User and Enable Modes
In Cisco devices, there are two modes of operation: User mode and Enable mode.
User mode, also known as user EXEC mode, is the default mode when you log into the device. In user mode, you can view the device configuration and check the status of the device, but you cannot make any changes to the configuration.
To enter enable mode, also known as privileged EXEC mode, you need to provide a password. In enable mode, you can access all the configuration commands, including those that can modify the configuration of the device. The enable password can be set using the “enable password” or “enable secret” commands. The “enable secret” command stores the password in an encrypted format, making it more secure than the “enable password” command.
It is important to restrict access to the enable mode using a strong password to prevent unauthorized access to the device’s configuration. Additionally, it is recommended to use separate usernames and passwords for different users with varying levels of access. This can be achieved through the use of Role-Based Access Control (RBAC) or by configuring individual usernames with specific privilege levels.
