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.
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.
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.
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.
• IP Routes Delete
Select this option to delete an existing IP route.
Network
The destination IP network or host address of this route. Valid format is
dotted decimal notation or a valid IPv6 notation. A default route can use
the value 0.0.0.0 or IPv6 :: notation.
Mask Length
The destination IP network or host mask, in number of bits (prefix
length). It defines how much of a network address that must match, in
order to qualify for this route. Valid values are between 0 and 32
bitsrespectively 128 for IPv6 routes. Only a default route will have a
mask length of 0 (as it will match anything).
Gateway
The IP address of the IP gateway. Valid format is
dotted decimal
notation or a valid IPv6 notation. Gateway and Network must be of the
same type.
