PFC/DFC - is the customer facing name for the L2 and L3/L4 forwarding engines on the 6500. EARL x - is the internal name used to refer to the L2 and L3/L4 forwarding engine, x being the generation of the forwarding engine. EARL generation and PFC/DFC versions do not directly match, but map as follows EARL PFC/DFC 5 PFC Supervisor 1A 6 PFC2 / DFC Supervisor 2 7 PFC3 / DFC3 Supervisor 720 Depending upon the features and the availability of particular ASIC processes the forwarding engine has ranged from four ASICs to a single ASIC. The exact number varies from generation to generation, and even within revisions within a generation.
