Fibre Channel
OS10 switches with Fibre Channel (FC) ports operate in one of the following modes: Direct attach (F_Port), NPIV Proxy
Gateway (NPG). In the FSB mode, you cannot use the FC ports.
E_Port
Expansion port (E_Port) in a switch is used to connect two fiber channel switches to form a multiswitch SAN fabric.
The default port mode in a multiswitch setup is F. You can create a multiswitch fabric by configuring the port mode as E on the
interface that connects two switches, which creates an interswitch link (ISL) consecutively. Enable the multiswitch fabric mode
using the feature fc [domain-id domain-id-val | npg | fip-snooping [with-cvl] | multi-switch]
command in CONFIGURATION mode.
OS10(config)# feature fc multi-switch
F_Port
Fibre Channel fabric port (F_Port) is the switch port that connects the FC fabric to a host. S4148U-ON, MX9116n, and MX7116n
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 conversely.
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.
MX9116n, and MX7116n 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 that is 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-over-Ethernet links. OS10 switches with Ethernet ports operate in FSB.
MX9116n and MX5108n switches operate in Full Switch and SmartFabric modes. When the switch is in SmartFabric mode, it is
recommended to use the untagged VLAN as 1 for FCoE-enabled interfaces.
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 (E-Nodes)
Fibre Channel Forwarder (FCF)
Connections between E-Nodes and FCFs
Sessions between E-Nodes and FCFs
