Quality of Service (QoS) Setup Guide
(NB604)

NB604 and Quality of Service (QoS)
The following Quality of Service (QoS) settings offer a basic setup example, setting up 2 devices connecting to an
NB604 router, one with the highest priority QoS priority data traffic and the other with the lowest priority QoS priority
data traffic flow. All other data packet traffic through the router assumes a default best effort setting.
Quality of Service refers to the reservation of bandwidth resources on the NB604 router to provide different priorities
to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.
In this implementation Quality of Service employs DSCP –Differentiated Services Code Point –a computer networking
architecture that specifies a simple, scalable and coarse-grained mechanism for classifying, managing network traffic.
This example guide sets up QoS with two devices (PC and laptop) connecting via ethernet cable to an NB604 router.
One device (PC) is assigned high priority traffic while the other device (laptop) is assigned a low priority. Before
Quality of Service can be implemented the first step involves reserving an IP address for each device linking the MAC
address of each device to each IP address.

Quality of Service (QoS) Setup: Part 1 Reserve IP addresses
It is necessary to reserve an IP address for a device that is connecting to the NB604 router so that the QoS settings
can manage each device and set data packet traffic priority by MAC and IP address.
1. Navigate to http://192.168.1.1 in a web browser.
2. Enter 'admin' (without quotes) for both the username and password and click Ok.
3. Select Advanced > LAN > IPv4 Autoconfig.
4. Click the Add Entries button.

5. Enter the MAC address of the computer/device you are connecting to the router. The MAC address is a 12
character set of numbers and letters (A-F), with every 2 characters separated by a colon.
6. Enter the IP address of the computer/device. This is the local address in the range of 192.168.1.x where x = 2
to 254.
7. Click the Apply/Save button.
8. Complete steps 4 through 7 for each device connected to the NB604 router. Each entry will be listed in the
Static IP Lease List as shown below.

Quality of Service (QoS) Setup: Part 2 QoS Configuration Settings
The following guide shows how to setup 2 devices to an NB604 router, one with high priority QoS, one with low
priority QoS.
9. Select Advanced Setup > Quality of Service
10. Check the “Enable QoS” checkbox.
11. Select the Default DSCP Mark as default(000000).
12. Click the Apply/Save button.

High Priority QoS Queue Configuration
13. Select Advanced > Quality of Service > Queue Config.
14. Click the Add button.
15. Enter a name of 15 characters or less to reflect the device will use high priority QoS –eg. PC1HighPriority
16. Set Enable to “Enable”.
17. Set the Interface (Australian customers use atm0(0_8_35), NZ customers use atm0(0_0_100)).
18. Enter a Precedence. For the highest priority set it to 1. For the lowest priority use 3.
19. Set the DSL Latency as Path0.
20. Click the Apply/Save button.

Low Priority QoS Queue Configuration
21. Select Advanced > Quality of Service > Queue Config.
22. Click the Add button.
23. Enter a name of 15 characters or less to reflect the device will use low priority QoS –eg. PC2LowPriority.
24. Set Enable to “Enable”.
25. Set the Interface (Australian customers use atm0(0_8_35), NZ customers use atm0(0_0_100)).
26. Enter a Precedence. For the lowest priority set it to 3. For the highest priority use 1.
27. Set the DSL Latency as Path0.
28. Click the Apply/Save button.

High Priority QoS Classification
29. Select Advanced > Quality of Service > QoS Classification.
30. Click the Add button.

31. Enter a Traffic Class Name reflecting the High Priority QoS rule; eg. PC1HighPriority.
32. Leave the Rule Order as Last.
33. Set the Rule Status to Enable.
34. Set the Class Interface according to how the device connects to the router. In the example above LAN is
selected. Other options are Wireless, Local and USB.
35. Set the Ether Type to IP(0x800). Other options include ARP(0x8086), Ipv6(0x86DD),
PPPoE_DISC(0x8863), 8865(0x8865), 8866(0x8866), 8021Q(0x8100).
36. Enter the Source MAC Address of the device, the unique 12 character signature with every 2 characters
separated by a colon(:), that you previously entered to reserve the device's IP address.
37. Enter the Source IP Address of the device that you previously entered into the Static IP Lease List, in the
range of 192.168.1.x In the example above the IP address is 192.168.1.5.
38. Enter a Destination MAC Address if the connection is to a single device. This is useful for VPN connections.
If you wish the destination MAC address to be any address leave the field blank.
39. Enter a Destination IP Address if the connection is to a single device. This is useful for VPN connections. If
you wish the destination IP address to be any address leave the field blank.
40. Enter a Destination Subnet Mask if you have entered a Destination MAC address and Destination IP
address. This would normally be 255.255.255.0 unless your system administrator advises otherwise. If you
have not entered a Destination MAC or IP address leave the field blank.
41. Set the Differentiated Service Code Point (DSCP) Check to EF(101110).
42. Set the Protocol to TCP. Other options include UDP, ICMP or IGMP.
43. Set “Assign Classification Queue” to Priority 1 (in the example above pppoa0&atm0&Path0&Key38&Pre1).
Other options or priority 2 and 3. Priority 1 gives the highest priority with priority 3 being the lowest.
44. Set Mark Differentiated Service Code Point (DSCP) as EF(101110).
45. Set Mark 802.1p Priority as 5. In the scale 0-7, 0 is best effort, 6 and 7 are reserved for networking
performance so set 5 as the highest priority.
46. Click the Apply/Save button.

Low Priority QoS Classification
47. Select Advanced > Quality of Service > QoS Classification.
48. Click the Add button.
49. Enter a Traffic Class Name reflecting the High Priority QoS rule; eg. PC2LowPriority.
