3 Fibre channel F_Port Fibre channel fabric port (F_Port) is the switch port that connects the Fibre Channel (FC) fabric to a node. S4148U-ON switches support F_Port. Enable Fibre channel F_Port mode globally using the feature fc domain-ID domain-ID command in CONFIGURATION mode. Enable Fibre channel F_Port mode OS10(config)# feature fc domain-id 100 N_Port A node port (N_Port) is a port on a network node that acts as a host or storage device, and is used in FC point-to-point or FC switched fabric topologies. N_Port ID Virtualization (NPIV) allows multiple N_Port IDs to share a single physical N_Port. The NPIV Proxy Gateway (NPG) provides Fibre Channel over Ethernet (FCoE) to Fibre Channel (FC) bridging and vice versa. Enable NPG mode globally using the feature fc npg command in CONFIGURATION mode. Enable NPG mode OS10(config)# feature fc npg Fibre Channel over Ethernet Fibre Channel over Ethernet (FCoE) encapsulates Fibre channel frames over Ethernet networks. FCoE Initialization protocol (FIP) establishes Fibre channel connectivity with Ethernet ports. FIP snooping bridge (FSB) implements security characteristics to admit valid FCoE traffic in the Ethernet networks. FIP and FCoE provide FC emulation over Ethernet links. An Ethernet switch configured to operate in FSB mode snoops FIP packets on FCoE enabled VLANs and discovers the following information: • End nodes (ENodes) • Fibre channel forwarder (FCF) • Connections between ENodes and FCFs • Sessions between ENodes and FCFs Using the discovered information, the switch installs ACL entries that provide security and point-to-point link emulation.
