Physical ports
Physical ports are administratively down by default. Each interface has a reserved MAC hardware address derived from the system MAC
address. Use standard Linux commands to congure physical interface parameters.

See Application examples in the OpenSwitch OPX Developers Guide for examples of how to program physical port conguration using the
CPS API.
Fan-out interfaces
Using a breakout cable, you can split a 40GbE physical port into four (quad) 10GbE SFP+ ports (if supported by the NPU). Each 4x10G
port is represented by a Linux interface with a fan-out eld in the interface name that identies the 4x10G port.
Use the opx-config-fanout script to congure fan-out interfaces. This script allows you to fan-out a 40GbE port or disable the
fanned-out 4x10G conguration and return the physical port to 40G operation.
opx-config-fanout portID [true | false]
• true enables 4x10G fan-out on a 40GbE port
• false disables 4x10G fan-out on a 40GbE port
