I have a device Netgear ReadyNAS 2100 that supports VLAN, I do communicate with this device ESX 4.1 via iSCSI protocol. Let me set the vmkernel of ESX Server on my Netgear the same VLAN to be sure that this NIC communicates only with the NAS Netgear on the same VLAN. Between ESX hosts and NAS Netgear, there is a switch Linksys. I have not experience on configuring VLAN tagged but I know well the theoretical functions. I world set the Netgear NAS VLAN "200" (for example) and vmkernel on the same VLAN "200" I do not know if I need to do some setting on the Linksys Switch (which has the default VLAN on all ports "0") or I can remain the same switch configuration and everything works anyway?
