Configuring FCoE
Fibre Channel over Ethernet (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.
This chapter describes how to configure FCoE and includes the following sections:
• Information About FCoE, page 1-1
• Configuring FCoE, page 1-4
• Configuring LLDP, page 1-6
• Verifying FCoE Configuration, page 1-8
Information About FCoE
In Cisco Nexus 5000 Series switches, FCoE is supported on all 10-Gigabit Ethernet interfaces.
To use FCoE, the switch must be directly connected to the server and the server port must terminate the
Ethernet with a converged network adapter.
This section includes the following topics:
• Licensing Requirements, page 1-1
• Converged Network Adapters, page 1-2
• DCBX Capabilities, page 1-2
• DCE Bridging Capability Exchange Protocol, page 1-3
• DCBX Feature Negotiation, page 1-3
• Ethernet Frame Formats, page 1-4
Licensing Requirements
On Cisco Nexus 5000 Series switches, FCoE capability is included in the Storage Protocol Services
License.
Before using FCoE capabilities, ensure that:
• The correct license is installed (N5010SS or N5020SS).
• FCoE is activated by entering the feature fcoe command in configuration mode.
