■ When using SFTP to copy a software image onto the switch, the command
return takes only a few seconds. However, this does not mean that the
transfer is complete, because the switch requires additional time (typi-
cally more than one minute) to write the image to flash in the background.
To verify the file transfer has been completed, you can use the show flash
command or look for a confirmation message in the log as in the following
example:
I 01/09/09 16:17:07 00150 update: Primary Image
updated.
Once you have configured your switch to enable secure file transfers with SCP
and SFTP, files can be copied to or from the switch in a secure (encrypted)
environment and TFTP is no longer necessary.
Troubleshooting SSH, SFTP, and SCP Operations
You can verify secure file transfer operations by checking the switch’s event
log, or by viewing the error messages sent by the switch that most SCP and
SFTP clients will print out on their console.
Note Messages that are sent by the switch to the client depend on the client software
in use to display them on the user console.
Broken SSH Connection. If an ssh connection is broken at the wrong
moment (for instance, the link goes away or spanning tree brings down the
link), a fatal exception would occur on the switch. If this happens, the switch
will gracefully exit the session and produce an event log message indicating
the cause of failure. The following three examples show the error messages
that may appear in the log depending on the type of session that is running
(SSH, SCP, or SFTP).
