Figure J-4. Configuration | WAN | QoS Page Example (Control Mode = Off)
Use the CDM-840 HTTP Interface 'Configuration | WAN | QoS' page (Figure J-4) to manage QoS
Groups. In the Add/Change/Delete Group section of the page, use the drop-down list to select
the desired QoS Control Mode: Max/Pri, Min/Max, Pri-Weighted, or DiffServ. Click [Change] to
proceed.
J.2.2.1 QoS Group Max/Pri Control Mode
In Max/Pri Control Mode, you may configure up to 31 QoS rules using VLAN Range, TOS,
Protocol (Application), Source and Destination IP Addresses/Subnets, and Source and
Destination Port range in order to match packets to the desired QoS rule. For each created rule,
you can also set the QoS treatments such as Priority, limiting the Maximum Bandwidth, enable
or disable WRED, and enable or disable the FILTER ALL rule.
When you enable WRED for a specific queue, QoS randomly drops packets after reaching 50% of
the QoS queue capacity.
When you enable the FILTER ALL option for a rule, QoS provides the ability to filter the packet
completely. In other words, all packets matching the QoS Rule with the FILTER ALL option
enabled will be dropped.
For example, using the CDM-840 HTTP Interface 'Configuration | WAN | QoS' page:
1. Select Max/Pri as the QoS Group Control Mode.
2. Set the Modem Tx bandwidth to 2048 kbps.
