Explanation

Cisco IOS Interface Configuration Command Structure

The command being built is the interface command, which follows this syntax:

interface GigabitEthernet 0/1

Breaking that into its structural components:

The Correct Arrangement

[component to configure] [interface type] [slot]/[port]
       interface           GigabitEthernet    0  /  1

Item-by-Item Explanation

1. component to configure → Position 1 (the command keyword) This is the word interface itself - the IOS command that enters interface configuration mode. It always comes first because it tells the CLI what you are about to configure. Without it, the router has no context for what follows.

2. interface type → Position 2 (after the command keyword) This is the technology type: GigabitEthernet, FastEthernet, Serial, Loopback, etc. It immediately follows interface because the router needs to know the media type before it can resolve the physical location.

3. slot → Position 3 (first number, before the slash) The slot is the physical module bay in the chassis where the line card is installed (e.g., 0 in 0/1). On fixed-configuration switches it's often 0, but on modular routers it identifies which card. The slot comes before the port because it narrows down location from chassis → card → port.

4. port → Position 4 (second number, after the slash) The port is the specific physical interface on that line card. It always comes last because it's the most granular identifier.
