ZeroBasedCounter32 ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This TC describes an object which counts events with the
following semantics: objects of this type will be set to
zero(0) on creation and will thereafter count appropriate
events, wrapping back to zero(0) when the value 2^32 is
reached.
Provided that an application discovers the new object within
the minimum time to wrap it can use the initial value as a
delta since it last polled the table of which this object is
part. It is important for a management station to be aware of
this minimum time and the actual time between polls, and to
discard data if the actual time is too long or there is no
defined minimum time.
Typically this TC is used in tables where the INDEX space is
constantly changing and/or the TimeFilter mechanism is in use."
SYNTAX Gauge32
LastCreateTime ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This TC describes an object that stores the last time its
entry was created.
This can be used for polling applications to determine that an
entry has been deleted and re-created between polls, causing
an otherwise undetectable discontinuity in the data."
SYNTAX TimeStamp
TimeFilter ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"To be used for the index to a table. Allows an application
to download only those rows changed since a particular time.
A row is considered changed if the value of any object in the
row changes or if the row is created or deleted.
When sysUpTime is equal to zero, this table shall be empty.
One entry exists for each past value of sysUpTime, except that
the whole table is purged should sysUpTime wrap.
As this basic row is updated new conceptual rows are created
(which still share the now updated object values with all
other instances). The number of instances which are created
is determined by the value of sysUpTime at which the basic row
was last updated. One instance will exist for each value of
sysUpTime at the last update time for the row. A new
timeMark instance is created for each new sysUpTime value.
Each new conceptual row will be associated with the timeMark
instance which was created at the value of sysUpTime with
which the conceptual row is to be associated.
By definition all conceptual rows were updated at or after
time zero and so at least one conceptual row (associated with
timeMark.0) must exist for each underlying (basic) row.
See the appendix for further discussion of this variable.
Consider the following fooTable:
fooTable ...
INDEX { fooTimeMark, fooIndex }
FooEntry {
fooTimeMark TimeFilter
fooIndex INTEGER,
fooCounts Counter
}
Should there be two basic rows in this table (fooIndex == 1,
fooIndex == 2) and row 1 was updated most recently at time 6,
while row 2 was updated most recently at time 8, and both rows
had been updated on several earlier occasions such that the
current values were 5 and 9 respectively then the following
fooCounts instances would exist.
fooCounts.0.1 5
fooCounts.0.2 9
fooCounts.1.1 5
fooCounts.1.2 9
fooCounts.2.1 5
fooCounts.2.2 9
fooCounts.3.1 5
fooCounts.3.2 9
fooCounts.4.1 5
fooCounts.4.2 9
fooCounts.5.1 5
fooCounts.5.2 9
fooCounts.6.1 5
fooCounts.6.2 9
fooCounts.7.2 9 -- note that row 1 doesn't exist for
fooCounts.8.2 9 -- times 7 and 8"

different network layer, transport layer, and higher-layer
protocols. The agent should boot up with this table
preconfigured with those protocols that it knows about and

protocolDirID OBJECT-TYPE
SYNTAX OCTET STRING
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A unique identifier for a particular protocol. Standard
identifiers will be defined in a manner such that they
can often be used as specifications for new protocols - i.e.
a tree-structured assignment mechanism that matches the
protocol encapsulation `tree' and which has algorithmic
assignment mechanisms for certain subtrees. See RFC XXX for
more details.
Despite the algorithmic mechanism, the probe will only place
entries in here for those protocols it chooses to collect. In
other words, it need not populate this table with all of the
possible ethernet protocol types, nor need it create them on
the fly when it sees them. Whether or not it does these
things is a matter of product definition (cost/benefit,
usability), and is up to the designer of the product.
If an entry is written to this table with a protocolDirID that
the agent doesn't understand, either directly or
algorithmically, the SET request will be rejected with an
inconsistentName or badValue (for SNMPv1) error."

protocolDirParameters OBJECT-TYPE
SYNTAX OCTET STRING
MAX-ACCESS not-accessible

DESCRIPTION
"A set of parameters for the associated protocolDirID.
See the associated RMON2 Protocol Identifiers document
for a description of the possible parameters. There
will be one octet in this string for each sub-identifier in
the protocolDirID, and the parameters will appear here in the
same order as the associated sub-identifiers appear in the
protocolDirID.
Every node in the protocolDirID tree has a different, optional
set of parameters defined (that is, the definition of
parameters for a node is optional). The proper parameter
value for each node is included in this string. Note that the
inclusion of a parameter value in this string for each node is
not optional - what is optional is that a node may have no
parameters defined, in which case the parameter field for that
node will be zero."

DESCRIPTION
"The locally arbitrary, but unique identifier associated
with this protocolDir entry.
The value for each supported protocol must remain constant at
least from one re-initialization of the entity's network
management system to the next re-initialization, except that
if a protocol is deleted and re-created, it must be re-created
with a new value that has not been used since the last
re-initialization.
The specific value is meaningful only within a given SNMP
entity. A protocolDirLocalIndex must not be re-used until the
next agent-restart in the event the protocol directory entry
is deleted."
::= { protocolDirEntry 3 }
protocolDirDescr OBJECT-TYPE
SYNTAX DisplayString (SIZE (1..64))
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"A textual description of the protocol encapsulation.
A probe may choose to describe only a subset of the
entire encapsulation (e.g. only the highest layer).
This object is intended for human consumption only.
This object may not be modified if the associated
protocolDirStatus object is equal to active(1)."
::= { protocolDirEntry 4 }
protocolDirType OBJECT-TYPE
SYNTAX BITS {
extensible(0),
addressRecognitionCapable(1)
}
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This object describes 2 attributes of this protocol
directory entry.
The presence or absence of the `extensible' bit describes
whether or not this protocol directory entry can be extended
by the user by creating protocol directory entries which are
children of this protocol.
An example of an entry that will often allow extensibility is
`ip.udp'. The probe may automatically populate some children
of this node such as `ip.udp.snmp' and `ip.udp.dns'.
A probe administrator or user may also populate additional
children via remote SNMP requests that create entries in this
table. When a child node is added for a protocol for which the
probe has no built in support, extending a parent node (for
which the probe does have built in support),
that child node is not extendible. This is termed `limited
extensibility'.
When a child node is added through this extensibility
mechanism, the values of protocolDirLocalIndex and
protocolDirType shall be assigned by the agent.
The other objects in the entry will be assigned by the
manager who is creating the new entry.
This object also describes whether or not this agent can
recognize addresses for this protocol, should it be a network
level protocol. That is, while a probe may be able to
recognize packets of a particular network layer protocol and
count them, it takes additional logic to be able to recognize
the addresses in this protocol and to populate network layer
or application layer tables with the addresses in this
protocol. If this bit is set, the agent will recognize
network layer addresses for this protoocl and populate the
network and application layer host and matrix tables with
these protocols.
Note that when an entry is created, the agent will supply
values for the bits that match the capabilities of the agent
with respect to this protocol. Note that since row creations
usually exercise the limited extensibility feature, these
bits will usually be set to zero."
::= { protocolDirEntry 5 }
protocolDirAddressMapConfig OBJECT-TYPE
SYNTAX INTEGER {
notSupported(1),
supportedOff(2),
supportedOn(3)
}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object describes and configures the probe's support for
address mapping for this protocol. When the probe creates
entries in this table for all protocols that it understands,
it will set the entry to notSupported(1) if it doesn't have
the capability to perform address mapping for the protocol or
if this protocol is not a network-layer protocol. When
an entry is created in this table by a management operation as
part of the limited extensibility feature, the probe must set
this value to notSupported(1), because limited extensibility
of the protocolDirTable does not extend to interpreting
addresses of the extended protocols.
If the value of this object is notSupported(1), the probe
will not perform address mapping for this protocol and
shall not allow this object to be changed to any other value.
If the value of this object is supportedOn(3), the probe
supports address mapping for this protocol and is configured
to perform address mapping for this protocol for all
addressMappingControlEntries and all interfaces.
If the value of this object is supportedOff(2), the probe
supports address mapping for this protocol but is configured
to not perform address mapping for this protocol for any
addressMappingControlEntries and all interfaces.
Whenever this value changes from supportedOn(3) to
supportedOff(2), the probe shall delete all related entries in
the addressMappingTable."
::= { protocolDirEntry 6 }
protocolDirHostConfig OBJECT-TYPE
SYNTAX INTEGER {
notSupported(1),
supportedOff(2),
supportedOn(3)
}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object describes and configures the probe's support for
the network layer and application layer host tables for this
protocol. When the probe creates entries in this table for
all protocols that it understands, it will set the entry to
notSupported(1) if it doesn't have the capability to track the
nlHostTable for this protocol or if the alHostTable is
implemented but doesn't have the capability to track this
protocol. Note that if the alHostTable is implemented, the
probe may only support a protocol if it is supported in both
the nlHostTable and the alHostTable.
If the associated protocolDirType object has the
addressRecognitionCapable bit set, then this is a network
layer protocol for which the probe recognizes addresses, and
thus the probe will populate the nlHostTable and alHostTable
with addresses it discovers for this protocol.
If the value of this object is notSupported(1), the probe
will not track the nlHostTable or alHostTable for this
protocol and shall not allow this object to be changed to any
other value. If the value of this object is supportedOn(3),
the probe supports tracking of the nlHostTable and alHostTable
for this protocol and is configured to track both tables
for this protocol for all control entries and all interfaces.
If the value of this object is supportedOff(2), the probe
supports tracking of the nlHostTable and alHostTable for this
protocol but is configured to not track these tables
for any control entries or interfaces.
Whenever this value changes from supportedOn(3) to
supportedOff(2), the probe shall delete all related entries in
the nlHostTable and alHostTable.
Note that since each alHostEntry references 2 protocol
directory entries, one for the network address and one for the
type of the highest protocol recognized, that an entry will
only be created in that table if this value is supportedOn(3)
for both protocols."
::= { protocolDirEntry 7 }

SYNTAX INTEGER {

supportedOff(2),

}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object describes and configures the probe's support for
the network layer and application layer matrix tables for this
protocol. When the probe creates entries in this table for
all protocols that it understands, it will set the entry to
notSupported(1) if it doesn't have the capability to track the
nlMatrixTables for this protocol or if the alMatrixTables are
implemented but don't have the capability to track this
protocol. Note that if the alMatrix tables are implemented,
the probe may only support a protocol if it is supported in
the the both of the nlMatrixTables and both of the
alMatrixTables.
If the associated protocolDirType object has the
addressRecognitionCapable bit set, then this is a network
layer protocol for which the probe recognizes addresses, and
thus the probe will populate both of the nlMatrixTables and
both of the alMatrixTables with addresses it discovers for
this protocol.
If the value of this object is notSupported(1), the probe
will not track either of the nlMatrixTables or the
alMatrixTables for this protocol and shall not allow this
object to be changed to any other value. If the value of this
object is supportedOn(3), the probe supports tracking of both
of the nlMatrixTables and (if implemented) both of the
alMatrixTables for this protocol and is configured to track
these tables for this protocol for all control entries and all
interfaces. If the value of this object is supportedOff(2),
the probe supports tracking of both of the nlMatrixTables and
(if implemented) both of the alMatrixTables for this protocol
but is configured to not track these tables for this
protocol for any control entries or interfaces.
Whenever this value changes from supportedOn(3) to
supportedOff(2), the probe shall delete all related entries in
the nlMatrixTables and the alMatrixTables.
Note that since each alMatrixEntry references 2 protocol
directory entries, one for the network address and one for the
type of the highest protocol recognized, that an entry will
only be created in that table if this value is supportedOn(3)
for both protocols."

DESCRIPTION
"The interface or port on which the associated network

If this address mapping was discovered on an interface, this

object, defined in [3,5], for the desired interface.
For example, if an entry were to receive data from
interface #1, this object would be set to ifIndex.1.
If this address mapping was discovered on a port, this
object shall identify the instance of the rptrGroupPortIndex
object, defined in [RFC1516], for the desired port.
For example, if an entry were to receive data from
group #1, port #1, this object would be set to
rptrGroupPortIndex.1.1.
Note that while the dataSource associated with this entry
may only point to index objects, this object may at times
point to repeater port objects. This situation occurs when
the dataSource points to an interface which is a locally
