-
- -- more of the following: IP address, management station
- -- name, network manager's name, location, or phone
- -- number.

- -- 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.

- { valid(1),

- -- 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 with default values
- -- to complete a conceptual row in this table. Because
-
-
- -- the creation of these default objects is entirely at
- -- the option of the agent, the manager must not assume
- -- that any will be created, but may make use of any that
- -- are created. Immediately after completing the create
- -- operation, the agent must set this object to
- -- underCreation(3).
- --
- -- When in the underCreation(3) state, an entry is
- -- allowed to exist in a possibly incomplete, possibly
- -- inconsistent state, usually to allow it to be
- -- modified in mutiple PDUs. When in this state, an
- -- entry is not fully active. 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.
- --
- -- An entry in the valid(1) state is fully configured and
- -- consistent and fully represents the configuration or
- -- operation such a row is intended to represent. For
- -- example, it could be a statistical function that is
- -- configured and active, or a filter that is available
- -- in the list of filters processed by the packet capture
- -- process.
- --
- -- A manager is restricted to changing the state of an
- -- entry in the following ways:
- --
- -- create under
- -- To: valid Request Creation invalid
- -- From:
- -- valid OK NO OK OK
- -- createRequest N/A N/A N/A N/A
- -- underCreation OK NO OK OK
- -- invalid NO NO NO OK
- -- nonExistent NO OK NO OK
- --
- -- In the table above, it is not applicable to move the
- -- state from the createRequest state to any other
-
-
- -- state because the manager will never find the
- -- variable in that state. The nonExistent state is
- -- not a value of the enumeration, rather it means that
- -- the entryStatus variable does not exist at all.
- --
- -- An agent may allow an entryStatus variable to change
- -- state in additional ways, so long as the semantics
- -- of the states are followed. This allowance is made
- -- to ease the implementation of the agent and is made
- -- despite the fact that managers should never
- -- excercise these additional state transitions.

- -- 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 in 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 the 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.

+
+ REVISION "199502010000Z" -- 1 Feb, 1995
+ DESCRIPTION
+ "Bug fixes, clarifications and minor changes based on
+ implementation experience, published as RFC1757 [18].
+
+ Two changes were made to object definitions:
+
+ 1) A new status bit has been defined for the
+ captureBufferPacketStatus object, indicating that the
+ packet order within the capture buffer may not be identical to
+ the packet order as received off the wire. This bit may only
+ be used for packets transmitted by the probe. Older NMS
+ applications can safely ignore this status bit, which might be
+ used by newer agents.
+
+ 2) The packetMatch trap has been removed. This trap was never
+ actually 'approved' and was not added to this document along
+ with the risingAlarm and fallingAlarm traps. The packetMatch
+ trap could not be throttled, which could cause disruption of
+ normal network traffic under some circumstances. An NMS should
+ configure a risingAlarm threshold on the appropriate
+ channelMatches instance if a trap is desired for a packetMatch
+ event. Note that logging of packetMatch events is still
+ supported--only trap generation for such events has been
+ removed.
+
+ In addition, several clarifications to individual object
+ definitions have been added to assist agent and NMS
+ implementors:
+
+ - global definition of 'good packets' and 'bad packets'
+
+ - more detailed text governing conceptual row creation and
+ modification
+
+ - instructions for probes relating to interface changes and
+ disruptions
+
+ - clarification of some ethernet counter definitions
+
+ - recommended formula for calculating network utilization
+
+ - clarification of channel and captureBuffer behavior for some
+ unusual conditions
+
+ - examples of proper instance naming for each table"

+
+EntryStatus ::= TEXTUAL-CONVENTION
+ STATUS current
+ DESCRIPTION
+ "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 with default values
+ to complete a conceptual row in this table. Because the
+ creation of these default objects is entirely at the option
+ of the agent, the manager must not assume that any will be
+ created, but may make use of any that are created.
+ Immediately after completing the create operation, the agent
+ must set this object to underCreation(3).
+
+ When in the underCreation(3) state, an entry is allowed to
+ exist in a possibly incomplete, possibly inconsistent state,
+ usually to allow it to be modified in multiple PDUs. When in
+ this state, an entry is not fully active.
+ 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.
+
+ An entry in the valid(1) state is fully configured and
+ consistent and fully represents the configuration or
+ operation such a row is intended to represent. For
+ example, it could be a statistical function that is
+ configured and active, or a filter that is available
+ in the list of filters processed by the packet capture
+ process.
+
+ A manager is restricted to changing the state of an entry in
+ the following ways:
+
+ To: valid createRequest underCreation invalid
+ From:
+ valid OK NO OK OK
+ createRequest N/A N/A N/A N/A
+ underCreation OK NO OK OK
+ invalid NO NO NO OK
+ nonExistent NO OK NO OK
+
+ In the table above, it is not applicable to move the state
+ from the createRequest state to any other state because the
+ manager will never find the variable in that state. The
+ nonExistent state is not a value of the enumeration, rather
+ it means that the entryStatus variable does not exist at all.
+
+ An agent may allow an entryStatus variable to change state in
+ additional ways, so long as the semantics of the states are
+ followed. This allowance is made to ease the implementation of
+ the agent and is made despite the fact that managers should
+ never exercise these additional state transitions."

+
+ Probe location plays a much smaller role when considering

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

+-- entries that each define a variable, polling period, and

+--
+-- This function has a hysteresis mechanism to limit the generation

+-- 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 implement

+-- The host group discovers new hosts on the network by

+-- 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
+-- in 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
+-- the 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.

+-- The Filter group allows packets to be captured with an

+-- event stream or "channel" is formed by the packets
+-- that match the filter expression.
+--
+-- This filter mechanism allows the creation of an arbitrary

+-- Within a filter, any bits checked in the data and status are
+-- AND'ed with respect to other bits in the same filter. The
+-- NotMask also allows for checking for inequality. Finally,
+-- the channelAcceptType object allows for inversion of the
+-- whole equation.
+--
+-- If a management station wishes to receive a trap to alert it

+-- download, it is recommended that it set up an alarm entry that

+-- The Event Group
+
+-- Implementation of the Event group is optional.

+--
+-- The Event group controls the generation and notification
+-- of events from this device. Each entry in the eventTable
+-- describes the parameters of the event that can be triggered.
+-- Each event entry is fired by an associated condition located
+-- elsewhere in the MIB. An event entry may also be associated
+-- with a function elsewhere in the MIB that will be executed
+-- when the event is generated. For example, a channel may
+-- be turned on or off by the firing of an event.
+--
+-- Each eventEntry may optionally specify that a log entry
+-- be created on its behalf whenever the event occurs.
+-- Each entry may also specify that notification should
+-- occur by way of SNMP trap messages. In this case, the
+-- community for the trap message is given in the associated
+-- eventCommunity object. The enterprise and specific trap
+-- fields of the trap are determined by the condition that
+-- triggered the event. Two traps are defined: risingAlarm and
+-- fallingAlarm. If the eventTable is triggered by a condition
+-- specified elsewhere, the enterprise and specific trap fields
+-- must be specified for traps generated for that condition.
