Look into "configuring simplex interfaces" or "configuring simplex
Ethernet." IOS commands will force an interface to be transmit-only
or receive-only.
Another application for this is to get 10 Mbps full duplex on old
routers, as long as you have two Ethernets. Make one transmit-only
and the other receive-only, and build a Y-cable that connects the
transmit wires to one and the receive wires to the other, with a
conventional Ethernet at the other end. The combined end can plug
into a switch port and run FDX, although there's no VLAN support.
