Ethernet Services Plus Line Cards on Cisco Catalyst 6500 Series Switches Data Sheet
Available Languages
Product Overview
The Ethernet Services Plus (ES+) line cards use an extensible design that allows service prioritization for voice, video, and data services. Service providers and enterprises can benefit from the improved economics, density, advanced quality-of-service (QoS) features, and high performance of these fixed-configuration line cards. With the same basic architecture and features, Ethernet Services Plus Extended Transport (ES+XT) line cards support G.709 framing and Forward Error Correction (FEC) across dense wavelength-division multiplexing (DWDM) networks, enabling optical links to span greater distances.
The ES Plus cards’ programmable interface processors protect network investments and reduce total cost of ownership. The design increases connectivity options and offers superior service intelligence through programmable interface processors operating at line rate. This data sheet contains the specifications for the ES Plus (ES+ and ES+XT) line cards (Figure 1) as supported on the Cisco Catalyst® 6500 Series Switches. This is a subset of the hardware and features supported on the Cisco® 7600 Series Routers.

Designed for interface flexibility and IP-over-DWDM integration in IP and Multiprotocol Label Switching (IP/MPLS) provider edge, WAN and metropolitan area network (MAN) applications, and data center interconnects (DCI), Ethernet Services Plus line cards support up to 40 Gbps of bandwidth with four ports of 10 Gigabit Ethernet interfaces, or 20 Gbps with two ports of 10 Gigabit Ethernet. The cards offer hierarchical QoS (H-QoS), Virtual Private LAN Service (VPLS), Advanced VPLS (A-VPLS) Ethernet over MPLS (EoMPLS), MPLS Layer 3 VPNs (L3VPNs), and full Layer 3 IP/MPLS routing.
The innovative architecture of these industry-leading, premium line cards is designed to deliver cost-effective, high-touch features, combining both application-specific integrated circuit (ASIC) and network processor technologies for an optimal combination of performance and flexibility. The ES Plus line cards provide distributed forwarding with proven ASIC technology in the forwarding path (routing, switching, NetFlow, and access control lists [ACLs]). Additionally, four (for the ES+40 line cards) or two (for the ES+20 line cards) programmable network processors are included in the forwarding plane to enable queuing, shaping, and special packet-processing functions. This technology combination offers customers the necessary flexibility for future service deployments and allows them to scale the system capacity as required.
