To access the Policy Flow Form, select QoS -> Packet Flow. Table 6-13 describes the fields. Figure 6-81 shows an example
QoS Policy Flow Form.
TABLE 6-13 Options for the QoS Policy Flow Form
Option Purpose
Target
Device
Classes
The device classes to be included in this Flow.
Set Targets Brings up the Edit QOS Device Class List, allowing the user to select any combination of device
classes to include.Press and Hold the SHift key to select more than one device class.
Targets can also be added/removed by clicking the “Target” checkbox.
Device Class
table
Table of the Device Classes, Targets, and a description of the device class. Supported indicates
there are no detected errors.
Flow Name A pull-down of all existing flows.If selected, the parameters of the selected flow appear in the form.
Device Class A pull-down of the device classes that are included in this policy. This reflects the tic boxes chosen
in the Device Class table.
New Flow Brings up the Select New Name window. The user can choose to copy the parameters from the
flow currently displayed.
Copy Saves the parameters from the current Device Class target so they can be 'pasted' to another
target device class by the “translation” feature.
Paste Translates and applies the parameters that were “copied”. If there is no translation for a parameter
it will appear with square brackets around it, and be colored red. If there is similar parameter but
the value cannot be translated the value will be enclosed in square brackets and the entry will again
be colored red.
Flow
Classifiers
A table of the current classifiers. Delete removes the selected classifier. The Up and Down buttons
change the order of classifiers (and so the logical OR), but not the selection.
Classifier # The number of the classifier in the list. The order determines the precedence of the rules
Clear All
Classifiers
Delete all classifiers in the Flow Classifier table and return to the default classifier and value
(ETHFORMAT=ANY).
New
Classifier
Adds a classifier to the Flow Classifier table with the default classifier and value
(ETHFORMAT=ANY). This classifier appears in the Classifier Parameter list and can be modified or
replaced
Classifier
Parameters
A list of the parameters for the selected classifier. If more than one parameter is listed, the Up,
Down, and Delete buttons are active. The Up and Down buttons change the order of classifiers
(and so the logical AND), but the order does not affect the function
Parameter
pull-down
and value
field
A pull-down of the available parameters. As each one is selected, the associated value field appears.
Values may be selected from a list of values, where each element of the list can be a Name, an Ip or
MAC address, an integer range, a fixed point decimal range, or hexadecimal value. One parameter
TCPFLAGS is a list of named values selected with a drop-down menu.
For example, selecting VID will bring up a value field with 500, a default value. The user can then
overwrite this value of 500.

Replace
Parameter
If the parameter is not in the Flow Classifier table, it is added to the parameter list for that classifier
(and creating another AND condition). If the parameter has already been chosen, it replaces what is
already there with the new value.
The available Parameters and Values change as parameters are added, reflecting the
interdependencies between the parameters. For example if TCPDPORT is selected, PROTOCOL
is added with a value of IP and it range is restricted to only IP
