AI2524 Router Card User’s Manual

Note:	Be sure there is enough available space before copying a
	file to Flash memory. Use the show flash command
	and compare the size of the file you want to copy to the
	amount of available Flash memory shown. If the space
	available is less than the space required by the file you
	want to copy, the copy process will continue, but the entire
	file will not be copied into Flash memory. The failure
	message buffer overflow - xxxx/ xxxx will
	appear, where xxxx/xxxx is the number of bytes read in
	relation to the number of bytes available.

When you enter the copy tftp flash command, the system prompts you for the IP address or domain name of the TFTP server. This server can be another router serving ROM or Flash system soft ware images. The system then prompts you for the filename of the software image to copy.

For the copy tftp flash and copy tftp file-idcom- mands, the router gives you the option of erasing the existing Flash memory before writing to it when there is space available to do so. If there is no free Flash memory available, or if the Flash memory has never been written to, you must run the erase routine before copying new files. The system will inform you of these conditions and prompt you for a response.

The file-idargument of the copy tftp file-idcommand specifies a device and filename as the destination of the copy opera- tion. You can omit the device, entering only copy tftp file- name. When you omit the device, the system uses the default device specified by th cd command.

If you try to copy a file into Flash memory and that file is already in Flash memory, a prompt informs you that a file with the same nam already exists. The new file replaces the existing file. The first copy o the file still resides within Flash memory, but it is rendered unusable in favor of the newer version, and is listed with the deleted tag when you use the show flash command. If you terminate the copy pro- cess, the newer file is marked deleted because the entire file was not copied and is invalid. In this case, the original file in Flash memory is still available to the system.
