Yes, it wasn't ACS related, it was the switch. I split the management traffic and the public/guest traffic into 2 different bridges, trunk mode, all vlans are now transported as they should.
Thanks for the help guys! -----Original Message----- From: Alex Mattioli <[email protected]> Sent: Wednesday, July 24, 2024 4:20 PM To: [email protected] Subject: RE: No network if VR and VM are on different hosts It doesn't sound like it's ACS related. With access ports it would definitely not work. Have you created all VLANs in the switch?

I even tried with plain, access ports, and only one interface on the host bridge, it's the same issue, the cloud0 bridge does not come up, it's either down or unknown. I really don't know where to go from here, never had this issue while testing and I did like 1000 installations on identical hardware, same host os. The only difference that I can think of is the ACS version, in testing I used 4.19.0 and now 4.19.1, but I don't think this is relevant since it doesn't seem like other users experienced this issue.

The switch ports need to be configured as trunk mode. -Wei On Tuesday, July 23, 2024, Alexandru Stan <[email protected]> wrote: > Hello.
