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

DESCRIPTION
Active
Select to enable or disable this queue.
Name
Enter the descriptive name of this queue.
Interface
This shows the name of the ZyXEL Device’s interface through which traffic
in this queue passes.
Priority
Select the priority level (from 1 to 7) of this queue.
The larger 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 15) of this queue.
If two queues have the same priority level, the ZyXEL 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.

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 ZyXEL 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.

Forward to
Interface
Select a WAN interface through which traffic of this class will be
forwarded out. If you select
Unchange
, the ZyXEL Device forward
traffic of this class according to the default routing table.
DSCP Mark
This field is available only when you select the
Ether Type
check box
in
Criteria Configuration-Basic
section.
If you select
Mark
, enter a DSCP value with which the ZyXEL Device
replaces the DSCP field in the packets.
If you select
Unchange
, the ZyXEL Device keep the DSCP field in the
packets.
To Queue
Select a queue that applies to this class.
You should have configured a queue in the
Queue Setup
screen
already.
Criteria Configuration
Use the following fields to configure the criteria for traffic classification.
Basic
From Interface
Select whether the traffic class comes from the LAN or a wireless
interface.
Ether Type
Select a predefined application to configure a class for the matched
traffic.
If you select
IP
, you also need to configure source or destination MAC
address, IP address, DHCP options, DSCP value or the protocol type.
Source
MAC Address
Select the check box and enter the source MAC address of the packet.
MAC Mask
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.
IP Address
Select the check box and enter the source IP address in dotted
decimal notation. A blank source IP address means any source IP
address.
IP Subnet
Mask
Enter the source subnet mask.
Port Range
If you select
TCP
or
UDP
in the
IP Protocol
field, select the check
box and enter the port number(s) of the source.
Exclude
Select this option to exclude the packets that match the specified
criteria from this classifier.

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.

decimal notation. A blank source IP address means any source IP
address.
