Hello,
The QoS configuration of the 2530 series (and all ArubaOS-S switches) is described in the Advanced Traffic Management guide. Here is the manual for version 16.10.

Assigning a priority based on source-port
This option assigns a priority to all outbound packets having the specified source-port. You can configure
this option by either specifying the source-port ahead of the qos command or moving to the port context
for the port you want to configure for priority. (If you are configuring multiple source-ports with the same
priority, you may find it easier to use the interface <port-list> command to go to the port context
instead of individually configuring the priority for each port.)
Syntax:
interface <port-list> qos priority <0-7>
Configures an 802.1p priority for packets entering the switch through the specified (source) ports. This
priority determines the packet queue in the outbound ports to which traɝc is sent. If a packet leaves the
switch on a tagged port, it carries the 802.1p priority with it to the next downstream device. You can
configure one QoS classifier for each source-port or group of source-ports.
(Default: No-override)
Syntax:
no interface <port-list> qos
Disables use of the specified source-ports for QoS classifiers and resets the priority for the specified
sourceports to No-override.
