QoS Configuration using Source Port

Instead of prioritizing a specific IP address on the Network, it is also possible to prioritize traffic from a
certain source port.
In below steps we will prioritize all traffic using 5060 and 5061 ports on UDP and TCP, which are standard
ports for SIP signaling, similar steps can be performed for any other ports depending on the service/protocol.
1. Similar to prioritizing by IP address, it is needed to enable QoS from QoSGlobal, and enable related
WAN port.
2. Create a class with a priority and upstream bandwidth value from QoSUpstream
3. Create a traffic filter in order to assign the class created in previous step.
4. In our example will set 5061 in TCP source port and 5060 in UDP source port, and setting the DSCP
value to "26 af31" which recommended for VoIP signaling, as shown in below figure.
