From this DHCPv4 interface
: Specify from which DHCPv4-enabled interface a provided DNS server
should be preferred.
From any DHCPv6 interfaces
: The first DNS server offered from a DHCPv6 lease to a DHCPv6-enabled
interface will be used.
From this DHCPv6 interface
: Specify from which DHCPv6-enabled interface a provided DNS server
should be preferred.
DNS Proxy
: When DNS proxy is enabled, system will relay DNS requests to the currently configured DNS server,
and reply as a DNS resolver to the client devices on the network. Only IPv4 DNS proxy is now supported.
IP Interfaces
Delete
: Select this option to delete an existing IP interface.
VLAN
: The VLAN associated with the IP interface. Only ports in this VLAN will be able to access the IP interface.
This field is only available for input when creating a new interface.
IPv4 DHCP Enabled
: Enable the DHCP client by checking this box. If this option is enabled, the system will
configure the IPv4 address and mask of the interface using the DHCP protocol.
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, so 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 Address
: The IPv4 address of the interface in dotted decimal notation. If DHCP is enabled, this field is not
used. The field may also be left bank if IPv4 operation on the interface is not desired.
IPv4 Mask Length
: 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 is not used. The field may also be left blank if IPv4 operation
on the interface is not 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. It can also represent a legally valid IPv4 address. For example,
::192.1.2.34. The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask Length
: 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.
