You configure QoS only on physical ports; there is no support for it at the VLAN level.
Control traffic (such as spanning-tree bridge protocol data units [BPDUs] and routing update
packets) received by the switch are subject to all ingress QoS processing.
You are likely to lose data when you change queue settings; therefore, try to make changes when
traffic is at a minimum.
Purpose
Enter global configuration mode.
Enable QoS globally.
QoS runs with the default settings described in the
