The IPv6 Interface Table on the IPv6 Interface Page displays the IPv6 interfaces defined on the selected Interface.
This table contains the following fields:
•
Check Box — Deletes the selected IPv6 interface. The first IPv6 interface entry displayed in the table is
read-only and represents the automatically generated Link Local IPv6 address that cannot be removed or
modified. The possible field values are:
–
Checked — Removes the selected IPv6 interface.
–
Unchecked — Maintains the IPv6 interface.
•
IPv6 Type — Defines the type of configurable static IPv6 IP address for an interface. The possible values are:
–
Link Local — Defines a Link Local address; non routable and can be used for communication on the
same network only. A Link Local address has a prefix of 'FE80'.
–
Global — Defines a globally unique IPv6 address; visible and reachable from different subnets.
•
IPv6 Address — Indicates the IPv6 address assigned to the interface. The address must be a valid IPv6
address, specified in hexadecimal using 16-bit values between colons. An example of an IPv6 address is
2031:0:130F:0:0:9C0:876A:130D and the compressed version is represented as 2031:0:0:9C0:876A:130D.
Up to five IP addresses can be set per interface, with the limitation of up to 128 addresses per system.
•
Prefix — Specifies the length of the IPv6 prefix. The length is a decimal value that indicates how many of the
high-order contiguous bits of the address comprise the prefix (the network portion of the address). The range
is 5 -128 (64 in the case EUI-64 parameter is used). The Prefix field is applicable only on a static IPv6
address defined as a Global IPv6 address.
•
DAD Status — Displays the DAD Status which is the process of verifying and assuring an inserted IPv6
address is unique. This is a read-only parameter with the following field values:
–
Tentative — Indicates the system is in process of IPv6 address duplication verification.
–
Duplicate — Indicates the IPv6 address is being used by an another host on the network. The duplicated
IPv6 address is suspended and is not used for sending or receiving any traffic.
–
Active — Indicates the IPv6 address is set to active.
