In a Cisco IOS environment, defining an interface range is essential for configuring multiple interfaces simultaneously and efficiently. The correct syntax to define an interface range is "interface range type member/module/number".

This format indicates the type of interface you are configuring (such as Ethernet, FastEthernet, or Serial), followed by the specific module and interface number. For example, if you wanted to configure a range of FastEthernet interfaces on Module 2 starting from interface 1 through 24, you would use a command that resembles the correct syntax. This approach is particularly useful in environments where configurations must be applied uniformly across several interfaces, like when enabling an interface, setting a description, or creating VLAN assignments.

Other options deviate from this structure, which is crucial for proper configuration. For instance, options that suggest missing or incorrect placements of keywords (like using "module" or "number" in the wrong order) do not conform to the accepted syntax and wouldn't be recognized by the IOS command line interface. Mastery of this syntax not only aids in effective configuration but also minimizes errors when managing multiple interfaces within a Cisco network.
