Chapter 1 Product Overview
Nexus 5000 Series Switch Software
FCoE and Fibre Channel Switching
Nexus 5000 Series switches support data center I/O consolidation (IOC) by providing FCoE interfaces
(to the servers) and native Fibre Channel interfaces (to the SAN).
FCoE and Fibre Channel switching includes the following features:
• Cisco fabric services
• N-port virtualization
• VSANs and VSAN trunking
• Zoning
• Distributed device alias service
• SAN port channels
Licensing
Cisco Nexus 5000 Series switches are shipped with the licenses installed. The switch provides commands to
manage the licenses and install additional licenses.
QoS
The Nexus 5000 Series switch provides quality of service (QoS) capabilities such as traffic prioritization
and bandwidth allocation on egress interfaces.
The default QoS configuration on the switch provides lossless service for Fibre Channel and FCoE
traffic. QoS can be configured to provide additional classes of service for Ethernet traffic.
Serviceability
The Nexus 5000 Series switch serviceability functions provide data for network planning and help to
improve problem resolution time.

Switched Port Analyzer
The switched port analyzer (SPAN) feature allows an administrator to analyze all traffic between ports
by nonintrusively directing the SPAN session traffic to a SPAN destination port that has an external
analyzer attached to it.
