4 Fibre Channel OS10 switches with Fibre Channel (FC) ports operate in one of the following modes: Direct attach (F_Port), NPIV Proxy Gateway (NPG), or FIP Snooping Bridge (FSB). In the FSB mode, you cannot use the FC ports. F_Port Fibre Channel fabric port (F_Port) is the switch port that connects the 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. OS10(config)# feature fc domain-id 100 NPIV Proxy Gateway 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. Starting from OS 10.4.1, NPG supports FC to FC switching as well. The S4148U-ON supports both, CNA and HBA, in NPG mode. Enable NPG mode globally using the feature fc npg command in CONFIGURATION mode. To change the port mode from default N_Port, use the fc port-mode F command on FC interfaces. NOTE: In a switch configured in NPG or F-Port mode, OS10 does not support scale profile VLAN configuration.To use scale profile configuration in NPG or F-Port mode, enable CPU-based VLAN flooding on the vfabric VLAN using the mode L3 command. FIP snooping bridge FCoE encapsulates FC frames over Ethernet networks. FCoE Initialization protocol (FIP) establishes FC connectivity with Ethernet ports. FSB implements security characteristics to admit valid FCoE traffic in the Ethernet networks. FIP and FCoE provide FC emulation-overEthernet links. OS10 switches with Ethernet ports operate in FSB. OS10(config)# feature fip-snooping An Ethernet switch operating 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 NOTE: OS10 supports multiple ENodes in F_Port mode. Using the discovered information, the switch installs ACL entries that provide security and point-to-point link emulation. 198 Fibre Channel
