  • System Management
  • Layer 2 Switching
  • SAN Switching
  • Fibre Channel over Ethernet
  • Security
  • Quality of Service

The information in these new guides previously existed in the Cisco Nexus 5000 Series NX-OS Configuration Guide which remains available on Cisco.com and should be used for all software releases prior to Cisco Nexus 5000 NX-OS Software Rel 4.1(3). Each new configuration guide addresses the features that are introduced in or are available in a particular release. Select and view the configuration guide that pertains to the software installed in your switch.

The information in the new Cisco Nexus 5000 Series NX-OS Layer 2 Switching Configuration Guide previously existed in Part 2: LAN Switching of the Cisco Nexus 5000 Series CLI Configuration Guide.
