Name	Type	Access	OID	Description

TABLE OBJECTS

DEPRECATED OR OBSOLETE OR HISTORIC OBJECTS

SCALAR OBJECTS

Value	Label/Meaning
1	forwarding
2	notForwarding

ReadWrite

The indication of whether this entity is acting
as an IPv6 router in respect to the forwarding of
datagrams received by, but not addressed to, this
entity.  IPv6 routers forward datagrams.  IPv6
hosts do not (except those source-routed via the
host).

Note that for some managed nodes, this object may
take on only a subset of the values possible.
Accordingly, it is appropriate for an agent to
return a `wrongValue' response if a management
station attempts to change this object to an
inappropriate value.

This object is obsoleted by IP-MIB::ipv6IpForwarding.

2
ipv6DefaultHopLimit

DEPRECATED
INTEGER
Legal values: 0 .. 255

ReadWrite

The default value inserted into the Hop Limit
field of the IPv6 header of datagrams originated
at this entity, whenever a Hop Limit value is not
supplied by the transport layer protocol.

This object is obsoleted by IP-MIB::ipv6IpDefaultHopLimit.

3
ipv6Interfaces

DEPRECATED
UNSIGNED32

ReadOnly

The number of IPv6 interfaces (regardless of
their current state) present on this system.

This object is obsolete; there is no direct replacement,
but its value can be derived from the number of rows
in the IP-MIB::ipv6InterfaceTable.

4
ipv6IfTableLastChange

DEPRECATED
TICKS
TimeStamp

ReadOnly

Note: this object is based on the TimeStamp TEXTUAL-CONVENTION.

The value of sysUpTime at the time of the last
insertion or removal of an entry in the
ipv6IfTable.  If the number of entries has been
unchanged since the last re-initialization of
the local network management subsystem, then this
object contains a zero value.

This object is obsoleted by
IP-MIB::ipv6InterfaceTableLastChange.

9
ipv6RouteNumber

DEPRECATED
GAUGE

ReadOnly

The number of current ipv6RouteTable entries.
This is primarily to avoid having to read
the table in order to determine this number.

This object is obsoleted by IP-FORWARD-MIB::inetCidrRouteNumber.

10
ipv6DiscardedRoutes

DEPRECATED
COUNTER

ReadOnly

The number of routing entries which were chosen
to be discarded even though they are valid.  One
        possible reason for discarding such an entry could
        be to free-up buffer space for other routing
        entries.
This object is obsoleted by
        IP-FORWARD-MIB::inetCidrRouteDiscards.

TABLE OBJECTS

Table ipv6IfTable

Table Name	ipv6IfTable
In MIB	IPV6-MIB
Registered at OID	.1.3.6.1.2.1.55.1.5
Table Description	The IPv6 Interfaces table contains information on the entity's internetwork-layer interfaces. An IPv6 interface constitutes a logical network layer attachment to the layer immediately below IPv6 including internet layer 'tunnels', such as tunnels over IPv4 or IPv6 itself. This table is obsoleted by IP-MIB::ipv6InterfaceTable.
Row Description	An interface entry containing objects about a particular IPv6 interface. This object is obsoleted by IP-MIB::ipv6InterfaceEntry.

ipv6IfTable Indexes:

1
ipv6IfIndex

DEPRECATED
INTEGER32
Legal values: 1 .. 2147483647
Ipv6IfIndex

NoAccess

Note: this object is based on the Ipv6IfIndex TEXTUAL-CONVENTION.

A unique non-zero value identifying
the particular IPv6 interface.

This object is obsoleted.  In the IP-MIB,
interfaces are simply identified by IfIndex.

Other ipv6IfTable Columns:

2
ipv6IfDescr

DEPRECATED
OCTETSTR
Legal Lengths: 0 .. 255
DisplayString

ReadWrite

Note: this object is based on the DisplayString TEXTUAL-CONVENTION.

A textual string containing information about the
interface.  This string may be set by the network
management system.

This object is obsoleted by IF-MIB::ifDescr.

3
ipv6IfLowerLayer

DEPRECATED
OBJECTID
VariablePointer

ReadOnly

Note: this object is based on the VariablePointer TEXTUAL-CONVENTION.

This object identifies the protocol layer over
which this network interface operates.  If this
network interface operates over the data-link
layer, then the value of this object refers to an
instance of ifIndex [RFC1573].  If this network interface
operates over an IPv4 interface, the value of this
object refers to an instance of ipAdEntAddr [RFC1213].

If this network interface operates over another
IPv6 interface, the value of this object refers to
an instance of ipv6IfIndex.  If this network
interface is not currently operating over an active
protocol layer, then the value of this object
should be set to the OBJECT ID { 0 0 }.

This object is obsolete.  The IF-STACK-TABLE may
be used to express relationships between interfaces.

4
ipv6IfEffectiveMtu

DEPRECATED
UNSIGNED32

ReadOnly

The size of the largest IPv6 packet which can be
sent/received on the interface, specified in
octets.

This object is obsolete.  The value of IF-MIB::ifMtu
for the corresponding value of ifIndex represents the
MTU of the interface.

5
ipv6IfReasmMaxSize

DEPRECATED
UNSIGNED32
Legal values: 0 .. 65535

ReadOnly

The size of the largest IPv6 datagram which this
entity can re-assemble from incoming IPv6 fragmented
datagrams received on this interface.

This object is obsoleted by IP-MIB::ipv6InterfaceReasmMaxSize.

6
ipv6IfIdentifier

DEPRECATED
OCTETSTR
Legal Lengths: 0 .. 8
Ipv6AddressIfIdentifier

ReadWrite

Note: this object is based on the Ipv6AddressIfIdentifier TEXTUAL-CONVENTION.

The Interface Identifier for this interface that
is (at least) unique on the link this interface is
attached to.  The Interface Identifier is combined
with an address prefix to form an interface address.

By default, the Interface Identifier is autoconfigured
according to the rules of the link type this
interface is attached to.

This object is obsoleted by IP-MIB::ipv6InterfaceIdentifier.

7
ipv6IfIdentifierLength

DEPRECATED
INTEGER
Legal values: 0 .. 64

ReadWrite

The length of the Interface Identifier in bits.
This object is obsolete.  It can be derived from the length
       of IP-MIB::ipv6InterfaceIdentifier; Interface Identifiers
       that are not an even number of octets are not supported.

8
ipv6IfPhysicalAddress

DEPRECATED
OCTETSTR
PhysAddress

ReadOnly

Note: this object is based on the PhysAddress TEXTUAL-CONVENTION.

The interface's physical address.  For example, for
an IPv6 interface attached to an 802.x link, this
object normally contains a MAC address.  Note that
in some cases this address may differ from the
address of the interface's protocol sub-layer.  The
interface's media-specific MIB must define the bit
and byte ordering and the format of the value of
this object.  For interfaces which do not have such
an address (e.g., a serial line), this object should
contain an octet string of zero length.

This object is obsoleted by IF-MIB::ifPhysAddress.

9
ipv6IfAdminStatus

DEPRECATED
INTEGER

Value	Label/Meaning
1	up
2	down

ReadWrite

The desired state of the interface.  When a managed
system initializes, all IPv6 interfaces start with
ipv6IfAdminStatus in the down(2) state.  As a result
of either explicit management action or per
configuration information retained by the managed
system, ipv6IfAdminStatus is then changed to
the up(1) state (or remains in the down(2) state).

This object is obsolete.  IPv6 does not have a
separate admin status; the admin status of the
interface is represented by IF-MIB::ifAdminStatus.

10
ipv6IfOperStatus

DEPRECATED
INTEGER

Value	Label/Meaning
1	up
2	down
3	noIfIdentifier
4	unknown
5	notPresent

ReadOnly

The current operational state of the interface.
The noIfIdentifier(3) state indicates that no valid
Interface Identifier is assigned to the interface.
This state usually indicates that the link-local
interface address failed Duplicate Address Detection.
If ipv6IfAdminStatus is down(2) then ipv6IfOperStatus
should be down(2).  If ipv6IfAdminStatus is changed
to up(1) then ipv6IfOperStatus should change to up(1)
if the interface is ready to transmit and receive
network traffic; it should remain in the down(2) or
noIfIdentifier(3) state if and only if there is a
fault that prevents it from going to the up(1) state;
it should remain in the notPresent(5) state if
the interface has missing (typically, lower layer)
components.

This object is obsolete.  IPv6 does not have a
separate operational status; the operational status of the
interface is represented by IF-MIB::ifOperStatus.

11
ipv6IfLastChange

DEPRECATED
TICKS
TimeStamp

ReadOnly

Note: this object is based on the TimeStamp TEXTUAL-CONVENTION.

The value of sysUpTime at the time the interface
entered its current operational state.  If the
current state was entered prior to the last
re-initialization of the local network management
subsystem, then this object contains a zero
value.

This object is obsolete.  The last change of
IF-MIB::ifOperStatus is represented by IF-MIB::ifLastChange.

interfaces are simply identified by IfIndex.

Other ipv6IfStatsTable Columns:

Name	Type	Access	Description
1 ipv6IfStatsInReceives	DEPRECATED COUNTER	ReadOnly	The total number of input datagrams received by the interface, including those received in error. This object is obsoleted by IP-MIB::ipIfStatsHCInReceives.
2 ipv6IfStatsInHdrErrors	DEPRECATED COUNTER	ReadOnly	The number of input datagrams discarded due to errors in their IPv6 headers, including version number mismatch, other format errors, hop count exceeded, errors discovered in processing their IPv6 options, etc. This object is obsoleted by IP-MIB::ipIfStatsInHdrErrors.
3 ipv6IfStatsInTooBigErrors	DEPRECATED COUNTER	ReadOnly	The number of input datagrams that could not be forwarded because their size exceeded the link MTU of outgoing interface. This object is obsoleted. It was not replicated in the IP-MIB due to feedback that systems did not retain the incoming interface of a packet that failed fragmentation.
4 ipv6IfStatsInNoRoutes	DEPRECATED COUNTER	ReadOnly	The number of input datagrams discarded because no route could be found to transmit them to their destination. This object is obsoleted by IP-MIB::ipIfStatsInNoRoutes.
5 ipv6IfStatsInAddrErrors	DEPRECATED COUNTER	ReadOnly	The number of input datagrams discarded because the IPv6 address in their IPv6 header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (e.g., ::0) and unsupported addresses (e.g., addresses with unallocated prefixes). For entities which are not IPv6 routers and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address. This object is obsoleted by IP-MIB::ipIfStatsInAddrErrors.
6 ipv6IfStatsInUnknownProtos	DEPRECATED COUNTER	ReadOnly	The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol. This counter is incremented at the interface to which these datagrams were addressed which might not be necessarily the input interface for some of the datagrams.

7 ipv6IfStatsInTruncatedPkts	DEPRECATED COUNTER	ReadOnly	The number of input datagrams discarded because datagram frame didn't carry enough data. This object is obsoleted by IP-MIB::ipIfStatsInTruncatedPkts.
8 ipv6IfStatsInDiscards	DEPRECATED COUNTER	ReadOnly	The number of input IPv6 datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (e.g., for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly. This object is obsoleted by IP-MIB::ipIfStatsInDiscards.
9 ipv6IfStatsInDelivers	DEPRECATED COUNTER	ReadOnly	The total number of datagrams successfully delivered to IPv6 user-protocols (including ICMP). This counter is incremented at the interface to which these datagrams were addressed which might not be necessarily the input interface for some of the datagrams. This object is obsoleted by IP-MIB::ipIfStatsHCInDelivers.
10 ipv6IfStatsOutForwDatagrams	DEPRECATED COUNTER	ReadOnly	The number of output datagrams which this entity received and forwarded to their final destinations. In entities which do not act as IPv6 routers, this counter will include only those packets which were Source-Routed via this entity, and the Source-Route processing was successful. Note that for a successfully forwarded datagram the counter of the outgoing interface is incremented. This object is obsoleted by IP-MIB::ipIfStatsHCOutForwDatagrams.
11 ipv6IfStatsOutRequests	DEPRECATED COUNTER	ReadOnly	The total number of IPv6 datagrams which local IPv6 user-protocols (including ICMP) supplied to IPv6 in requests for transmission. Note that this counter does not include any datagrams counted in ipv6IfStatsOutForwDatagrams. This object is obsoleted by IP-MIB::ipIfStatsHCOutRequests.
12 ipv6IfStatsOutDiscards	DEPRECATED COUNTER	ReadOnly	The number of output IPv6 datagrams for which no problem was encountered to prevent their transmission to their destination, but which were discarded (e.g., for lack of buffer space). Note that this counter would include datagrams counted in ipv6IfStatsOutForwDatagrams if any such packets met this (discretionary) discard criterion. This object is obsoleted by IP-MIB::ipIfStatsOutDiscards.
13 ipv6IfStatsOutFragOKs	DEPRECATED COUNTER	ReadOnly	The number of IPv6 datagrams that have been successfully fragmented at this output interface. This object is obsoleted by IP-MIB::ipIfStatsOutFragOKs.
14 ipv6IfStatsOutFragFails	DEPRECATED COUNTER	ReadOnly	The number of IPv6 datagrams that have been discarded because they needed to be fragmented at this output interface but could not be. This object is obsoleted by IP-MIB::ipIfStatsOutFragFails.
15 ipv6IfStatsOutFragCreates	DEPRECATED COUNTER	ReadOnly	The number of output datagram fragments that have been generated as a result of fragmentation at this output interface. This object is obsoleted by IP-MIB::ipIfStatsOutFragCreates.
16 ipv6IfStatsReasmReqds	DEPRECATED COUNTER	ReadOnly	The number of IPv6 fragments received which needed to be reassembled at this interface. Note that this counter is incremented at the interface to which these fragments were addressed which might not be necessarily the input interface for some of the fragments. This object is obsoleted by IP-MIB::ipIfStatsReasmReqds.
17 ipv6IfStatsReasmOKs	DEPRECATED COUNTER	ReadOnly	The number of IPv6 datagrams successfully reassembled. Note that this counter is incremented at the interface to which these datagrams were addressed which might not be necessarily the input interface for some of the fragments. This object is obsoleted by IP-MIB::ipIfStatsReasmOKs.
18 ipv6IfStatsReasmFails	DEPRECATED COUNTER	ReadOnly	The number of failures detected by the IPv6 re- assembly algorithm (for whatever reason: timed out, errors, etc.). Note that this is not necessarily a count of discarded IPv6 fragments since some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received. This counter is incremented at the interface to which these fragments were addressed which might not be necessarily the input interface for some of the fragments. This object is obsoleted by IP-MIB::ipIfStatsReasmFails.
19 ipv6IfStatsInMcastPkts	DEPRECATED COUNTER	ReadOnly	The number of multicast packets received by the interface This object is obsoleted by IP-MIB::ipIfStatsHCInMcastPkts.
20 ipv6IfStatsOutMcastPkts	DEPRECATED COUNTER	ReadOnly	The number of multicast packets transmitted by the interface This object is obsoleted by IP-MIB::ipIfStatsHCOutMcastPkts.

to zero.

This object is obsolete, and it has no replacement.
The Routing Domain ID concept did not catch on.

11
ipv6RouteMetric

DEPRECATED
UNSIGNED32

ReadOnly

The routing metric for this route.  The
semantics of this metric are determined by the
routing protocol specified in the route's

DEPRECATED
INTEGER
TruthValue
(ENUM list below)

ReadWrite

Note: this object is based on the TruthValue TEXTUAL-CONVENTION.

Setting this object to the value 'false(2)' has
the effect of invalidating the corresponding entry
in the ipv6RouteTable object.  That is, it
effectively disassociates the destination
identified with said entry from the route
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 ipv6RouteValid
object.

IP-FORWARD-MIB::inetCidrRouteStatus.

Table ipv6NetToMediaTable

Table Name	ipv6NetToMediaTable
In MIB	IPV6-MIB
Registered at OID	.1.3.6.1.2.1.55.1.12
Table Description	The IPv6 Address Translation table used for mapping from IPv6 addresses to physical addresses. The IPv6 address translation table contain the Ipv6Address to `physical' address equivalencies. Some interfaces do not use translation tables for determining address equivalencies; if all interfaces are of this type, then the Address Translation table is empty, i.e., has zero entries. This table is obsoleted by IP-MIB::ipNetToPhysicalTable.
Row Description	Each entry contains one IPv6 address to `physical' address equivalence. This entry is obsoleted by IP-MIB::ipNetToPhysicalEntry.

ipv6NetToMediaType

DEPRECATED
INTEGER

Value	Label/Meaning
1	other
2	dynamic
3	static
4	local

ReadOnly

The type of the mapping.  The 'dynamic(2)' type
indicates that the IPv6 address to physical
addresses mapping has been dynamically
resolved using the IPv6 Neighbor Discovery
protocol.  The static(3)' types indicates that
the mapping has been statically configured.
The local(4) indicates that the mapping is
provided for an entity's own interface address.

This object is obsoleted by IP-MIB::ipNetToPhysicalType.

5	invalid
6	unknown

ReadOnly

The Neighbor Unreachability Detection [RFC2461] state
for the interface when the address mapping in
this entry is used.

This object is obsoleted by IP-MIB::ipNetToPhysicalState.

ipv6IfNetToMediaLastUpdated

DEPRECATED
TICKS
TimeStamp

ReadOnly

Note: this object is based on the TimeStamp TEXTUAL-CONVENTION.

The value of sysUpTime at the time this entry
was 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 obsoleted by IP-MIB::ipNetToPhysicalLastUpdated.

ipv6NetToMediaValid

DEPRECATED
INTEGER
TruthValue
(ENUM list below)

ReadWrite

Note: this object is based on the TruthValue TEXTUAL-CONVENTION.

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.

This object is obsoleted by IP-MIB::ipNetToPhysicalRowStatus.

NOTIFICATIONS

Notification: ipv6IfStateChange

.1.3.6.1.2.1.55.2.0.1

Notification Description

An ipv6IfStateChange notification signifies
that there has been a change in the state of
an ipv6 interface.  This notification should
be generated when the interface's operational
status transitions to or from the up(1) state.

This object is obsoleted by IF-MIB::linkUp
and IF-MIB::linkDown notifications.

TEXTUAL CONVENTIONS

These TEXTUAL-CONVENTIONS are used in other parts of the document above. They are SNMP's way of defining a datatype that is used repeatedly by other MIB objects. Any implementation implementing objects that use one of these definitions must follow its DESCRIPTION clause as well as the DESCRIPTION clause of the object itself.

A unique value, greater than zero for each
internetwork-layer interface in the managed
system.  It is recommended that values are assigned
contiguously starting from 1.  The value for each
internetwork-layer interface must remain constant
at least from one re-initialization of the entity's
network management system to the next
re-initialization.

This object is obsoleted by IF-MIB::InterfaceIndex.

PhysAddress

OCTETSTR

Represents media- or physical-level addresses.

TruthValue

INTEGER

Value	Label/Meaning
1	true
2	false

Represents a boolean value.

Ipv6Address

OCTETSTR

This data type is used to model IPv6 addresses.
This is a binary string of 16 octets in network
byte-order.

This object is obsoleted by INET-ADDRESS-MIB::InetAddress.

Ipv6AddressPrefix

OCTETSTR

This data type is used to model IPv6 address
prefixes.  This is a binary string of up to 16
octets in network byte-order.
This object is obsoleted by INET-ADDRESS-MIB::InetAddress.

TimeStamp

TICKS

The value of the sysUpTime object at which a specific
occurrence happened.  The specific occurrence must be

defined in the description of any object defined using this
type.

If sysUpTime is reset to zero as a result of a re-
initialization of the network management (sub)system, then
the values of all TimeStamp objects are also reset.
However, after approximately 497 days without a re-
initialization, the sysUpTime object will reach 2^^32-1 and
then increment around to zero; in this case, existing values
of TimeStamp objects do not change.  This can lead to
ambiguities in the value of TimeStamp objects.

VariablePointer

OBJECTID

A pointer to a specific object instance.  For example,
sysContact.0 or ifInOctets.3.

Ipv6AddressIfIdentifier

OCTETSTR

This data type is used to model IPv6 address
interface identifiers.  This is a binary string
 of up to 8 octets in network byte-order.

This object is obsoleted by IP-MIB::Ipv6AddressIfIdentifierTC.

Ipv6IfIndexOrZero

INTEGER32

This textual convention is an extension of the
Ipv6IfIndex convention.  The latter defines
a greater than zero value used to identify an IPv6
interface in the managed system.  This extension
permits the additional value of zero.  The value
zero is object-specific and must therefore be
defined as part of the description of any object
which uses this syntax.  Examples of the usage of
zero might include situations where interface was
unknown, or when none or all interfaces need to be
referenced.

This object is obsoleted by IF-MIB::InterfaceIndexOrZero.

DisplayString

OCTETSTR

Represents textual information taken from the NVT ASCII
character set, as defined in pages 4, 10-11 of RFC 854.
To summarize RFC 854, the NVT ASCII repertoire specifies:
  - the use of character codes 0-127 (decimal)
  - the graphics characters (32-126) are interpreted as
                US ASCII
  - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
                meanings specified in RFC 854
  - the other 25 codes have no standard interpretation
  - the sequence 'CR LF' means newline
  - the sequence 'CR NUL' means carriage-return
  - an 'LF' not preceded by a 'CR' means moving to the
                same column on the next line.
  - the sequence 'CR x' for any x other than LF or NUL is
                illegal.  (Note that this also means that a string may
                end with either 'CR LF' or 'CR NUL', but not with CR.)
Any object defined using this syntax may not exceed 255
            characters in length.

RowPointer

OBJECTID

Represents a pointer to a conceptual row.  The value is the
name of the instance of the first accessible columnar object
in the conceptual row.

For example, ifIndex.3 would point to the 3rd row in the
ifTable (note that if ifIndex were not-accessible, then
ifDescr.3 would be used instead).
