EXAMPLE 2
Peer classes refers to the traffic classes in a policy map at same level. If a parent
is not having the bandwidth, its child may have the bandwidth configured.
ALU(config)# policy-map p1
ALU(config-qos-p1)# class c1
ALU(config-qos-p1-c1)# service-policy p2
ALU(config)# policy-map p2
ALU(config-qos-p2)# class c2
ALU(config-qos-p2-c2)# bandwidth percent 10
In the above example, policy p1 is having child policy p2 inside the class c1.
Traffic class c1 is not having bandwidth configured, but the child class is having
the bandwidth configured. In this particular case (only one Traffic) whole
bandwidth is available for the traffic c1.

XAMPLE 3
When a parent policy is having more than one traffic class and some of the class
is having the bandwidth configured.
Consider a policy p1 with two classes c12 and c13 with bandwidth 30 and 70
respectively, and policy p2 included in p1 under class c12:
ALU(config)# policy-map p1
ALU(config-qos-p1)# class c12
ALU(config-qos-p1-c12)# service-policy p2
ALU(config-qos-p1-c12)# bandwidth percent 30
ALU(config)# policy-map p1
ALU(config-qos-p1)# class c13
ALU(config-qos-p1-c13)# bandwidth percent 70
Consider the policy p2 with class c2 having bandwidth 10.
ALU(config)# policy-map p2
ALU(config-qos-p2)# class c2
ALU(config-qos-p2-c2)# bandwidth percent 10
In this case, the class c2 will get 10% of the zero (class c11 share is 0). It is the
time of the congestion but if the bandwidth is unused by the other classes, then c2
can have some bandwidth (10% of available bandwidth).
