Chapter 3 Operation The 9E312-12 module is a thirteen port device; twelve front panel ports, each represents a separate Ethernet collision domain and one port connected to INB1. As shown in Figure 3-1, Ethernet Network Interface Blocks (ENIBs) convert data packets received from any front panel port into a canonical frame format before forwarding to the Fast Packet Switch (FPS), while the Internal Network Bus Network Interface Block (INB NIB) converts data packets received from the INB

Operation ENIB The Ethernet Network Interface Block (ENIB) converts Ethernet data packets received through front panel ports into a common canonical format that allows the Fast Packet Switching Engine to determine the proper destination port. The ENIB also converts data packets from the common canonical format back to Ethernet data packets for transmission out front panel ports. Fast Packet Switch The Fast Packet Switch (FPS) is a hardware based switch design that is the key build
