7. Click the Add A New Rule button. A new screen to configure a QoS rule is displayed.
8. For the Rule item, check the Enable option. Use the descriptions in the table below to complete the rest of the settings
for the rule. When the Class field is set to TCPPORT, UDPPORT, MAC, TOS or VLANPRI, you are able to add a
conjunction rule. Click the Add A Conjunction (AND) Rule button that appears at the bottom of the page to add a
conjunction rule.

Select to enable or disable the QoS rule.
Select the class of traffic you would like to prioritise. This may be IP, TCP Port, UDP Port, MAC address,
DSCP, ToS or VLAN Priority field.
This field is only displayed when you select the Class field to be IP, TCPPORT, UDPPORT, MAC or VLANPRI.
Enter the appropriate details for the class you have chosen e.g. an IP address, a TCP or UDP port number, a
MAC address or a VLAN Priority flag.
Only displayed when Class is set to IP. Enter the subnet mask of the IP address specified in the Class Info –
IP field.
Use the drop down list to select the protocol to which the rule should apply. This may be TCP, UDP or ICMP.
Use the drop down list to select the DiffServ CodePoint that will be marked in the header of IP packets. There
are 7 IP Precedence classes which are used in Type of Service headers but are also backwards compatible
with DiffServ routers. The IP Precedence codes mark priority traffic. Assured Forwarding (AF) marks are also
available. AF marks assign a drop precedence to each packet which defines the likelihood that a packet is
dropped if traffic exceeds the subscribed rate. The last type of code is the Expedited Forwarding (EF) code.
Packets marked EF have the properties of low delay, low loss and low jitter. This makes EF packets desirable
for real-time streaming services for voice and video.
This field is only displayed when the Class field is set to DSCP. The Service Type field specifies the type of
packets to which the rule should apply. Use the drop down list to select the service type. The TCP/UDP port
numbers are listed in brackets after each item.
The Type of Service field is only displayed when Class is set to TOS. Use the Type of Service drop down list
to specify whether the QoS rule should minimize delay, maximize throughput, maximize reliability, minimize
cost or just provide normal service.
Select the function of the rule. You can select from Priority, Marking, Max Rate, Min Rate, Session, Drop, Log
or Alert.
This field changes depending on the selected function. When Function is set to PRI (Priority), the Function
data field should contain a priority value from 1 to 6 with 1 being the highest priority. When Function is set to
MARKING, the Function data field allows you to specify a DiffServ Code Point marking for the packets. When
the Function field is set to MAXR (Max Rate) or MINR (Minimum Rate), the Function data field should contain
a data transfer rate in either Kilobits per second (KBps) or Megabits per second (MBps). This represents the
minimum or maximum rate that the packet should expect to achieve on the network. When the Function field
is set to SESSION, the Function data field should contain an integer representing the maximum number of
sessions.
Select the direction of traffic to prioritise. Available options include In, Out or Both.
Select a schedule for the new rule to apply. Previously created schedules are visible here or you can select
the rule to always apply.
This field is displayed only when you have selected to add a conjunction rule. A conjunction rule allows you to
add a second set of criteria with which the packets will be marked. Use the drop down list to select a second
class of traffic for the rule. The only classes that will show up are MAC, TCPPORT, UDPPORT, TOS or
VLANPRI.
This field is only displayed when you select to add a conjunction rule. Enter the appropriate details for the
class you have chosen e.g. a MAC address, a TCP or UDP port number, a Type of Service or a VLAN Priority
flag.
