8.3.1
Adding a QoS Queue
Click the edit icon in the
Queue Setup
screen to configure a queue.
Figure 81
Queue Setup: Edit
The following table describes the labels in this screen.
Rate Limit
This shows the maximum transmission rate allowed for traffic on this queue.
Modify
Click the
Edit
icon to edit the queue.
Click the
Delete
icon to delete an existing queue. Note that subsequent rules move up by one
when you take this action.

Queue Setup: Edit
LABEL
DESCRIPTION
Active
Select to enable or disable this queue.
Name
Enter the descriptive name of this queue.
Interface
Select the interface to which this queue is applied.
This field is read-only if you are editing the queue.
Priority
Select the priority level (from 1 to 3) of this queue.
The smaller the number, the higher the priority level. Traffic assigned to higher priority
queues gets through faster while traffic in lower priority queues is dropped if the network is
congested.
Weight
Select the weight (from 1 to 8) of this queue.
If two queues have the same priority level, the Device divides the bandwidth across the
queues according to their weights. Queues with larger weights get more bandwidth than
queues with smaller weights.
Rate Limit
Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue.
OK
Click
OK
to save your changes.
Cancel
Click
Cancel
to exit this screen without saving.

The Class Setup Screen
Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into data flows
according to specific criteria such as the source address, destination address, source port number,
destination port number or incoming interface. For example, you can configure a classifier to select
traffic from the same protocol port (such as Telnet) to form a flow.
You can give different priorities to traffic that the Device forwards out through the WAN interface.
Give high priority to voice and video to make them run more smoothly. Similarly, give low priority
to many large file downloads so that they do not reduce the quality of other applications.

DESCRIPTION
Add new Classifier
Click
this to create a new classifier.
Index
This is the index number of the entry.
Status
This field displays whether the classifier is active or not. A yellow bulb signifies that this
classifier is active. A gray bulb signifies that this classifier is not active.
From Interface
This shows the interface from which traffic of this class should come.
Classification
Criteria
This shows criteria specified in this classifier, for example the type and the source MAC
address of traffic that matches this classifier.
DSCP (Traffic
Class) Mark
This is the DSCP number added to traffic of this classifier.
802.1P/1Q Mark
This is the IEEE 802.1p priority level and 802.1Q VLAN tag assigned to traffic of this
classifier.
To Queue
This is the name of the queue in which traffic of this classifier is put.
Modify
Click the
Edit
icon to edit the classifier.
Click the
Delete
icon to delete an existing classifier. Note that subsequent rules move up

QoS > Class Setup Add/Edit
LABEL
DESCRIPTION
Rule Index
Select the rule’s index number from the drop-down list box. This field is available only
when you are adding a new QoS class.
Class Configuration
Active
Use this field to enable or disable the QoS class rule.
Ether Type
Select a predefined application to configure a class for the matched traffic.
If you select
IPv4 or IPv6
, you also need to configure source or destination IP address,
MAC address, DHCP options, DSCP value or the protocol type.
If you select
ARP
, you also need to configure source or destination MAC address.
If you select
802.1Q
, you can configure an 802.1p priority level and VLAN ID.
Interface
Select an interface if you want to classify the traffic received by it.
To Queue
Select a queue that applies to this class.
You should have configured a queue in the
Queue Setup
screen already.
Criteria Configuration
Basic
From
Interface
If you select
From LAN
in the
Interface
field, you can select specific interface(s) from
which traffic is received.
ra0
~
ra3
means wireless interfaces WLAN0 to WLAN3.
If you select
From WAN
in the
Interface
field, you can select a specific WAN connection
(PVC0~PVC2) from which traffic is received.
Source
IP Address
Select the check box and enter the source IP address in dotted decimal notation. A blank
IP address means any source IP address.
Subnet
Netmask/
Source Prefix
Length
Enter the source subnet mask if you select
IPv4
as the
Ether Type
.
Enter the source prefix length if you select
IPv6
as the
Ether Type
.
Port Range
If you select
TCP/UDP
,
TCP
or
UDP
in the
IP protocol
field, select the check box and
enter the port number(s) of the source.
MAC Address
Select the check box and enter the source MAC address of the packet.
Mac Netmask
Type the mask for the specified MAC address to determine which bits a packet’s MAC
address should match.
Enter “f” for each bit of the specified source MAC address that the traffic’s MAC address
should match. Enter “0” for the bit(s) of the matched traffic’s MAC address, which can be
of any hexadecimal character(s). For example, if you set the MAC address to
00:13:49:00:00:00 and the mask to ff:ff:ff:00:00:00, a packet with a MAC address of
00:13:49:12:34:56 matches this criteria.
Exclude
Select this option to exclude the packets that match the specified criteria from this
classifier.
Destination
IP Address
Select the check box and enter the source IP address in dotted decimal notation. A blank
IP address means any destination IP address.
Subnet
