I think you almost nailed it, Hobbs. The way I read it is that the
Prec4 class doesn't require shaping. I think this would do it:
policy-map policy
class fa0/0
bandwidth 128
shape average 256000
class prec4
bandwidth 384
The bandwidth statement is a minimum guarantee, but will allow the
traffic to go up to the full bandwidth, if it is available.

Does that satisfy the requirements?
Not sure why you are using nested policies...

Dear Experts,
I am confused what would be the solution to below requirements. Please
help!
Define two classes of service besides the default.
Class Fa0/0 matches all the traffic coming from input interface fa0/0.
Class IP-Prec matches all the traffic with an IP Precedence of 4.
Class Fa0/0 is ensured a bandwidth of 128 Kbps and the output is shaped to
256 Kbps.
Class IP-Prec is ensured a bandwidth of 384 Kbps. But if enough bandwidth
is available, the class can obtain the throughput up to the peak of 512
Kbps
I tried the following configuration but when I apply it to interface, I get
*"GTS : Can be enabled only at the first level"*
Class Map match-all Fa0/0 (id 1)
Match input-interface FastEthernet0/0
Class Map match-all IP-Prec (id 2)
Match ip precedence 4
Policy Map Fa0/0
Class Fa0/0
