7. Identification of OBJECT instances for use with the SNMP
The names for all object types in the MIB are defined explicitly
either in the Internet-standard MIB or in other documents which
conform to the naming conventions of the SMI. The SMI requires that
conformant management protocols define mechanisms for identifying
individual instances of those object types for a particular network
element.
Each instance of any object type defined in the MIB is identified in
SNMP operations by a unique name called its "variable name." In
general, the name of an SNMP variable is an OBJECT IDENTIFIER of the
form x.y, where x is the name of a non-aggregate object type defined
in the MIB and y is an OBJECT IDENTIFIER fragment that, in a way
specific to the named object type, identifies the desired instance.
This naming strategy admits the fullest exploitation of the semantics
of the powerful SNMP get-next operator, because it assigns names for
related variables so as to be contiguous in the lexicographical
ordering of all variable names known in the MIB.
The type-specific naming of object instances is defined below for a
number of classes of object types. Instances of an object type to
which none of the following naming conventions are applicable are
named by OBJECT IDENTIFIERs of the form x.0, where x is the name of
said object type in the MIB definition.
For example, suppose one wanted to identify an instance of the
variable sysDescr. The object class for sysDescr is:
iso org dod internet mgmt mib system sysDescr
1 3 6 1 2 1 1 1
Hence, the object type, x, would be 1.3.6.1.2.1.1.1 to which is
appended an instance sub-identifier of 0. That is, 1.3.6.1.2.1.1.1.0
identifies the one and only instance of sysDescr.
7.1. ifTable Object Type Names
The name of a subnetwork interface, s, is the OBJECT IDENTIFIER value
of the form i, where i has the value of that instance of the ifIndex
object type associated with s. For each object type, t, for which
the defined name, n, has a prefix of ifEntry, an instance, i, of t is
named by an OBJECT IDENTIFIER of the form n.s, where s is the name of
the subnetwork interface about which i represents information.
For example, suppose one wanted to identify the instance of the
variable ifType associated with interface 2. Accordingly, ifType.2
would identify the desired instance.
7.2. atTable Object Type Names
The name of an address translation entry, x, is an OBJECT IDENTIFIER
of the form s.1.a.b.c.d, such that s is the value of that instance of
the atIfIndex object type associated with x, the subidentifer "1"
signifies the translation of an IP protocol address, and a.b.c.d is
the IP address value (in the familiar "dot" notation) of that
instance of the atNetAddress object type associated with x.
For each object type, t, for which the defined name, n, has a prefix
of atEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of
the form n.y, where y is the name of the address translation entry about which i represents information. For example, suppose one wanted to find the physical address of an entry in the address translation table (ARP cache) associated with an IP address of 89.1.1.42 and interface 3. Accordingly, atPhysAddress.3.1.89.1.1.42 would identify the desired instance. 7.3. ipAddrTable Object Type Names The name of an IP-addressable network element, x, is the OBJECT IDENTIFIER of the form a.b.c.d such that a.b.c.d is the value (in the familiar "dot" notation) of that instance of the ipAdEntAddr object type associated with x. For each object type, t, for which the defined name, n, has a prefix of ipAddrEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of the form n.y, where y is the name of the IP- addressable network element about which i represents information. For example, suppose one wanted to find the network mask of an entry in the IP interface table associated with an IP address of 89.1.1.42. Accordingly, ipAdEntNetMask.89.1.1.42 would identify the desired instance. At the option of the agent, multiple entries for the same IP address may be visible. To realize this, the agent, while required to return a single entry for an IP address, x, of the form n.y, may also return information about other entries for the same IP address using the form n.y.z, where z is a implementation-dependendent small, non- negative integer. It is strongly recommended that the value of z correspond to the value of ipAddrIfIndex for that entry. 7.4. ipRoutingTable Object Type Names The name of an IP route, x, is the OBJECT IDENTIFIER of the form a.b.c.d such that a.b.c.d is the value (in the familiar "dot" notation) of that instance of the ipRouteDest object type associated with x. For each object type, t, for which the defined name, n, has a prefix of ipRoutingEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of the form n.y, where y is the name of the IP route about which i represents information. For example, suppose one wanted to find the next hop of an entry in the IP routing table associated with the destination of 89.1.1.42. Accordingly, ipRouteNextHop.89.1.1.42 would identify the desired
instance. At the option of the agent, multiple routes to the same destination may be visible. To realize this, the agent, while required to return a single entry for an IP route, x, of the form n.y, may also return information about other routes to the same destination using the form n.y.z, where z is a implementation-dependendent small, non-negative integer. 7.5. ipNetToMediaTable Object Type Names The name of a cached IP address, x, is an OBJECT IDENTIFIER of the form s.a.b.c.d, such that s is the value of that instance of the ipNetToMediaIfIndex object type associated with the entry and a.b.c.d is the value (in the familiar "dot" notation) of the ipNetToMediaNetAddress object type associated with x. For each object type, t, for which the defined name, n, has a prefix of ipNetToMediaEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of the form n.y, where y is the name of the cached IP address about which i represents information. For example, suppose one wanted to find the media address of an entry in the address translation table associated with a IP address of 192.52.180.1 and interface 3. Accordingly, ipNetToMediaPhysAddress.3.192.52.180.1 would identify the desired instance. 7.6. tcpConnTable Object Type Names The name of a TCP connection, x, is the OBJECT IDENTIFIER of the form a.b.c.d.e.f.g.h.i.j such that a.b.c.d is the value (in the familiar "dot" notation) of that instance of the tcpConnLocalAddress object type associated with x and such that f.g.h.i is the value (in the familiar "dot" notation) of that instance of the tcpConnRemoteAddress object type associated with x and such that e is the value of that instance of the tcpConnLocalPort object type associated with x and such that j is the value of that instance of the tcpConnRemotePort object type associated with x. For each object type, t, for which the defined name, n, has a prefix of tcpConnEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of the form n.y, where y is the name of the TCP connection about which i represents information. For example, suppose one wanted to find the state of a TCP connection between the local address of 89.1.1.42 on TCP port 21 and the remote address of 10.0.0.51 on TCP port 2059. Accordingly,
tcpConnState.89.1.1.42.21.10.0.0.51.2059 would identify the desired instance. 7.7. udpTable Object Type Names The name of a UDP listener, x, is the OBJECT IDENTIFIER of the form a.b.c.d.e. such that a.b.c.d is the value (in the familiar "dot" notation) of that instance of the udpLocalAddress object type associated with x and such that e is the value of that instance of the udpLocalPort object type associated with x. For each object type, t, for which the defined name, n, has a prefix of udpEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of the form n.y, where y is the name of the UDP listener about which i represents information. For example, suppose one wanted to determine if a UDP listener was present at the local address of 89.1.1.42 on UDP port 21. Accordingly, a successful retrieval of either udpLocalAddress.89.1.1.42.21 or udpLocalPort.89.1.1.42.21 would indicate this. 7.8. egpNeighTable Object Type Names The name of an EGP neighbor, x, is the OBJECT IDENTIFIER of the form a.b.c.d such that a.b.c.d is the value (in the familiar "dot" notation) of that instance of the egpNeighAddr object type associated with x. For each object type, t, for which the defined name, n, has a prefix of egpNeighEntry, an instance, i, of t is named by an OBJECT IDENTIFIER of the form n.y, where y is the name of the EGP neighbor about which i represents information. For example, suppose one wanted to find the neighbor state for the IP address of 89.1.1.42. Accordingly, egpNeighState.89.1.1.42 would identify the desired instance. 8.
