Contemporary Controls says it often been asked this question, “When should I use a managed Ethernet switch?” R&D Manager Bennet Levine explains, in a white paper that discusses the role of plug-and-play (PnP) switches, which leads to the question, “What is a managed switch?” Levine explains that a managed switch contains all the features of unmanaged switches plus SNMP, IGMP snooping, port mirroring, VLAN, rate control, and more.

If you have a larger network, Levine says, you may want to use managed switches. Use managed switches, he says, when you:• Have a large network you will probably need managed switches simply to be able to diagnose problems.• Have multicast traffic on your network (for example when using EtherNet/IP? ).• Downtime is expensive.• Are interconnecting office and control networks.
