Product Overview
The Cisco Nexus 5000 Series is a family of top-of-rack switches for the data center. The Cisco Nexus
5000 Series offers high-speed Ethernet switching and supports Fibre Channel over Ethernet (FCoE) to
provide data center I/O consolidation (IOC).
The Nexus 5010 switch provides 20 fixed Ethernet ports in a 1 RU switch and the Nexus 5020 switch
provides 40 fixed Ethernet ports in a 2 RU switch. Optional expansion modules provide native Fibre
Channel ports and additional Ethernet ports.

New Technologies in the Cisco Nexus 5000 Series
Cisco Nexus 5000 Series switches introduce several new technologies, which are described in the
following sections:
• Fibre Channel over Ethernet, page 1-1
• I/O Consolidation, page 1-2
• Virtual Interfaces, page 1-3
Fibre Channel over Ethernet
Fibre Channel over Ethernet (FCoE) provides a method of encapsulating Fibre Channel traffic over a
physical Ethernet link. FCoE frames use a unique Ethertype so that FCoE traffic and standard Ethernet
traffic can be carried on the same link.
Fibre Channel traffic requires a lossless transport layer. Native Fibre Channel implements lossless
service using a buffer-to-buffer credit system. For FCoE traffic, the Ethernet link must provide lossless
service.
Ethernet links on Cisco Nexus 5000 Series switches provide two mechanisms to ensure lossless transport
for FCoE traffic: link-level flow control and priority flow control.
