Regarding the method of receiving an SNMP Trap, when
NOTE:
software other than Server Management Manager receives an SNMP
Trap, Server Management Manager may not be able to receive an
SNMP Trap correctly due to a clash on the SNMP Trap board.
In this case, select "Use SNMP Trap Service".
Note that when you select "Use SNMP Trap Service", the function that
restricts receiving SNMP Traps by SNMP community names cannot be
used. (The function can be configured from [Options] - [Customize] -
[Environment] in the Operation Window.)
When you have selected "Use own method", be sure to not start up
"SNMP Trap Service".
