Traffic Class Configuration
The Traffic Class Configuration menu is used to map incoming packets with 802.1p priority tags to one
of the 4 hardware queues used on the Switch.
Figure 6- 28. Traffic Class Configuration window
This window allows you to configure traffic class priority by specifying the class value, from 0 to 3, of
the Switch
’
s eight levels of priority.

Traffic class configuration uses the CLI command
config 802.1p user_priority
. To view the
existing configuration use the CLI command
show 802.1p user_priority
.
QoS Output Scheduling Configuration
QoS can be customized by changing the output scheduling used for the hardware queues in the
Switch. As with any changes to QoS implementation, careful consideration should be given to how
network traffic in lower priority queues are affected. Changes in scheduling may result in unacceptable
levels of packet loss or significant transmission delay. If you choose to customize this setting, it is
important to monitor network performance, especially during peak demand as bottlenecks can quickly
develop if the QoS settings are not suitable.
Figure 6- 29. QoS Output Scheduling Configuring
The MAX. Packets field specifies the number of packets that a queue will transmit before surrendering
the transmit buffer to the next lower priority queue in a round-robin fashion.
