13.1 Sending SNMP traps
The device immediately reports unusual events which occur during normal operation to the network
management station. This is done by messages called SNMP traps that bypass the polling
procedure (“polling” means querying the data stations at regular intervals). SNMP traps allow you
to react quickly to unusual events.
Examples of such events are:

Hardware reset

Changes to the configuration

Segmentation of a port
The device sends SNMP traps to various hosts to increase the transmission reliability for the
messages. The unacknowledged SNMP trap message consists of a packet containing information
about an unusual event.
The device sends SNMP traps to those hosts entered in the trap destination table. The device lets
you configure the trap destination table with the network management station using SNMP.
