Please click on Advance -> QoS and follow the below setting.

Rules : Use the rules to define the classifiers. After you define the rules, you can
specify action to act upon the traffic that matches the rules

Comment : Enter a descriptive name for this rule for identifying purposes.

MAC Address : Enter MAC address in valid MAC address
format(xx:xx:xx:xx:xx:xx) and click “ Add ” button to add in the MAC group of
each rule. Click “ Remove ” button can remove MAC address in the group of
each rule. There are
10
MAC address maximum allowed in each rule.

Local / Destination IP :
Specify local(LAN)/ destination IP addresses range
required for this rule. If you specify local IP addresses range from 192.168.1.1
to 192.168.2.254. The matches a range of local IP addresses include every
single IP address from the first to the last, so the example above includes
everything from 192.168.1.1 to 192.168.2.254.

DSCP Class : Differentiated services code point, DSCP. Select Any or specify
classify traffic from drop-down list.
The Per-Hop Behavior (PHB) is indicated by encoding a 6-bit value—called the
Differentiated Services Code Point (DSCP)—into the 8-bit Differentiated
Services (DS) field of the IP packet header. Below depicts class for DSCP.

BE : Default PHB, which is typically best-effort traffic

EF : Expedited Forwarding PHB, dedicated to low-loss, low-latency traffic

AF :
Assured Forwarding
PHB, which gives assurance of delivery under
conditions. The AF behavior group defines four separate AF classes.
Within each class, packets are given a drop precedence (high, medium or
low). The combination of classes and drop precedence yields twelve
separate DSCP encodings from AF11 through AF43 (see table)

Protocol : Select Any or specify protocol( TCP , UDP , ICMP , Application ) from
drop-down list. When you select ICMP or Layer 7 Application , the Local/
Destination Port cannot used.

Local Port : Specify local port(LAN port) range required for this rule

Destination Port :
Specify destination port range required for this rule

Action : After configuring rule, a policy rule ensures that a traffic flow gets the
requested treatment in the network.

Remark DSCP : Specify a new DSCP class, if you want to replace or remark the
DSCP
DROP Precedence Class 1 Class 2 Class 3 Class 4
