This module houses a single forwarding engine, capable of delivering IPv4 throughput up to 60 million packets per second (Mpps), indicating its ability to handle significant network traffic with ease. In terms of forwarding capacity, the module supports up to 256K IPv4 forwarding entries, 256K MPLS forwarding entries, and 128K IPv6 forwarding entries, providing extensive routing capabilities. Additionally, it can maintain up to 64K IPv4 and IPv6 multicast routes, offering robust support for multicast applications. The module also accommodates 64K Access Control List (ACL) entries and 512K NetFlow entries, enabling comprehensive network monitoring and security features. With a MAC address table capacity of 128K and the ability to support 16K bridge domains, the Cisco C6800-8P10G is well-suited for large-scale deployments. It also features advanced queuing mechanisms, including 1p7q4t (one priority queue, seven data queues, and four thresholds) for both receive and transmit directions, ensuring efficient traffic management.
  • Class of Service (CoS) based Queue Mapping and Differentiated Service Code Point (DSCP) based Queue Mapping allow for precise traffic prioritization.
  • Ingress and egress queuing methods include Deficit Weighted Round Robin, Shaped Round Robin, and Class Based Weighted Fair Queuing, enhancing the module’s ability to manage diverse traffic types efficiently.
  • The module is equipped with generous port buffers, comprising 500 MB per port for egress and 2.5 MB per port for ingress, facilitating smooth traffic flow and reducing packet drops.
Moreover, the Cisco C6800-8P10G supports hardware multicast replication in both ingress and egress modes, with approximately 20 Gbps per replication engine and four engines per module, effectively distributing multicast traffic. It also offers jumbo frames support up to 9216 bytes, catering to networks requiring large frame sizes for specialized applications. Equipped with 2 GB of onboard memory, this module is capable of handling complex network operations and maintaining extensive routing tables, further enhancing its performance in multi-service environments. The Cisco C6800-8P10G is designed to meet the needs of networks demanding high throughput, extensive routing capabilities, and efficient traffic management, making it an essential component for modern high-capacity networks.
