The Cisco Catalyst 6800 Family Switches introduce an 8-port 40-Gigabit Ethernet module designed to handle high-bandwidth needs in next-generation enterprise networks. Built to serve modern campus aggregation and core network deployments, this line card efficiently aggregates high-density 40-Gigabit Ethernet streams to support demanding network infrastructures.
The module operates across enterprise environments by delivering high-throughput performance with hardware-based processing features. It integrates seamlessly into Cisco Catalyst 6807-XL chassis configurations, running on a shared ASIC architecture designed to ensure predictable network delivery, low latency, and efficient data handling.
Product Overview
The line card is offered in two distinct hardware variants to cater to different operational requirements: the Cisco Catalyst 6800 8-Port 40-Gigabit Ethernet Fiber Module non-XL and the Cisco Catalyst 6800 8-Port 40-Gigabit Ethernet Fiber Module XL. Both hardware models share the same fundamental architecture, supporting identical core feature sets in hardware while delivering line-rate performance and oversubscribed operational options per port group.
Each module equips eight 40-Gigabit Ethernet ports utilizing Quad Small Form-Factor Pluggable (QSFP) transceivers and connects to the backplane with up to 160 Gbps of bandwidth in the Catalyst 6807-XL chassis. The hardware features standard front-facing passive UHF RFID technology for streamlined asset management and tracking. Compatibility extends to Supervisor Engine 2T, Supervisor Engine 2TXL, Supervisor Engine 6T, and Supervisor Engine 6TXL models.
Features and Benefits
- High-Bandwidth Density: Provides 8 ports of 40-Gigabit Ethernet per line card using QSFP transceivers, enabling high-density core and aggregation links.
- Distributed Forwarding Architecture: Equipped with the DFC4-E engine to support up to 256K IPv4/MPLS entries, 128K IPv6 entries, 128K MAC addresses, and 64K IPv4/IPv6 multicast routes.
- Advanced Traffic Visibility: Built-in hardware support for 1M NetFlow entries, including Flexible NetFlow, Sampled NetFlow, and Egress NetFlow monitoring.
- Enhanced System Resiliency: Fully supports Virtual Switching System (VSS) topology across all ports to maximize network availability and redundancy.
- Hardware-Based Security: Integrates MACsec (802.1ae), Access Control Lists (ACLs), Security Group Tagging (SGT), and Security Group Access Control Lists (SGACL).
- Quality of Service & Traffic Control: Features hardware-based multicast replication, traffic shaping, and Hierarchical Quality of Service (HQoS) to ensure predictable application performance.
- Integrated Asset Tracking: Uses built-in passive UHF RFID tags on the front panel to enable automated RFID-based inventory management.
- Future-Ready Network Architecture: Compatible with Location ID Separation Protocol (LISP) and Software-Defined Access (SDA) implementations.
Delivering secure and predictable performance for next-generation campus networks
Product Overview
The Cisco Catalyst 6800 Family Switches offer a 8-port 40-Gigabit Ethernet module to serve a variety of high-bandwidth needs for the next-generation enterprise. Working in conjunction with the Catalyst Supervisor Engine 2T/2TXL (VS‑S2T‑10G & VS-S2T-10GXL) or Catalyst Supervisor Engine 6T/6TXL (C6800-SUP6T & C6800-SUP6T-XL), they can serve different needs on campus deployments. The line card includes two variants: the Catalyst 6800 8-port 40-Gigabit Ethernet Fiber Module non-XL and the Catalyst 6800 8-port 40-Gigabit Ethernet Fiber Module XL.
The modules support hardware-based multicast replication, Quality of Service (QoS), Access Control Lists (ACLs), jumbo frames, and low latency to enable secure and predictable performance for bandwidth-intensive applications. Both share a common ASIC architecture and support the same set of features in hardware. The eight-port 40-Gigabit Ethernet Modules can also operate in performance mode. They include hardware features such as Virtual Switching System (VSS), Location ID Separation Protocol (LISP), Security Group Tagging (SGT) and Access Control (SGACL), MACsec (802.1ae), traffic shaping, and Hierarchical Quality of Service (HQoS), Software-Defined Access (SDA) among others. The line cards also have front‑facing passive UHF RFID technology, providing the latest Auto-ID capabilities for asset management. They support Quad Small Form-Factor Pluggable (QSFP) transceivers. The modules are designed to meet the increasing demand for aggregation of 40-Gigabit Ethernet streams in campus deployments, as well as for 40-Gigabit Ethernet transport in the core.
