qos-policy out
<name>
Use the
qos-policy out
command to apply a previously-configured QoS map to outgoing packets on an
interface. Use the
no
form of this command to remove the map from the interface.
Syntax Description
<name>
Specifies the name of a previously-created QoS map (refer to
on page 431 for more information).
Default Values
No default value is necessary for this command.
Functional Notes
When a QoS policy is applied to an interface, it may be disabled if the interface bandwidth is not adequate
to support the requested bandwidth on the map set. Once the bandwidth problem is resolved, the map will
work again. The bandwidth will be rechecked on any of the following changes:
1. A priority or class-based entry is added to, deleted from, or changed in a QoS map set.
2. The interface bandwidth is changed by the
bandwidth
command on the interface.
3. A QoS policy is applied to an interface.
4. A bind is created that includes an interface with a QoS policy.
5. The interface queuing method is changed to fair-queue to use weighted fair queuing.
6. The interface operational status changes.
7. The interface bandwidth changes for other reasons (e.g., when ADSL finishes training).
In order to prevent the map from being disabled in cases of temporary inadequate bandwidth (e.g., a single
link goes down in a dual T1 multilink configuration where the map requests more than one T1's worth of
bandwidth), the QoS map uses the maximum theoretical bandwidth on an interface, not the actual
bandwidth at that time. This actually helps QoS keep higher priority class-based traffic working better than
best-effort traffic when the bandwidth drops.
Usage Examples
The following example applies the QoS map
VOICEMAP
to BVI interface 1:
ProCurve(config)#
interface bvi 1
ProCurve(config-bvi 1)#
qos-policy out VOICEMAP
