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.

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.
