8-3: Add Traffic Priority Rule - Parameter Descriptions
Parameter
Description
Matching
Use the parameters in this screen section to apply
a rule. To apply the rule, matching must be
performed between IP addresses and/or a traffic
protocol must be defined. From the drop-down list
choose 'Any', 'User Defined' or the host.
Source Address
The source address of the packets. From the drop-
down list choose 'Any', 'User Defined' or the host.
Destination Address
The destination address of the packets. From the
drop-down list choose 'Any', 'User Defined' or the
host.
Protocol
From the drop-down list, choose a specific
protocol, or add a new one by choosing 'User
Defined'; the screen 'Edit Service' opens. Click the
icon 'new' under the column 'Action'; this
commences a sequence that adds a new protocol.
QoS Operation
In this screen section, set a Quality of Service
working method. Check parameter 'Set Priority' or
'Set DSCP' (refer to the descriptions below).
Set Priority
Check this check box to add a priority to the rule.
Select priority level 0-7 where 0 = lowest and 7 =
highest (each priority level is mapped to
low/medium/high priority). This sets the priority of a
packet on the connection matching the rule, while
routing the packet.
Set DSCP
Check this check box to mark a DSCP value on
packets matching this rule. Enter a value between
0-63 in the field that appears.
Log Packets Matched by This Rule
Under the screen section 'Logging', this check box
must be checked in order to log the first packet
from a connection that was matched by this rule.
Schedule
'Always' or 'User Defined'. By default, the rule will
always be active. However, you can configure
scheduler rules in order to define time segments
during which the rule may be active.
Note:
The hierarchy of the class rules is determined by the order of their addition to
the class. For example, if your first rule is 'match packets with any source
address, any destination address, and any protocol to this class; then all
packets traveling through the gateway will be associated with the specific
class. Any rules defined later will not have any effect.
