Fore's fault management is based on an operational status model which can be almost directly mapped into the INMS network element model. Hereafter has each monitored component (node, module, port) an operational state with possible values equivalent to up, down and testing. The alarm state of Fore nodes is determined by INMS on the basis of the actual operational state of the monitored Fore node components. The monitoring of the Fore network is performed by INMS by way of polling status variables in the MIB of the Fore nodes and processing relevant traps generated by the managed entities. The relevant Fore traps are mapped into Gate alarms and are also forwarded to the View component. The next sections describe the monitoring of the operational and alarm states as well as trap mapping for Fore networks. The administrator may set individual Fore node components to the unmanaged or deleted state from the management table. In this case relevant traps take into account the administrative status of the object.
