+ OwnerString ::= DisplayString
+ -- This data type is used to model an administratively
+ -- assigned name of the owner of a resource. This
+ -- information is taken from the NVT ASCII character set.
+ -- It is suggested that this name contain one or more
+ -- of the following:
+ -- IP address, management station name, network manager's
+ -- name, location, or phone number.
+ -- In some cases the agent itself will be the owner of
+ -- an entry. In these cases, this string shall be set
+ -- to a string starting with 'monitor'.
+
+
+ --
+ -- SNMP access control is articulated entirely in terms of
+ -- the contents of MIB views; access to a particular SNMP
+ -- object instance depends only upon its presence or
+ -- absence in a particular MIB view and never upon its
+ -- value or the value of related object instances. Thus,
+ -- objects of this type afford resolution of resource
+ -- contention only among cooperating managers; they
+ -- realize no access control function with respect
+ -- to uncooperative parties.
+ --
+ -- By convention, objects with this syntax are declared
+ -- as having
+ --
+ -- SIZE (0..127)

+ EntryStatus ::= INTEGER
+ { valid(1),
+ createRequest(2),
+ underCreation(3),
+ invalid(4)
+ }
+
+ -- The status of a table entry.
+ --
+ -- Setting this object to the value invalid(4) has the
+ -- effect of invalidating the corresponding entry.
+ -- That is, it effectively disassociates 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 currently not in use. Proper
+ -- interpretation of such entries requires examination
+ -- of the relevant EntryStatus object.
+ --
+ -- An existing instance of this object cannot be set to
+ -- createRequest(2). This object may only be set to
+ -- createRequest(2) when this instance is created. When
+ -- this object is created, the agent may wish to create
+ -- supplemental object instances to complete a conceptual
+ -- row in this table. Immediately after completing the
+ -- create operation, the agent must set this object to
+ -- underCreation(3).
+ --
+ -- Entries shall exist in the underCreation(3) state until
+
+
+ -- the management station is finished configuring the
+ -- entry and sets this object to valid(1) or aborts,
+ -- setting this object to invalid(4). If the agent
+ -- determines that an entry has been in the
+ -- underCreation(3) state for an abnormally long time,
+ -- it may decide that the management station has
+ -- crashed. If the agent makes this decision,
+ -- it may set this object to invalid(4) to reclaim the
+ -- entry. A prudent agent will understand that the
+ -- management station may need to wait for human input
+ -- and will allow for that possibility in its
+ -- determination of this abnormally long period.

+ -- The Alarm Group requires the implementation of the Event

+ --
+ -- The Alarm group periodically takes statistical samples from

+ -- that have been configured. The alarm table stores
+ -- configuration entries that each define a variable,
+ -- polling period, and threshold parameters. If a sample is
+ -- found to cross the threshold values, an event is
+ -- generated. Only variables that resolve to an ASN.1
+ -- primitive type of INTEGER (INTEGER, Counter,
+ -- Gauge, or TimeTicks) may be monitored in this way.
+ --
+ -- This function has a hysteresis mechanism to limit the
+ -- generation of events. This mechanism generates one event
+ -- as a threshold is crossed in the appropriate direction.
+ -- No more events are generated for that threshold until the
+ -- opposite threshold is crossed.
+ --
+ -- In the case of a sampling a deltaValue, a probe may

+ -- sum of the latest two samples to the threshold. This
+ -- allows the detection of threshold crossings
+
+
+ -- that span the sampling boundary. Note that this does not
+ -- require any special configuration of the threshold value.
+ -- It is suggested that probes implement this more precise

+ -- The Host Group
+
+ -- Implementation of the Host group is optional.
+ --
+ -- The host group discovers new hosts on the network by
+ -- keeping a list of source and destination MAC Addresses seen
+ -- in good packets. For each of these addresses, the host
+ -- group keeps a set of statistics. The hostControlTable
+ -- controls which interfaces this function is performed on,
+ -- and contains some information about the process. On
+ -- behalf of each hostControlEntry, data is collected on an
+ -- interface and placed both the hostTable and the
+ -- hostTimeTable. If the monitoring device finds itself
+ -- short of resources, it may delete entries as needed. It
+ -- is suggested that the device delete the least recently
+ -- used entries first.
+
+ -- The hostTable contains entries for each address
+ -- discovered on a particular interface. Each entry
+ -- contains statistical data about that host. This table
+ -- is indexed by the MAC address of the host, through
+ -- which a random access may be achieved.
+
+ -- The hostTimeTable contains data in the same format as the
+ -- hostTable, and must contain the same set of hosts, but is
+ -- indexed using hostTimeCreationOrder rather than hostAddress.
+ -- The hostTimeCreationOrder is an integer which reflects
+ -- the relative order in which a particular entry was
+
+
+ -- discovered and thus inserted into the table. As this
+ -- order, and thus index, is among those entries currently
+ -- in the table, the index for a particular entry may change
+ -- if an (earlier) entry is deleted. Thus the association
+ -- between hostTimeCreationOrder and hostTimeEntry may be
+ -- broken at any time.
+
+ -- The hostTimeTable has two important uses. The first is the
+ -- fast download of this potentially large table. Because the
+ -- index of this table runs from 1 to the size of the table,
+ -- inclusive, its values are predictable. This allows very
+ -- efficient packing of variables into SNMP PDU's and allows
+ -- a table transfer to have multiple packets outstanding.
+ -- These benefits increase transfer rates tremendously.
+
+ -- The second use of the hostTimeTable is the efficient
+ -- discovery by the management station of new entries added
+ -- to the table. After the management station has
+ -- downloaded the entire table, it knows that new entries
+ -- will be added immediately after the end of the current
+ -- table. It can thus detect new entries there
+ -- and retrieve them easily.
+
+ -- Because the association between hostTimeCreationOrder and
+ -- hostTimeEntry may be broken at any time, the management
+ -- station must monitor the related hostControlLastDeleteTime
+ -- object. When the management station thus detects a deletion,
+ -- it must assume that any such associations have been broken,
+ -- and invalidate any it has stored locally. This includes
+ -- restarting any download of the hostTimeTable that may have
+ -- been in progress, as well as rediscovering the end of the
+ -- hostTimeTable so that it may detect new entries. If the
+ -- management station does not detect the broken association,
+ -- it may continue to refer to a particular host by its
+ -- creationOrder while unwittingly retrieving the data
+ -- associated with another host entirely. If this happens
+ -- while downloading the host table, the management station
+ -- may fail to download all of the entries in the table.
