Hello ch06,   The range limits can be found here. Page 25 [URL] You can enable jumbo frames by setting an MTU value greater than 1500. You cannot set an MTU size greater than 9000 bytes   Also you need to be configured the same on both ends : [URL]  
Hi all, I search to change the MTU value with the command: "esxcli network vswitch standard set --mtu=1250 -v vSwitch0", but he returns: « Unable to set MTU. Valid MTU values are 1280-9190".   I understand the msg, but I need to found why, and a command to show the limits of the MTU range.   Thank's Again. 
Change MTU under 1500
