How do you access and navigate cisco ios configurating network devices?

To access Cisco iOS for configuring network devices, you typically connect via a console cable to the device's console port or remotely through SSH/Telnet if the device is already configured for network access. Once connected, you enter privileged EXEC mode by typing enable, and from there, you can enter global configuration mode using the configure terminal command. Navigation is done using command-line interface commands, and you can utilize context-sensitive help by pressing the question mark ? to see available commands or options. To save configurations, use the write memory or copy running-config startup-config commands.
