3 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. OS10 switches with Ethernet ports operate in FIP Snooping Bridge (FSB). 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. Enable Fibre Channel F_Port 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. Enable NPG mode globally using the feature fc npg command in CONFIGURATION mode. You can use the fc port-mode F command on FC interfaces to change the port mode from default N_Port. Enable NPG mode OS10(config)# feature fc npg NOTE: In a switch configured to operate in NPG or F-Port mode, OS10 does not support scale profile VLAN configuration. If you want to use scale profile configuration in NPG or F-Port mode, enable CPU based VLAN flooding on vfabric VLAN using the mode L3 command. FIP snooping bridge Fibre Channel over Ethernet (FCoE) encapsulates FC frames over Ethernet networks. FCoE Initialization protocol (FIP) establishes FC 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. NOTE: OS10 switches do not support multi-hop FIP snooping bridge (multi-hop FSB) capability; links to other FIP snooping bridges on a FIP snooping-enabled device (bridge-to-bridge links) are not supported. Enable FIP snooping mode OS10(config)# feature fip-snooping Fibre Channel 125
