This table is used to describe the mapping between the physical address and the IPv6 address on the network device.

The indexes of this table are ipv6IfIndex and ipv6NetToMediaNetAddress.


Object Name


Max Access


Implemented Specifications




This object indicates the IPv6 address corresponding to the media dependent physical address.

The fixed length is 16 bytes.

This object is implemented as defined in the corresponding MIB files.




This object indicates the media-dependent physical address.

This object is implemented as defined in the corresponding MIB files.




The value of this object identifies the mapping type.

The values are as follows:

  • other(1)
  • dynamic(2): the IPv6 address to physical addresses mapping has been dynamically resolved using the IPv6 Neighbor Discovery protocol
  • static(3): the mapping has been statically configured
  • local(4): the mapping is provided for an entity's own interface address

Currently, the return value dynamic(2) and static(3) are supported only.




The value of this object identifies the status of the neighbor unreachability detection for the interface when the address mapping in this entry is used.

Currently, the return value invaild(5) is not supported.




The value of this object identifies the value of sysUpTime when this entry is last updated.

If this entry was updated prior to the last re-initialization of the local network management subsystem, then this object contains a zero value.

This object is implemented as defined in the corresponding MIB files.




Setting this object to the value 'false(2)' has the effect of invalidating the corresponding entry in the ipv6NetToMediaTable.

That is, it effectively disassociates the interface identified with said entry from the mapping identified with said entry.

It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive tabular information from agents that corresponds to entries not currently in use.

Proper interpretation of such entries requires examination of the relevant ipv6NetToMediaValid object.

Currently, the maximum access is read-only; the return value true(1) is supported only.

Creation Restriction

No entry can be created in this table.

Modification Restriction

The entries in this table cannot be modified.

Deletion Restriction

The entries in this table cannot be deleted.

Access Restriction

The interface supports the IPv6 function. Some interfaces do not need this mapping table. If all the interfaces do not need the mapping table, the mapping table is empty; that is, the number of entries is 0.
