Note

•Because ftp-related commands such as ls command cannot show any file to be obtained, the file sizes cannot be determined in advance.

•Fetching the information takes a long time because the command is processed on the system. However, do not cancel the process on the way.

•The loading state of the system or condition of the communication path might cause a network timeout, which makes the client disconnect a line. In this case, set a longer period of time for the client timeout.

•Failure information obtained via ftp does not contain the results of executing the system administrator commands such as show running-configcommand.

•Executing the show tech-supportcommand records "ftpuser" as a user name in the log information.
