Cisco CSR 1000v Series User Manual

by default. For example, IP routing is enabled by default. To disable IP routing, use the no ip routing command;
to re-enable IP routing, use the ip routing command. The Cisco IOS XE software command reference
publications provide the complete syntax for the configuration commands and describe what the no form of
a command does.
Many CLI commands also have a default form. By issuing the command default command-name , you can
configure the command to its default setting. The Cisco IOS XE software command reference publications
describe the function of the default form of the command when the default form performs a different function
than the plain and no forms of the command. To see what default commands are available on your system,
enter default ? in the appropriate command mode.
Use the copy running-config startup-config command to save your configuration changes to the startup
configuration so that the changes will not be lost if the software reloads or a power outage occurs. For example:
Router# copy running-config startup-config
Building configuration...
It might take a minute or two to save the configuration. After the configuration has been saved, the following
output appears:
[OK]
Router#
This task saves the configuration to NVRAM.
On the Cisco CSR 1000v, the startup configuration file is stored in the NVRAM partition. As a matter of
routine maintenance on any Cisco router, users should backup the startup configuration file by copying the
startup configuration file from NVRAM onto one of the router’s other file systems and, additionally, onto a
network server. Backing up the startup configuration file provides an easy method of recovering the startup
configuration file in the event the startup configuration file in NVRAM becomes unusable for any reason.
The copy command can be used to backup startup configuration files. The following examples show the
startup configuration file in NVRAM being backed up:
Example 1: Copying a Startup Configuration File to Bootflash
Router# dir bootflash:
