ENIB

The Ethernet Network Interface Block (ENIB) converts Ethernet data packets received through front panel ports into a common canonical format that allows the SmartSwitch ASIC 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.
