The Fore TA processes only Fore traps signalizing an operational state change in a network component (node, module, port) monitored by INMS. Besides updating its internal MIB, Gate generates alarms containing information about the received Fore trap and forwards them to the View components in the network. The mapped Gate alarms are displayed within the View component under the alarm category "Fore".
Let us consider trap number 1093 for instance. The Prolog rule must include control structures to handle the special case of switch model ASX-4000, in which a logical node can contain more than one physical board.
trap_mapping(N, 6, 1093 /*asxFabricDown*/,
[[boardIndex, Board] = Board,
[trapLogIndex,0] = _],
Events
) :-
% if switchModel == asx4000: can't report a board alarm
% since boards not modelled -> map trap to modules
switchModel(N, asx4000),
concat_atom(['Board number ', Board, ' down or hot-swapped'], Details),
% build list of alarms for all contained modules
setof(Mod, module2board(N, Board, Mod), Modules),
setof(nodeAlarm(N, physModule(N, M), 'Major', fabricDownTrapReceived,
physModule(N, M), Details, down),
member(M, Modules), Events), !
;
% if switchModel = asx4000 -> board == node.
not switchModel(N, asx4000),
Events = [nodeAlarm(N, physNode(N), 'Critical', fabricDownTrapReceived,
physNode(N), 'Physical node down or hot-swapped', down)],
!.
Table 6 lists the mapping between relevant Fore traps and the operational state of the respective components in the INMS network element model. Table 7 lists the mapping between relevant Fore traps and Gate alarms. The Reason and EventDetails fields in the Gate alarms correspond to the reason given in Table 6.
