Enable or Disable Software TSO in the VMkernel

If a physical network adapter experiences problems with TSO, you can temporarily enable the software simulation of TSO in the VMkernel until you troubleshoot the problems.

Procedure

• ♦ Run these esxcli network nic software set console commands to enable or disable the software simulation of TSO in the VMkernel.
  • Enable the software simulation of TSO in the VMkernel.

    esxcli network nic software set --ipv4tso=1 -n vmnicX
    esxcli network nic software set --ipv6tso=1 -n vmnicX

  • Disable the software simulation of TSO in the VMkernel.

    esxcli network nic software set --ipv4tso=0 -n vmnicX
    esxcli network nic software set --ipv6tso=0 -n vmnicX

  where X in vmnicX represents the number of the NIC ports on the host.

  The configuration change persists across host reboots.
