QoS Queue Configuration
The queuing in packet QoS becomes effective only when packet is
forwarded to QoS-enabled PVC. Packet forwarding is determined
by IP routing or bridging, not under control of the packet QoS.
Select
Advanced Setup
>
Queue Config
. In this page, you can
configure QoS queue. A maximum of 24 entries can be configured.
QoS Queue Configuration can allocate four queues. Each of the
queues can be configured for a precedence value (Lower integer
values for precedence imply higher priority for this queue relative
to others). The queue entry configured is used by the classifier to
place ingress packets appropriately.
Note:
Lower integer values for precedence imply higher priority for
this queue relative to others. For example, add a QoS queue entry
and allocate it to a specific network interface (PVC 0/0/35). Set
integer values for queue precedence to 1.

Step 1
This page allows you to configure a QoS queue entry and then
assign it a specific network interface.
Queue Configuration Status:
Set to enable or disable a QoS
queue.
Queue:
Select a specific network interface. When you have already
selected a network interface, the specific network interface selected
automatically allocates to the queue.
Queue Precedence:
Select an integer value for queue precedence.
After you select an integer value, the queue entry appropriately
places to ingress packets. Lower integer values for precedence
imply higher priority for this queue relative to others.
Click
Save/Apply
to save and activate the filter.
After the queue is configured, you can create several traffic class
rules to classify the upstream traffic.

QoS Classification
Some applications require specific bandwidth to ensure its data be forwarded in time. QoS classification can creates
traffic class rule to classify the upstream traffic. Assign queue which defines the precedence and the interface and
optionally overwrite the IP header DSCP byte. After QoS classification, QoS divides capacity between different
applications and provides undelayed, continuous data transfer where data packet with higher priority is given
preference. The follow figure shows QoS classification.

QoS Classification
. In this page, you
can configure network traffic classes.
Click
Add
to create a traffic class rule to classify the upstream
traffic.
Traffic Class Name:
Enter a name of the class.
Rule Order:
Select order for queue.
Rule Status:
Enable or disable this traffic class rule.
Assign Classification Queue:
Select a classification queue.
Assign Differentiated Service Code Point (DSCP) Mark:
Select a mark service that modifies the original packet IP header
if all rules defined within the classification class are matched.
(CS-Mark IP Precedence, AF-Assured Forwarding, EF-Expedited
Forwarding)
Mark 802.1p if 802.1q is Enabled:
Select an 802.1p priority
number that serves as the 802.1p value.
There are two sets of classification rules.
Set-1
is based on
different fields within TCP/UDP/IP layer plus physical LAN port;
Set-2
is based on IEEE 802.1p priority field.

Set-1
rules contain the following:
Physical LAN Port: Select one among USB port, Ethernet ports and
wireless port.
Protocol: Select one among TCP/UDP TCP UDP or ICMP
protocols.
Source IP Address
Source subnet mask
UPD/TCP Source Port
Destination IP Address
Destination Subnet Mask
UPD/TCP destination port or a range of ports
Source Mac Address
Source Mac Mask
Destination Mac Address
Destination Mac Mask
Set-2
rules contain the following:
802.1p Priority: the 802.1p header includes a 3-bit prioritization
field, which allows packets to be grouped into eight levels of priority
(0-7), where level 7 is the highest one.
