You can configure HCX to associate a traffic group with an Uplink Network in the Service Mesh for improved migration or workload bandwidth.
By default, VMware HCX uses the management network for all uplink traffic. By overriding the default Uplink Network for the destination site with a specific traffic group, you isolate traffic for the HCX service. By isolating network traffic in this way, you gain any performance advantage by separating the traffic and utilizing the available bandwidth of the T0 router. For example, you can isolate migration and workload traffic by creating one Service Mesh for Bulk Migration and one Service Mesh for Network Extension. Within each specific Service Mesh, you then configure a unique traffic group for the Uplink Network.
Prerequisites
Each SDDC is configured with traffic groups.
A separate Service Mesh exists for each HCX service that is using traffic groups. For more information about creating and modifying a Service Mesh, see Create a Service Mesh for vSphere-based Site Pairs.
Procedure
Results
The HCX services activated in the Service Mesh are configured to use the T0 gateway created by the traffic group.
Before you can delete a traffic group from an SDDC, you must either delete the HCX Service Mesh that is using the traffic group or override the Uplink Network in the Service Mesh with a different network.
What to do next
Repeat this procedure to isolate traffic and enhance bandwidth for other HCX services.
