Table ipAddressPrefixTable

Table Name	ipAddressPrefixTable
In MIB	IP-MIB
Registered at OID	.1.3.6.1.2.1.4.32
Table Description	This table allows the user to determine the source of an IP address or set of IP addresses, and allows other tables to share the information via pointer rather than by copying. For example, when the node configures both a unicast and anycast address for a prefix, the ipAddressPrefix objects for those addresses will point to a single row in this table. This table primarily provides support for IPv6 prefixes, and several of the objects are less meaningful for IPv4. The table continues to allow IPv4 addresses to allow future flexibility. In order to promote a common configuration, this document includes suggestions for default values for IPv4 prefixes. Each of these values may be overridden if an object is meaningful to the node. All prefixes used by this entity should be included in this table independent of how the entity learned the prefix. (This table isn't limited to prefixes learned from router advertisements.)
Row Description	An entry in the ipAddressPrefixTable.

ipAddressPrefixTable Indexes:

Name	Type	Access	Description
1 ipAddressPrefixIfIndex	INTEGER32 Legal values: 1 .. 2147483647 InterfaceIndex	NoAccess	Note: this object is based on the InterfaceIndex TEXTUAL-CONVENTION. The index value that uniquely identifies the interface on which this prefix is configured. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.
2 ipAddressPrefixType	INTEGER InetAddressType (ENUM list below)	NoAccess	Note: this object is based on the InetAddressType TEXTUAL-CONVENTION. The address type of ipAddressPrefix.
3 ipAddressPrefixPrefix	OCTETSTR Legal Lengths: 0 .. 255 InetAddress	NoAccess	Note: this object is based on the InetAddress TEXTUAL-CONVENTION. The address prefix. The address type of this object is specified in ipAddressPrefixType. The length of this object is the standard length for objects of that type (4 or 16 bytes). Any bits after ipAddressPrefixLength must be zero. Implementors need to be aware that, if the size of ipAddressPrefixPrefix exceeds 114 octets, then OIDS of instances of columns in this row will have more than 128 sub-identifiers and cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3.
4 ipAddressPrefixLength	UNSIGNED32 Legal values: 0 .. 2040 InetAddressPrefixLength	NoAccess	Note: this object is based on the InetAddressPrefixLength TEXTUAL-CONVENTION. The prefix length associated with this prefix. The value 0 has no special meaning for this object. It simply refers to address '::/0'.

8 ipAddressPrefixAdvPreferredLifetime	UNSIGNED32	ReadOnly	The remaining length of time, in seconds, that this prefix will continue to be 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. The default for IPv4 prefixes is 4,294,967,295 (infinity). Also see Reference: For IPv6 RFC 2461, especially sections 2 and 4.6.2 and RFC 2462
9 ipAddressPrefixAdvValidLifetime	UNSIGNED32	ReadOnly	The remaining length of time, in seconds, that this prefix will continue to be valid, i.e., time until invalidation. A value of 4,294,967,295 represents infinity. The address generated from an invalidated prefix should not appear as the destination or source address of a packet.

Table ipAddressTable

Table Name	ipAddressTable
In MIB	IP-MIB
Registered at OID	.1.3.6.1.2.1.4.34
Table Description	This table contains addressing information relevant to the entity's interfaces. This table does not contain multicast address information. Tables for such information should be contained in multicast specific MIBs, such as RFC 3019. While this table is writable, the user will note that several objects, such as ipAddressOrigin, are not. The intention in allowing a user to write to this table is to allow them to add or remove any entry that isn't permanent. The user should be allowed to modify objects and entries when that would not cause inconsistencies within the table. Allowing write access to objects, such as ipAddressOrigin, could allow a user to insert an entry and then label it incorrectly. Note well: When including IPv6 link-local addresses in this table, the entry must use an InetAddressType of 'ipv6z' in order to differentiate between the possible interfaces.
Row Description	An address mapping for a particular interface.

ipAddressTable Indexes:

Name	Type	Access	Description
1 ipAddressAddrType	INTEGER InetAddressType (ENUM list below)	NoAccess	Note: this object is based on the InetAddressType TEXTUAL-CONVENTION. The address type of ipAddressAddr.

9 ipAddressLastChanged	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.
10 ipAddressRowStatus	INTEGER RowStatus (ENUM list below)	Create	Note: this object is based on the RowStatus TEXTUAL-CONVENTION. The status of this conceptual row. The RowStatus TC requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified. The value of this object has no effect on whether other objects in this conceptual row can be modified. A conceptual row can not be made active until the ipAddressIfIndex has been set to a valid index.
11 ipAddressStorageType	INTEGER StorageType (ENUM list below)	Create	Note: this object is based on the StorageType TEXTUAL-CONVENTION. The storage type for this conceptual row. If this object has a value of 'permanent', then no other objects are required to be able to be modified.

Table ipNetToPhysicalTable

Table Name	ipNetToPhysicalTable
In MIB	IP-MIB
Registered at OID	.1.3.6.1.2.1.4.35
Table Description	The IP Address Translation table used for mapping from IP addresses to physical addresses. The Address Translation tables contain the IP address to 'physical' address equivalences. Some interfaces do not use translation tables for determining address equivalences (e.g., DDN-X.25 has an algorithmic method); if all interfaces are of this type, then the Address Translation table is empty, i.e., has zero entries. While many protocols may be used to populate this table, ARP and Neighbor Discovery are the most likely options. Also see Reference: RFC 826 and RFC 2461
Row Description	Each entry contains one IP address to `physical' address equivalence.

ipNetToPhysicalTable Indexes:

Name	Type	Access	Description
1 ipNetToPhysicalIfIndex	INTEGER32 Legal values: 1 .. 2147483647 InterfaceIndex	NoAccess	Note: this object is based on the InterfaceIndex TEXTUAL-CONVENTION. The index value that uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.
2 ipNetToPhysicalNetAddressType	INTEGER InetAddressType (ENUM list below)	NoAccess	Note: this object is based on the InetAddressType TEXTUAL-CONVENTION. The type of ipNetToPhysicalNetAddress.
3 ipNetToPhysicalNetAddress	OCTETSTR Legal Lengths: 0 .. 255 InetAddress	NoAccess	Note: this object is based on the InetAddress TEXTUAL-CONVENTION. The IP Address corresponding to the media-dependent `physical' address. The address type of this object is specified in ipNetToPhysicalAddressType. Implementors need to be aware that if the size of ipNetToPhysicalNetAddress exceeds 115 octets, then OIDS of instances of columns in this row will have more than 128 sub-identifiers and cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3.

Other ipNetToPhysicalTable Columns:

Name	Type	Access	Description
4 ipNetToPhysicalPhysAddress	OCTETSTR Legal Lengths: 0 .. 65535 PhysAddress	Create	Note: this object is based on the PhysAddress TEXTUAL-CONVENTION. The media-dependent `physical' address. As the entries in this table are typically not persistent when this object is written the entity SHOULD NOT save the change to non-volatile storage.
5 ipNetToPhysicalLastUpdated	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 ipNetToPhysicalType	INTEGER Value Label/Meaning 1 other 2 invalid 3 dynamic 4 static 5 local	Create	The type of mapping. Setting this object to the value invalid(2) has the effect of invalidating the corresponding entry in the ipNetToPhysicalTable. That is, it effectively dis- associates 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 ipNetToPhysicalType object. The 'dynamic(3)' type indicates that the IP address to physical addresses mapping has been dynamically resolved using e.g., IPv4 ARP or the IPv6 Neighbor Discovery protocol. The 'static(4)' type indicates that the mapping has been statically configured. Both of these refer to entries that provide mappings for other entities addresses. The 'local(5)' type indicates that the mapping is provided for an entity's own interface address. As the entries in this table are typically not persistent when this object is written the entity SHOULD NOT save the change to non-volatile storage.
7 ipNetToPhysicalState	INTEGER Value Label/Meaning 1 reachable 2 stale 3 delay 4 probe 5 invalid 6 unknown 7 incomplete	ReadOnly	The Neighbor Unreachability Detection state for the interface when the address mapping in this entry is used. If Neighbor Unreachability Detection is not in use (e.g. for IPv4), this object is always unknown(6). Also see Reference: RFC 2461
8 ipNetToPhysicalRowStatus	INTEGER RowStatus (ENUM list below)	Create	Note: this object is based on the RowStatus TEXTUAL-CONVENTION. The status of this conceptual row. The RowStatus TC requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified. The value of this object has no effect on whether other objects in this conceptual row can be modified. A conceptual row can not be made active until the ipNetToPhysicalPhysAddress object has been set. Note that if the ipNetToPhysicalType is set to 'invalid', the managed node may delete the entry independent of the state of this object.

In MIB	IP-MIB
Registered at OID	.1.3.6.1.2.1.4.37
Table Description	The table used to describe the default routers known to this entity.
Row Description	Each entry contains information about a default router known to this entity.

ipDefaultRouterTable Indexes:

Name	Type	Access	Description
1 ipDefaultRouterAddressType	INTEGER InetAddressType (ENUM list below)	NoAccess	Note: this object is based on the InetAddressType TEXTUAL-CONVENTION. The address type for this row.
2 ipDefaultRouterAddress	OCTETSTR Legal Lengths: 0 .. 255 InetAddress	NoAccess	Note: this object is based on the InetAddress TEXTUAL-CONVENTION. The IP address of the default router represented by this row. The address type of this object is specified in ipDefaultRouterAddressType. Implementers need to be aware that if the size of ipDefaultRouterAddress exceeds 115 octets, then OIDS of instances of columns in this row will have more than 128 sub-identifiers and cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3.
3 ipDefaultRouterIfIndex	INTEGER32 Legal values: 1 .. 2147483647 InterfaceIndex	NoAccess	Note: this object is based on the InterfaceIndex TEXTUAL-CONVENTION. The index value that uniquely identifies the interface by which the router can be reached. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.

Other ipDefaultRouterTable Columns:

Name	Type	Access	Description
4 ipDefaultRouterLifetime	UNSIGNED32 Legal values: 0 .. 65535	ReadOnly	The remaining length of time, in seconds, that this router will continue to be useful as a default router. A value of zero indicates that it is no longer useful as a default router. It is left to the implementer of the MIB as to whether a router with a lifetime of zero is removed from the list. For IPv6, this value should be extracted from the router advertisement messages. Also see Reference: For IPv6 RFC 2462 sections 4.2 and 6.3.4
5 ipDefaultRouterPreference	INTEGER Value Label/Meaning -2 reserved -1 low 0 medium 1 high	ReadOnly	An indication of preference given to this router as a default router as described in he Default Router Preferences document. Treating the value as a 2 bit signed integer allows for simple arithmetic comparisons. For IPv4 routers or IPv6 routers that are not using the updated router advertisement format, this object is set to medium (0). Also see Reference: RFC 4291, section 2.1

Table ipv6RouterAdvertTable

Table Name	ipv6RouterAdvertTable
In MIB	IP-MIB
Registered at OID	.1.3.6.1.2.1.4.39
Table Description	The table containing information used to construct router advertisements.
Row Description	An entry containing information used to construct router advertisements. Information in this table is persistent, and when this object is written, the entity SHOULD save the change to non-volatile storage.

ipv6RouterAdvertTable Indexes:

Name	Type	Access	Description
1 ipv6RouterAdvertIfIndex	INTEGER32 Legal values: 1 .. 2147483647 InterfaceIndex	NoAccess	Note: this object is based on the InterfaceIndex TEXTUAL-CONVENTION. The index value that uniquely identifies the interface on which router advertisements constructed with this information will be transmitted. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.

Other ipv6RouterAdvertTable Columns:

Name	Type	Access	Description
2 ipv6RouterAdvertSendAdverts	INTEGER TruthValue (ENUM list below)	Create	Note: this object is based on the TruthValue TEXTUAL-CONVENTION. A flag indicating whether the router sends periodic router advertisements and responds to router solicitations on this interface. Also see Reference: RFC 2461 Section 6.2.1
3 ipv6RouterAdvertMaxInterval	UNSIGNED32 Legal values: 4 .. 1800	Create	The maximum time allowed between sending unsolicited router advertisements from this interface. Also see Reference: RFC 2461 Section 6.2.1
4 ipv6RouterAdvertMinInterval	UNSIGNED32 Legal values: 3 .. 1350	Create	The minimum time allowed between sending unsolicited router advertisements from this interface. The default is 0.33 * ipv6RouterAdvertMaxInterval, however, in the case of a low value for ipv6RouterAdvertMaxInterval, the minimum value for this object is restricted to 3. Also see Reference: RFC 2461 Section 6.2.1
5 ipv6RouterAdvertManagedFlag	INTEGER TruthValue (ENUM list below)	Create	Note: this object is based on the TruthValue TEXTUAL-CONVENTION. The true/false value to be placed into the 'managed address configuration' flag field in router advertisements sent from this interface. Also see Reference: RFC 2461 Section 6.2.1
6 ipv6RouterAdvertOtherConfigFlag	INTEGER TruthValue (ENUM list below)	Create	Note: this object is based on the TruthValue TEXTUAL-CONVENTION. The true/false value to be placed into the 'other stateful configuration' flag field in router advertisements sent from this interface. Also see Reference: RFC 2461 Section 6.2.1
7 ipv6RouterAdvertLinkMTU	UNSIGNED32	Create	The value to be placed in MTU options sent by the router on this interface. A value of zero indicates that no MTU options are sent. Also see Reference: RFC 2461 Section 6.2.1
8 ipv6RouterAdvertReachableTime	UNSIGNED32 Legal values: 0 .. 3600000	Create	The value to be placed in the reachable time field in router advertisement messages sent from this interface. A value of zero in the router advertisement indicates that the advertisement isn't specifying a value for reachable time. Also see Reference: RFC 2461 Section 6.2.1
9 ipv6RouterAdvertRetransmitTime	UNSIGNED32	Create	The value to be placed in the retransmit timer field in router advertisements sent from this interface. A value of zero in the router advertisement indicates that the advertisement isn't specifying a value for retrans time. Also see Reference: RFC 2461 Section 6.2.1
10 ipv6RouterAdvertCurHopLimit	UNSIGNED32 Legal values: 0 .. 255	Create	The default value to be placed in the current hop limit field in router advertisements sent from this interface. The value should be set to the current diameter of the Internet. A value of zero in the router advertisement indicates that the advertisement isn't specifying a value for curHopLimit. The default should be set to the value specified in the IANA web pages (www.iana.org) at the time of implementation. Also see Reference: RFC 2461 Section 6.2.1
11 ipv6RouterAdvertDefaultLifetime	UNSIGNED32 Legal values: 0 , 4 .. 9000	Create	The value to be placed in the router lifetime field of router advertisements sent from this interface. This value MUST be either 0 or between ipv6RouterAdvertMaxInterval and 9000 seconds. A value of zero indicates that the router is not to be used as a default router. The default is 3 * ipv6RouterAdvertMaxInterval. Also see Reference: RFC 2461 Section 6.2.1
12 ipv6RouterAdvertRowStatus	INTEGER RowStatus (ENUM list below)	Create	Note: this object is based on the RowStatus TEXTUAL-CONVENTION. The status of this conceptual row. As all objects in this conceptual row have default values, a row can be created and made active by setting this object appropriately. The RowStatus TC requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified. The value of this object has no effect on whether other objects in this conceptual row can be modified.
