Information About Ethernet Interfaces
The Ethernet ports can operate as standard Ethernet interfaces connected to servers or to a LAN.
The Ethernet interfaces also support Fibre Channel over Ethernet (FCoE). FCoE allows the physical Ethernet
link to carry both Ethernet and Fibre Channel traffic.
On a Cisco Nexus 5000 Series switch, the Ethernet interfaces are enabled by default.
About the Interface Command
You can enable the various capabilities of the Ethernet interfaces on a per-interface basis using the interface
command. When you enter the interface command, you specify the following information:
• Interface type—All physical Ethernet interfaces use the ethernet keyword.
• Slot number
◦ Slot 1 includes all the fixed ports.
◦ Slot 2 includes the ports on the upper expansion module (if populated).
◦ Slot 3 includes the ports on the lower expansion module (if populated).
• Port number
◦ Port number within the group.
The interface numbering convention is extended to support use with a Cisco Nexus 2000 Series Fabric Extender
as follows:
