COPY FLASH TFTP
U can copy or backup image to server.
1 verify file SHOW FLASH and get name of file and then COPY FLASH TFTP command to copy image to TFTP server - files can be renamed for sever
U can copy image from TFTP to flash by COPY TFTP FLASH - you will be prompted to erase stored image, often there is only room for one image
each (!) means one UDP segmejnt has xferred OK
Use the SHOW FLASH command to compare size of file to server before changing boot commands to use new image
If you need to load the backup image, use a variation of command COPY TFTP FLASH
If you copy a file that is already there u will be prompted. The first copy of file is rendered unusable in favor of newer version
