-
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 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 an 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. An 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 an 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 Duplicate Address Detection (DAD) 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.
