QoS Default Policy
Select the options for your QoS default policy. Alternatively, you can define your entire QoS policy through
the Access Policy > QoS Policy page by clearing all of the checkboxes on this page.
n
Ensure low latency priority for delay sensitive services (e.g. VoIP) - Select this option to make sure
that traffic that is very sensitive to delay is prioritized. For example, IP telephony, videoconferencing,
and interactive protocols that must have a short response time, such as Telnet.
Click the delay sensitive services link to see the default services included and add new ones or
remove existing if necessary. QoS tries to send these packets before other packets. This option adds
a rule to the QoS Policy Rule Base.
n
Guarantee X% of the bandwidth to VPN traffic on All services - Select this option to guarantee a
minimum bandwidth for the specified traffic on all services or selected services.
Enter the bandwidth percentage, change the type of traffic if needed, and if necessary click the All
services link to edit a list of selected guaranteed services. This option adds a rule to the QoS Policy
Rule Base.
n
Limit bandwidth consuming applications - Select this option to configure applications, for which you
want to enforce a limit. Applications that use a lot of bandwidth can decrease performance necessary
for important business applications.
Click the bandwidth consuming applications link to see the default applications/categories included,
add new ones, or remove existing, if necessary.
Select Download and/or Upload to configure the maximum bandwidth in each of the selected
options.
You can also configure these applications limits in the:
