configuration file. In this case, if the local configuration file does not exist, then it is created by the command. If it does exist, it is overwritten. If there is not enough space on the local file system to accommodate the file, an error is flagged. Refer to the copy command description in the Layer 2 commands section of the guide for command details. Referencing External/Internal File systems Configuration or software images are copied to or retrieved from remote file systems using TFTP and XMODEM protocols. • tftp://server-name/path/filename - identifies a file on a remote file system accessible through the server-name. Trivial file transfer protocol is a simplified FTP and uses a UDP port instead of TCP and does not have password protection. • xmodem: filename - identifies the file available on the XMODEM connection. Special System Files The following special filenames are used to refer to special virtual system files, which are under control of the system and may not be removed or added. These file names are reserved and may not be used as user-defined files. When the user copies a local source file into one of these special files and the source file has an attached file description, it also is copied as the file description for the special file. • backup-config - This file refers to the backup configuration file. • running-config - This file refers to the configuration file currently active in the system. It is possible to copy the running-config image to a backupconfig file or to the startup-config file. • startup-config - This file refers to the special configuration image stored in flash memory which is loaded when the system next reboots. The user may copy a particular configuration file (remote or local) to this special file name and reboot the system to force it to use a particular configuration. • image1 & image2 - These files refer to software images. One of these will be loaded when the system next reboots. Either image1 or image2 can be chosen for the next reboot using the command boot system. 166 Using the CLI
