EUCN Switches
EUCN FTE network security is achieved with the use of Level 1 Honeywell CF9 and Level 2 Industrial
Ethernet switch (Cisco IE 3000) configurations. In larger EUCN topologies, you must configure the
industrial Ethernet switch as a Level 1 and Level 2 switch, known as split switch configuration.
In a split switch, a designated portion of the ethernet switch operates as a Level 1 switch and the
remaining portion as a level 2 switch.
