The MIB module for managing the collection and storage of
accounting information for connections in a connection-
oriented network such as ATM.    

A list of accounting information selection entries.

Note that additions, modifications and deletions of entries
in this table can occur at any time, but such changes only
take effect on the next occasion when collection begins into
a new file.  Thus, between modification and the next 'swap',
the content of this table does not reflect the current
selection.    

An entry identifying an (subtree, list) tuple used to
select a set of accounting information which is to be
collected.    

An arbitrary integer value which uniquely identifies a
tuple stored in this table.  This value is required to be
the permanent 'handle' for an entry in this table for as
long as that entry exists, including across restarts and
power outages.    

The combination of acctngSelectionSubtree and
acctngSelectionList specifies one (subtree, list) tuple
which is to be collected.    

The combination of acctngSelectionSubtree and
acctngSelectionList specifies one (subtree, list) tuple
which is to be collected.    

An indication of the file into which the accounting
information identified by this entry is to be stored.  If
there is no conceptual row in the acctngFileTable for which
the value of acctngFileIndex has the same value as this
object, then the information selected by this entry is not
collected.    

Indicates the types of connections for which the

information selected by this entry are to be collected.    

The status of this conceptual row.  An agent may refuse to
create new conceptual rows and/or modify existing conceptual
rows, if such creation/modification would cause multiple
rows to have the same values of acctngSelectionSubtree and
acctngSelectionList.

A conceptual row can not have the status of 'active' until
values have been assigned to the acctngSelectionSubtree,
acctngSelectionList and acctngSelectionFile columnar objects
within that row.

An agent must not refuse to change the values of the
acctngSelectionSubtree, acctngSelectionList and
acctngSelectionFile columnar objects within a conceptual row
even while that row's status is 'active'.  Similarly, an
agent must not refuse to destroy an existing conceptual row
while the file referenced by that row's instance of
acctngSelectionFile is in active use, i.e., while the
corresponding instance of acctngFileRowStatus has the value
'active'.  However, such changes only take effect upon the
next occasion when collection begins into a new (version of
the) file.    

A list of files into which accounting information is to be
stored.    

An entry identifying a file into which accounting
information is to be collected.    

A unique value identifying a file into which accounting
data is to be stored.  This value is required to be the
permanent 'handle' for an entry in this table for as long as
that entry exists, including across restarts and power
outages.    

An indication of whether connection data is to be collected

for failed connection attempts when the value of the
corresponding instance of acctngFileCollectMode includes
'onRelease'.  The individual values have the following
meaning:

'soft' - indicates that connection data is to be collected
for failed Soft PVCs/PVPs which originate or terminate at
the relevant interface.

'regular' - indicates that connection data is to be
collected for failed SVCs, including Soft PVCs/PVPs not
originating or terminating at the relevant interface.

This value may be modified at any time.    

The number of seconds between the periodic collections of
accounting data when the value of the corresponding instance
of acctngFileCollectMode includes 'periodically'.  Some
agents may impose restrictions on the range of this
interval.  This value may be modified at any time.    

The minimum age of a connection, as used to determine the
set of connections for which data is to be collected at the
periodic intervals and/or when acctngFileCommand is set to
'collectNow'.  The age of a connection is the elapsed time
since it was last installed.

When the periodic interval expires for a file or when
acctngFileCommand is set to 'collectNow', accounting data is
collected and stored in the file for each connection having
a type matching acctngSelectionType and whose age at that
time is greater than the value of acctngFileMinAge

associated with the file.  This value may be modified at any
time.    

The status of this conceptual row.

This object can not be set to 'active' until a value has
been assigned to the corresponding instance of
acctngFileName.  Collection of data into the file does not
begin until this object has the value 'active' and one or
more (active) instances of acctngSelectionFile refer to it.
If this value is modified after a collection has begun,
collection into this file terminates and a new (or new
version of the) file is immediately made ready for future
collection (as if acctngFileCommand had been set to
'swapToNewFile'), but collection into the new (or new
version of the) file does not begin until the value is
subsequently set back to active.    

The name of the file into which accounting data is to be
stored.  If files are named using suffixes, then the name of
the current file is the concatenation of acctngFileName and
acctngFileNameSuffix.

An agent will respond with an error (e.g., 'wrongValue') to
a management set operation which attempts to modify the

value of this object to the same value as already held by
another instance of acctngFileName.  An agent will also
respond with an error (e.g., 'wrongValue') if the new value
is invalid for use as a file name on the local file system
(e.g., many file systems do not support white space embedded
in file names).

The value of this object can not be modified while the
corresponding instance of acctngFileRowStatus is 'active'.    

The suffix, if any, of the name of a file into which
accounting data is currently being stored.  If suffixes are
not used, then the value of this object is the zero-length
string.  Note that if a separator, such as a period, is used
in appending the suffix to the file name, then that
separator appears as the first character of this value.    

The textual description of the accounting data which will
be stored (on the next occasion) when header information is
stored in the file.  The value of this object may be
modified at any time.    

Possible values are:


idle, cmdInProgress, swapToNewFile, 
collectNow
                

A control object for the collection of accounting data.
When read the value is either 'idle' or 'cmdInProgress'.
Writing a value is only allowed when the current value is
'idle'.  When a value is successfully written, the value
changes to 'cmdInProgress' until completion of the action,
at which time the value reverts to 'idle'.  Actions are
invoked by writing the following values:

'swapToNewFile' - the collection of data into the current
file is terminated, and collection continues into
a new (version of the) file.

'collectNow' - the agent creates and stores a connection
record into the current file for each active
connection having a type matching
acctngSelectionType and an age greater than
acctngFileMinAge.    

The maximum size of the file (including header
information).  When the file of collected data reaches this
size, either the agent automatically swaps to a new version
(i.e., a new value acctngFileNameSuffix) of the file, or new
records are discarded.  Since a file must contain an
integral number of connection records, the actual maximum
size of the file may be just less OR Just greater than the
value of this object.

The value of this object can not be modified while the
corresponding instance of acctngFileRowStatus is 'active'.
The largest value of the maximum file size in some agents
will be less than 2147483647 bytes.    

The current size of the file into which data is currently
being collected, including header information.    

Possible values are:


other, ber
                

An indication of the format in which the accounting data is
to be stored in the file.  If the value is modified, the new
value takes effect after the next 'swap' to a new file.  The
value ber(2) indicates the standard format.    

An indication of when accounting data is to be written into
this file.  Note that in addition to the occasions indicated
by the value of this object, an agent always writes
information on appropriate connections to the file when the
corresponding instance of acctngFileCommand is set to
'collectNow'.

- 'onRelease' - whenever a connection (or possibly,
connection attempt) is terminated, either through
a Release message or through management removal,
information on that connection is written.

- 'periodically' - information on appropriate connections
is written on the expiry of a periodic timer,

This value may be modified at any time.    

Possible values are:


enabled, disabled
                

A control object to indicate the administratively desired
state of the collection of accounting records across all
interfaces.

Modifying the value of acctngAdminStatus to 'disabled' does
not remove or change the current configuration as
represented by the active rows in the acctngSelectionTable,
acctngFileTable and acctngInterfaceTable tables.    

Possible values are:


enabled, disabled
                

A status object to indicate the operational state of the
collection of accounting records across all interfaces.

When the value of acctngAdminStatus is modified to be
'enabled', the value of this object will change to 'enabled'
providing it is possible to begin collecting accounting
records.

When the value of acctngAdminStatus is modified to be
'disabled', the value of this object will change to
'disabled' as soon as the collection of accounting records
has terminated.    

A control object to protect against duplication of control
commands.  Over some transport/network protocols, it is
possible for SNMP messages to get duplicated.  Such
duplication, if it occurred at just the wrong time could
cause serious disruption to the collection and retrieval of
accounting data, e.g., if a SNMP message setting
acctngFileCommand to 'swapToNewFile' were to be duplicated,
a whole file of accounting data could be lost.

To protect against such duplication, a management
application should retrieve the value of this object, and
include in the Set operation needing protection, a variable
binding which sets this object to the retrieved value.    

Possible values are:


swapOnCommand, swapOnFull
                

An indication of the behaviour mode of the agent when a
file becomes full:

'swapOnCommand' - the agent does not automatically swap
to a new file; rather, it discards newly collected
data until a management application subsequently
instructs it to swap to a new file.

'swapOnFull' - the agent terminates collection into the

current file as and when that file becomes full.    

A table controlling the collection of accounting data on
specific interfaces of the switch.    

An entry which controls whether accounting data is to be
collected on an interface.  The types of interfaces which
are represented in this table is implementation-specific.    

Indicates whether the collection of accounting data is
enabled on this interface.    

A percentage of the maximum file size at which a 'nearly-

full' trap is generated.  The value of 0 indicates that no
'nearly-full' trap is to be generated.    

An indication of whether the acctngFileNearlyFull and
acctngFileFull traps are enabled.    

Values are:


acctngFileName, acctngFileMaximumSize, 
acctngControlTrapThreshold, 
acctngFileNameSuffix

An indication that the size of the file into which
accounting information is currently being collected has
exceeded the threshold percentage of its maximum file size.
This notification is generated only at the time of the
transition from not-exceeding to exceeding.    

Values are:


acctngFileName, acctngFileMaximumSize, 
acctngFileNameSuffix

An indication that the size of the file into which
accounting information is currently being collected has
transistioned to its maximum file size.  This notification
is generated (for all values of acctngAgentMode) at the time
of the transition from not-full to full.  If acctngAgentMode
has the value 'swapOnCommand', it is also generated
periodically thereafter until such time as collection of

data is no longer inhibited by the file full condition.    

Values are:


acctngSelectionSubtree, 
acctngSelectionList, 
acctngSelectionFile, 
acctngSelectionType, 
acctngSelectionRowStatus, 
acctngFileName, acctngFileNameSuffix, 
acctngFileDescription, 
acctngFileCommand, 
acctngFileMaximumSize, 
acctngFileCurrentSize, 
acctngFileRowStatus, acctngFileFormat, 
acctngFileCollectMode, 
acctngFileCollectFailedAttempts, 
acctngFileInterval, acctngFileMinAge, 
acctngAdminStatus, acctngOperStatus, 
acctngProtection, acctngAgentMode, 
acctngInterfaceEnable, 
acctngControlTrapThreshold, 
acctngControlTrapEnable

A collection of objects providing control of the basic
collection of accounting data for connection-oriented
networks.    

Values are:


acctngFileNearlyFull, acctngFileFull
                

The notifications of events relating to controlling the
collection of accounting data.    

The compliance statement for switches which implement the
Accounting Control MIB.
