The Cisco VS-F6K-PFC4XL is a high-performance Policy Feature Card designed for use with Cisco Catalyst 6500 Series switches, offering advanced traffic management and scalable network services. Built to support large-scale enterprise and service provider environments, this module delivers hardware-accelerated Layer 2–4 policy enforcement, including QoS, access control lists (ACLs), and NetFlow statistics. Its compact design integrates seamlessly into the Catalyst 6500 chassis, optimizing slot space while enhancing overall switch performance. The PFC4XL variant comes with extended memory, enabling support for larger routing and forwarding tables.
Technically, the VS-F6K-PFC4XL supports up to 1 million NetFlow entries and 256,000 hardware entries for ACLs, making it well-suited for high-demand environments. It is compatible with Supervisor Engine 720 and 720-10GE models, leveraging the switch fabric for high-speed packet forwarding. The module supports IPv4 and IPv6 forwarding, multicast replication, and MPLS capabilities, ensuring flexibility for evolving network architectures. Purchasing this unit used can be a cost-effective solution for expanding or upgrading existing Cisco Catalyst 6500 deployments without sacrificing performance or reliability.
