  • TCP Segmentation Offload question

    Hi,

    From the documentation, it is written that the TSO is enabled by default in the VMkernel.

    I checked using esxcfg-vmknic -l

    And it is correct that the TSO is enabled (TSO MSS = 65535).

    Also stated in the documentation, the VM should use Enhanced VMXNET (VMXNET2).

    My questions:

    1. If the VM is using Flexible, then TSO will not have any effect, correct?

    2. What's the deal with the NIC setting in the guest OS? Because if I checked, the "VMware Accelerated AMD PCNet Adapter" has setting for "TsoEnabled" and current value is "1".

    Do I need to set the Guest OS NIC setting "TsoEnabled" to "0" in order to properly disable the TSO?

    Thanks.
Working...
