Detailed Description

Interface Input Mode (Layer 2 Cross-Connect or Bridge / Layer 3).

This file contains the CLI Commands that modify the input mode of an interface. For interfaces in a Layer 2 cross-connect, all packets received on one interface will be transmitted to the other. For interfaces in a bridge-domain, packets will be forwarded to other interfaces in the same bridge-domain based on destination mac address. For interfaces in Layer 3 mode, the packets will be routed.
