DOT1X_SWITCH-5-ERR_VLAN_NOT_FOUND appearing quite often on a 3850 stack
I'm getting quite a lot of log entries like this one:
Jan 29 12:12:09 172.30.32.170 908850: 478419: 003167: Jan 29 12:13:36: %DOT1X_SWITCH-5-ERR_VLAN_NOT_FOUND: Attempt to assign non-existent or shutdown VLAN 10 to 802.1x port GigabitEthernet3/0/12 AuditSessionID AC1E20AA000F5B6C3301C642 (vxs12a1-3)
A few of those log entries also point to VLAN 40 not being found or shutdown.
This is not true, as both VLANs exist on this switch and are correctly working... so my question is: what should this mean and where should I take a deeper look at?
