• Set Priority Select this check box if you would like to change a priority of the packets
matching the rule. The screen refreshes (see Figure 5.56), enabling you to select between
one of eight priority levels, zero being the lowest and seven the highest. Each priority level is
assigned a default queue number, where Queue 0 has the lowest priority. iPECS SBG-1000’s
QoS supports up to four queues.
Figure 5.56 Set Priority with Queuing
The matching between a priority level and a queue number can be edited in the ‘802.1p
Settings’ screen (for more information, refer to Section 5.3.6).
• Apply QoS on Select whether to apply QoS on a connection or just the first packet. When
applying on a connection, the data transfer session will be handled using Stateful Packet
Inspection (SPI). This means that other packets matching this rule will be automatically
allowed to access, and the same QoS scheme will be applied to them.
Logging Monitor the rule.
• Log Packets Matched by This Rule Select this check box to log the first packet from a
connection that was matched by this rule.

during which the rule may be active, by selecting ‘User Defined’ from the ‘Schedule’
drop-down menu. If more than one scheduler rule is defined, the ‘Schedule’ drop-down menu
will allow you to choose between the available rules. To learn how to configure scheduler
rules, refer to Section 6.9.3.
3. Click ‘OK’ to save the settings.
The order of the rules’ appearance represents both the order in which they were defined and the
sequence by which they will be applied. You may change this order after your rules are already
defined (without having to delete and then re-add them), by using the action icon and
action icon.
