FIP Snooping
In traditional Fibre Channel Storage-Area Network (SAN), nodes (ENodes) that want to communicate through the fabric must log in to the fabric first. Because Fibre Channel links are point-to-point links, the Fibre Channel switch has complete control of the traffic received from the ENodes into the fabric. This prevents erroneous or malicious behavior resulting from spoofing Fibre Channel addressing. With FCoE, physical point-to-point relationships between the ENodes and FCoE Fibre Channel Forwarders is replaced by the FIP protocol, which enables the ENodes and the FCoE Fibre Channel Forwarders to be separated by several DCB-enabled Ethernet segments, while building logical point-to-point links between the two. It is still possible ...
