit encryption, providing support for link-layer data confidentiality, data integrity, and data origin authentication. The EX9200-40XS line card currently supports AES-128 bit encryption; AES-256 bit encryption will be enabled in software in a future release. A single EX9200-SFL license is required for the EX9200 chassis in order to enable MACsec in software.

Defined by IEEE 802.1AE, MACsec provides secure, encrypted communication at the Link Layer that is capable of identifying and preventing threats from denial of service (DoS) and other intrusion attacks, as well as man-in-the-middle, masquerading, passive wiretapping, and playback attacks launched from behind the firewall. When MACsec is deployed on switch ports, all traffic is encrypted on the wire, but traffic inside the switch is not. This allows the switch to apply all network policies such as QoS, deep packet inspection and sFlow to each packet without compromising the security of packets on the wire.

Hop-by-hop encryption enables MACsec to secure communications while maintaining network intelligence. In addition, Ethernet-based WAN networks can use MACsec to provide link security over longhaul connections. MACsec is transparent to Layer 3 and higher-layer protocols and is not limited to IP traffic; it works with any type of wired or wireless traffic carried over Ethernet links.

Scale Licenses

EX9204-ML, EX9208-ML, and EX9214-ML Mega Scale license SKUs enable an EX9200 chassis to support 512K FIB and ARP entries. Only one ML license is required per chassis.
