set switch tag vlan

Hi,

I'am installing esx 5.1.

I have 3 vlan (prod, vmotion, vmkernel). I look that when on dcui (yellow screen) I put  vlan correct, I cannot ping esx host. If  Iremove vlan tag I can ping esx host.

I suspect that someone doesn't work on switch (not managed by me).

How I can help network team? Which set  on the port of switch network team must be set?

thanks

Jonh
