I am trying to understand why this doesn't seem to work as I am thinking it should. I am in the middle of implementing VLAN in order to seclude different traffics such as voice, server, workstations... and I am still trying to understand how the un/tagging works
Here is the setup:
ESX Server on Dell SW with default VLAN 1 - so everything is untagged in VLAN 1 I have an LACP using p17-18
HP Procurve Server SW with default VLAN 1 - again everything is untagged in VLAN 1 I also have an LACP. the LACP status is active and good. the LACP trunk is in VLAN 1. I have a trunk to the Core switch below aka Trk1, this Trk1 is in VLAN 1.
HP procurve Core SW with default VLAN 1 - all is untagged in VLAN 1 I have a trunk to the server switch above aka Trk1, this Trk1 is in VLAN1. VLAN has a DHCP, through IP helpers.
My issue: Setting up a vSwitch in ESX not using tagging, everything works fine. Seeting up a vSwitch in ESX using tagging (here VLAN1), I loss connectivity to/from that VM.
I imagined that the explicit tagging of that virtual switch would not impact anything, but somehow it does and I do not understand why.
Did I miss something obvious?
