f. Click the newly added class name; the following page appears:
Figure 3-74: Defining Shaping Class
g. Configure the following fields:
a. Name: name of the class.
b. Class Priority: priority level of the class, where zero is the highest and
seven the lowest.
c. Bandwidth: reserved transmission bandwidth in kilobits per second. You can
limit the maximum allowed bandwidth by selecting the 'Specify' option and
then define the Kbits/s.
d. Policy: class policy determines the policy of routing packets inside the class:
9 Priority: Priority queuing utilizes multiple queues, so that traffic is
distributed among queues based on priority. This priority is defined
according to packet's priority, which can be defined explicitly, by a
DSCP value, or by a 802.1p value.
9 FIFO: the "First In, First Out" priority queue. This queue ignores any
previously-marked priority that packets may have.
9 Fairness: the fairness algorithm ensures no starvation by granting all
packets a certain level of priority.
9 RED: the Random Early Detection algorithm utilizes statistical methods
to drop packets in a "probabilistic" way before queues overflow.
Dropping packets slows a source down enough to keep the queue
steady and reduces the number of packets that would be lost when a
queue overflows and a host is transmitting at a high rate.
9 WRR: Weighted Round Robin utilizes a process scheduling function that
prioritizes traffic according to the pre-defined 'Weight' parameter of a
traffic's class. This level of prioritizing provides more flexibility in
distributing bandwidth between traffic types, by defining additional
classes within a parent class.
e. Schedule: by default, the class is always active. However, you can configure
schedular rules to define time segments during which the class may be
active.
6. Under the 'Rx Traffic Policing' group, configure the following:
a. Rx Bandwidth: this parameter limits the device's bandwidth reception rate (from
the ISP).
