Packet Groupings
Verifying MAC-Based QoS Settings. To verify any of the MAC-based
QoS settings, use either the command
show fdb perm
or the command
show qosprofile <qosname>
This category of traffic groupings consists of the following:
Prioritization bits used in IEEE 802.1p packets
PACE packets
802.1p Packets. When traffic that contains 802.1p prioritization bits is
seen, the traffic is mapped to the four default QoS profiles. No user
configuration is required for this type of traffic grouping. This
grouping is available only in ingress mode.
