Omron NX Series User Manual

The EtherNet/IP port SNMP agent function supports SNMPv1 (RFC1157) and SNMPv2C (RFC1901).
Use the SNMPv1 or SNMPv2C protocol to manage the EtherNet/IP port with the SNMP manager. Y
ou
can also use both the SNMPv1 and SNMPv2C protocols together at the same time.
SNMP Traps
When a failure or some other specific problem occurs, a status report called a trap is sent.
This enables monitoring changes in status even if the SNMP manager does not monitor the
EtherNet/IP port periodically.
However
, traps use UDP. Therefore, you cannot check to see if the SNMP manager receives traps
from the EtherNet/IP port.
Thus, depending on the network status, some traps may not reach the SNMP manager.
