Managed Industrial Switch
Ethernet switch with configuration and diagnostic features such as VLANs, port mirroring, redundancy, and traffic prioritization.
The Explain card
- Plain English
- A managed switch is one you can log into and configure. It supports VLANs, port mirroring, ring redundancy, traffic priority and per port diagnostics, and it is built for a panel rather than a desk.
- Example
- The cell switch keeps the safety I/O on its own VLAN, mirrors the drive's port to a laptop for a packet capture, and closes a DLR ring with the controller.
- Why it matters
- An unmanaged switch is fine for a few devices and blind when something goes wrong. The managed one tells you which port is flapping, which device is flooding the network, and lets you keep motion traffic away from the HMI's screen updates.
- Hook
- A switch you can ask what happened.
