I have followed the procedures in the MultiVantage Documentation but it must not include enough information. I am getting the following indications when I do a display tftp-swerver command. File Status: No file in ACP memory File size: 0 and Filename in Memory: blank. Then after a short period if I issue the same command display tft-server the File Status changes to: TFTP error: TFTP server unreachable. I am able to ping the server address from the Definity. I am not sure if I placed the new updated bin file in the proper location or directory on the tftp server. If anyone is familiar with how to do this I would appreciate any details on making this work.
