Chapter 5 Distributing Bandwidth Between Queues
Distribution of Remaining Bandwidth Using Ratio
0 packets, 0 bytes
30 second rate 0 bps
queue limit 62 packets
(queue depth/total drops/no-buffer drops) 0/0/0
(pkts output/bytes output) 0/0
The following sample output from the
show policy-map
command indicates that a bandwidth-remaining
ratio of 10 is configured on the parent class-default class of the policy map named vlan10_policy.
Router# show policy-map vlan10_policy
Policy Map vlan10_policy
Class class-default
Average Rate Traffic Shaping

The following sample output from the
show policy-map
command indicates that a bandwidth-remaining
ratio of 100 is configured on the parent class-default class of the policy map named vlan20_policy.
During congestion, the scheduler allocates the subinterface Gigabit Ethernet 1/0/0.20 10 times the
bandwidth that it allocates subinterface Gigabit Ethernet 1/0/0.10.

The following sample output from the
show policy-map
command indicates that a bandwidth-remaining
ratio of 20, 40, and 60 is configured on the class queues precedence_0, precedence_1, and precedence_2,
respectively.
