Hi, Tim:

With fallback bridging, the switch bridges together two or more VLANs
or routed ports, essentially
connecting multiple VLANs within one bridge domain. Fallback bridging
forwards traffic that the switch
does not route and forwards traffic belonging to a nonroutable
protocol such as DECnet.

You can find this in config of c3550.
