Hi Brian,
So, this means that ultimately we are creating congestion in our Output
Queue as CIR/AIR as a whole would be 512 K and Packet loss would occur
if both of the classes are sending at their higher rate.
Thanks,
Gops

Gops,
With your configuration you're saying that telnet is guaranteed
384Kbps during times of congestion, but cannot exceed 512Kbps on
average.
The HTTP class is saying that you cannot exceed 512Kbps on average, and
if using "bandwidth" is guaranteed 128Kbps at a minimum, or if using
"priority"
is guaranteed prioritization up to 128Kbps, can burst up to 512Kbps, but
will be policed at 128Kbps in times of congestion.
The difference with nesting the policy is that you can say class
X and class Y can send up to 512Kbps as an aggregate, whether class X is
using 1Kbps and class Y is using 511Kbps. With the non-aggregate
configuration as below classes HTTP and TELNET can send 512Kbps +
512Kbps = 1024Kbps as a whole.
