Qos-Policy Out - Command - ADTRAN 5000 Series Command Reference Manual

Command Reference Guide
qos-policy out <mapname>
Use the qos-policy out command to apply a previously-configured QoS map to an interface. Use the no
form of this command to remove the map from the interface. The out keyword specifies that this policy
will be applied to outgoing packets.
Syntax Description
<mapname>
Default Values
No default value is necessary for this command.
Applicable Platforms
This command applies to the NetVanta 1000R, 3000, 4000, and 5000 and Total Access 900 Series units.
Command History
Release 6.1
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 cross-connect 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.
