The link status will be reported to vmkernel and vobd would take down these changes. It is not a supported configuration in ESXi/ESX 3.5, but it is supported in ESXi/ESX 4.x, ESXi 5.x and 6.0. It is possible to configure Jumbo Frames for an iSCSI network. ESX/ESXi supports frames up to 9000 Bytes. Here we are using vlan 10.Įsxcfg-vswitch -v 10 -p JumboFrames vSwitch1 When we did check vmkernel logs, MTU was constantly flipping between 15 grep - i changing MTU vmkernel. Any packet larger than 1500 MTU is a Jumbo Frame. The VLAN tag is specified after the -v in the example below. ![]() You can optionally assign a VLAN tag to the VMkernel port, if you are sharing this physical NIC with other networks.Next we’ll create a VMkernel port named JumboFrames on vSwitch1.To enable Jumbo Frames on the vSwitch run the following command. You will need to do these next steps from the Command Line Interface on the vSphere host server itself, hit ALT F1 to access the CLI.As your VMkernel port would have IP addresses attached to it for the management network (your connection to the host), you will need to create a brand new Virtual Switch first that has no VMkernel port added to it.The aim here is to add Jumbo Frames to a new VMkernel Port by adding a new VMkernel port with Jumbo Frames. Logon to the vSphere client > Inventory > Configuration > Networking > You will most likely have one Virtual Switch already configured. ![]()
