Change the size of the maximum transmission unit (MTU) on a vSphere Standard Switch to improve the networking efficiency by increasing the amount of payload data transmitted with a single packet, that is, enabling jumbo frames.

Procedure

  1. In the vSphere Web Client, navigate to the host.
  2. On the Manage tab, click Networking, and select Virtual switches.
  3. Select a standard switch from the table and click Edit settings.
  4. Change the MTU (bytes) value for the standard switch.

    You can enable jumbo frames by setting MTU (bytes) to a number greater than 1500. You cannot set an MTU size greater than 9000 bytes.

  5. Click OK.
