Warning:

Priority Queuing (PQ) deprecated from NetScaler 12.0 build 56.20 onwards and as an alternative, Citrix recommends you to use the AppQoE feature. However, Priority Queuing (PQ) is removed and no longer available on the Citrix ADC appliance release 13.1 onwards. For more information, see AppQoE topic.

The Citrix ADC appliance supports prioritization of client requests with its priority queuing feature. This feature allows you to designate certain requests, such as those from important clients, as priority requests and sends them to the “front of the line,” so that the appliance responds to them first. This allows you to provide uninterrupted service to those clients through demand surges or DDoS attacks on your website.

To configure priority queuing on a virtual server by using the CLI

At the command prompt, type:

set lb vserver <name> -pq <Value>
<!--NeedCopy-->

Example:

set lb vserver Vserver-LB-1 -pq yes
<!--NeedCopy-->

To configure priority queuing on a virtual server by using the GUI

Navigate to Traffic Management > Load Balancing > Virtual Servers, and open the virtual server.
In Advanced Settings, click Traffic Settings, and select Priority Queuing.

Note: Configure priority queuing globally for it to function correctly.
