Cisco Systems OL-14253-01 Manual De Usuario

This appendix includes information on CTM GateWay/CORBA’s notifications, fault management, and 
probable cause mapping. This appendix includes the following sections:

The notification service forwards all fault notifications received from managed NEs to the network 
management system (NMS). The notification service also forwards object creation, object deletion, 
attribute change, protection switch, and threshold crossing alert (TCA) events. TMF 814 defines the 
structure and format of attributes for all events and alarms.

The CTM server and the Operations Support System (OSS) host must have Domain Name System (DNS) 
enabled in order to receive notifications. OSS clients running behind a firewall must configure an IIOP 
listening port to enable the TCP connection with the notification server. CTM must configure the 
notification service listening port number to allow OSS clients to communicate with the notification 
service.

CTM creates the notification channel with the QoS parameters shown in the following table.
