-- 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

"This object identifies the source of the data that

|
|
In order to identify a particular interface, this

object shall identify the instance of the ifIndex
|
|
object, defined in RFC 1213 and RFC 1573 [4,6], for
|
|
the desired interface. For example, if an entry

|
were to receive data from interface #1, this object
|
|
would be set to ifIndex.1.
|
|
|
|
The statistics in this group reflect all packets
|
|
on the local network segment attached to the
|
|
identified interface.
|
|
|
|
An agent may or may not be able to tell if
|
|
fundamental changes to the media of the interface
|
|
have occurred and necessitate an invalidation of
|
|
this entry. For example, a hot-pluggable ethernet
|
|
card could be pulled out and replaced by a
|
|
token-ring card. In such a case, if the agent has
|
|
such knowledge of the change, it is recommended that
|
|
it invalidate this entry.

are used to calculate the Utilization as follows:

Pkts * (9.6 + 6.4) + (Octets * .8)

Utilization = -------------------------------------

Interval * 10,000

DESCRIPTION
|
|
"The best estimate of the total number of collisions
|
|
on this Ethernet segment.
|
|
|
|
The value returned will depend on the location of
|
|
the RMON probe. Section 8.2.1.3 (10BASE-5) and
|
|
section 10.3.1.3 (10BASE-2) of IEEE standard 802.3
|
|
states that a station must detect a collision, in
|
|
the receive mode, if three or more stations are
|
|
transmitting simultaneously. A repeater port must
|
|
detect a collision when two or more stations are
|
|
transmitting simultaneously. Thus a probe placed on
|
|
a repeater port could record more collisions than a
|
|
probe connected to a station on the same segment
|
|
would.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Probe location plays a much smaller role when
|
|
considering 10BASE-T. 14.2.1.4 (10BASE-T) of IEEE
|
|
standard 802.3 defines a collision as the
|
|
simultaneous presence of signals on the DO and RD
|
|
circuits (transmitting and receiving at the same
|
|
time). A 10BASE-T station can only detect
|
|
collisions when it is transmitting. Thus probes
|
|
placed on a station and a repeater, should report
|
|
the same number of collisions.
|
|
|
|
Note also that an RMON probe inside a repeater
|
|
should ideally report collisions between the
|
|
repeater and one or more other hosts (transmit
|
|
collisions as defined by IEEE 802.3k) plus receiver
|
|
collisions observed on any coax segments to which
|
|
the repeater is connected."

Because the counters in a bucket may overflow at their

"The best estimate of the total number of collisions

on this Ethernet segment during this sampling

|

The value returned will depend on the location of

the RMON probe. Section 8.2.1.3 (10BASE-5) and
|
|
section 10.3.1.3 (10BASE-2) of IEEE standard 802.3
|
|
states that a station must detect a collision, in
|
|
the receive mode, if three or more stations are
|
|
transmitting simultaneously. A repeater port must
|
|
detect a collision when two or more stations are
|
|
transmitting simultaneously. Thus a probe placed on
|
|
a repeater port could record more collisions than a
|
|
probe connected to a station on the same segment
|
|
would.
|
|
|
|
Probe location plays a much smaller role when
|
|
considering 10BASE-T. 14.2.1.4 (10BASE-T) of IEEE
|
|
standard 802.3 defines a collision as the
|
|
simultaneous presence of signals on the DO and RD
|
|
circuits (transmitting and receiving at the same
|
|
time). A 10BASE-T station can only detect
|
|
collisions when it is transmitting. Thus probes
|
|
|
|
|
|
|
|
|
|
|
|
placed on a station and a repeater, should report
|
|
the same number of collisions.
|
|
|
|
Note also that an RMON probe inside a repeater
|
|
should ideally report collisions between the
|
|
repeater and one or more other hosts (transmit
|
|
collisions as defined by IEEE 802.3k) plus receiver
|

collisions observed on any coax segments to which

-- 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.

"This object identifies the source of

the data from which this entry creates a traffic
|

|
device. In order to identify a particular
|
|
interface, this object shall identify the instance
|
|
of the ifIndex object, defined in RFC 1213 and RFC
|

1573 [4,6], for the desired interface. For example,

if an entry were to receive data from interface #1,

this object would be set to ifIndex.1.

-- Implementation of the Filter group is optional.

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

-- This filter mechanism allows the creation of an arbitrary

two rules are then applied to every packet:

(1) For each relevant bit from the packet status

set to zero, if the bit from the packet status is

packet's status.
|

The value of the packet status is a sum. This sum

initially takes the value zero. Then, for each

error, E, that has been discovered in this packet,
|
|
2 raised to a value representing E is added to the

sum. The errors and the bits that represent them are

dependent on the media type of the interface that

this channel is receiving packets from.
|
|
|
|
The errors defined for a packet captured off of an

|
Ethernet interface are as follows:
|
|

|
bit # Error
|
|
0 Packet is longer than 1518 octets
|
|
1 Packet is shorter than 64 octets
|
|
2 Packet experienced a CRC or Alignment
|

error

For example, an Ethernet fragment would have a

value of 6 (2^1 + 2^2).

The value of this object is defined in the same way as

initially takes the value zero. Then, for each

|
error, E, that has been discovered in this packet,
|
|
2 raised to a value representing E is added to the
|
|
sum.
|
|
|
|
The errors defined for a packet captured off of an
|
|
Ethernet interface are as follows:
|
|
|
|
bit # Error
|
|
0 Packet is longer than 1518 octets
|
|
1 Packet is shorter than 64 octets
|
|
2 Packet experienced a CRC or Alignment

|
error
|
|
3 First packet in this capture buffer after
|
|
it was detected that some packets were
|
|
not processed correctly.
|
|
4 Packet's order in buffer is only
|
|
approximate (May only be set for packets
|
|
sent from the probe)
|
|
|
|
For example, an Ethernet fragment would have a
|
|
value of 6 (2^1 + 2^2).

-- Each eventEntry may optionally specify that a log entry
