To support RSS on ixgbe NICs, your environment must meet these prerequisites.
- vSphere 5.1 or later, with vSphere Web Client installed.
- ixgbe driver 3.7.13.6 or later
To create a host profile that sets the values for the RSS kernel module parameter, as follows.
- In the vSphere Web Client, click Rules and Profiles and click Host Profiles.
- Click Edit Host Profile and expand the General System Settings folder.
- Expand Kernel Module Configuration, select Kernel Module and select ixgbe.
- Select Kernel Module Parameter > RSS and set the value to a comma-separated list that specifies the number of queues for each port, in sequence. For example, for two ports with 4 queues each, set the value to 4,4. If a system has 5 ixgbe ports named vmnic6, vmnic7, vmnic8, vmni9, and vmnic 10, and you want to enable RSS for vmnic7 and vmnic8, then the value is 0,4,4,0,0.
- Click Finish.
- Reboot the ESXi host.
