Group 
Name Display the group name. You may modify it if necessary. 
Rate  When the data flow is large, this value shows that the minimum 
bandwidth that this group can share. Its value range is between 1 
and Ceil.  
Ceil  When the data flow is small, this value shows that the maximum 
bandwidth that this group can share. Its value is between 1 and 
100. 
 
  Add a QoS Rule 
Click the Add button on the Quality of Service Settings page, and the following 
page appears. 
 
 
The parameters on this page are described as follows: 
Field Description 
Name  Set the rule name. 
Group  Select the group that the rule belongs to.  
						

							 
47 
MAC 
Address The source MAC address of the rule. If data packets include the 
MAC address, the data packets are placed into the group. 
Dest. IP 
address The destination IP address of the rule. If data packets include the 
IP address, the data packets are placed into the group. 
Src. IP 
address The source IP address of the rule. If data packets include the IP 
address, the data packets are placed into the group. 
Packet 
Length The packet length of the rule. If data packets match the packet 
length, the data packets are placed into the group. 
DSCP  The DSCP mark. If data packets include the DSCP, the data 
packets are placed into the group. 
Protocol  The protocol types include TCP, UDP, ICMP, and Application. If 
data packets match the protocol, the data packets are placed into 
the group. When selecting TCP or UDP, you need to set Src Port 
and Src Port Range. When selecting Application, you may select 
a proper protocol in the drop down list. 
Remark 
DSCP 
as If data packets match the parameters above, you can determine 
whether to remark DSCP. The default setting is Auto. 
 
After finishing the settings, click the Add button to add the new rule. 
  Delete a QoS Rule 
If there are QoS rules in the QoS rule table, and you want to delete a QoS rule, you 
can select the rule, and then click the Delete button to delete this rule. 
 
  Load Default Settings 
Click the Load Default button on the Quality of Service Settings page, system will 
load the default QoS rules. See the following figure:  
						

							 
48 
 
 
After loading the default rules, the four groups are redefined as High, Middle, 
Default, and Low, and the minimum bandwidth values of the corresponding groups 
are changed as 30%, 20%, 5%, and 10%. You can also delete the default rules if

necessary. 
  The examples of QoS Settings 
- Set the Upload Bandwidth 
 
 
On the Quality of Service Settings page, enable the QoS, and set the upload 
bandwidth. For example, set the value of upload bandwidth to be 2Mbps. 
After finishing the settings, click the Submit button to submit the settings and the 
following page appears.   
 
- Modify a Group Attribute  
						

							 
50 
After enabling QoS, system establishes 4 groups. Click the Modify button of the 
corresponding group, and you can modify the attribute settings of the corresponding 
group. Let’s take High group as an example. 
 
 
On this page, set the Rate value to be 30. If the upload bandwidth is 2Mbps, when the 
data flow is large, it indicates that the minimum bandwidth that High group can share 
is 30% of the total bandwidth, that is, 06 Mbps. When the data flow is little, the 
maximum bandwidth that High group can share is 100% of the total bandwidth, that is, 
2Mbps. 
- Add a QoS Rule 
Click the Add button on the Quality of Service Settings page to display the 
Classifier Settings page. 
 
On this page, you can add a QoS group. For example, set the name to be Example1, 
add it to the High group, and select the ICMP protocol.

After finishing the settings, click the Add button and the following page appears.   
 
 
  About DSCP 
DSCP consists of 6 bits of IP packet header. It uses ToS field. This byte is also called 
DSCP byte. Its position among the byte is as follows: 
DS5 DS4 DS3 DS2 DS1 DS0 CU CU 
DSCP priority: 6 bits (DS5-DS0) 
Unused (CU): 2 bits 
The values of DSCP priority are 64 (0~63). 0 is the lowest priority level, and the 63 is 
the highest priority level. In fact, DSCP field is the superset of the IP priority field. 
DSCP field is backward compatible with the IP priority. At present, the defined default 
DSCP is 0. Class selector DSCP is backward compatible with the IP priority. The 
values are 8, 16, 24, 32, 40, 48, and 56. Usually, EF (Expedited Forwarding) is used 
for low delay service and the recommended value is 46 (101110).
 AF (assured 
forwarding) defines 4 service levels, and each service level includes three 
descending levels. The following table shows the concrete values as follows:   
Service level 
priority Ty p e  1Ty p e  2  Ty p e  3  Ty p e  4  
Low discarding priority AF11 = 
10 AF21 = 18  AF31 = 26  AF41 = 34 
Medium discarding 
priority AF12 = 
12 AF22 = 20  AF32 = 28  AF42 = 36 
High discarding priority AF13 = 
14 AF23 = 22  AF33 = 30  AF43 = 38
