Subject RE: ACS Multiple Xen Clusters / Pools

Hi Praveen,

Thanks for your feedback. I did indeed set all guest VLANs on all the switches, this is why
I thought about searching somewhere else.
Anything else I might have skipped?

Hi Patrick,

It seems the guest VLANs are not enabled on all inetrmittent switches between these clusters.
Please check them on your physical switches.

Guest VLANs are common across entire zone and they must be enabled in all the switches which
are part of that zone to allow guest VM communication.
