To change the default name of the host configuration filename from which to load configuration commands, use the boot host global configuration command. Use the no form of this command to restore the host configuration filename to the default.
boot host remote-url
no boot host remote-url
remote-url Configures the router to boot the configuration file specified by the FTP, rcp, or TFTP URL:
- ftp: [[[// [username[: password]@ ]location]/ directory]/ filename]
- rcp: [[[// [username@ ]location]/ directory]/ filename]
- tftp: [[[// location]/ directory]/ filename]
The router uses its host name to form a host configuration filename. To form this name, the router converts its name to all lowercase letters, removes all domain information, and appends confg.

Use the service config command to enable the loading of the specified configuration file at reboot time. Without this command, the router ignores the boot host command and uses the configuration information in NVRAM. If the configuration information in NVRAM is invalid or missing, the serviceconfig command is enabled automatically.
The network server will attempt to load two configuration files from remote hosts. The first is the network configuration file containing commands that apply to all network servers on a network. Use the boot network command to identify the network configuration file. The second is the host configuration file containing commands that apply to one network server in particular. Use the boot host command to identify the host configuration file.
The rcp software requires that a client send the remote username on each rcp request to the network server. If the server has a directory structure (such as UNIX systems), the rcp implementation searches for the configuration files starting in the directory associated with the remote username.
When you load a configuration file from a server using rcp, the Cisco IOS software sends the first valid username in the following list:
An account for the username must be defined on the destination server. If the network administrator of the destination server did not establish an account for the username, this command will not execute successfully.
The FTP protocol requires a client to send a remote username and password on each FTP request to a server. The username and password must be associated with an account on the FTP server. If the server has a directory structure, the configuration file or image copied from the directory associated with the username on the server. Refer to the documentation for your FTP server for more details.
When you load a configuration file from a server using FTP, the Cisco IOS software sends the first valid username in the following list:
The router send the first valid password in the following list:
The following example sets the host filename to wilma-confg at address 192.168.7.19:
boot host tftp://192.168.7.19/usr/local/tftpdir/wilma-confg service config
| Command | Description |
|---|---|
| boot network | Changes the default name of the network configuration file from which to load configuration commands. |
| service config | Enables autoloading of configuration files from a network server, use the service config global configuration command. |
