An SNMP trap is a message the SNMP agent sends to a network management station. For example, an SNMP agent sends a trap when an interface’s status has changed from up to down. The SNMP agent must know the address of the network management station so it knows where to send traps. You can configure this trap destination for the SNMP master agent from Sun Java System Web Server. You can also view, edit, and remove the trap destinations you have already configured. When you configure trap destinations using Sun Java System Web Server, you are actually editing the CONFIG file.
