VMware: Edit MTU settings by GUI in vSphere 5.0

I saw it’s possible since vSphere 5 to configure the MTU size via the VI Client, sometimes it would be handy to do this with a GUI. In vSphere 4 you configure this at the console (vicfg-vswitch –m 9000 vswitch0 & esxcfg-vmknic –l )

  1. Any MTU over 1500 is a “jumbo frame”, and your network switch as well as your SAN must be programmed to use the same MTU size, otherwise it’s pointless to change this in VMWare. Beware, some older switches don’t support jumbo frames.

    Correct, you need to configure SAN, Storage switches and vSwitches + Virtual Machine.. tip update the vSwitch frist
