The NSX QoS feature can be used to prioritize sufficient bandwidth for preferred traffic, controlling latency and jitter, and reducing data loss for preferred packets even when there is a network congestion. This level of network service is provided by using the existing network resources efficiently.
QoS can be applied at either the Segment or the Gateway level, this article focuses on how to apply it at the Gateway.
Note:
- Gateway QoS profile is supported only on Tier-1 gateways.
- QoS policies on Tier-1 gateways apply only to north-south traffic and not to Tier-1 gateway overlay segments or service interfaces.
- The Tier-1 gateways must be in active-standby mode with an NSX Edge cluster.
- QoS profile is not supported on Tier-1 gateways that are configured for distributed routing only.
