themselves in Management Information Bases (MIBs) and
return this data to the SNMP requesters.

SNMP Traps Notifications or Event Reports are occurrences of Events in a
Managed system, sent to a list of managers configured to
receive Events for that managed system. These Event
Reports are called Traps in SNMP. The Traps provide the
value of one or more instances of management information.
Any SNMP enabled Device generates Fault Reports (Traps)
that are defined in the MIB (which the SNMP Agent has
implemented).
The Trap Definition vary with the SNMP Version (which
defines the messaging format), but the information contained
in these are essentially identical. The major difference
between the two message formats is in identifying the events.
