rommon 37 > tftpdnld -hMissing or illegal ip address for variable IP_ADDRESS Illegal IP address.
usage: tftpdnld [-hr] Use this command for disaster recovery only to recover an image via TFTP. Monitor variables are used to set up parameters for the transfer. (Syntax: "VARIABLE_NAME=value" and use "set" to show current variables.) "ctrl-c" or "break" stops the transfer before flash erase begins.
The following variables are REQUIRED to be set for tftpdnld: IP_ADDRESS: The IP address for this unit IP_SUBNET_MASK: The subnet mask for this unit DEFAULT_GATEWAY: The default gateway for this unit TFTP_SERVER: The IP address of the server to fetch from TFTP_FILE: The filename to fetch
The following variables are OPTIONAL: TFTP_VERBOSE: Print setting. 0=quiet, 1=progress(default), 2=verbose TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=18) TFTP_TIMEOUT: Overall timeout of operation in seconds (default=7200) TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes (default=1) FE_PORT: 0(default), 1 FE_SPEED_MODE: 0=10/hdx, 1=10/fdx, 2=100/hdx, 3=100/fdx, 4=Auto (default)
Command line options: -h: this help screen -r: do not write flash, load to DRAM only and launch image
