7600 Series Ethernet Services 20 Gbps (ES20) Line Cards utilize an extensible design that
enables service prioritization for voice, video, data, and wireless mobility services. Service provider and
enterprise customers benefit from the improved economics, density, advanced Carrier Ethernet features,
and the high performance of the ES20 fixed-configuration line cards.
The ES20 programmable interface processors protect network investments and reduce total cost of
ownership. The design maximizes connectivity options and offers superior service intelligence through
programmable interface processors operating at line rate. This data sheet contains the specifications for
the Cisco 7600 ES20 Line Cards as shown in Figure 1.

Product Overview
Designed for Carrier Ethernet, IP/Multiprotocol Label Switching (MPLS) Provider Edge in mid-size and smaller
service provider and enterprise WAN applications, the Cisco 7600 Series Ethernet Services 20G (7600-ES20)
supports up to 20 Gbps of bandwidth with 20 ports of Gigabit or 2 ports of 10 G Ethernet interface models. The cards
feature hierarchical quality of service (QoS), locally significant VLANs, and up to 16 K VLAN IDs per line card for rich
services at scale. The 7600-ES20 Line Cards provide the unique ability to combine both Layer 2 and Layer 3
services on the same line card. The combination of native Ethernet Layer 2 switching, bridging, VPLS, Ethernet over
MPLS (EoMPLS), and Layer 3 IP/MPLS routing distinguishes this line card among other products on the market,
particularly in Carrier Ethernet applications.
The innovative architecture of these industry-leading, premium Ethernet services line cards is designed to deliver
cost-effective, high-touch features, combining both application-specific integrated circuit (ASIC) and Network
Processor technology for an optimal combination of performance and flexibility. The 7600-ES20s provide distributed
forwarding with proven ASIC technology in the forwarding path (routing, switching, Netflow, access control lists
[ACLs]), as well as for queuing and shaping functions to provide the maximum performance for these foundational
features. Additionally, two (2) programmable network processors are included in the forwarding plane to facilitate
flexibility and feature growth. This ideal technology combination provides customers with the necessary flexibility for
future service deployments and allows them to scale the system capacity as required.
