Command Reference Guide
qos-policy <map name>
Use the qos-policy command within a parent map to divide a quality of service (QoS) policy map into
more specific subclasses. Use the no form of this command to remove the subclass and policy mapping
attributes of the parent map.
Syntax Description

Default Values
No default values are necessary for this command.

Functional Notes
The qos-policy command has two functions in the ADTRAN Operating System (AOS) command line
interface (CLI). In the application described here, it is used to further subdivide a class into more specific
subclasses. From the interface configuration command set, it is used to apply a QoS map to the interface.
Refer to
qos-policy on page 1699
the qos-policy command in the interface configuration command set.
When subdividing a QoS policy map, the most specific (or child map) QoS map should be created first and
then the map is referenced using the qos-policy command within the QoS map entry of the base map that
is being subdivided. The base (or parent map) is applied to the interface using the qos-policy out
command (refer to
qos-policy on page
Only two levels of maps are allowed, meaning child maps (or subclasses) cannot have additional child
maps beneath them. A child map cannot reference another child map. If the child map referenced by this
command is deleted, then the qos-policy command is also deleted from the parent map.
Usage Examples
For example, the following configuration uses the SHAPEEVCS QoS map to constrain each VLAN's
Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) traffic to specific rates. The virtual
local area network (VLAN) 2 traffic that is put into the shaping queue is broken up into class-based queuing
(CBQ) or low latency queuing (LLQ) subclasses using the CLASSQUEUES QoS map. Traffic not matching
a QoS map entry is treated as best effort, and is dynamically assigned to a best effort weighted fair queue
(WFQ).
(config)#qos map CLASSQUEUES 10
