To verify the procedure, view the (VM facing) port groups in VMware VCenter. In the following
example, the green icon represents UPLINK, and the blue icon represents the VM facing port
group:
Modifying the QoS settings
Modify QoS settings on the Cisco Nexus 1000V Switch and mark the service console and VMKernel
traffic with the appropriate QoS.
About this task
Policing and prioritization of traffic are implemented only when a policy map is applied to an interface. The
only exception is that by default, the QoS value for control and packet VLAN traffic is set to six. This value
can be overridden with an explicit QoS policy configured on the interface that carries the control and
packet VLAN traffic.
If the VSM VMs are not hosted on the VEM in an VMware vSphere ESXi host that it is managing (for
example, the VSM VMs are hosted on separate VMware vSphere ESXi hosts running the regular VMware
vSwitch), packets from the VSM are not covered by the QoS policies configured on the Cisco Nexus
1000V DVS. To ensure proper QoS treatment, the VSM packets configure and attach QoS policy on the
switchports of the physical switches connected the VMware vSphere ESXi hosts where the VSM VMs are
hosted.
This QoS policy colors and marks the control packets only. The upstream switches must be configured
with the proper QoS per-hop-behavior to ensure differentiated services.
