SNMP Traps

The SNMP traps are synchronous notifications generated by the agent which are
sent to the manager. While in other SNMP communications, the manager actively
requests information from the agent, the traps are sent from the agent to the
manager without being explicitly requested. SNMP traps enable an agent to
notify the management station of significant events by way of an unsolicited
SNMP message. The SNMP traps include current sysUpTime value, an OID identi-
fying the type of trap and optional variable bindings. A reference scenario where
SNMP traps are used is shown below:
