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.
S4148U-ON switches support 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 congured in NPG or F-Port mode, OS10 does not support scale prole VLAN conguration.To use scale
prole conguration in NPG or F-Port mode, enable CPU-based VLAN ooding 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 trac in the Ethernet networks. FIP and FCoE provide FC emulation-over-
Ethernet links. OS10 switches with Ethernet ports operate in FSB.
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.
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.
