Product Review

The Cisco C6800-SUP6T provides substantial scalability for network expansion with support for up to 256K IPv4 routes, 128K IPv6 routes, and 4K VLANs, catering to large and complex network environments. However, its onboard memory is limited to 4GB and ingress/egress buffers may be insufficient for high-bandwidth applications, potentially impacting performance in data-intensive scenarios. Additionally, the hardware-assisted Network Address Translation and comprehensive support for up to 390 Mpps in IPv6 routing, VPLS, and GRE make it a versatile choice for diverse networking requirements.


The Cisco C6800-SUP6T is a state-of-the-art supervisor engine designed to deliver high-performance, scalable, and flexible networking solutions. It is engineered to support a wide range of applications, including enterprise core distribution layers and data center networking requirements. This product overview focuses on the hardware specifications of the Cisco C6800-SUP6T, highlighting its capabilities in handling extensive networking demands. At the core of the Cisco C6800-SUP6T's capabilities is its support for up to 128K MAC entries, enabling the device to efficiently manage a large number of connected devices. It further supports 256K IPv4 routes and 128K IPv6 routes, ensuring comprehensive coverage across both protocol versions. For security and quality of service (QoS), it offers 64K Access Control List (ACL) entries, shared between QoS and security features. The engine is also capable of handling 512K NetFlow entries, facilitating detailed network traffic analysis. The Cisco C6800-SUP6T excels in multicast routing, with support for up to 128K IPv4 and IPv6 multicast routes. This feature is crucial for applications requiring efficient data distribution across multiple destinations. IPv6 routing performance is remarkable, reaching up to 390 million packets per second (Mpps), while Layer 2 bridging can handle up to 780 Mpps. The supervisor engine also supports jumbo frames up to 9216 bytes, beneficial for reducing overhead in large data transfers. Key specifications include: - VLAN support for up to 4K VLANs, allowing for extensive network segmentation. - Support for up to 16K bridge domains, enhancing network flexibility and scalability. - Capability to handle up to 8192 Virtual Routing and Forwarding (VRF) instances, ensuring efficient traffic segregation and management. The device's logical interface capacity stands at 128K, with an 8-bit EtherChannel hash function, optimizing bandwidth through load balancing. For high-speed transport technologies, it supports Virtual Private LAN Service (VPLS) and Generic Routing Encapsulation (GRE) up to 390 Mpps. Network Address Translation (NAT) is hardware-assisted, ensuring efficient IP address translation with minimal performance impact. Onboard memory is ample at 4 GB, paired with ingress buffers of 1.25 MB per 10-Gb port in 2:1 mode and 2.5 MB per 10-Gb port in 1:1 mode. Egress buffers are equally impressive at 250 MB per 10-Gb port in 2:1 mode and 500 MB per 10-Gb port in 1:1 mode. This buffering capacity ensures smooth handling of bursty traffic, mitigating packet loss. For traffic management, the Cisco C6800-SUP6T offers 16,348 aggregate traffic rate limiting policers and 20 ingress plus 6 egress Layer 2 rate limiters. Port security features are included, providing basic protection against unauthorized access. In conclusion, the Cisco C6800-SUP6T supervisor engine is equipped with a comprehensive set of features designed to meet the demands of modern network environments. Its support for extensive MAC entries, IPv4 and IPv6 routes, ACL entries, and high-performance routing and bridging capabilities, along with robust memory and buffering capacities, make it an excellent choice for enterprises and data centers looking to scale their network infrastructure.
