|20033,AP: Native VLAN id should be same accross the APs in Flex group.|
The setting of the switch port connected to the AP is VLAN1.
Is there a problem??
Well you are using the tool that scrubs your configuration that you uploaded. Take a look at your config and search for native vlan and see if maybe you have something there. Are you also uploading multiple configs to the tool or just one.
I don't understand why you are using vlan 1 for everything? That is not an ideal design to implement. You should put your ap's in a management vlan or own its own if possible and each ssid should also be on its own vlan/subnet.
