| mplsFTNIndexNext |
.1.3.6.1.2.1.10.166.8.1.1 |
|
This object contains the next available valid value to
be used for mplsFTNIndex when creating entries in the
mplsFTNTable.
When creating a new conceptual row (configuration
entry) in mplsFTNTable with an SNMP SET operation the
command generator (Network Management Application) must
first issue a management protocol retrieval operation
to obtain the current value of this object.
If the command responder (agent) does not wish to allow
creation of more entries in mplsFTNTable, possibly
because of resource exhaustion, this object MUST return
a value of 0.
If a non-zero value is returned the Network Management
Application must determine whether the value is indeed
still unused since two Network Management Applications
may attempt to create a row simultaneously and use the
same value.
If it is currently unused and the SET succeeds, the
agent MUST change the value of this object to a
currently unused non-zero value (according to an
implementation specific algorithm) or zero (if no
further row creation will be permitted).
If the value is in use, however, the SET fails and the
Network Management Application must then reread this
object to obtain a new usable value.

.1.3.6.1.2.1.10.166.8.1.2 |
|
Indicates the last time an entry was added, deleted or
modified in mplsFTNTable. Management stations should
consult this object to determine if mplsFTNTable
requires their attention. This object is particularly
useful for applications performing a retrieval on
mplsFTNTable to ensure that the table is not modified
during the retrieval operation.
|

.1.3.6.1.2.1.10.166.8.1.4 |
|
Indicates the last time an entry was added, deleted or
modified in mplsFTNMapTable. Management stations should
consult this object to determine if the table requires
their attention. This object is particularly useful
for applications performing a retrieval on
mplsFTNMapTable to ensure that the table is not
modified during the retrieval operation.

Network Management Application SHOULD retrieve the
current value of mplsFTNIndexNext to determine the next
valid available value of mplsFTNIndex.
|
| mplsFTNRowStatus |
.1.3.6.1.2.1.10.166.8.1.3.1.2 |
|
Used for controlling the creation and deletion of this
row. All writeable objects in this row may be modified
at any time. If a Network Management Application
attempts to delete a conceptual row by setting this
object to 'destroy' and there are one or more entries
in mplsFTNMapTable pointing to the row (i.e., when
mplsFTNIndex of the conceptual row being deleted is
equal to mplsFTNMapCurrIndex for one or more entries in
mplsFTNMapTable), the agent MUST also destroy the
corresponding entries in mplsFTNMapTable.

.1.3.6.1.2.1.10.166.8.1.3.1.3 |
|
The description of this FTN entry. Since the index for
this table has no particular significance or meaning,
this object should contain some meaningful text that an
operator could use to further distinguish entries in
this table.

This object MUST NOT be set to unknown(0) when
mplsFTNMask has bit positions sourceAddr(0) or
destAddr(1) set to one.
When both these bit positions of mplsFTNMask are set to
zero the value of mplsFTNAddrType SHOULD be set to
unknown(0) and the corresponding source and destination
address objects SHOULD be set to zero-length strings.

which any one or more of this entry's counters suffered
a discontinuity. If no such discontinuities have
occurred since the last re-initialization of the local
management subsystem, then this object contains a zero
value.
|
| mplsFTNTable |
.1.3.6.1.2.1.10.166.8.1.3 |
|
This table contains the currently defined FTN entries.
This table allows FEC to NHLFE mappings to be
specified. Each entry in this table defines a rule to
be applied to incoming packets (on interfaces that the
FTN entry is activated on using mplsFTNMapTable) and an
action to be taken on matching packets
(mplsFTNActionPointer).
This table supports 6-tuple matching rules based on one
or more of source address range, destination address
range, source port range, destination port range, IPv4
Protocol field or IPv6 next-header field and the
DiffServ Code Point (DSCP) to be specified.
The action pointer points either to instance of
mplsXCEntry in MPLS-LSR-STD-MIB when the NHLFE is a non-
TE LSP, or to an instance of mplsTunnelEntry in the
MPLS-TE-STD-MIB when the NHLFE is an originating TE
tunnel.
|
| mplsFTNMapTable |
.1.3.6.1.2.1.10.166.8.1.5 |
|
This table contains objects which provide the
capability to apply or map FTN rules as defined by
entries in mplsFTNTable to specific interfaces in the
system. FTN rules are compared with incoming packets
in the order in which they are applied on an interface.
The indexing structure of mplsFTNMapTable is as
follows.
- mplsFTNMapIndex indicates the interface to which the
rule is being applied. A value of 0 represents the
application of the rule to all interfaces.
- mplsFTNMapPrevIndex specifies the rule on the
interface prior to the one being applied. A value of
0 specifies that the rule is being inserted at the
head of the list of rules currently applied to the
interface.
- mplsFTNMapCurrIndex is the index in mplsFTNTable
corresponding to the rule being applied.
This indexing structure makes the entries in the table
behave like items in a linked-list. The object
mplsFTNMapPrevIndex in each conceptual row is a pointer
to the previous entry that is applied to a particular
interface. This allows a new entry to be 'inserted' at
an arbitrary position in a list of entries currently
applied to an interface. This object is self-
adjusting, i.e., its value is automatically adjusted by
the agent, if necessary, after an insertion or deletion
operation.
Using this linked-list structure, one can retrieve FTN
entries in the order of application on a per-interface
basis as follows:
- To determine the first FTN entry on an interface
with index ifIndex perform a GETNEXT retrieval
operation on mplsFTNMapRowStatus.ifIndex.0.0; the
returned object, if one exists, is (say)
mplsFTNMapRowStatus.ifIndex.0.n (mplsFTNMapRowStatus
is the first accessible columnar object in the
conceptual row). Then the index of the first FTN
entry applied on this interface is n.
- To determine the FTN entry applied to an interface
after the one indexed by n perform a GETNEXT
retrieval operation on
mplsFTNMapRowStatus.ifIndex.n.0. If such an entry
exists the returned object would be of the form
mplsFTNMapRowStatus.ifIndex.n.m. Then the index of
the next FTN entry applied on this interface is m.
- If the FTN entry indexed by n is the last entry
applied to the interface with index ifIndex then the
object returned would either be:
1.mplsFTNMapRowStatus.ifIndexNext.0.k, where
ifIndexNext is the index of the next interface in
ifTable to which an FTN entry has been applied, in
which case k is the index of the first FTN entry
applied to the interface with index ifIndexNext;
or:
2.mplsFTNMapStorageType.firstIfIndex.0.p, if there
are no more entries in mplsFTNMapTable, where
firstIfIndex is the first entry in ifTable to
which an FTN entry has been mapped.
Use the above steps to retrieve all the applied FTN
entries on a per-interface basis in application order.
Note that the number of retrieval operations is the
same as the number of applied FTN entries (i.e., the
minimum number of GETNEXT operations needed using any
indexing scheme).
Agents MUST NOT allow the same FTN entry as specified
by mplsFTNMapCurrIndex to be applied multiple times to
the same interface.
Agents MUST NOT allow the creation of rows in this
table until the corresponding rows are created in the
mplsFTNTable.
If a row in mplsFTNTable is destroyed, the agent MUST
destroy the corresponding entries (i.e., ones with a
matching value of mplsFTNCurrIndex) in this table as
well.
