Product Description
The eight-slot Juniper Networks® EX8208 Ethernet Switch, part of the Juniper Networks
EX8200 line of Ethernet Switches, is ideal for aggregating access switches such as Juniper
Networks EX3200 and EX4200 lines of Ethernet switches deployed in campus wiring
closets and in data center top-of-rack applications. The EX8208 is also designed to
support 1-Gigabit and 10-Gigabit Ethernet server access in data center end-of-row chassis
deployments. In core applications, the EX8208 provides approximately 960 Mpps of highdensity, wire-speed 10-Gigabit Ethernet performance for the largest campus and data
center networks.
Customers can advance the economics of their network by leveraging the consistent
performance of the Juniper Networks EX8200 line of Ethernet switches’ wire-speed line
cards, in conjunction with the EX4500, EX4200, EX3200 and EX2200 lines of Ethernet
switches and Juniper Networks Junos® operating system to reduce capital and operational
expenses across the network infrastructure.
solution for the high-performance
EX8208 Ethernet Switch
networks of today and into the future.
The EX8208 switch includes an advanced set of hardware features enabled by Juniperdesigned EX-PFE2 ASICs and the carrier-class Juniper Networks operating system, Junos
OS, delivering the capabilities needed to support the high-performance networks of today
and tomorrow.
The EX8208 switch features eight dedicated line-card slots that can accommodate a
variety of EX8200 Ethernet line cards. Options include the following:
• EX8200-48T: a 48-port 10/100/1000BASE-T RJ-45 unshielded twisted pair (UTP)
line card
• EX8200-48F: a 48-port 100BASE-FX/1000BASE-X SFP fiber line card
• EX8200-8XS: an eight-port 10GBASE-X SFP+ fiber line card
• EX8200-40XS: a 40-port 10GBASE-X SFP+ / 1000BASE-X SFP line card
Fully configured, a single EX8208 chassis can support up to 384 Gigabit Ethernet or 64
10-Gigabit Ethernet ports at wire speed, or 320 10-Gigabit Ethernet ports in shared bandwidth
applications, delivering one of the industry’s highest 10-Gigabit Ethernet port densities.
At 14 rack-units (RUs) high, three EX8208 Ethernet Switches can
fit in a standard 42 RU rack, enabling up to 1,152 Gigabit Ethernet
or 960 10-Gigabit Ethernet ports in a single rack. At just 21 inches
deep, the EX8208 is sufficiently compact to fit into typical wiring

with up to 12 10GbE line-rate links. Since the Virtual Chassis intraconnections use small form SFP+ interfaces, Virtual Chassis
member switches can be separated by distances of up to 40 km.
If the EX8200 Virtual Chassis switch members are located in the
same or adjacent racks, low cost direct attach cables (DACs) can
be used as the interconnect mechanism.
Since the network fabric created by an EX8200 Virtual Chassis
configuration prevents loops, it eliminates the need for protocols
such as Spanning Tree. The fabric also simplifies the network
by eliminating the need for Virtual Router Redundancy Protocol
(VRRP), increasing the scalability of the network design. In
addition, since the Virtual Chassis Control Protocol (VCCP) used
to form the EX8200 Virtual Chassis configuration does not affect
the function of the control plane, Junos OS control plane protocols
such as 802.3ad, OSPF, Internet Group Management Protocol
(IGMP), Physical Interface Module (PIM), BGP and others running
on an EX8200 Virtual Chassis system behave in exactly the same
way as when running on a standalone chassis.
XRE200 External Routing Engine
In an EX8200 Virtual Chassis configuration, the Routing Engine
functionality is externalized to a purpose-built, server-class
appliance, the XRE200, which supports control plane processing
requirements for large-scale systems and provides an extra layer
of availability and redundancy.
All control protocols such as OSPF, IGMP, Link Aggregation Control
Protocol (LACP), 802.3ah and VCCP, as well as all management
plane functions, run or reside on the XRE200. Junos OS high
availability (HA) features can be enabled on the two XRE200s
required in a redundant EX8200 Virtual Chassis configuration. In
the event of an active XRE200 failure, the standby XRE200 takes
over and Junos OS HA features ensure that the state of the Virtual
Chassis, L2/L3 protocols, and forwarding information are not lost.
See the XRE200 data sheet for more information.

Switch Fabric and Routing Engine (SRE) Module
The EX8208 SRE module performs two functions: it incorporates
switch fabric, control plane, and management plane functionality
on a single module, and it includes an integrated Routing Engine
featuring a 1.2 GHz processor with 2 gigabytes of DRAM and 2
gigabytes of Flash storage. A dedicated front-panel RJ-45 Gigabit
Ethernet port on the SRE module supports out-of-band system
management and monitoring, while an external USB port allows
replaceable, enabling failed units to be easily replaced without
service interruption.
The two active, load-sharing switch fabrics on the SRE and Switch
Fabric modules collectively deliver up to 320 Gbps (full-duplex)
of packet-data bandwidth per line-card slot, providing sufficient
capacity to support future 100-Gigabit Ethernet deployments.

W at low-line (15 A at 100-120 V) to the chassis. The EX8208
also supports a 3000 W power supply for high-line operation.
A redundant-input 2000 W DC power supply is also available
for central office deployments. The EX8200 power supplies
are more than 90 percent efficient at a wide range of loads,
minimizing building power requirements and reducing overall power
consumption. These power supplies are interchangeable across the
EX8200 line, simplifying maintenance and sparing.
The EX8208 switch features an extra slot to accommodate a
second SRE module, providing N+1 redundancy. When a second
SRE module is present, the integrated Routing Engine serves as a
backup in hot standby mode, ready to take over in the event of a
master RE failure. Should the master fail, an integrated Layer 2 and
Layer 3 Graceful Route Engine Switchover (GRES) feature seamlessly
transfers control to the backup, maintaining uninterrupted access to
applications, services, and IP communications.

Simplified Management and Operations
A range of system management options are available for the
EX8208 switches.
The standard Junos OS CLI provides the same granular
management capabilities and scripting parameters found in all
Junos OS-based products. The EX8208 switches also include
the integrated J-Web management tool, an embedded device
manager that allows users to configure, monitor, troubleshoot,
and perform device-level maintenance on individual switches
via a browser-based graphical interface. In addition, integrated
JUNOScript Automation tools provide early detection and
automatic resolution of potential problems related to the
operating system.
The Juniper Networks Network and Security Manager (NSM)
software provides system-level management across all Juniper
Networks EX Series Ethernet Switches, as well as other Juniper
Networks products deployed throughout the network, all from a
single console.
Performance data from EX8208 switches can also be exported to
leading third-party management systems such as HP OpenView,
IBM Tivoli, and Computer Associates Unicenter, where it is
combined with management data from other network components
to provide a complete, consolidated view of network operations.
In addition, the EX8200 line of Ethernet switches support the Juniper
Networks Advanced Insight Solutions (AIS), a comprehensive set of
tools that enable Juniper Networks J-Care Technical Service offerings
to automate the delivery of tailored, proactive network intelligence
and support services to specific products.
