SR OS Data Plane Security

Which Nokia 7750 SR component is responsible for performing the longest-prefix-match lookup on packets received through the physical interfaces?

  • A Control Processing Module (CMP)
  • B Media Dependent Adapter (MDA)
  • C Switch Fabric (SF)
  • D Input/Output Module (IOM)
Explanation

The Input/Output Module (IOM) is the ingress forwarding component: it holds forwarding-plane information and performs the packet lookup for traffic received on an ingress network interface. Media Dependent Adapters provide physical interface connectivity, while the switch fabric transports traffic and the control module provides control-plane processing.
