For service providers who need to simply and cost-effectively scale their Ethernet IP infrastructures in response to growing bandwidth and service demands, the Cisco 12000 Series One-Port 10-Gigabit Ethernet Line Card is the industry's first 10-Gigabit Ethernet solution for high-end routers, delivering a dedicated high-speed 10-Gigabit Ethernet port ideal for intra-point of presence (POP) connectivity and inter-POP connectivity within a metropolitan (metro) region.The Cisco 12000 Series One-Port 10-Gigabit Ethernet Line Card (1-Port 10-GbE) increases the speed of Ethernet connections by a factor of ten, enabling service providers to more cost-effectively scale their distribution networks to higher traffic capacities and simultaneously deliver more sophisticated and higher value services without increasing complexity.Supported by the Cisco 12000 Series distributed system architecture, the 1-Port 10-GbE Line Card provides one dedicated 10-Gigabit Ethernet port that offers 10-Gigabits-per-second (Gbps) line-rate performance for IP and Multiprotocol Label Switching (MPLS) traffic. This interface operates in all Cisco 12400 Series Internet Routers, offering service providers platform flexibility in architecting their networks.The 1-Port 10-GbE Line Card supports an advanced feature set and maintains performance when features are enabled as a result of the dedicated Layer 3 forwarding application-specific integrated circuit (ASIC) and advanced memory components. The extensive 1-Port 10-Gbe Line Card feature set includes industry-leading quality of service (QoS) features ideal for maintaining customer service-level agreements (SLAs), extended access control lists (ACLs) to address security risks, a comprehensive set of MPLS features for high-level services to customers, and Ethernet features such as virtual LANs (VLANs), source and destination Media Access Control (MAC) accounting, and jumbo frames.
