Overview of the CLI Command Modes for Cisco IOS XE
The Cisco IOS XE command-line interface is divided into many command modes to assist in the configuration of Cisco equipment. Each command mode has a unique set of commands available for the configuration, upkeep, and monitoring of router and network activities. Your current mode will determine which instructions are available to you. You can get a list of the commands available for each command mode by palo alto firewall image download for gns3.
You can switch between different command modes by using specified commands. The modes are often accessed in the following order by a user: user EXEC mode, privileged EXEC mode, global configuration mode, particular configuration modes, configuration submodels, and configuration submodes.
One of the two access levels of the EXEC mode, user EXEC mode, is often where you start a session on a router. Just a small number of EXEC commands are accessible in user EXEC mode due to security concerns. This level of access should only be used for operations that don’t involve changing the router’s settings, such as checking its status.
