Functionality

Ethernet channel supervision SCHLCCH represents X1/LAN, X2/LAN and X3/LAN
Ethernet channels.
An unused Ethernet port can be set "Off" with the setting Configuration/
Communication/Ethernet/Port Modes. This setting closes the port from software,
disabling the Ethernet communication in that port. Closing an unused Ethernet port
enhances the cyber security of the relay.
