Hi Team,

I found that 2 of client switches suddenly went offline and came back online, which have almost 56 cnPilot WAPs connected combined.
While seeing switch logs, i found below error. If anyone is aware of it and how we can troubleshoot further? FYI, we configured WAPs via PBA with MAC-OUI.

Shot in the dark here, not familiar with these switches, but does the cnPilot have dynamic learning for vlans?

Hi,

Same device was moving between switch ports. Ex: device with mac address ee:b8:cf:cc:60:65 was migrating between ports 42 & 49. Was this device roaming between the 2 APs?

Please send the tech-support logs of APs that are connected to switch ports 42 and 49, the switch configurations of the cnMatrix switch to niraj.mahapatra@cambiumnetworks.com

Hi Tam,

I think so, I was checking with Shiv yesterday as well and we found that, these switches uplink ports are having management VLAN as native PVID, which may causes triggers this issue. I know, it is not impacting anything at the moment, but just double confirming about it.
