Management and Configuration Guide K/KA/KB.15.15

switch needs are already in place on the switch. You do not need to (nor can you) create new
files.
• The switch supports one SFTP session or one SCP session at a time.
• All files have read-write permission. Several SFTP commands, such as create or remove,
are not allowed and return an error message. The switch displays the following files:

• 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 (typically 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.
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 print out on their console.
