Classification
Order
Select an existing number for where you want to put this classifier to
move the classifier to the number you selected after clicking
Apply
.
Select
Last
to put this rule in the back of the classifier list.
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.
If you select
8021Q
, you can configure an 802.1p priority level and
VLAN ID in the
Others
section.
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.

QoS Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
10.6.1
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to
identify the VLAN membership of a frame across bridges. A VLAN tag includes the
12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a
specific VLAN and provides the information that devices need to process the frame
across the network.
IEEE 802.1p specifies the user priority field and defines up to eight separate traffic
types. The following table describes the traffic types defined in the IEEE 802.1d
standard (which incorporates the 802.1p).

IEEE 802.1p Priority Level and Traffic Type
PRIORITY
LEVEL

Level 7
Typically used for network control traffic such as router configuration
messages.
Level 6
Typically used for voice traffic that is especially sensitive to jitter (jitter is the
variations in delay).

10.6.2
IP Precedence
Similar to IEEE 802.1p prioritization at layer-2, you can use IP precedence to
prioritize packets in a layer-3 network. IP precedence uses three bits of the eight-
bit ToS (Type of Service) field in the IP header. There are eight classes of services
(ranging from zero to seven) in IP precedence. Zero is the lowest priority level and
seven is the highest.
10.6.3
DiffServ
QoS is used to prioritize source-to-destination traffic flows. All packets in the flow
are given the same priority. You can use CoS (class of service) to give different
priorities to different packet types.
DiffServ (Differentiated Services) is a class of service (CoS) model that marks
packets so that they receive specific per-hop treatment at DiffServ-compliant
network devices along the route based on the application types and traffic flow.
Packets are marked with DiffServ Code Points (DSCPs) indicating the level of
service desired. This allows the intermediary DiffServ-compliant network devices
to handle the packets differently depending on the code points without the need to
negotiate paths or remember state information for every flow. In addition,
applications do not have to request a particular service or give advanced notice of
where the traffic is going.
DSCP and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of
Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and
a 6-bit DSCP field which can define up to 64 service levels. The following figure
illustrates the DS field.
Level 5
Typically used for video that consumes high bandwidth and is sensitive to
jitter.
Level 4
Typically used for controlled load, latency-sensitive traffic such as SNA
(Systems Network Architecture) transactions.
Level 3
Typically used for “excellent effort” or better than best effort and would
include important business traffic that can tolerate some delay.
Level 2
This is for “spare bandwidth”.
Level 1
This is typically used for non-critical “background” traffic such as bulk
transfers that are allowed but that should not affect other applications and
users.
Level 0
Typically used for best-effort traffic.
