Juniper Networks EX8200-48T Ethernet Line Card

EX8200-48T Overview:

The EX8200-48T Ethernet line card offers 48 10/100/1000BASE-T ports with RJ-45 copper connectors. Designed for data center end-of-row server access, or campus applications where high densities, high performance, and high availability over copper links 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.

Juniper Networks EX8200 Ethernet line cards offer a variety of interfaces for supporting high-density 10/100/1000BASE-T, 100BASE-FX/ 1000BASE-X, and 10-Gigabit Ethernet deployments. Working with the Juniper Networks EX8208 Ethernet Switch eight-slot and the Juniper Networks EX8216 Ethernet Switch 16-slot modular chassis, the EX8200 Ethernet line cards offer a variety of flexible, high-density interfaces for high-performance data center and campus aggregation and core environments.

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 and campus aggregation and core environments, as well as high-performance service provider interconnects.

EX8200 Ethernet line cards are specifically designed to optimize enterprise applications. Each EX8200 Ethernet line card features an on-board Packet Forwarding Engine—the EX-PFE2—that is equipped with two purpose-built, application-specific integrated circuits (ASICs), one to perform wire-speed packet processing at line rates, and another to perform internal deep packet queuing and buffering while providing a high-speed interface to the chassis switch fabric. In addition, each line card contains a local processor which provides scalable local control and status processing.

Features & 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 control list) filtering, marking, and rate limiting also occur at wire rate, with up to 64,000 entries across L2-L4 packet headers that can be applied per port, per VLAN, and per routed interface.

The packet processor ASIC also supports generic routing encapsulation (GRE) tunneling and two-label MPLS in hardware at line rate. Additional packet processor ASIC capabilities include multiple queues for CPU-bound control traffic to protect the Routing Engine from denial of service (DoS) attacks, with support for up to seven mirrored analyzer sessions directed to individual ports, VLANs, or tunneled interfaces.

The switch fabric interface ASIC of the EX-PFE2 manages the large ingress and egress buffers that provide congestion avoidance and traffic prioritization. On ingress, each switch fabric interface queues packets based on destination using dedicated high- and low-priority buffers for each wire-speed, 10-Gigabit Ethernet egress port, or each group of 12 Gigabit Ethernet ports in the system. These weighted random early detection (WRED) virtual output queues—up to 8,192 in an EX8216 chassis—prevent “head-of-line blocking” among ports on the same line card, ensuring complete independence of traffic flows among all 10-Gigabit Ethernet ports in the system.

The switch fabric interface also manages the transfer of data across the distributed, single-tier crossbar switch fabric. Data is evenly distributed across the fabric to balance traffic load and ensure graceful degradation of performance in the event of a non-redundant switch fabric failure. Multicast traffic is also balanced across the system using the same line-rate, binary-tree replication process as the Juniper Networks T Series Core Routers and the Juniper Networks MX Series Ethernet Services Routers, minimizing fabric congestion while reducing latency.

On egress, the switch fabric interface provides eight dedicated queues per port, mapped according to class of service (CoS) or DiffServ code point (DSCP) values. A WRED scheduler is used for congestion avoidance within each queue, while administrator-configured strict and weighted round-robin priority options are available between queues on a single port. Multicast traffic is managed independent of unicast traffic.

Total buffer size is 512 MB on each EX8200-8XS 10-Gigabit Ethernet port, and 42 MB on each EX8200-48T and EX8200-48F Gigabit Ethernet port, providing 50-100 ms of bandwidth delay buffering. These deep buffers and ingress and egress queuing mechanisms are critical to managing mission-critical data, handling bursty traffic, and reducing latency at the application level to free up bandwidth 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.

Up to 255 link aggregation groups (LAGs) are supported, ensuring that the large number of high-density Gigabit Ethernet LAGs found in campus and data center core and aggregation deployments can be accommodated. Up to 12 ports may be bundled into a single 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 chassis’ redundant Routing Engines over dedicated internal gigabit control-plane links. This CPU manages the local line card components, distributes forwarding table and other control plane data from the Routing Engine to the local EX-PFE2 ASICs, and returns line card status and CPU-directed control plane packets to the Routing Engine. A second processor resident on each line card aggregates flow-based statistics and analyzes sampled packets without impacting control plane performance. Finally, hot insertion and removal of all line cards is supported for online maintenance and support.
