Configuring Traffic Classes

7.10 CONFIGURING TRAFFIC CLASSES
IEEE 802.1p defines up to 8 separate traffic classes. This switch supports Quality of Service (QoS)
by using two priority queues, with weighted fair queuing for each port. You can use the 802.1P
Configuration Menu screen (Figure 7-14) to access the screens to configure the default priority for
each port, or to display the mapping for the traffic classes as described in the following sections.
Also, refer to Appendix C, for information on Class of Service.

7.10.1 Port Priority Configuration

The default priority for all ingress ports is zero. Therefore, any inbound frames that do not have
priority tags will be placed in the low priority output queue. Default priority is only used to
determine the output queue for the current port; no priority tag is actually added to the frame. You
can use the 802.1P Port Priority Configuration menu screen (Figure 7-15) to adjust the default
priority for any port.
