It is a Distributed Forwarding Card (DFC) that boosts the switching performance of a Cisco Catalyst 6500 or 6800 chassis by allowing line cards to process data locally instead of relying solely on the central supervisor.
It is designed for the Cisco Catalyst 6500 and 6800 series switches, specifically to work with XL-series line cards (such as the 6700 or 6800 modules).
"XL" stands for the "Extra Large" feature set, which means this card supports a much larger routing table and a higher number of network entries, making it ideal for large enterprise or service provider networks.
