Cisco Router Modes | Basic CLI Commands

The CLI command prompt is typically used when configuring Cisco network devices. Also, it has a mode and a work partition for the use of a command.

Cisco Router Modes | Basic CLI Commands

IOS Configuration Modes

The Cisco Router modes are basically 3 parts. These; user management mode, privileged management mode, and general configuration mode.

When configuring a Router, you must use the required commands in the corresponding mode.

For example, the ip address command is used in global configuration mode to assign IP to an interface.

After activating a corresponding setting in the CLI, you can switch to the previous mode.

1. User Executive Mode

The first mode in the CLI command interface is User Management Mode.

In this mode, you can get information about your device. However, you cannot perform any operation on the Router.

The Enable command is used to switch from this mode to the next mode.

User Executive Mode

2. Privileged Execute Mode

In this mode, you can usually save the running router configurations, browse the running configuration, review the Router IOS version.

In particular, a password is set in this section. Because a user accessing this section can fully configure and manage the Router.

If you do not set a password in this mode, a user who reaches your device can damage your device with the R1# erase command!

As in the image below, you can use the “?” character to display all the commands you can use in this mode interface.

For example; With “R1# copy?“, all commands belonging to the copy command will be listed.

Privileged Execute Mode

3 . Global Configuration Mode

You can use the configure terminal command to switch to global configuration mode after Privileged Executive Mode.

The mode you use most frequently is the Config mode. Here you can make all settings on the Router.

For example, you can turn on the FastEthernet interface and assign an IP address with the R1(config)# interface FastEthernet 0/0 command.

Global Configuration Mode

Switching Between Modes

You can switch between the modes. For example, you can use the disable command to change from an up mode to a down mode.

In addition, you can use End and Ctrl+Z to switch from config mode to a sub-mode.
