Traffic Groupings and Creating a QoS Policy

802.1p Packets
When traffic that contains 802.1p prioritization bits is seen, the traffic is
mapped to the eight default QoS profiles. No user configuration is
required for this type of traffic grouping. Table 2 7
describes 802.1p values
and their associated QoS profiles.
To modify the default behavior of 802.1p values and associated QoS
profiles, use the following commands:
config dot1p type <dot1p_value> qosprofile <qosname>
This command changes the default mapping of 802.1p values and QoS
profiles.
enable dot1p replacement ports [<portlist> | all]
This command allows the switch to overwrite the ingress 802.1p value
with the value configured for the QoS profile.
