<p><P>PROBLEM TO BE SOLVED: To report the occurrence of a fault to an SNMP manager without allowing the network interface of a communication apparatus monitored by SNMP to be redundant. <P>SOLUTION: Fault monitoring programs 221, 321 detect communication faults in communication boards 20, 30. When the communication fault is detected in the self communication boards 20(30), SNMP agents 222, 322 determine whether an address imparted to the communication board 20(30) is usable or not, detect the connection state of the network and transmit an SNMP trap for reporting the occurrence of the fault to the SNMP manager 100 when the address is usable, change the address into the other one when the address is unusable and transmit a SNMP trap transmission request to the other SNMP agents 322, 222. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
