Purpose
Specifies the bandwidth-remaining ratio for the
subinterface.
ratio is the value used to determine the amount of unused
bandwidth to allocate to each queue on the subinterface
during periods of congestion. The scheduler allocates the
excess bandwidth relative to other subinterfaces. Valid
values are 1 to 1000. The default value is
platform-dependent.
The router distinguishes between interface types at the
subinterface level when using default bandwidth-remaining
ratios. On the Cisco 10000 series router the default ratio
value is 1 for VLAN subinterfaces and Frame Relay DLCIs.
For ATM subinterfaces, the router computes the default
based on the subinterface speed.
(Optional) Shapes the average or peak rate to the rate you
specify.
average specifies average rate shaping.
peak specifies peak rate shaping.
cir specifies the committed information rate (CIR), in bits
per second (bps).
(Optional) bc specifies the committed burst size, in bits.
(Optional) be specifies the excess burst size, in bits.
Applies the child policy map you specify to the traffic class.
The router applies the QoS actions specified in the child
policy to the traffic class.
child-policy-name is the name of the child policy.
The service-policy command typically requires that
Note
you specify the direction of the traffic using the
input or output keywords. However, when
applying a child policy to a parent policy, do not
specify traffic direction.
