As long as you change the interface to consider 100%
bandwidth you should be ok. I see you have done this
but sometimes it is easy to forget. Also you may want
to be careful that the interface has not had a
previous requirement to change the default bandwidth
for any reason.

And remember the keyword load is used in your example.
 So you should be keenly aware if other terms might be
used as well. I would recommend changing the
variables in your example and changing the example
given in CCO and performing a bit a criss-cross,
produce the condition, observe the results and work in
a methodical fashion. Use extended pings to help
produce the desired congestion. Caslow gives great
examples that can be used for QoS examples like this
one and others.

The example listed in the link above should give you
an example of the correct verification commands as a
very similar example as you have presented - so you
can compare your output line for line.
