Some properties may not be configurable for all system classes. Update the following properties for the system class you want to configure to meet the traffic management needs of the system: Note In the Navigation pane, click the LAN tab.

On ESXi, there seems to be a glitch in creating a vmkernel port on a vDS through the vcli, so the workaround is to create a vmkernel interface with MTU 9000 on a standard switch and then migrate it over to the vDS through the vSphere Client.You can get the status (name/address/mask/MAC addr/MTU) of the vmkernel interfaces viaĢ) Configure the MTU – it is a QoS System Classes property Use the esxcfg-vmknic command to delete and then add a vmkernel interface with an MTU of 9000.Enable jumbo frames on the vmkernel ports Set the “Maximum MTU” to the desired MTU (e.g. From the Networking inventory menu, select the vDS and then “Edit Settings”. For vDS (vNetwork Distributed Switch), you can set the MTU via the vSphere Client UI.Use “ vicfg-vswitch –l” to list the vswitches and their properties For example, this cli command will set the MTU to 9000 bytes for the vSS named “vswitch0”: For vSS (standard vSwitch) you need to use the vSphere cli.Enable jumbo frames on the virtual switch (set the MTU on the uplinks/physical NICs) Switch(config-sys-qos)# service-policy type network-qos jumboġ.
