Determine Whether LRO Is Enabled for VMXNET3 Adapters on an ESXi Host

Examine the status of LRO on an ESXi when you estimate the networking performance on a host that runs latency-sensitive workloads.

Prerequisites

Procedure

1. In the vSphere Client, navigate to the host.
2. On the Configure tab, expand System.
3. Click Advanced System Settings.
4. Examine the value of the LRO parameters for VMXNET2 and VMXNET3.
   • For hardware LRO, examine the Net.Vmxnet3HwLRO parameter. If it is equal to 1, hardware LRO is enabled.
   • For software LRO, examine the Net.Vmxnet3SwLRO parameter. If it is equal to 1, hardware LRO is enabled.
