supported.

IPv4 DHCP
Enabled
Enable the DHCPv4 client by checking this box. If this option is enabled, the
system will configure the IPv4 address and mask of the interface using the
DHCPv4 protocol. The DHCPv4 client will announce the configured System
Name as hostname to provide DNS lookup.
IPv4 DHCP
Fallback
Timeout
The number of seconds for trying to obtain a DHCP lease. After this period
expires, a configured IPv4 address will be used as IPv4 interface address. A
value of zero disables the fallback mechanism, such that DHCP will keep
retrying until a valid lease is obtained. Legal values are 0 to 4294967295
seconds.
IPv4 DHCP
Current
Lease
For DHCP interfaces with an active lease, this column shows the current
interface address as provided by the DHCP server.
IPv4

enabled, this field configures the fallback address. The field may be left blank if
IPv4 operation on the interface is not desired - or no DHCP fallback address is
desired.
