• Download Protocol— Select one of the following options:
- Auto By File Extension —Select to indicate that auto configuration uses
the TFTP or SCP protocol depending on the extension of the
configuration file. If this option is selected, the extension of the
configuration file does not necessarily have to be given. If it is not given,
the default extension is used (as indicated below).
-
File Extension for SCP
—If Auto By File Extension is selected, you can
indicate a file extension here. Any file with this extension is downloaded
using SCP. If no extension is entered, the default file extension.scp is
used.
- TFTP Only —Select to indicate that only the TFTP protocol is to be used
for auto configuration.
-
SCP Only
—Select to indicate that only the SCP protocol is to be used for
auto configuration.
• SSH Settings for SCP— When using SCP for downloading the configuration
files, select one of the following options:
-
Remote SSH Server Authentication
—Click on the Enable/Disable link to
navigate to the SSH Server Authentication page. There you can enable
authentication of the SSH server to be used for the download and enter
the trusted SSH server if required.

Enter the following optional information to be used if no configuration file name
was received from the DHCP server.
• Backup Server Definition— Select By IP address or By name to configure
the server.
• IP Version —Select whether an IPv4 or an IPv6 address is used.
• IPv6 Address Type —Select the IPv6 address type (if IPv6 is used). The
options are:
- Link Local—The IPv6 address uniquely identifies hosts on a single
network link. A link local address has a prefix of FE80, is not routable, and
can be used for communication only on the local network. Only one link
local address is supported. If a link local address exists on the interface,
this entry replaces the address in the configuration.
