Understanding the Cisco IOS File System
To configure a static IP route, perform the following steps, beginning in global configuration mode:
Example
The following example shows how to configure an IP address on the main Ethernet port, then save the
configuration.
Switch(config)# interface ethernet 0
Switch(config-if)# ip address 172.20.52.11 255.255.255.224
Switch(config-if)# end
Switch# copy system:running-config nvram:startup-config
Understanding the Cisco IOS File System
This release of the ATM switch router system software uses the Cisco IFS (IOS File System). With IFS,
you now access files on a storage device by specifying a filename and the file system containing the file.
The following old command, for example, accesses the running-config and startup-config files:
Switch# copy running-config startup-config
With IFS, you additionally specify the system containing the files using the syntax filesystem:filename.
For example:
Switch# copy system:running-config nvram:startup-config
The syntax filesystem:filename is called the file URL. In addition, remote file systems (such as TFTP,
FTP, and rcp) allow you to specify additional options in the file URL, such as username, password,
remote host, and so on. This way, you can enter all the required information at once without having to
respond to prompts.
With IFS, some show commands have been replaced with more commands. For example:
Switch# show running-config
has been replaced with the following command:
Switch# more system:running-config
For complete information on using file URLs and the new IFS commands and syntax, refer to the
Configuration Fundamentals Configuration Guide and the Configuration Fundamentals Command
Reference publications.
