SNMP Traps
General Explanation
For any event that may set or clear an alarm in the gralAlarm2Table, there is a SNMP
trap that may be sent by the embedded SNMP agent to the manager, if enabled.
Therefore, the list of traps closely reassembles the entries in the alarms table.
Furthermore, there is also a keep-alive trap for letting the SNMP manager that the agent
is working, in case that polling is not being done.
Each trap message has the following fields (except for the keepAlive trap, whose only
object is the agent's IP address
 An identification number associated to the event being signaled.
 A severity indication number.
 A short string description for human readability.
The following list gathers all the available identifiers:
