Designed for delivering flexible transport Ethernet services in IP/MPLS provider edge networks, as well as WAN/MAN and optical transport network (OTN) applications, the Cisco 7600 series Ethernet Services Plus Transport Line Cards support port densities of 40 Gbps in 10 Gigabit Ethernet and Gigabit Ethernet port varieties. The cards feature hierarchical quality of service (QoS) supporting 16 queues per physical port, locally significant VLANs, and up to 16,000 VLAN IDs per line card for rich services at scale. The 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, Virtual Private LAN Services (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 architecture of these industry-leading, premium Ethernet services line cards is designed to deliver cost-effective high-touch features, combining both ASIC and network processor technology for optimal performance and flexibility. The Cisco 7600 series ES Plus Transport Line Cards provide distributed forwarding with proven ASIC technology in the forwarding path (routing, switching, NetFlow, ACLs) and queuing and shaping functions to optimize the performance of these foundational features.
