3.3 Using the Traffic Manager
3.3.1 Managing QoS (Quality of Service) Bandwidth
Quality of Service (QoS) allows you to set the bandwidth priority and manage network traffic.
To set up bandwidth priority:
1. From the navigation panel, go to General > Traffic Manager >
QoS tab.
2. Click ON to enable QoS. Fill in the upload and download bandwidth fields.
NOTE: Get the bandwidth information from your ISP.
3. Click Save .
NOTE: The User Specify Rule List is for advanced settings. If you want to prioritize specific network applications and network services, select
User-defined QoS rules or User-defined Priority from the drop-down list on the upper-right corner.

4. On the user-defined QoS rules page, there are four default online service types – web surf, HTTPs and file transfers.
Select your preferred service, fill in the Source IP or MAC ,
Destination Port , Protocol , Transferred and Priority , then click Apply . The information will be configured in the QoS rules screen.
NOTES:
• To fill in the source IP or MAC, you can:
a) Enter a specific IP address, such as "192.168.122.1".
b) Enter IP addresses within one subnet or within the same IP pool, such as “192.168.123.*”, or “192.168.*.*”
c) Enter all IP addresses as “*.*.*.*” or leave the field blank.
d) The format for the MAC address is six groups of two hexadecimal digits, separated by colons (:), in transmission order (e.g. 12:34:56:aa:bc:ef)
• For source or destination port range, you can either:
a) Enter a specific port, such as “95”.
b) Enter ports within a range, such as “103:315”, “>100”, or
“<65535”.
• The Transferred column contains information about the upstream and downstream traffic (outgoing and incoming network traffic) for one section. In this column, you can set the network traffic limit (in
KB) for a specific service to generate specific priorities for the service assigned to a specific port. For example, if two network clients, PC
1 and PC 2, are both accessing the Internet (set at port 80), but PC 1 exceeds the network traffic limit due to some downloading tasks, PC
1 will have a lower priority. If you do not want to set the traffic limit, leave it blank.
5. On the User-defined Priority page, you can prioritize the network applications or devices into five levels from the userdefined QoS rules ’ dropdown list. Based on priority level, you can use the following methods to send data packets:
• Change the order of upstream network packets that are sent to the Internet.
• Under Upload Bandwidth table, set Minimum Reserved
Bandwidth and Maximum Bandwidth Limit for multiple network applications with different priority levels. The percentages indicate the upload bandwidth rates that are available for specified network applications.
NOTES:
• Low-priority packets are disregarded to ensure the transmission of high-priority packets.
• Under Download Bandwidth table, set Maximum Bandwidth
Limit for multiple network applications in corresponding order.
The higher priority upstream packet will cause the higher priority downstream packet.
• If there are no packets being sent from high-priority applications, the full transmission rate of the Internet connection is available for lowpriority packets.
6. Set the highest priority packet. To ensure a smooth online gaming experience, you can set ACK, SYN, and ICMP as the highest priority packet.
NOTE: Ensure to enable QoS first and set up the upload and download rate limits.
