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

Top       Page 127 
   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

Top       Page 128 
   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

Top       Page 129 
   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,

Top       Page 130 
   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.
