The Cisco IE 2000 and IE 4010 switches use Internet Protocol (IP) for Ethernet ports. The devices that connect to the switch must also use IP and Ethernet.
For reasons of cybersecurity, you can configure both the IE 2000 and IE 4010 switches to forward only those packets required for the application running on the network. For example, you can configure switches for Johnson Controls BAS systems to permit the BACnet protocol, but block other protocols.
