5.8.2. CONFIGURING A LAYER TWO INTERFACE
Generally these will have been configured before in the layer two interfaces settings.
It’s possible to configure an Ethernet interface from the QoS menu, but to configure an ATM interface
this must have been previously configured from the Layer Two menu option.
When configuring the layer two parameters for an interface select the menu options to configure the
IP QoS Schedules for the interface. These options are
Strict Priority
Precedence of the default queue Default 8 (lowest)
Weighted fair queuing
Weighted fair value of the default queue [1-63] 1
MPAAL Group precedence 1 to 8
5.8.3. QOS – QUEUE MANAGEMENT CONFIGURATION
If Enable the QoS checkbox is selected, choose a default DSCP mark to automatically mark
incoming traffic without reference to a particular classifier. Click 'Apply/Save' button to save
it.
Note: If Enable QoS checkbox is not selected, QoS will be disabled for all interfaces.
Note: The default DSCP mark is used to mark all egress packets that do not match any
classification rules.
Enable QoS
If you enable QoS (tick box) you are presented with another menu option, and a drop down box where
you can select your DSCP Mark.
Select Default DSCP Mark
Note: A default DSCP mark is used to mark all ‘egress’ packets that do not match any classification rules.
Enabling QoS then allows selection of the DSCP values from the drop down menu, which displays the
following options. Note’ No-Change (-1) and Auto Marking (-2) options are also displayed.
