When QoS Control Mode = Min/Max:
When QoS Control Mode = Pri-Weighted:
•
Add a Rule – Enter your desired parameters as needed, and click [Add Rule] to add the rule
to the Per Group QoS Rule table. Upon entry, the table index automatically increments to
the next available number. Note the following (from left to right):
Column
Name
VLAN Min
VLAN Max
TOS
Application
Src IP/Msk
Dst IP/Msk
Min Src Port
Max Src Prt
Min Dst Port
Max Dst Port
Priority
Weight
Min BW
Description
This is the name assigned to the group rule. The name you create must be 20 characters
or less, and it must be unique across all groups.
Enter a single VLAN ID as the minimum filter value. .
Enter a single VLAN ID as the maximum filter value.
Type Of Service bits include a six-bit Differentiated Services Code Point (DSCP) and a
two-bit Explicit Congestion Notification (ECN) field:
• Enter an explicit Code Point match.
• Enter the wildcard entry of 255 so that all values trigger true.
Use the drop-down list to select the application as UDP, TCP, ICMP, RTP, RTP-VOICE,
RTP-VIDEO, RTPS, FTP, HTTP, TELNET, SMTP, SNMP, or All-IP.
Enter a Source IP Address/Mask in the form XXX.XXX.XXX.XXX/YY.
Enter a Destination IP Address/Mask in the form XXX.XXX.XXX.XXX/YY.
You should specify the Min / Max Source / Destination Ports only if you are aware of
the port usage of the desired protocol or application. There are well-known ports for
various protocols, but often only the 'command' messaging is transacted on these ports
and the 'data' is transferred through a negotiated port.
(Max/Pri and Pri-Weighted modes only) Use the drop-down list to assign a Priority Level
from 1 to 8 for each flow:
• The IP Module classifies each packet that is to be forwarded over the satellite; the
packet then has a Priority assigned according to the defined QoS Rules;
• Any latency critical traffic such as VoIP/RTP should always be assigned Priority 1;
• Priority 1 packets are forwarded immediately; Priority 2 packets are forwarded as soon
as there are no Priority 1 packets in the Queue; and so on;
• Any packet that does not meet a QoS Rule is assigned to the Default Rule and is
assigned a Priority of 9.
(Pri-Weighted mode only) Enter a weight from 1 to 9. Weighting is used to drain traffic
having the same Priority Level ("Max/Pri" mode) after the minimum bandwidth is met ("Min
BW"). The larger the number, the higher the weight.
(Min/Max and Pri-Weighted modes only) Assign a value to limit the flow to this minimum
utilized bandwidth; otherwise, you may select the default of no bandwidth restriction.
