Reference Guide

An Ethernet switch congured to operate 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.
Terminology
ENode
End Node or FCoE node
FC Fibre Channel
FC ID A 3-byte address used by FC to identify the end points
FC Map A 3-byte prex congured per VLAN, used to frame FCoE MAC address
FCF Fibre Channel Forwarder
FCoE Fibre Channel over Ethernet
FCoE MAC Unique MAC address used to identify an FCoE session. This is a combination of FC ID and FC Map.
FIP FCoE Initialization Protocol
NPG NPIV Proxy Gateway
NPIV N_Port ID Virtualization
Virtual fabric
Virtual fabrics (vfabric) divide a physical fabric into logical fabrics.
Manage each vfabric independently. The fabric ID identies each vfabric.
You can congure only one vfabric in the F_Port mode and multiple vfabrics in the NPG mode.
The F_Port and NPG modes are mutually exclusive.
If you have already congured a vfabric in F_Port mode, while conguring vfabrics in NPG mode, disable the F_Port mode. The existing
vfabric is removed when you disable F_Port mode and you need to congure new vfabrics in NPG mode. If you are moving from NPG
mode to F_Port mode, then disable the NPG mode and create new vfabric in F_Port mode.
