The Cisco ISO is the "Operating System" of the Cisco device. The user can configure the device by accessing and changing the configuration in the ISO.

NVRAM
To assign an IP address to a device connected via a serial port, you typically use a terminal emulation program (like PuTTY or Tera Term) to access the device's command-line interface. Once connected, you can enter configuration commands specific to the device's operating system, such as ip address [IP_ADDRESS] [SUBNET_MASK] in Cisco IOS. Be sure to save the configuration after making changes. The exact commands may vary depending on the device and its firmware.
In the global configuration mode, type enable secret See below example:Router>enableRouter#configure terminalEnter configuration commands, one per line. End with CNTL/Z.Router(config)#enable secret passwordRouter(config)#exitRouter#
All passwords in the configuration are not shown in clear text when viewing the configuration.
The Cisco IOS commands allow the user to enter partial Cisco IOS commands. If you start to type in a command it can recognize it and finish the command for you.
This command will allow you to copy a configuration from a TFTP server to the running configuration of a Cisco device. When you issue the command you will be prompted for further details about the TFTP server. The new configuration will replace the active one (or running configuration) and make any necessary changes.
Show CDP Interface
To empty the startup configuration on a Cisco device, you can use the command erase startup-config in privileged EXEC mode. To remove the running configuration, you can use the command write erase followed by reload to restart the device, which will clear the running configuration and load the default settings. Remember to save any necessary configurations before performing these actions, as they will result in data loss.
wr or copy running-config startup config
To enter IOS 5 codes on a Cisco device, you typically access the device's command-line interface (CLI) through a console connection or SSH. Once logged in, you can use the "configure terminal" command to enter global configuration mode. From there, you can input the necessary IOS commands to configure the device as required. Ensure you have the proper privileges to make changes.
