Configuring QoS Settings on Aruba Switches

QoSQuality of Service. It refers to the capability of a network to provide better service and performance to a specific network traffic over various technologies. is used to classify and prioritize traffic throughout a network. QoS enables you to establish an end-to end traffic-priority policy to improve the control and throughput of important data. You can manage available bandwidth so that the most important traffic goes first.

Aruba Central allows you to configure QoS settings on the switch through the UI. The setting that can be configured using the UI are:

Creating QoS traffic policies on switches in your network to enable traffic-handling rules across the network.

Defining QoS classes for a QoS Policy.

Changing the priorities of traffic from various segments of your network as your business needs change.

Creating a QoS Traffic Policy

1. In the Network Operations app, select one of the following options:

To select a switch group in the filter:

a. Set the filter to a group containing at least one switch.

The dashboard context for the group is displayed.

b. Under Manage, click Devices > Switches.

c. Click the Config icon to view the switch configuration dashboard.

To select a switch in the filter:

a. Set the filter to Global or a group containing at least one switch.

b. Under Manage, click Devices > Switches.

A list of switches is displayed in the List view.

c. Click a switch under Device Name.

The dashboard context for the switch is displayed.

d. Under Manage, click Device.

The tabs to configure the switch is displayed.

2. Click QoS. The QoS page is displayed.

3. In the QoS Traffic Policy accordion, click + to add a new QoS traffic policy.

4. Configure the following parameters.

Table 1: Configuring QoS policy

Name	Description	Value
Policy Name	The name of the QoS policy.	A string
Target	The target where the policy is applied.	Port or VLAN
ID	The IP address for static IP assignment. This field is enabled only when you select Static from the IP Assignment drop-down.	IPv4 address

5. Click Save.

Editing a QoS Policy

To edit a QoS policy, point to the row for the Qos policy, and click the edit icon.

Deleting a QoS Policy

To delete a QoS policy, point to the row for the Qos policy, and click the delete icon.

Adding a QoS Class for the Policy

To define a QoS class for the a policy, complete the following steps:

1. Select a QoS policy from the New QoS Policy table. The QoS Class table is displayed below the New QoS Policy table with the configured QoS classes.

2. Click + to add a QoS classifier for the selected policy. The Add QoS classifier Classifier window is displayed.

3. Configure the following parameters.

Table 2: Configuring QoS class

Name	Description	Value
Class Name	The class name of the QoS policy.	A string
Packet Matching Criteria
Protocol	The IP address for static IP assignment. This field is enabled only when you select Static from the IP Assignment drop-down.	IPv4 address
Source	The type of source for which you want to apply a policy.	Any, Network, or Host. If you select Network, enter the IP address and wildcard mask . If you select Host, enter the IP address.
Destination	The type of destination for which you want to apply a policy.	Any, Network, or Host. If you select Network, enter the IP address and wildcard mask . If you select Host, enter the IP address.
Source Port(s)	The port numbers of source.	Numeric value
Destination Port(s)	The port numbers of destination.	Numeric value
Actions
DSCP	Select a Differentiated Service Code Point (DSCPDifferentiated Services Code Point. DSCP is a 6-bit packet header value used for traffic classification and priority assignment. ) from the drop-down.	DSCP value range from 0 to 63. Default value is No Change. In few cases, such as 10| af11 and 10| af12
Priority	Select a priority value for the selected DSCP.	The priority range from 0 to 7. 0 – Normal Priority 1 – Low Priority 7 – High Priority Default value is No Change

Editing a QOS Class

To edit a QoS Class, point to the row for the Qos policyclass, and click the edit icon.

Deleting a QOS Class

To delete a QoS Class, point to the row for the Qos policyclass, and click the delete icon.

Configuring DSCP Map

DSCP map table displays mappings between Incoming DSCP and priority.

To change priority value associated with a DSCP code point, complete the following steps:

1. In the Network Operations app, select one of the following options:

To select a switch group in the filter:

a. Set the filter to a group containing at least one switch.

The dashboard context for the group is displayed.

b. Under Manage, click Devices > Switches.

c. Click the Config icon to view the switch configuration dashboard.

To select a switch in the filter:

a. Set the filter to Global or a group containing at least one switch.

b. Under Manage, click Devices > Switches.

A list of switches is displayed in the List view.

c. Click a switch under Device Name.

The dashboard context for the switch is displayed.

d. Under Manage, click Device.

The tabs to configure the switch is displayed.

2. Click QoS. The QoS page is displayed.

3. Expand the DSCP Map accordion.

4. Select the Incoming DSCP row for which you want to change the priority and click the edit icon. The Edit DSCP window is displayed.

5. Select the priority value from the drop-down.

6. Click OK.
