  • Page 13: Overview

    Native Fibre Channel implements a lossless service at the transport layer using a buffer-to-buffer credit system. Ethernet links on Cisco NX-OS switches provide two mechanisms to ensure lossless transport for FCoE traffic: link-level flow control and priority flow control.

  • Page 14: Fibre Channel Bridge

    Bridge also encapsulates FC frames from a Fibre Channel network and forwards them to the FCoE network. Cisco MDS 9500 switches support Fibre Channel Bridge functions. The Cisco Nexus 7000 series switches do not offer native Fibre Channel ports and do not support FC Note Bridge functions.

  • Page 15: Fcoe

    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.
