You can modify the hosts that receive Simple Network Management Protocol (SNMP) traps. You might, for example, need to modify the IP address of the trap host if you install your SNMP-based management application on a different workstation.
Navigate to System > Global Settings > SNMP.
From the SNMP Hosts overview page, select an SNMP host.
Select Actions > Modify.
Enter values for the attributes that you want to modify.
