I've made some progress!
I assigned the cAP an IP from my Admin LAN (VLAN1). I also created a "Wireless"-configuration and a "Provisioning" -config in CAPsMAn
I changed CAPsMAN Interface to VLAN1.
Radio is connected and it seems to be working with the admin LAN.
But now I wanted to assign different VLANs to the cAP:
All VLANs are configured on RB3011 on the same bridge with VLAN-filtering and are trunked via SFP to an Cisco-Switch, where ether1 of the cAP is connected over an untagged VLAN1-Port-
The Admin LAN (VLAN1) should not be broadcasted via radio; this is only for the AP itselves. VLAN 60, VLAN70, and VLAN99 should be broadcasted, via radio, but I am not sure, how this can be realized. Can someone hlep here?
