With Aruba CX 6300. how do you configure ip address 10 10 10 1 for the interface in default state for interface 1/1/1?

On an Aruba CX 6300 switch, physical interfaces are Layer 2 (switching) ports by default. To assign an IP address, the interface must first be converted into a Layer 3 (routed) port. The correct command in the ArubaOS-CX command-line interface to enable Layer 3 functionality on a physical interface is routing. After the port is configured as a routed interface, the ip address command can be used to assign the IP address and subnet mask. This makes option D the only correct procedure.

A. The command switching is not a valid ArubaOS-CX command for configuring an interface's mode.
B. The command no switching is not a valid command in ArubaOS-CX to enable routing. The correct command is routing.
C. An IP address cannot be assigned directly to an interface that is in its default Layer 2 mode. The command would be rejected by the switch.

Chapter 3: "Routed Interfaces"

Page 23. The guide explicitly shows the command sequence for configuring a routed interface: interface

no shutdown

routing

and then ip address /. This confirms routing is the correct command.

"Routed interfaces". This section states: "To configure a physical interface as a routed interface

it must be enabled for layer 3 routing using the routing command." This directly contradicts the syntax used in options A and B and confirms that an interface must be changed from its default state before an IP address can be applied.
