Saving Configuration Changes

Any time you make changes to the router configuration, you must save the changes to memory because if you do not they will be lost if there is a system reload or power outage. There are two types of configuration files: the running (current operating) configuration and the startup configuration. The running configuration is stored in RAM; the startup configuration is stored in NVRAM.

To display the current running configuration, enter the show running-configcommand. Enter the copy running-configstartup-configcommand to save the current running configuration to the startup configuration file in NVRAM.

Router> enable

Router# copy running-config startup-config

To display the startup configuration, enter the show startup-configcommand. Enter the copy startup-configrunning-configcommand to write the startup configuration to the running configuration:

Router> enable

Router# copy startup-config running-config

	To erase both configuration files (and start over), enter the write erase and
	reload commands:
	Router> enable
	Router# write erase
	Router# reload
C A U T I O N	This command sequence will erase the entire router configuration in RAM and
	NVRAM and reload the router.
	Configuring ISDN
	This section describes a recommended ISDN configuration for one or two B
	channels. In the examples that follow, the BRI port is configured for IP routing,
	Challenge Handshake Authentication Protocol (CHAP), and Point-to-Point
	Protocol (PPP) encapsulation.
	For your reference, an example configuration follows in the next section,
	“Example ISDN Connection”. You may want to refer to “Example ISDN
	Configuration” during this procedure.
