Information About FCoE

FCoE provides a method of transporting Fibre Channel traffic over a physical Ethernet connection. FCoE
requires the underlying Ethernet to be full duplex and to provide lossless behavior for Fibre Channel traffic.
Lossless behavior on Ethernet is provided by using a priority flow control (PFC) mechanism that prevents
Note
packet loss during congestion conditions.
The Cisco NX-OS software supports T11-compliant FCoE on all 10-Gigabit Ethernet interfaces.

FCoE and FIP

FCoE Initiation Protocol

The FCoE Initialization Protocol (FIP) allows the switch to discover and initialize FCoE-capable entities that
are connected to an Ethernet LAN. Cisco NX-OS switches support the Converged Enhanced Ethernet Data
Center Bridging Exchange (CEE-DCBX) protocol for T11-compliant Generation 2 CNAs.
The following switches do not support Pre-FIP on Generation 1 CNAs:
OL-25809-02
