15 FCoE Transit The Fibre Channel over Ethernet (FCoE) Transit feature is supported on Ethernet interfaces. When you enable the switch for FCoE transit, the switch functions as a FIP snooping bridge. NOTE: FIP snooping is not supported on Fibre Channel interfaces. Topics: • Fibre Channel over Ethernet • Ensure Robustness in a Converged Ethernet Network • FIP Snooping on Ethernet Bridges • FIP Snooping in a Switch Stack • Using FIP Snooping • Configuring FIP Snooping • Displaying FIP Snooping Information • FCoE Transit Configuration Example Fibre Channel over Ethernet FCoE provides a converged Ethernet network that allows the combination of storage-area network (SAN) and LAN traffic on a Layer 2 link by encapsulating Fibre Channel data into Ethernet frames. FCoE works with the Ethernet enhancements provided in data center bridging (DCB) to support lossless (nodrop) SAN and LAN traffic. In addition, DCB provides flexible bandwidth sharing for different traffic types, such as LAN and SAN, according to 802.1p priority classes of service. DCBx should be enabled on the system before the FIP snooping feature is enabled. For more information, refer to the Data Center Bridging (DCB) chapter. Ensure Robustness in a Converged Ethernet Network Fibre Channel networks used for SAN traffic employ switches that operate as trusted devices. To communicate with other end devices attached to the Fibre Channel network, end devices log into the switch to which they are attached. Because Fibre Channel links are point-to-point, a Fibre Channel switch controls all storage traffic that an end device sends and receives over the network. As a result, the switch can enforce zoning configurations, ensure that end devices use their assigned addresses, and secure the network from unauthorized access and denialof-service (DoS) attacks.
