is this the result of a tftpdnld ?? This happened to me a long while back and I had to set a variable to tell it to ignore the checksum. I was using a 2600 though.
Here is the skinny from CCO: You can view the ROMMON environment variables by using the set command, as shown below: rommon 3 > set PS1=rommon ! > IP_ADDRESS=172.18.16.76 IP_SUBNET_MASK=255.255.255.192 DEFAULT_GATEWAY=172.18.16.65 TFTP_SERVER=172.18.16.2 TFTP_FILE=quake/rel22_Jan_16/c2600-i-mz The variables to set for tftpdnld are shown below: usage: tftpdnld Use this command for disaster recovery only to recover an image via TFTP. "tftpdnld" has no arguments. Monitor variables are used for arguments. (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=7) TFTP_TIMEOUT: Overall timeout of operation in seconds (default=2400) TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes (default=1) rommon 14 > ************************* check out TFTP_CHECKSUM and set it to 0 remember, all the variables must be entered in upper case. Once I set that, the image went in fine. Kevin Wigle ----- Original Message ----- From: "Gareth Hinton" To: Sent: Friday, 02 November, 2001 19:55 Subject: 2500 IOS TFTP Problem - For a change!
