Configurations will act in device memory.Cisco IOS User Interface FunctionsCisco IOS User Interface FunctionsA CLI is used to enter commands. Operations vary on different internetworking devices. Users type or paste entries in the console command modes. Enter key instructs device to parse and execute the command. Two primary EXEC modes are user mode and privileged mode. Command modes have distinctive prompts.Cisco IOS Software EXEC ModeCisco IOS Software EXEC ModeThere are two main EXEC modes for entering commands.Cisco IOS Software EXEC Mode (Cont.)Cisco IOS Software EXEC Mode (Cont.)SummarySummaryThe Cisco IOS software platform is implemented on all Cisco hardware platforms. You will use Cisco IOS software to communicate the configuration details that implement the learning objectives of this course. You can configure a switch or router from sources that are external to the device. Cisco IOS software uses a CLI as its traditional console environment. While Cisco IOS software is a core technology, Cisco IOS software operation details vary on different internetworking devices.
