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.
