ESXi 5 VLAN VST mode configuration issue

[Dianno]

Hi, im trying to configure 2 vlans 1600 and 1601 for 2 vms

it works fine in VGT mode on portgroup with VLAN ID 4095

here is the config:

But i think it would be much better to use VST mode because i have only 2 vlans and access to all vlan range is unnecessary

the configuration for VST is

But it doesnt work at all, my vms cant ping their default routers and each other

Configrutaion:

ESXi 5 Server

1 port on a physical switch set in trunk mod with standard IEEE 802.1Q for VLANS 1600 and 1601 (both vlan subnets with 25 prefix length)

100Mbit full duplex auto negotiate

2 VMs with Linux RHLE 5.8

NIC teaming on bond0 and vlan interfaces bond0.1600 and bond0.1601

cxgb3i network driver with 8021q module

How can i resolve this issue?

Best regards

Dmitri

With VLAN 4095 traffic is passed through to the VMs including the VLAN tag. If you set the VLAN-ID on the port group, the VLAN tag will be removed by the port group already, so you'll have to disable the virtual guest tagging to make this work.

If there still is guest internal tagging done then this as a.p. said most likely the cause.

When defining a VLAN id on a portgroup the vSwitch expects all incoming frames from the VMs to be untagged. Any tagged frames are dropped at vSwitch level.
