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 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.
