To create a custom QoS profile to prioritize the traffic on the phoenix-VLAN segment and limit the rate of ingress traffic, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https:// .

Navigate to Networking > Segments > Switching Profiles and click Add Switching Profile. Select QoS as the profile type.

Enter a name and an optional description for the QoS profile, such as phoenix-QoS.

In the Mode section, select Untrusted as the mode from the drop-down menu. This will allow you to set a custom DSCP value for the outbound IP header of the traffic on the segment.

In the Priority section, enter 46 as the DSCP value. This will mark the traffic with Expedited Forwarding (EF) per-hop behavior, which is typically used for high-priority applications such as voice or video.

In the Class of Service section, enter 5 as the CoS value. This will map the DSCP value to a CoS value that can be used by VLAN-based logical ports or physical switches to prioritize the traffic.

In the Ingress section, enter 1000000 as the Average Bandwidth in Kbps. This will limit the rate of inbound traffic from the VMs to the logical network to 1 Mbps.

Optionally, you can also configure Peak Bandwidth and Burst Size settings for the ingress traffic, which will allow some burst traffic above the average bandwidth limit for a short duration.

Click Save to create the QoS profile.

Navigate to Networking > Segments and select the phoenix-VLAN segment that you want to apply the QoS profile to.

Click Actions > Apply Profile and select phoenix-QoS as the switching profile that you want to apply to the segment.

Click Apply to apply the profile to the segment.

You have successfully created a custom QoS profile and applied it to the phoenix-VLAN segment.
