There are three main modes when working with the Cisco IOS: user EXEC mode, privileged EXEC mode, and global configuration mode. User EXEC mode is the default mode when you connect to a Cisco device. In this mode, you can view device information and run a few limited commands.
Privileged EXEC mode gives you access to all commands on the device. To enter this mode, you must enter the enable command. Global configuration mode is where you can change the device’s settings.
To enter this mode, you must enter the configure terminal command.
There are four main command modes on a Cisco IOS device: user EXEC mode, privileged EXEC mode, global configuration mode, and interface configuration mode. User EXEC mode is the initial access point for users when they first connect to a Cisco device. This mode gives them limited access to commands that allow them to view the status of the system but not make any changes.
Privileged EXEC mode provides full access to all commands on the system, including those that can change configuration settings. Global configuration mode allows users to modify the general system settings for the router or switch. Interface configuration mode allows users to configure individual interfaces on a device.

What are the Three Ios Modes?
There are three different modes that can be used with the iPhone: sleep, standby, and power off.
Sleep mode is when the phone is inactive for a period of time. The screen will turn off and the phone will go into a low-power state.
In this mode, you can still receive calls and texts, but most other functions will be disabled.
Standby mode is similar to sleep mode, but in this case, all functions are disabled except for receiving calls and texts. This mode is typically used when the battery is running low and you want to conserve as much power as possible.
Power off is just what it sounds like—the phone is turned off completely and uses no power whatsoever. To turn the phone back on, you’ll need to press and hold the Sleep/Wake button until the Apple logo appears.
What are the 4 Types of Mode in a Router?
A router is a networking device that forwards data packets between computer networks. Routers operate at layer 3 of the OSI model, the network layer. This makes them responsible for routing IP packets between different subnets and network devices.
Routers use specialised software, called firmware, to make decisions about where to route each packet.
There are four main types of mode in a router: static mode, dynamic mode, default mode and transparent mode.
Static Mode: In static mode, the router uses a pre-configured list of routes to determine where to send data packets.
Static routes are typically used in small networks or when there is only one path between two networks. Dynamic Mode: In dynamic mode, the router uses protocols such as RIP or OSPF to automatically learn about new routes and update its routing table accordingly. Dynamic routing is typically used in larger networks where there are multiple paths between two networks.
Default Mode: In default mode, the router will send data packets destined for unknown addresses to a predefined “default gateway” – usually another router on the network. Transparent Mode: In transparent mode, also known as “bridge mode”, the router does not perform any routing functions and simply forwards data packets between ports without making any changes to them. Transparent mode is typically used when two routers need to be connected together but you do not want either of them to perform any routing functions (i.e., they are both just acting as simple switches).
What are the Three 3 Cli Modes?
There are three CLI modes in networking: user mode, privileged mode, and global configuration mode. User mode is the default mode when you first connect to a router or switch. In this mode, you can view information but not make any changes.
Privileged mode gives you access to all commands, including those that change the configuration of the device. Global configuration mode allows you to change the device’s settings; for example, setting passwords or IP addresses.
What are Command Modes?
Command modes are the various ways in which a user can enter commands into a computer. The most common mode is the graphical user interface (GUI), which uses a pointing device such as a mouse to click on icons or menus to issue commands. Other modes include the command line interface (CLI), where users type commands, and voice recognition, where users speak commands.
Cisco User Exec Mode Commands
Cisco User Exec Mode Commands
The Cisco IOS user exec mode commands provide a limited set of commands that allow a user to perform basic tasks and troubleshoot problems. The user exec mode is the first level of access for all users and does not provide full access to all IOS commands.
In this mode, a user can view system information, change terminal settings, and run a limited number of show commands. To enter user exec mode from any other mode, use the command line interface (CLI) command line “>” followed by an Enter keystroke.
The following table lists the most common Cisco IOS user exec mode commands:
Table 1.
Conclusion
Cisco IOS has three main command modes: user EXEC mode, privileged EXEC mode, and global configuration mode. User EXEC mode is the most restricted of the three modes. In this mode, only a limited set of show commands can be issued.
Privileged EXEC mode provides access to all commands that can be used to view and change the router’s configuration. Global configuration mode allows users to change the router’s configuration.
