QoS Traffic Shaping Basic
Configuration
The WiNG software uses different QoS (Quality of Service)
screens to define WLAN and device radio QoS configurations. The QoS configuration is
separate from WLAN and radio QoS configurations, and is used to configure the
priority of the different DSCP packet types.
QoS values are required to provide priority of service to some packets over others.
For example, VoIP packets get higher priority than data packets to provide a better
quality of service for high priority voice traffic.
The profile QoS screen maps the 6-bit DSCP (Differentiated Service Code
Point) code points to the older 3-bit IP Precedent field located in the
Type of Service byte of an IP header. DSCP is a protocol for specifying and
controlling network traffic by class so that certain traffic types get precedence.
DSCP specifies a specific per-hop behavior applied to a packet.
-
Expand the Network node and
select Quality of
Service (QoS).
Apply traffic shaping to specific applications to apply application
categories. When application and ACL rules are conflicting, applications
have priority, followed by application categories, then ACLs.
The Traffic
Shaping screen displays with the Basic
Configuration tab selected by default.

Network QoS Traffic Shaping Basic Configuration Screen
-
Select Enable to provide
traffic shaping using the defined bandwidth, rate and class mappings.
-
Set the Total Bandwidth
configurable for the traffic shaper. Set the value from either 1 - 1,000 Mbps,
or from 250 - 1,000,000 Kbps.
-
Select + Add Row within
the Rate
Configuration table to set the Class Index (1 - 4) and Rate (in
either Kbps, Mbps or percentage) for the traffic shaper class. Use the rate
configuration to control the maximum traffic rate sent or received on the
device. Consider this form of rate limiting on interfaces at the edge of a
network to limit traffic into or out of the network. Traffic within the set
limit is sent and traffic exceeding the set limit is dropped or sent with a
different priority.
-
Refer to the IP ACL Class
Mapping table and select + Add Row to
apply an IPv4 formatted ACL to the shaper class mapping. Select + Add Row to add
mappings.
-
Refer to the IPv6 ACL Class
Mapping table and select + Add Row to
apply an IPv6 formatted ACL to the shaper class mapping. Select + Add Row to add
mappings.
-
Refer to the App-Category to Class
Mapping table and select + Add Row to apply an application
category to shaper class mapping. Select + Add Row to add mappings by selecting
the application category and its traffic shaper class. For more information on
creating an application category, refer to Create a Custom Application Definition.
-
Refer to the Application to Class
Mapping table and select + Add Row to apply an application to
shaper class mapping. Select + Add Row to add
mappings by selecting the application and its traffic shaper class. For more
information on creating an application, refer to Create a Custom Application Definition.

Select the OK button located
to save the changes to the traffic shaping basic configuration. Select
Reset
