CDM-840 Remote Router
Ethernet Management
For the "Min/Max" page:
From left to right, note the following:
•
Protocol – Use the drop-down menu to select the Protocol as UDP, TCP, ICMP, RTP,
VOICE, VIDEO, RTPS, FTP, HTTP, TELNET, SMTP, SNMP, All-IP, Non-IP, or
All.
•
Src IP/Mask – Enter a Source IP Address/Mask in the form XXX.XXX.XXX.XXX/YY.
•
Dest IP/Mask – Enter a Destination IP Address/Mask in the form XXX.XXX.XXX.XXX/YY.
•
Min Src Port / Max Src Port / Min Dst Port / Max Dst Port – Selection of
Source/Destination Ports should only be done if the user is 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 BW (Kbps) ("Min/Max" page only) / Max BW (Kbps) – These can be assigned to
a flow to restrict the Minimum/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 menu to assign a Priority level
from 1 to 8 for each flow:
o 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;
o Any latency critical traffic such as VoIP/RTP should always be assigned Priority 1;
o 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;
o 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 menu to set WRED (Weighted Random Early Detection)
as Disable or Enable.
•
Filter All – Use the drop-down menu 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 the user does not want to forward over a satellite link.
Click [Add Route] once all changes have been made to this section for either page.
Delete Rule
This section is identical for both the "Max/Priority" and "Min/Max" pages. Enter Rule to
Delete, then click [Delete Rule] once all changes have been made to this section. The specified
route entry will then be deleted from the route table.
