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.
- Enable the software simulation of TSO in the VMkernel.
