Differentiated Service Code Point (DSCP) Settings
If you click the
Quality of Service
link in the
Advanced
screen and then click
DSCP Settings
in the left submenu,
the following screen will appear.
Familiarity with the Differentiated Services model is essential to understanding DSCP. Differentiated Services
(Diffserv) is a Class of Service (CoS) model that enhances best-effort Internet services by differentiating traffic by
users, service requirements, and other criteria. Packets are specifically marked, allowing network nodes to provide
different levels of service, as appropriate for voice calls, video playback, or other delay-sensitive applications, via
priority queuing or bandwidth allocation, or by choosing dedicated routes for specific traffic flows.
Diffserv defines a field in IP packet headers referred to as the Differentiated Services Codepoint (DSCP). Hosts or
routers passing traffic to a Diffserv-enabled network will typically mark each transmitted packet with an appropriate
DSCP. The DSCP markings are used by Diffserv network routers to appropriately classify packets and to apply a
particular queue handling or scheduling behavior to packets.
The Router provides a table of predefined DSCP values, which are mapped to 802.1p priority marking method. Any
of the existing DSCP setting can be edited or deleted, and new entries can be added. To add a new DSCP value,
press the
New Entry
link at the bottom of this screen.

802.1P Settings
If you click the
Quality of Service
link in the
Advanced
screen and then click
802.1P Settings
in the left submenu,
the following screen will appear.
The IEEE 802.1p priority marking method is a standard for prioritizing network traffic at the data link/Mac sub-
layer. 802.1p traffic is simply classified and sent to the destination, with no bandwidth reservations established.
The 802.1p header includes a 3-bit prioritization field, which allows packets to be grouped into eight levels of
priority. By default, the highest priority is seven, which might be assigned to network-critical traffic. Values five and
six may be applied to delay-sensitive applications such as interactive video and voice. Data classes four through one
range from controlled-load applications down to “loss eligible” traffic. Zero is the value for unassigned traffic and is
used as a best effort default, invoked automatically when no other value has been set.
A packet can match more than one rule. This means the following:
•
The first class rule has precedence over all other class rules (scanning is stopped once the first rule is
reached).
•
The first traffic-priority (classless) rule has precedence over all other traffic priority rules.
•
There is no prevention of a traffic-priority rule conflicting with a class rule. In this case, the priority and
DSCP setting of the class rule (if given) will take precedence.
Select the desired values from the drop-down lists, and then click
Apply
to save the settings.

Class Statistics
If you click the
Quality of Service
link in the
Advanced
screen and then click
Class Statistics
in the left submenu,
the following screen will appear.
The Router provides accurate, real-time information on the traffic moving through the defined device classes. For
example, the amount of packets sent, dropped, or delayed are just a few of the parameters monitored per each
shaping class.
NOTE:
Class statistics will be available only after defining at least one class (otherwise the screen will not display
any values).
If you do not want the screen to refresh automatically, click
Automatic Refresh Off.

Remote Administration
link, the following
screen will appear.
It is possible to access and control your Router not only from within the home network, but also from the Internet.
This allows you to view or change settings while traveling. It also enables you to allow Verizon to change settings or
help you troubleshoot functionality or communication issues from a remote location. Remote access to your Router
is blocked by default to ensure the security of your network. However, your Router supports the following services,
and you may use the Remote Administration Security screen to selectively enable these services if they are needed.
WARNING:
With Remote Administration enabled, your network will be at risk from outside attacks.
To configure Remote Administration, enter the appropriate settings, and then click
Apply
to save the settings.
NOTE:
This Router ships with Telnet disabled.
