The supervisor engine is a module that is installed in one of the card slots in the switch/router(more specifically the 7600). The supervisor engine provides switching and local and remote management for the switch/router.
The supervisor engine contains the following integrated daughter cards that perform forwarding and routing and provide the protocols supported on the router:
Multilayer Switch Feature Card (MSFC) is the control plane and does the following:
.Performs routing for the chassis. The MSFC contains the route processor (RP) and switch processor (SP) for the router.
.Runs Layer 2 and Layer 3 protocols, such as the Spanning Tree Protocol (STP) and others.
Policy Feature Card (PFC) is the forwarding plane and does the following:
.Performs Layer 2 and Layer 3 forwarding.
.Enforces access control list (ACL) functions.
.Performs policing and marking for QoS traffic.
.Collects Netflow statistics.
