Step 10
Router(config-pmap-c)#
bandwidth remaining
ratio
ratio
(Optional) 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.
Step 11
Router(config-pmap-c)#
service-policy
child-policy-name
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.
Note
The service-policy command typically requires that
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.
Step 12
Router(config-pmap-c)#
exit
Exits policy-map class configuration mode.
Step 13
Router(config-pmap)#
exit
Exits policy-map configuration mode.
Step 14
Router(config)#

type

.
subinterface
[
point-to-point
|
multipoint
]
Creates or modifies the interface you specify. Enters
subinterface configuration mode.
type
is the interface type (for example, Gigabit Ethernet).
slot
/
module
/
port
.
subinterface
is the number of the
subinterface that identifies the subinterface (for example,
1/0/0.1).
(Optional)
point-to-point
indicates that the subinterface is
a point-to-point subinterface.
(Optional)
multipoint
indicates that the subinterface is a
point-to-multipoint subinterface.
Step 15
Router(config-if)#
service-policy
{
input

output
}
parent-policy-name
Applies the parent policy to the subinterface.
input
indicates to apply the service policy to inbound
traffic.
output
indicates to apply the service policy to outbound
traffic.
parent-policy-name
is the name of the parent policy map.
Note
When congestion occurs, the class queues receive
bandwidth according to the specified class-level
bandwidth-remaining ratios.
