Use this screen to enable or disable QoS, and select a DSCP mark to use on all
outgoing packets that do not match a QoS classification rule.

DESCRIPTION
Enable QoS
Select the check box to turn on QoS to improve your network performance.
You can give priority 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.
Select
Default
DSCP Mark
Select a DSCP mark to use on all outgoing packets that do not match a QoS
classification rule. You can select a specific DSCP mark to use or have the
ZyXEL Device automatically select a DSCP mark to use.
Save/Apply
Click this button to save the changes and have the ZyXEL Device start using
them.

following screen. This screen lists the QoS queues. A QoS queue sets the priority
used for incoming packets that the QoS classifier has grouped into a flow.

Interface name
This field displays to which interface the queue applies. If it is a WAN
connection, the WAN connection’s DSL port, Virtual Path Identifier,

Description
This field displays any extra configured identification information.
Precedence
This shows the queue’s priority relative to the other queues. The lower
the number, the higher the priority.
Queue Key
This is the queue entry’s index number.

Click this button to go to a screen where you can configure settings for
a new QoS queue.

the following screen. Use this screen to configure a QoS queue. A QoS queue sets
the priority used for incoming packets that the QoS classifier has grouped into a
flow.
Note: You can only add QoS queues for WAN interfaces that have QoS enabled.

QoS Classification
to open the
following screen.
This screen lists the QoS classifiers. A classifier groups upstream 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. The classifier also assigns a specific QoS
queue, DSCP mark, and/or IEEE 802.1p tag.

The following table describes the labels in this screen.
Table 38
Advanced > Quality of Service > QoS Classification
LABEL
DESCRIPTION
Class Name
This is the name of the classifier.
MARK
These columns are the QoS setting the ZyXEL Device uses for or
assigns to the packets of upstream traffic that match this QoS
classifier.
DSCP Mark
This is the DSCP mark the ZyXEL Device assigns to the packets of
upstream traffic that match this QoS classifier.
Queue ID
This is the QoS queue the ZyXEL Device uses for the packets of
upstream traffic that match this QoS classifier.
802.1P Mark
This is the IEEE 802.1p mark the ZyXEL Device assigns to the packets
of upstream traffic that match this QoS classifier.
TRAFFIC
CLASSIFICATION
RULES
These columns identify the upstream traffic to which the QoS classifier
applies.
Lan Port
This is the source Ethernet port of the traffic.
Protocol
This is the type of packets.
DSCP
This is the DSCP mark.
Source Addr./
Mask
This is the IP address (and optionally the subnet mask) of the device
that sent the traffic.
Source Port
This is the port number that a device used to send the traffic.

Set-1 is based on different fields within the TCP/UDP/IP layer plus the physical
Dest. Addr./Mask
This is the IP address (and optionally the subnet mask) of the device
that the traffic is going to.
Dest. Port
This is the port number on a device to which the traffic is going.
Source MAC
Addr./Mask
This is the MAC address (and optionally the subnet mask) of the
device that sent the traffic.
Dest. MAC Addr./
Mask
This is the MAC address (and optionally the subnet mask) of the
device that the traffic is going to.
802.1P
This is the IEEE 802.1p mark on the traffic.
Order
This is the classifier’s place in the classifiers list.
Enable / Disable
The classifier is active when this check box is selected.
Remove
To remove an entry, select its
Remove
check box and click the
Remove
button.
Add
Click this button to go to a screen where you can configure settings for
a new QoS queue.
