SNMP Traps

An SNMP agent reports an error of a storage system to SNMP manager using the trap report function.

If an error occurs, an SNMP agent issues an SNMP trap to an SNMP manager to report a failure. Issuing

an SNMP trap, an SNMP agent also reports a product number, a nickname, a reference code, and

an identiﬁer of component.

Table 4 on page 13 lists the events that trigger an SNMP agent trap.
