If the remote switch doesn't support it, only outgoing traffic will be
split across both ports.  Incoming traffic will probably come in on the
first port that came up, or the switch may decide that there's a
routing loop (or other misconfiguration) because the same MAC address
is seen on both ports, and disable one of the ports (or even both). 
Most managed switches should support it; they may call it trunking.
