Important! You MUST save any changes you make in running configuration to the startup configuration file if you want those changes to remain after a system reload. From the privileged level, configurations can be saved using the write command, or by using the copy
From the privileged level, you can access global configuration mode, as described in the following section.
3.3 Global Configuration Mode
Global configuration commands apply to features that affect the system as a whole, rather than just one protocol or interface. Commands to enable a particular routing function are also global configuration commands. To enter the global configuration mode, use the configure terminal command.
The following example shows how to access and exit global configuration mode and list global configuration commands.
Command | Purpose |
|
|
Router# configure terminal | From privileged EXEC mode, enters global |
| configuration mode. |
Router(config)# ? | Lists the global configuration commands. |
|
|
To exit global configuration command mode and return to privileged EXEC mode, use one of the following commands:
Command
exit end Ctrl-Z
Purpose
Exits global configuration mode and returns to privileged EXEC mode.
To list the commands available in global configuration mode, enter a question mark (?) at the prompt, as shown in the following example. Enter a question mark (?) after a command to see all the options for that command.
