We have Meraki MR36H accesspoints with "wired_only" SSIDs connected to our MX95 custer. When a device is connecting to one of the physical ports, it authenticate and gets the correct vlan by asking our Cisco ISE. This works fine and we can run both MAB lists and dot1x. However, after some time the vlan number disapears in the client list and it's says "native" (see image). The device stops working and the only way to get it back is to reboot the AP 1 or 2 times. We monitor the devices by pinging them. The Meraki log is clean. I tested to set a vlan under "vlan tagging ID" and that works, even though I get an error msg while saving changes. Any ideas?
We are running firmware 30.7 in the AP.
