Cisco MEM-XCEF720-512: Catalyst 6500 512MB DDR memory for xCEF720 (67xx, DFC3A/DFC3B).

The Cisco MEM-XCEF720-512 is a 512MB DDR memory module for the Catalyst 6500 xCEF720-based line card family, fitted to 67xx-series interface modules equipped with a Distributed Forwarding Card (DFC3A or DFC3B). The DFC performs local Layer 2/3 forwarding decisions on the line card itself rather than relying solely on the supervisor engine, and this memory module supports the DFC’s forwarding table and CEF (Cisco Express Forwarding) tables at higher route-table scale. It is a routine upgrade or replacement part on Catalyst 6500 chassis carrying distributed-forwarding-capable line cards, particularly in networks where route-table growth has outgrown the default memory allocation. Tech-Star (UK-based, shipped worldwide) supplies Cisco memory upgrades. Confirm your specific 67xx line card and DFC3A/DFC3B revision before ordering.
