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, 2001:1::90.
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 is supposed to be uniquely assigned. Once
the DAD (Duplicate Address Detection) detects the address
duplication, the operation on the interface SHOULD be disabled.
At this moment, manual intervention is required to resolve the address
duplication. For example, check whether the loop occurs in the VLAN
or there is indeed other device occupying the same hardware address
as the device in the VLAN.
After making sure the specific link-local address is unique on the IPv6
link in use, delete and then add the specific IPv6 interface to restart the
IPv6 operations on this interface.
