Interesting question, and some interesting tidbits ...
Watch the ugly word wrap):

From this link:
... bandwidth Inheritance
Before the introduction of the *bandwidth inherit* command option, when the
bandwidth value was changed on the main interface, existing subinterfaces
did not inherit the bandwidth value from the main interface. If the
subinterface was created before the bandwidth was changed on the main
interface, then the subinterface would receive the default bandwidth of the
main interface, not the configured bandwidth. Additionally, if the router
was subsequently reloaded, the bandwidth of the subinterface would then
change to the bandwidth configured on the main interface.
Johan - the way I have always looked at this from "where is IP running, and
where is the routing protocol?" This command most applies to routing
protocols. If I am using sub interfaces, then I have always configured
the bandwidth statement there.
HTH,
