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.
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).
