The Cisco Nexus 7000 F2-Series Module is built with switch-on-chip (SoC) architecture, in which a single ASIC implements all the module functions: from ingress buffering, to forwarding lookups and access control lists (ACLs) and quality-of-service (QoS) tables, to fabric interfaces and virtual output queuing (VOQ). Each SoC manages four front-panel interfaces. This type of design increases performance while lowering the power and cooling requirements of the module.
