Before you access and configure your Cisco device, you should have a clear idea about CLI access modes. Each Cisco device supports several access modes. For CLI interaction, four modes are supported:
If you see a prompt with ‘>’ character at the end of the information, its indicate that you are in User EXEC Mode.
The default name used by the cisco for all their router is “Router” and the prompt look like “Router>” and switch’s are named “Switch” and prompt look like “Switch>”
If a username and password configured, you will be prompted for a credential. After successfully authenticate you can get access to Privilege EXEC mode and ‘>’ change to ‘#’. For router “Router#” and for Switch “Switch#”
In this mode, you have access to advanced management and troubleshooting commands like extended ping and trace abilities, managing configuration files and IOS images, and detailed troubleshooting.
- User EXEC Mode: your initial access to the CLI is through this mode. It has only limited number of commands you can execute. You might be prompted for a credential to access this mode. This mode is used for basic troubleshooting of network issues.
If you see a prompt with ‘>’ character at the end of the information, its indicate that you are in User EXEC Mode.
The default name used by the cisco for all their router is “Router” and the prompt look like “Router>” and switch’s are named “Switch” and prompt look like “Switch>”
- Privilege EXEC: this level provides high-level management access to the IOS, including all commands available at User EXEC mode.
If a username and password configured, you will be prompted for a credential. After successfully authenticate you can get access to Privilege EXEC mode and ‘>’ change to ‘#’. For router “Router#” and for Switch “Switch#”
In this mode, you have access to advanced management and troubleshooting commands like extended ping and trace abilities, managing configuration files and IOS images, and detailed troubleshooting.
- Configuration: This mode allows you to configure and made changes to the Cisco device. This mode you can see ‘Router#’/”Switch#” changes to “Router(config)#”/ “Switch(config)#”.
- ROMMON: Loads a bootstrap program that allows for low-level diagnostic testing of the IOS device, performing the password recovery procedure, and performing an emergency upgrade etc.
