RSTP and IGMP Messaging
RSTP and IGMP messages usually consume a very small amount of network
bandwidth. Set up the IGMP query period based on your application requirements.
Scheduling Certain Explicit Messages
Depending on your application requirements, you can also configure certain explicit
messages to be transmitted either cyclically or upon the occurrence of a change of
state event. For example, you can periodically monitor a device using SNMP query,
Web pages, EtherNet/IP, and Modbus TCP. The cyclic period should be configured
so that the total load consumed by explicit messaging does not exceed 10% of
network capacity.
