Auto Configuration Download Protocol
The Auto Configuration download protocol can be configured, as follows:
Auto By File Extension—If this option is selected, you can provide a file extension
(the default file extension is scp). Files with the specified file extension are
downloaded using SCP (over SSH), while files with other extensions are
downloaded using TFTP. For example, if the file extension specified is .xyz, files
with the .xyz extension are downloaded using SCP, and files with the other
extensions are downloaded using TFTP. The default is Auto by file extension.
• TFTP Only—The download is done through TFTP regardless of the file
extension of the configuration file name.
• SCP Only—The download is done through SCP (over SSH) regardless of
the file extension of the configuration file name.
SSH Client Authentication Parameters
By default, remote ssh server authentication is disabled, so the device accepts
any remote ssh server out of the box. You can enable remote ssh server
authentication to allow connections only from servers in the trusted server list.
SSH Client Authentication parameters are required to access the SSH server by
the client (which is the switch). The default SSH Client authentication parameters
are:
• SSH Authentication method: by username/password
• SSH username: anonymous
• SSH password: anonymous
Note that the SSH Client authentication parameters can also be used when
downloading a file for manual download (a download that is not performed
through the DHCP Auto Configuration feature).
