IMPORTANT: If you plan to run webclient or ftp over the same interface, you do not need to
use the Embedded UEFI Shell ifconfig command on a network interface. The Pre-Boot
Network Settings configured in the System Utilities automatically selects these interface.
If the interface used by ftp and webclient are configured by ifconfig, that setting is erased.
Instead, the System Utilities Pre-Boot Network Settings menu is applied on the interface when the
commands are run.
• Pre-Boot Network Interface—Specifies the network interface used for preboot network connections.
◦ Auto (default)—The system uses the first available port with a network connection.
◦ Select Specific Port — The system uses the selected NIC port.
• DCHPv4—Enables or disables obtaining the preboot network IPv4 configuration from a DHCP server
for Network operations from the Embedded UEFI Shell.
◦ Enabled—Enables DHCPv4 network address configuration. Individual settings are not available.
◦ Disabled—Disables DHCPv4 address configuration, requiring you to configure the following static
IP address settings manually.
– IPv4 Address
– IPv4 Subnet Mask
– IPv4 Gateway
– IPv4 Primary DNS
– IPv4 Secondary DNS
• Preboot Network Proxy—Specifies a preboot network proxy. When set, network operations for the
Pre-Boot Network Interface are attempted through the configured proxy. The proxy must be in an
HTTP URL format, and can be specified as http://IPv4_address:port, http://
[IPv6_address]:port or http://FQDN:port.
• IPv6 Config Policy
◦ Automatic—Enables preboot network IPv6 configuration to be automatically obtained for Network
operations from the Embedded UEFI Shell. Individual settings are not available.
◦ Manual—Enables you to configure static IP address settings individually.
• Boot from URL 1, 2, 3 or 4—Specifies a network URL to a bootable ISO or EFI file. Enter a URL in
either HTTP or HTTPS format, using either an IPv4 or IPv6 server address or host name. For
example, the URLs can be in any of the following formats: http://192.168.0.1/file/
image.iso, http://example.com/file/image.efi, https://example.com/file/
image.efi, http://[1234::1000]/image.iso. When configured, this URL is listed as a boot
option in the UEFI Boot menu. Then you can select this option from the boot menu to download the
specified file to the system memory and enable the system to boot from the file.
