This step is required only if you want to override the default remote username or password see Steps 2 and 3. Using FTP, copies the configuration file from a network server to running memory or the startup configuration.

The following example copies a host configuration file named host1-confg from the netadmin1 directory on the remote server with an IP address of To maintain a configuration file that exceeds size of NVRAM, perform the tasks described in the following sections:. When you have finished changing the running-configuration, saves the new configuration.

To store the startup configuration in Flash memory, complete the tasks in this section:. Copies the current startup configuration to the new location to create the configuration file.

If you try to load a configuration that is more than three times larger than the NVRAM size, the following error message is displayed:. To use a network server to store large configurations, complete the tasks in this section:. Specifies that the startup configuration file be loaded from the network server at startup. To control the Parser Cache feature, perform the tasks described in the following sections.

All of these tasks are optional:. To clear the information stored by the Parser Cache feature, complete the task in this section:. The Parser Cache feature is enabled by default.

To disable the Parser Cache feature, complete the task in this section:. To reenable the Parser Cache feature after disabling it, complete the task in this section:. The show parser statistics command displays two sets of data, as follows:.

To copy a configuration file from Flash memory directly to your startup configuration in NVRAM or your running configuration, enter one of the commands in Step The following example copies the file named ios-upgrade-1 from partition 4 of the Flash memory PC Card in slot 0 to the router startup configurations:.

On platforms with multiple Flash memory file systems, you can copy files from one Flash memory file system, such as internal Flash memory or a Flash memory card in a PCMCIA slot, to another Flash memory file system.

Copying files to different Flash memory file systems lets you create backup copies of working configurations and duplicate configurations for other routers. To copy a configuration file between Flash memory file systems, use the following commands in EXEC mode:. For example, the copy slot1: slot1: command is invalid.

The following example copies the file named running-config from partition 1 of internal Flash memory to partition 1 of slot 1 on a Cisco series router. In this example, the source partition is not specified, so the router prompts for the partition number.

To copy a configuration file from an FTP server to a Flash memory device, complete the task in this section:. Optional Enters global configuration mode. This step is required only if you override the default remote username or password see Steps 3 and 4. Optional Exits configuration mode. This step is required only if you override the default remote username see Steps 3 and 4. Copies the configuration file from a network server to the Flash memory device using FTP.

To copy a configuration file from an rcp server to a Flash memory device, complete the tasks in this section:. Copies the configuration file from a network server to the Flash memory device using rcp.

Reply to any router prompts for additional information or confirmation. The prompting will depending on how much information you provide in the copy command and the current setting of the file prompt command.

To copy a configuration file from a TFTP server to a Flash memory device, complete the task in this section:. Router copy tftp:router-config slot0:new-config. The copied file is renamed new-config. To reexecute the commands located in the startup configuration file, complete the task in this section:. Reexecutes the configuration commands located in the startup configuration file.

You can clear the configuration information from the startup configuration. If you reboot the router with no startup configuration, the router will enter the Setup command facility so that you can configure the router from scratch.

To clear the contents of your startup configuration, complete the task in this section:. The startup configuration file cannot be restored once it has been deleted. That is, the router marks the file as "deleted," rather than erasing it. This feature allows you to recover a deleted file. To delete a specified configuration on a specific Flash device, complete the task in this section:.

Note On Class A and B Flash file systems, when you delete a specific file in Flash memory, the system marks the file as deleted, allowing you to later recover a deleted file using the undelete EXEC command. Erased files cannot be recovered. To permanently erase the configuration file, use the squeeze EXEC command. On Class C Flash file systems, you cannot recover a file that has been deleted.

Copies the configuration file to the Flash file system from which the router will load the file upon restart. This configuration is then used as the startup configuration when the system is restarted.

After you specify a location for the startup configuration file, the nvram:startup-config command is aliased to the new location of the startup configuration file. The more nvram:startup-config EXEC command will display the startup configuration, regardless of its location. A distilled version is one that does not contain access list information. If NVRAM contains a complete configuration file, the router prompts you to confirm your overwrite of the complete version with the distilled version.

Eventually, Flash memory will be full, because the old configuration files still take up memory. Use the squeeze EXEC command to permanently delete the old configuration files and reclaim the space. To configure the Cisco IOS software to download a network configuration file from a server at startup, complete the tasks in this section:. If you omit the address, the router uses the broadcast address.

The software tries them in order entered until it loads one. This procedure can be useful for keeping files with different configuration information loaded on a network server. Router copy system:running-config nvram:startup-config. To configure the Cisco IOS software to download a host configuration file from a server at startup, complete the tasks in this section:.

The Cisco IOS software tries them in order entered until it loads one. In the following example, a router is configured to download the host configuration file named hostfile1 and the network configuration file named networkfile1. The router uses TFTP and the broadcast address to obtain the file. No new or modified standards are supported, and support for existing standards has not been modified.

Managing Configuration Files Last Updated: December 3, Creating, loading, and maintaining configuration files enable you to generate a set of user-configured commands to customize the functionality of your Cisco routing device.

Finding Feature Information Your software release may not support all the features documented in this module. The Cisco IOS software responds with the following prompt asking you to specify the terminal, memory, or a file stored on a network server network as the source of configuration commands: Configuring from terminal, memory, or network [terminal]? Copy a Configuration File from the Router to an rcp Server You can copy configuration file from the router to an rcp server.

Restrictions The rcp protocol requires a client to send a remote username on each rcp request to a server. When you copy a configuration file from the router to a server using rcp, the Cisco IOS software sends the first valid username it encounters in the following sequence: 1. For example, suppose the router contains the following configuration lines: hostname Rtr1 ip rcmd remote-username User0 If the router IP address translates to Router1.

This configuration guide contains Cisco IOS features that are supported in many different software release trains and onmany different platforms. Some of the features that are included in this configuration guide may not be supported in yourCisco IOS software release train. This configuration guide may contain information that is not specific to a particularplatform or release; however, platform differences and feature release information are included in this guide.
