Configuring Gateway QoS


Article ID: 324160


Updated On:




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 focusses on how to apply it at the Gateway.

  • 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 Yier-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.


On the NSX UI, create a QoS profile by navigating to Networking 0 -> Networking Profiles -> Gateway QoS -> Add Gateway QoS Profile


Navigate to Networking -> Tier-1 Gateways, select the Tier-1 and edit settings.
Expand Additional Settings and select the QoS profile that was just created.


Save and Exit the configuration

QoS is applied at the Router links, these are the links conencting the Tier-1 and Tier-0 Gateways, specifically the uplink of the T1 and the downlink of the T0.
All traffic coming in or going out of this interface will be rate limited based on the QoS profile configuration.
