By default, the show command
outputs automatically list No-override for priority
options that have not been configured. This means that if you do not
configure a priority for a specific option, QoS does not prioritize
packets to which that option applies, resulting in the No-override state.
IP packets received through a VLAN-tagged port are
managed using the 802.1p priority they carry in the 802.1Q field in
their headers.
VLAN-tagged packets received through an untagged port
are handled by the switch with “normal” priority.
the show qos vlan-priority output shows the global QoS configurations on the switch that are
configured with the VLAN ID classifier. Note that non-default 802.1p
priorities have been configured for VLAN IDs 22 and 33; packets received
on VLAN 1 are managed with the default settings, as described in the
two bulleted items above.Output for the show qos vlan-priority command
