DescriptionThis 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.
