The Cisco Supervisor Engine serves as the management card for modular Cisco switches that can also, in some cases, act as forwarding/routing element.[1]
Over time, the Supervisor Engine has undergone multiple iterations and was different for different modular switches in Cisco Portfolio (Catalyst 4000, 4500, 5000, 5500, 6000, 6500, 9400, 9600 and Nexus switches).
Supervisor Engine typically offers management of entire chassis in modular system, control over its power (PSU, Power Supply Units), cooling (fans) and physical management interfaces, as well as Line Cards (LCs) that host its own physical interfaces to serve user traffic.
Some models of Supervisor Engines can also process traffic, albeit at reduced scale and speed. Typically, traffic processing is distributed to line cards (LCs), which host their own NPUs (Network Processing Units) or ASICs (Application Specific Integrated Circuits) that are programmed by Supervisor to properly forward, filter and otherwise process user traffic. Supervisor Engines can also host switching matrix, that connects line cards together and allows for faster traffic transport between ports on different line cards, as well as can support traffic replication for multicast.
Cisco uses CEF (Cisco Express Forwarding) to create forwarding and routing tables, that in modular switches and routers is distributed using dCEF (distributed CEF). Line Cards that offer distributed forwarding & routing run their own copy of CEF tables thanks to dCEF.
