7.5 Traps
While a management station can poll, at fixed time interval, all the agents it knows for some key information,
each agent is responsible for notifying the management station of any alarm condition. These events are
communicated in SNMP messages known as traps.
The following parameters shall be set in order to correctly configure traps:
 SNMP Agent Port: 162.
 SNMP Agent Transport protocol: IP/UDP.
7.5.1 SNMPv1
ARK6 devices transmit alarm-specific traps. For every Trap Manager there is a different SNMPv1 trap definition:

alarmTrap2 TRAP-TYPE
