3.3.6 SNMP Trap
SNMP trap is a type of entrance. When this entrance is reached, the SNMP managed devices
actively notify the NMS, instead of waiting for the polling of NMS. On an SNMP-enabled network,
the agents on managed devices can report errors to the NMS anytime, without the need of
waiting for the polling of NMS. The errors are reported to the NMS through traps.
