Quality of Service
ExtremeWare XOS 11.1 Concepts Guide

Changing the default 802.1p mapping. By default, a QoS profile is mapped to a queue, and each QoS
profile has configurable parameters. In this way, an 802.1p priority value seen on ingress can be
mapped to a particular QoS profile.
To change the mapping of 802.1p priority value to QoS profile, use the following command:
configure dot1p type <dot1p_priority> {qosprofile} <qosprofile>
Replacing 802.1p priority information. By default, 802.1p priority information is not replaced or
manipulated, and the information observed on ingress is preserved when transmitting the packet. This
behavior is not affected by the switching or routing configuration of the switch.
NOTE
In the Aspen 8810 switch, 802.1p replacement uses existing flow classifiers. If this feature is enabled and the flow
classifier has been defined (traffic groupings), the related flow classifier causes the replacement.
However, the switch is capable of inserting and/or overwriting 802.1p priority information when it
transmits an 802.1Q tagged frame. If 802.1p replacement is enabled, the 802.1p priority information that
is transmitted is determined by the queue that is used when transmitting the packet. The 802.1p
replacement configuration is based on the ingress port. To replace 802.1p priority information, use the
following command:
enable dot1p replacement ports [<port_list> | all]
NOTE
The port in this command is the ingress port.
To disable this feature, use the following command:
disable dot1p replacement ports [<port_list> | all]
NOTE
On the Aspen switch, only QP1 and QP8 exist by default; you must create QP2 to QP7. If you have not created
these QPs, the replacement feature will not take effect.
