SNMP Traps
OMCI generates events that result in Simple Network Management Protocol (SNMP) traps or operating system event
logs. This section describes the traps, also known as alerts, generated by OMCI.
OMCI generates events in response to changes in the status of sensors and other monitored parameters. When an
event with predefined characteristics occurs on your system, the SNMP subagent sends information about the event,
along with trap variables, to the management console.
Each status change event generates a unique identifier called the TrapID and a trap description that describes the
event. The TrapID and message uniquely describe the severity and cause of the event. The TrapID and description also
provide other relevant information such as the location of the event and the previous state of the monitored item.
Trap Variables
This section describes the variables that are sent to the management console to provide additional information about a
trap or alert generated by some event on your system. The trap variables listed here apply to all Instrumentation traps.
Trap variables are sent in the order listed and are reserved for use only in traps. When a varbind is created for a trap
variable, a zero is appended to the object ID (OID) to create the OID for the varbind.
