5.3.6 Configuring 802.1p Priority Values
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 (0-7), where level 7 is the highest one. In
addition, iPECS SBG-1000 maps these eight levels to priority queues, where Queue 0 has the
lowest priority.
iPECS SBG-1000’s QoS supports up to four queues. By default, the higher the level and queue
values, the more priority they receive. Therefore, the more critical the traffic is, the higher priority
level and queue number it should receive. To change the mapping between a priority value and a
queue value, perform the following:
1. Under the ‘QoS’ menu item, click ‘802.1p Settings’. The following screen appears.

2. From the corresponding drop-down menu, select a desired value.
3. Click ‘OK’ to save the settings.
5.3.7 Viewing Traffic Statistics
iPECS SBG-1000 provides you with accurate, real-time information on the traffic moving through
your defined device classes. For example, the amount of packets sent, dropped or delayed, are
just a few of the parameters that you can monitor per each shaping class. To view your class
statistics, click ‘Class Statistics’ under the QoS menu item. The following screen appears.
