For the “Min/Max” page:
From left to right:
Column Description
Protocol Use the drop-down list to select the Protocol as UDP , TCP , ICMP , RTP , VOICE , VIDEO ,
RTPS , FTP , HTTP , TELNET , SMTP , SNMP , All-IP , Non-IP , or All.
VLAN Range Enter the minimum-to-maximum range of VLAN IDs from 0-4094 (applicable only in
Managed Switch Mode).
TOS Enter the Type of Service.
Src IP/Mask Enter a Source IP Address/Mask in the form XXX.XXX.XXX.XXX/YY.
Dst IP/Mask Enter a Destination IP Address/Mask in the form XXX.XXX.XXX.XXX/YY.
Min/Max Src Port
Selection of Source/Destination Ports should only be done 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.
Min/Max Dst Port
Min BW (Kbps) ( “ Min/Max” page only) Assign a value to a flow to restrict the Minimum Bandwidth that
any particular flow will utilize; otherwise, the default of no bandwidth restriction can be
selected.
Max BW (Kbps) Assign a value to a flow to restrict the Maximum Bandwidth that any particular flow will
utilize; otherwise, the default of no bandwidth restriction can be selected.
Priority (“Max/Priority” page 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.
WRED Use the drop-down list to set WRED (Weighted Random Early Detection) as Disable or
Enable .
Filter All Use the drop-down list to set Filter All to Disable or Enable . QoS allows specific flows to
be designated as ‘filtered’ so the IP Packet Processor card will discard traffic that you do
not want to forward over a satellite link.
For either page , click [Add Rule] to execute the addition of the new rule to the QoS Rules Table.
