Product Description
The Juniper Networks® EX8200 line of Ethernet switches offer powerful, modular
platforms that deliver the performance, scalability, and carrier-class reliability required for
today’s high-density enterprise data center access and core and campus aggregation and
core environments, as well as high-performance service provider interconnects.

Four versions of the EX8200 Ethernet line cards are available, each of which supports
a consistent set of features and capabilities: the EX8200-48T, the EX8200-48F, the
EX8200-8XS and the EX8200-40XS.
EX8200-48T: The EX8200-48T Ethernet line card offers wire-rate 48
10/100/1000BASE-T ports with RJ-45 copper connectors. Designed for data center endof-row server access, or campus applications where high densities, high performance, and
high availability over copper links of up to 100 m are required, the EX8200-48T enables up
to 384 line-rate ports in a single EX8208 chassis, or 768 ports in an EX8216 chassis.
EX8200-48F: The EX8200-48F is a 48-port wire-rate 100BASE-FX/1000BASE-X line
card with modular small form-factor pluggable transceiver (SFP) interfaces for supporting
a wide range of 100 Mbps or Gigabit Ethernet optical connections over multimode fiber,
single-mode fiber, or copper cabling. Designed for high-performance enterprise and
service provider distribution applications, the EX8200-48F also enables up to 384 linerate ports in an EX8208 chassis, and 768 ports in an EX8216 chassis.
EX8200-8XS: The EX8200-8XS is an eight-port 10GBASE-X line card with compact,
modular SFP+ fiber optic interfaces, enabling up to 64 line-rate 10-Gigabit Ethernet
ports in an EX8208 chassis and 128 ports in an EX8216 chassis. The EX8200-8XS is
ideal for enterprise applications such as campus or data center uplink aggregation,
core and backbone interconnects, and for service provider deployments requiring high-

Features and Benefits
The EX8200 PFE2 complex is comprised of two ASICs: the packet
processor and the switch fabric interface. The hardware pipeline
on the packet processor ASIC supports approximately 960 Mpps
of Layer 2 and Layer 3 IPv4 and IPv6 traffic in the EX8208, and
more than 1900 Mpps in the EX8216. Wire-speed performance
is maintained regardless of packet size, from 64- to 9216-byte
jumbo frames across both L2 and L3 interfaces. Firewall (access
and limiting TCP/IP retries at the application level to free up
bandwidth, reduce latency and allow a higher quantity of both
unicast and multicast application flows across the network.
All packets pass through the entire EX-PFE2 ingress pipeline, the
switch fabric, and the EX-PFE2 egress pipeline. This consistency
of packet processing ensures that the EX-PFE2 is capable of
delivering port-to-port latencies of under 10 μs, regardless of
ingress or egress port location.

The packet processor ASIC also supports generic routing

LAG, allowing 120 Gbps logical interfaces to be created using a full
L2-L4 hash algorithm for optimal load balancing. Ports in a LAG
may be distributed across line cards within an EX8200 switch for
an added level of resiliency. Automatic detection, recovery, and
redistribution of LAG traffic in the event of a port, link, or line card
failure is supported for highly reliable connections.
Each line card contains a local CPU that is connected to the
