Information About VLAN QoS
On Cisco Nexus devices, you can configure quality of service (QoS) policies for classification and marking
on VLANs. The policies that you apply to a VLAN are applied to the traffic on the VLAN's Layer 2 and
switch virtual interface (SVI) ports.
Precedence of QoS Policies
The marking requirements in a QoS policy determine its precedence. Interface QoS policies take the highest
precedence, the VLAN QoS policies are next, and the System QoS policies have the lowest precedence.
However, if a VLAN is assigned both a VLAN QoS policy and a VLAN ACL (VACL), the VACL takes the
highest precedence.
