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 congured to operate in NPG or F-Port mode, OS10 does not support scale prole VLAN conguration. If you

want to use scale prole conguration in NPG or F-Port mode, enable CPU based VLAN ooding 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 trac 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
