Configure the following parameters:
Name Enter the name of the class in this text box.
Class Priority The class can be granted one of eight priority levels, zero being the
highest and seven the lowest (opposite the rules priority levels). This level sets the
priority of a class in comparison to other classes on the device.
Tx Bandwidth Tx bandwidth is the reserved transmission bandwidth in kilobits
per second. The maximum allowed bandwidth can be limited by selecting Specify
from the drop-down list. The screen will refresh, adding another “Kbits/s” text
box. Enter the desired maximum allowed bandwidth.
Rx Bandwidth In the same manner, Rx bandwidth is the reserved reception
bandwidth, which can also be limited to a maximum allowed bandwidth.
Policy The class policy determines the policy of routing packets inside the class.
Select one of four options:
• Priority - Priority queuing utilizes multiple queues, so that traffic is distrib-
uted 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 an
802.1p value.
• FIFO - The “First In, First Out” priority queue. This queue ignores any pre-
viously marked priority the packets may have.
• Fairness - The fairness algorithm ensures no starvation by granting all pack-
ets a certain level of priority.
• RED - The RED (Random Early Detection) algorithm utilizes statistical
methods to drop packets in a “probabilistic” way before queues overflow.
Dropping packets in this way slows a source down enough to keep the queue
steady and reduces the number of packets lost when a queue overflows and a
host is transmitting at a high rate
Schedule By default, the class will always be active. However, scheduler rules can
be configured to define time segments during which the class may be active.
