2. To check the status of the SR-IOV cards:

   1. Navigate to Host > Manage.

   2. Select the tab Hardware.
      Ensure both the SR-IOV cards are in disabled state or the Passthrough must be in disabled state.

3. If the SR-IOV cards are not disabled, they must be disabled by performing following:

   1. Enable SSH. To enable SSH,

      1. Navigate to Host and select the tab Actions.

      2. From the drop-down list, select the option Services. Click Enable Secure Shell (SSH) and Enable console shell.

RSS Configuration for VMs using SR-IOV Interfaces

Receive side scaling (RSS) is a mechanism that enables spreading incoming network traffic incoming network traffic across multiple CPUs, thus eliminating a potential processing bottleneck. For SR-IOV configurations, the RSS configuration can must be updated in the ESXi host as follows:

1. Execute the following command to unload the IXGBE driver:
   esxcfg-module -u ixgbe
2. Execute the following command to verify the driver is unloaded:
   esxcfg-module -

1. l | grep ixg 
2. Execute one of the following commands to reload the driver with the required virtual function (VF) and RSS configurations:
   vmkload_mod ixgbe max_vfs=2,2

1. RSS=

1. 4,4 
     or 
   esxcfg-module -s 'max_vfs=2,2, RSS=4,4' ixgbe
2. Reboot the host to have RSS take effect. This modified configuration is retained after the reboot.

Installing the SBC Application on VMware

Once the VMware instance is created, you must install the SBC application.

Perform the following steps:

1. Select the Virtual Machine where you want to install the SBC application.

2. Click Edit. The Edit Settings window is displayed.

3. Select CD/DVD Drive 1.
