Two drawbacks to SNMP traps are that they are sent using UDP, which is not a guaranteed delivery mechanism, and that they are not
acknowledged by the receiver.
An SNMP trap message contains the trap’s enterprise OID, the agent IP address, a generic trap ID, the specic trap ID, a time stamp, and
zero or more variable bindings (varbinds). The combination of an enterprise OID and a specic trap ID uniquely identies each Server
Administrator-dened trap. A varbind consists of an OID and its value and provides additional information about the trap.
In order for a management system to receive SNMP traps from a managed system, the node must be congured to send traps to the
management system. Trap destination conguration depends on the operating system. When this conguration is done, a management
application on the management system can wait for traps and act on them when received.
