4.6.2 SNMP traps
If unusual events occur during normal operation of the RS2-4R, they are
reported immediately to the management station. This is done by means of
so-called traps- alarm messages - that bypass the polling procedure
("Polling" means querying the data stations at regular intervals). Traps make
it possible to react quickly to critical situations.
Examples of such events are:
D a hardware reset
D changing the basic device configuration
D segmentation of a port
Traps can be sent to various hosts to increase the transmission reliability for
the messages. A trap message consists of a packet that is not acknowl
-
edged.
The management agent sends traps to those hosts that are entered in the
trap destination table. The trap destination table can be configured with the
management station via SNMP.
