Typically trunking is the process of passing multiple VLAN's down the same
Ethernet interface (the VLAN's are "trunked" together). A port-channel is
the process of bonding several Ethernet interfaces together into a single
channel-group (Cisco calls this EtherChannel) that could (if you set up
trunking) pass multiple VLAN's. Think of VLAN's = Broadcast Domain = Layer
3 Subnet. EtherChannel is just a way to get around the limit of a 100MB
feed when you really need 400MB between two pieces of equipment and you
don't want to use a routing protocol to do balancing across multiple paths,
you just want a bigger pipe.
