interface. This field is only available for input when creating a new interface.
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 show the current interface address, as
provided by the DHCP server.
IPv4 Address
The IPv4 address of the interface in dotted decimal notation.
If DHCP is 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.
IPv4 Mask
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and 30 bits
for a IPv4 address.
If DHCP is enabled, this field configures the fallback address network mask. The field may be left
blank if IPv4 operation on the interface is not desired - or no DHCP fallback address is desired.
DHCPv6 Enable
Enable the DHCPv6 client by checking this box. If this option is enabled, the system will configure
the IPv6 address of the interface using the DHCPv6 protocol.
DHCPv6 Rapid Commit
Enable the DHCPv6 Rapid-Commit option by checking this box. If this option is enabled, the
DHCPv6 client terminates the waiting process as soon as a Reply message with a Rapid Commit
option is received.
This option is only manageable when DHCPv6 client is enabled.
DHCPv6 Current Lease
For DHCPv6 interface with an active lease, this column shows the interface address provided by
the DHCPv6 server.
IPv6 Address
The IPv6 address of the interface. A IPv6 address is in 128-bit records represented as eight fields
of up to four hexadecimal digits with a colon separating each field (:). For
example,fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that can be used as a shorthand
way of representing multiple 16-bit groups of contiguous zeros; but it can appear only once.
System accepts the valid IPv6 unicast address only, except IPv4-Compatible address and
IPv4-Mapped address.
The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask
The IPv6 network mask, in number of bits (prefix length). Valid values are between 1 and 128 bits
for a IPv6 address.
The field may be left blank if IPv6 operation on the interface is not desired.
Resolving IPv6 DAD
The link-local address is formed from an interface identifier based on the hardware address which
