SCALAR OBJECTS

Name	Type	Access	OID	Description
1 ipv6Forwarding	INTEGER Value Label/Meaning 1 forwarding 2 notForwarding	ReadWrite	.1.3.6.1.2.1.55.1.1	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.
2 ipv6DefaultHopLimit	INTEGER Legal values: 0 .. 255	ReadWrite	.1.3.6.1.2.1.55.1.2	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.
3 ipv6Interfaces	UNSIGNED32	ReadOnly	.1.3.6.1.2.1.55.1.3	The number of IPv6 interfaces (regardless of their current state) present on this system.
4 ipv6IfTableLastChange	TICKS TimeStamp	ReadOnly	.1.3.6.1.2.1.55.1.4	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.
9 ipv6RouteNumber	GAUGE	ReadOnly	.1.3.6.1.2.1.55.1.9	The number of current ipv6RouteTable entries. This is primarily to avoid having to read the table in order to determine this number.
10 ipv6DiscardedRoutes	COUNTER	ReadOnly	.1.3.6.1.2.1.55.1.10	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.

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.
Row Description	An interface entry containing objects about a particular IPv6 interface.

ipv6IfTable Indexes:

Name	Type	Access	Description
1 ipv6IfIndex	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.

Other ipv6IfTable Columns:

Name	Type	Access	Description
2 ipv6IfDescr	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.
3 ipv6IfLowerLayer	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 [6]. If this network interface operates over an IPv4 interface, the value of this object refers to an instance of ipAdEntAddr [3]. 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 }.
4 ipv6IfEffectiveMtu	UNSIGNED32	ReadOnly	The size of the largest IPv6 packet which can be sent/received on the interface, specified in octets.
5 ipv6IfReasmMaxSize	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.
6 ipv6IfIdentifier	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.
7 ipv6IfIdentifierLength	INTEGER Legal values: 0 .. 64	ReadWrite	The length of the Interface Identifier in bits.
8 ipv6IfPhysicalAddress	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.
9 ipv6IfAdminStatus	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).
10 ipv6IfOperStatus	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.
11 ipv6IfLastChange	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.

Other ipv6IfStatsTable Columns:

Name	Type	Access	Description
1 ipv6IfStatsInReceives	COUNTER	ReadOnly	The total number of input datagrams received by the interface, including those received in error.
2 ipv6IfStatsInHdrErrors	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.
3 ipv6IfStatsInTooBigErrors	COUNTER	ReadOnly	The number of input datagrams that could not be forwarded because their size exceeded the link MTU of outgoing interface.
4 ipv6IfStatsInNoRoutes	COUNTER	ReadOnly	The number of input datagrams discarded because no route could be found to transmit them to their destination.
5 ipv6IfStatsInAddrErrors	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.
6 ipv6IfStatsInUnknownProtos	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	COUNTER	ReadOnly	The number of input datagrams discarded because datagram frame didn't carry enough data.
8 ipv6IfStatsInDiscards	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.
9 ipv6IfStatsInDelivers	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.
10 ipv6IfStatsOutForwDatagrams	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.
11 ipv6IfStatsOutRequests	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.
12 ipv6IfStatsOutDiscards	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.
13 ipv6IfStatsOutFragOKs	COUNTER	ReadOnly	The number of IPv6 datagrams that have been successfully fragmented at this output interface.
14 ipv6IfStatsOutFragFails	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.
15 ipv6IfStatsOutFragCreates	COUNTER	ReadOnly	The number of output datagram fragments that have been generated as a result of fragmentation at this output interface.
16 ipv6IfStatsReasmReqds	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.
17 ipv6IfStatsReasmOKs	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.
18 ipv6IfStatsReasmFails	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.
19 ipv6IfStatsInMcastPkts	COUNTER	ReadOnly	The number of multicast packets received by the interface
20 ipv6IfStatsOutMcastPkts	COUNTER	ReadOnly	The number of multicast packets transmitted by the interface

When true(1), indicates that this prefix can be used for autonomous address configuration (i.e. can be used to form a local interface address). If false(2), it is not used to autoconfigure a local interface address.
5 ipv6AddrPrefixAdvPreferredLifetime	UNSIGNED32	ReadOnly	It is the length of time in seconds that this prefix will remain preferred, i.e. time until deprecation. A value of 4,294,967,295 represents infinity. The address generated from a deprecated prefix should no longer be used as a source address in new communications, but packets received on such an interface are processed as expected.

Note that 'stateless(1)' refers to an address that was statelessly autoconfigured; 'stateful(2)' refers to a address which was acquired by via a stateful protocol (e.g. DHCPv6, manual configuration).
4 ipv6AddrAnycastFlag	INTEGER TruthValue (ENUM list below)	ReadOnly	Note: this object is based on the TruthValue TEXTUAL-CONVENTION. This object has the value 'true(1)', if this address is an anycast address and the value 'false(2)' otherwise.
5 ipv6AddrStatus	INTEGER Value Label/Meaning 1 preferred 2 deprecated 3 invalid 4 inaccessible 5 unknown	ReadOnly	Address status. The preferred(1) state indicates that this is a valid address that can appear as the destination or source address of a packet. The deprecated(2) state indicates that this is a valid but deprecated address that should no longer be used as a source address in new communications, but packets addressed to such an address are processed as expected. The invalid(3) state indicates that this is not valid address which should not appear as the destination or source address of a packet.

In MIB	IPV6-MIB
Registered at OID	.1.3.6.1.2.1.55.1.11
Table Description	IPv6 Routing table. This table contains an entry for each valid IPv6 unicast route that can be used for packet forwarding determination.
Row Description	A routing entry.

ipv6RouteTable Indexes:

Name	Type	Access	Description
1 ipv6RouteDest	OCTETSTR Legal Lengths: 16 Ipv6Address	NoAccess	Note: this object is based on the Ipv6Address TEXTUAL-CONVENTION. The destination IPv6 address of this route. This object may not take a Multicast address value.
2 ipv6RoutePfxLength	INTEGER Legal values: 0 .. 128	NoAccess	Indicates the prefix length of the destination address.
3 ipv6RouteIndex	UNSIGNED32	NoAccess	The value which uniquely identifies the route among the routes to the same network layer destination. The way this value is chosen is implementation specific but it must be unique for ipv6RouteDest/ipv6RoutePfxLength pair and remain constant for the life of the route.

Other ipv6RouteTable Columns:

Name	Type	Access	Description
4 ipv6RouteIfIndex	INTEGER32 Legal values: 0 .. 2147483647 Ipv6IfIndexOrZero	ReadOnly	Note: this object is based on the Ipv6IfIndexOrZero TEXTUAL-CONVENTION. The index value which uniquely identifies the local interface through which the next hop of this route should be reached. The interface identified by a particular value of this index is the same interface as identified by the same value of ipv6IfIndex. For routes of the discard type this value can be zero.
5 ipv6RouteNextHop	OCTETSTR Legal Lengths: 16 Ipv6Address	ReadOnly	Note: this object is based on the Ipv6Address TEXTUAL-CONVENTION. On remote routes, the address of the next system en route; otherwise, ::0 ('00000000000000000000000000000000'H in ASN.1 string representation).
6 ipv6RouteType	INTEGER Value Label/Meaning 1 other 2 discard 3 local 4 remote	ReadOnly	The type of route. Note that 'local(3)' refers to a route for which the next hop is the final destination; 'remote(4)' refers to a route for which the next hop is not the final destination; 'discard(2)' refers to a route indicating that packets to destinations matching this route are to be discarded (sometimes called black-hole route).
7 ipv6RouteProtocol	INTEGER Value Label/Meaning 1 other 2 local 3 netmgmt 4 ndisc 5 rip 6 ospf 7 bgp 8 idrp 9 igrp	ReadOnly	The routing mechanism via which this route was learned.
8 ipv6RoutePolicy	INTEGER32	ReadOnly	The general set of conditions that would cause the selection of one multipath route (set of next hops for a given destination) is referred to as 'policy'. Unless the mechanism indicated by ipv6RouteProtocol specified otherwise, the policy specifier is the 8-bit Traffic Class field of the IPv6 packet header that is zero extended at the left to a 32-bit value. Protocols defining 'policy' otherwise must either define a set of values which are valid for this object or must implement an integer- instanced policy table for which this object's value acts as an index.
9 ipv6RouteAge	UNSIGNED32	ReadOnly	The number of seconds since this route was last updated or otherwise determined to be correct. Note that no semantics of `too old' can be implied except through knowledge of the routing protocol by which the route was learned.
10 ipv6RouteNextHopRDI	UNSIGNED32	ReadOnly	The Routing Domain ID of the Next Hop. The semantics of this object are determined by the routing-protocol specified in the route's ipv6RouteProtocol value. When this object is unknown or not relevant its value should be set to zero.
11 ipv6RouteMetric	UNSIGNED32	ReadOnly	The routing metric for this route. The semantics of this metric are determined by the routing protocol specified in the route's ipv6RouteProtocol value. When this is unknown or not relevant to the protocol indicated by ipv6RouteProtocol, the object value should be set to its maximum value (4,294,967,295).
12 ipv6RouteWeight	UNSIGNED32	ReadOnly	The system internal weight value for this route. The semantics of this value are determined by the implementation specific rules. Generally, within routes with the same ipv6RoutePolicy value, the lower the weight value the more preferred is the route.
13 ipv6RouteInfo	OBJECTID RowPointer	ReadOnly	Note: this object is based on the RowPointer TEXTUAL-CONVENTION. A reference to MIB definitions specific to the particular routing protocol which is responsible for this route, as determined by the value specified in the route's ipv6RouteProto value. If this information is not present, its value should be set to the OBJECT ID { 0 0 }, which is a syntactically valid object identifier, and any implementation conforming to ASN.1 and the Basic Encoding Rules must be able to generate and recognize this value.
14 ipv6RouteValid	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.

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.
Row Description	Each entry contains one IPv6 address to `physical' address equivalence.

ipv6NetToMediaTable Indexes:

3 ipv6NetToMediaType	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.
4 ipv6IfNetToMediaState	INTEGER Value Label/Meaning 1 reachable 2 stale 3 delay 4 probe 5 invalid 6 unknown	ReadOnly	The Neighbor Unreachability Detection [8] state for the interface when the address mapping in this entry is used.
5 ipv6IfNetToMediaLastUpdated	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.
6 ipv6NetToMediaValid	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.

DEPRECATED OR OBSOLETE OR HISTORIC OBJECTS

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.

Name	Type	Description
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.
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.
PhysAddress	OCTETSTR	Represents media- or physical-level addresses.
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.
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.
Ipv6IfIndex	INTEGER32	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.
Ipv6Address	OCTETSTR	This data type is used to model IPv6 addresses. This is a binary string of 16 octets in network byte-order.
TruthValue	INTEGER Value Label/Meaning 1 true 2 false	Represents a boolean value.
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.
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).
VariablePointer	OBJECTID	A pointer to a specific object instance. For example, sysContact.0 or ifInOctets.3.
