Dave,
In your config for serial 0, you have service-module t1 timeslots 1-12
This tells the interface that it has half the channels activated, therefore
the bandwidth for that interface is shown as 768K, as reported by the show
int s0 output. It is not checking the clock rate, it is acting off of this
configuration command.
The default behavior of IOS is to assume that bandwidth for any
sub-interface is the same as the main interface, unless you modify that with
the bandwidth command. In s0.302 you have the bandwdith 384 command, which
sets the bandwidth for that interface.
I cannot replicate teh show output for s0.330 in my lab, bandwidth does not
show in the output of the show frame relay map output. Is it teh same as
reported by the show int s.330 command?
